Abstract

A displacement switch includes a main operation portion having a hollow shape. The main operation portion includes a top surface via which the displacement switch is operated, and a side surface connected to the top surface to define the hollow shape. The displacement switch also includes a support member connected to the main operation portion and swingable around a swing axis together with the main operation portion, and a base including a peripheral wall surrounding an insertion inlet into which the support member is inserted. The main operation portion covers the insertion inlet such that the side surface surrounds an outer peripheral surface of the peripheral wall.

First claim

What is claimed is:

1. A displacement switch comprising:
a main operation portion having a hollow shape that comprises:
a top surface via which the displacement switch is operated; and
a side surface connected to the top surface to define the hollow shape;

a support member connected to the main operation portion and swingable around a swing axis together with the main operation portion; and
a base including a peripheral wall surrounding an insertion inlet into which the support member is inserted,
wherein the main operation portion covers the insertion inlet such that the side surface surrounds an outer peripheral surface of the peripheral wall.

2. The displacement switch according to claim 1 , wherein
the peripheral wall includes a peripheral wall top surface opposite to the top surface of the main operation portion in a height direction of the displacement switch, and
the insertion inlet is hollowed from the peripheral wall top surface.

3. The displacement switch according to claim 2 , wherein
the side surface has a top edge connected to the operation surface and a bottom edge opposite to the top edge in the height direction, and
the insertion inlet is provided between the top edge and the bottom edge in the height direction.

4. An operation device comprising:
a grip portion;
a head portion disposed on the grip portion;
a displacement switch disposed on the head portion, the displacement switch being swingable about a swing axis or slidable in a width direction of the displacement switch, the displacement switch comprising:
a main operation portion having a hollow shape that comprises:
a top surface via which the displacement switch is operated; and
a side surface connected to the top surface to define the hollow shape;

a support member connected to the main operation portion to support the main operation portion to move together with the main operation portion; and
a base including a peripheral wall surrounding an insertion inlet into which the support member is inserted,
wherein the main operation portion covers the insertion inlet such that the side surface surrounds an outer peripheral surface of the peripheral wall.

5. The operation device according to claim 4 , wherein
the head portion includes:
at least two operation tools; and
an installation portion for installation of the operation tools, one of the operation tools serving as a lower operation tool disposed on a side of the grip portion, another of the operation tools serving as an upper operation tool disposed on a side of a top portion of the head portion, and

a first operation detecting position for the lower operation tool is located on a side closer to the installation portion than a second operation detecting portion for the upper operation tool.

6. The operation device according to claim 4 , wherein
the head portion includes:
at least two operation tools; and
an installation portion for installation of the operation tools, one of the operation tools serving as a lower operation tool disposed on a side of the grip portion, another operation tool serving as an upper operation tool disposed on a side of a top portion of the head portion,

the upper operation tool includes a second operation surface, and
the lower operation tool includes a first operation surface located on a side closer to the installation portion than the second operation surface.

7. The operation device according to claim 4 , wherein
the head portion includes:
an operation tool to be operated; and
an installation portion for installation of the operation tool, the installation portion being inclined lowering on a near side than on a far side opposed to the near side from the far side toward the near side, and being inclined to be closer to the far side on an inner side than on an outer side in the width direction from the near side toward the far side.

8. The operation device according to claim 4 , wherein
the head portion includes at least two operation tools arranged on both sides of an extension line formed by extending an axis of the grip portion, and the operation tools locating a center portion between the operation tools on an inner side with respect to the extension line in the width direction and inclining a center line passing through the center portion toward the inner side with respect to the extension line in the width direction.

9. The operation device according to claim 4 , wherein
a grip portion has a back surface,
the head portion includes an operation tool, and
a guide portion is formed on the back surface of the grip portion to be curved gradually shifting outward along a direction from a lower side of the grip portion to an upper side of the grip portion in the width direction and gradually shifting inward along a direction from an intermediate portion of the grip portion to the upper side in the width direction, the guide portion being to guide gripping of the grip portion.

10. The displacement switch according to claim 4 , wherein
the peripheral wall includes a peripheral wall top surface opposite to the top surface of the main operation portion in a height direction of the displacement switch, and
the insertion inlet is hollowed from the top surface.

11. The displacement switch according to claim 10 , wherein
the side surface has a top edge connected to the operation surface and a bottom edge opposite to the top edge in the height direction, and
the insertion inlet is provided between the top edge and the bottom edge in the height direction.

12. An operation device comprising:
a grip portion;
a head portion disposed on the grip portion;
a displacement switch disposed on the head portion, the displacement switch being swingable about a swing axis or slidable in a width direction of the displacement switch, the swing axis being substantially perpendicular to the width direction, the displacement switch having a T-shaped configuration including:
a main operation portion extending along the width direction, the main operation portion including an operation surface via which the displacement switch is operated; and
a subordinate operation portion extending from the main operation portion along a direction perpendicular to the width direction to move integrally with the main operation portion;

a base mounting the main operation portion, the base overlapping the third wall of the main operation portion viewed in a first direction perpendicular to the third wall; and
a support member to support the main operation portion and the subordinate operation portion swingably around the swing axis together with the main operation portion, wherein
the base includes a peripheral wall surrounding an insertion inlet into which the support member is to be inserted, the main operation portion covering the insertion inlet such that the first wall, the second wall, and the third wall surrounds the peripheral wall.

13. An operation device comprising:
a grip portion;
a head portion disposed on the grip portion;
a displacement switch disposed on the head portion, the displacement switch being swingable about a swing axis or slidable in a width direction of the displacement switch, the swing axis being substantially perpendicular to the width direction, the displacement switch having a T-shaped configuration including:
a main operation portion extending along the width direction, the main operation portion including an operation surface via which the displacement switch is operated; and
a subordinate operation portion extending from the main operation portion along a direction perpendicular to the width direction to move integrally with the m
