Abstract

An operation apparatus includes a supporting element, an operation element including an arm whose basal end is rotatably supported by the supporting element and whose tip is provided with an acting element, and a return spring provided between the supporting element and the operation element, in which the return spring is housed in a compact manner without inviting an increase in the number of components. A return spring is provided between a first spring holder and a second spring holder. A supporting element is provided with a first side wall opposing the return spring in the lateral direction. An arm is provided with a second side wall opposing the first side wall and surrounding the return spring in conjunction with the first spring holder, the second spring holder, and the first side wall.

First claim

What is claimed is:

1. An operation apparatus comprising:
a return spring that is a wave spring;
a supporting element including:
a first side wall opposing the return spring in a lateral direction; and
a first spring holder; and

an operation element including:
an arm including:
a basal end rotatably supported by the supporting element;
a second spring holder;
a second side wall being planar and having an inner surface facing the first side wall; and
an acting element disposed at a tip of the arm,

wherein the return spring is surrounded with the first spring holder, the second spring holder, the first side wall, and the second side wall,
wherein the first side wall and the second side wall extend in a first direction and are spaced from each other in a second direction,
wherein the first spring holder extends from the first side wall in the second direction, and
wherein the second spring holder extends from the inner surface of the second side wall in the second direction and is spaced from the first spring holder in the first direction; and
wherein the second spring holder is the only element extending from the inner surface of the second side wall.

2. The operation apparatus according to claim 1 , wherein a radial direction width of the return spring becomes greater than its expansion-compression direction length when compressed.

3. The operation apparatus according to claim 2 , wherein the return spring is provided between the supporting element and the operation element having its expansion-compression direction oriented in a tangent direction of a virtual arc about a rotation axis line of the operation element.

4. The operation apparatus according to claim 3 , wherein the second side wall extends in a radial direction relative to the rotation axis line of the operation element.

5. The operation apparatus according to claim 4 , wherein the supporting element is provided with a recess housing part of the return spring.

6. The operation apparatus according to claim 1 ,
wherein the return spring extends in the second first direction between the first spring holder and the second spring holder.

7. The operation apparatus according to claim 1 , wherein the return spring is compressed in the first direction, and wherein the first side wall and the second side wall are parallel to each other.

8. The operation apparatus according to claim 1 , wherein the second spring holder has a first end connected to the second side wall and a second free end.

9. An operation apparatus comprising:
a return spring that is a wave spring;
a supporting element including:
a first side wall opposing the return spring in a lateral direction; and
a first spring holder; and

an operation element including:
an arm including:
a basal end rotatably supported by the supporting element
a second spring holder;
a second side wall opposing the first side wall; and
an acting element disposed at a tip of the arm,

wherein the return spring is surrounded with the first spring holder, the second spring holder, the first side wall, and the second side wall,
wherein the first side wall and the second side wall extend in a first direction and are spaced from each other in a second direction,
wherein the first spring holder extends from the first side wall in the second direction, and
wherein the second spring holder extends from the second side wall in the second direction and is spaced from the first spring holder in the first direction,
wherein a radial direction width of the return spring becomes greater than its expansion- compression direction length when compressed,
wherein the supporting element is a step-use stay fixed to a vehicle body frame of a saddled vehicle,
wherein the step-use stay supports a step disposed on an outer side in a vehicle width direction of the step-use stay,
wherein the step-use stay is provided with, on an inner side in the vehicle width direction of the step-use stay, a pedal shaft rotatably supporting the operation element being a brake pedal, and
wherein the return spring is provided between the operation element and the step-use stay on the inner side in the vehicle width direction of the step-use stay.
wherein the supporting element is a step-use stay fixed to a vehicle body frame of a saddled vehicle,
the step-use stay supports a step disposed on an outer side in a vehicle width direction of the step-use stay,
the step-use stay is provided with, on an inner side in the vehicle width direction of the step-use stay, a pedal shaft rotatably supporting the operation element being a brake pedal, and
the return spring is provided between the operation element and the step-use stay on the inner side in the vehicle width direction of the step-use stay.

10. An operation apparatus comprising:
a supporting element;
an operation element including an arm whose basal end is rotatably supported by the supporting element and whose tip is provided with an acting element; and
a return spring provided between the supporting element and the operation element,
wherein the return spring being a wave spring is provided between a first spring holder provided at the supporting element and a second spring holder provided at the arm,
wherein the supporting element is provided with a first side wall opposing the return spring in a lateral direction,
wherein the arm is provided with a second side wall opposing the first side wall and surrounding the return spring in conjunction with the first spring holder, the second spring holder, and the first side wall,
wherein the supporting element is a step-use stay fixed to a vehicle body frame of a saddled vehicle,
wherein the step-use stay supports a step disposed on an outer side in a vehicle width direction of the step-use stay,
wherein the step-use stay is provided with, on an inner side in the vehicle width direction of the step-use stay, a pedal shaft rotatably supporting the operation element being a brake pedal, and
wherein the return spring is provided between the operation element and the step-use stay on the inner side in the vehicle width direction of the step-use stay.
