Abstract

An inserting apparatus of the present invention includes a base provided in an insertion section, a first recess provided in the base, an opening forming surface formed around the first recess, a movable member configured to move in the first recess, a tabular lid member configured to close an opening of the first recess, a second recess provided in the lid member, a wall surface provided on the base, and opposed to at least a part of a side surface of the lid member in a state in which the contact surface is in contact with the opening forming surface, a fixing resin fixing the lid member to the base, and one or a plurality of protrusions provided on the side surface, having thickness smaller than thickness in the side surface of the lid member, and projecting toward the wall surface.

First claim

What is claimed is:

1. An inserting apparatus comprising:
a base provided in an insertion section inserted into a subject;
a first recess recessed on a surface of the base;
an opening forming surface formed around an opening of the first recess on the surface of the base;
a movable member configured to move with respect to the base in the first recess, a part of the movable member projecting from the opening of the first recess;
a tabular lid member including a contact surface larger than the opening of the first recess and in contact with the opening forming surface, the lid member closing the opening of the first recess by the contact surface coming into contact with the opening forming surface;
a second recess recessed on the contact surface of the lid member, the second recess forming a housing space including the movable member by connecting the second recess to the first recess in a state in which the lid member closes the opening of the first recess;
a wall surface provided on the base, erected toward an outer side of the base from the opening forming surface, and opposed to at least a part of a side surface of the lid member in a state in which the contact surface is in contact with the opening forming surface;
a fixing resin disposed at least in a gap between the side surface of the lid member and the wall surface in the state in which the contact surface is in contact with the opening forming surface, the fixing resin fixing the lid member to the base; and
one or a plurality of protrusions provided in one of the side surface of the lid member and the wall surface, having thickness smaller than thickness in the side surface of the lid member, and projecting from the one of the side surface of the lid member and the wall surface toward another of the side surface of the lid member and the wall surface.

2. The inserting apparatus according to claim 1 , wherein
the opening forming surface includes a surface formed on a side surface of the base and extending in a longitudinal axis direction of the insertion section,
the movable member is movable within a predetermined moving range in the longitudinal axis direction with respect to the base,
the wall surface is disposed to hold, in the longitudinal axis direction, the lid member in a state in which the contact surface is in contact with the opening forming surface, and
the plurality of protrusions are disposed to project in both directions of the longitudinal axis direction from the side surface of the lid member.

3. The inserting apparatus according to claim 1 , wherein the protrusion is provided in the lid member and disposed to be separated in a thickness direction from an outer surface on an opposite side of the contact surface of the lid member.

4. The inserting apparatus according to claim 1 , wherein the protrusion is provided on the wall surface and disposed to be separated in a thickness direction from an end face of the wall surface.

5. The inserting apparatus according to claim 2 , wherein
at least one of both ends in the moving range of the movable member is decided by a position where the movable member is in contact with a restricting section that is a part of a sidewall of the first recess, and
an opening width in the longitudinal axis direction of the second recess is larger than an opening width of the first recess, and a sidewall of the second recess is disposed to be separated in the longitudinal axis direction from the movable member in a contact state with the restricting section.

6. The inserting apparatus according to claim 1 , wherein
the opening forming surface includes a pair of planes parallel to a longitudinal axis direction of the insertion section and disposed at angles at which the pair of planes cross each other, and
the contact surface of the lid member includes a pair of planes respectively in contact with the pair of planes of the opening forming surface.

7. The inserting apparatus according to claim 1 , wherein the inserting apparatus is an endoscope.

8. The inserting apparatus according to claim 1 , wherein
the opening forming surface is formed on a side surface of the base in a longitudinal axis direction of the insertion section, and
the wall surface is provided to cross, in the longitudinal axis direction, the lid member in a state in which the contact surface is in contact with the opening forming surface.

9. The inserting apparatus according to claim 1 , wherein
the opening forming surface of the base is formed larger than the contact surface of the lid member, and
an entire surface of the contact surface is in contact with the opening forming surface.

10. The inserting apparatus according to claim 1 , wherein
the movable member is provided to move in a moving range, the moving range being a predetermined range, with respect to the base, and
at least one of both ends defining the moving range is a part of a sidewall of the first recess in contact with the movable member.

11. The inserting apparatus according to claim 1 , wherein a thickness of a part including the contact surface of the lid member is formed greater than a thickness of a center portion forming a bottom surface of the second recess in a direction in which the bottom surface of the second recess extends.

12. The inserting apparatus according to claim 1 , wherein the opening forming surface is formed to surround a circumference of an opening of the first recess.

13. An inserting apparatus comprising:
a base provided in an insertion section inserted into a subject;
a first recess recessed on a surface of the base;
an opening forming surface formed around an opening of the first recess on the surface of the base;
a movable member configured to move with respect to the base in the first recess;
a lid member including a contact surface in contact with the opening forming surface, the lid member closing the opening of the first recess;
a second recess provided in the lid member, the second recess covering the movable member when the second recess is connected to the first recess in a state in which the opening of the first recess is closed;
a wall surface provided on the base, erected toward an outer side of the base from the opening forming surface, and opposed to at least a part of a side surface of the lid member;
a fixing resin that fixes the lid member to the base; and
one or a plurality of protrusions provided in one of the side surface of the lid member and the wall surface and projecting from the one of the side surface of the lid member and the wall surface toward another of the side surface of the lid member and the wall surface, wherein
the opening forming surface is formed from a surface formed on a side surface of the base and extending in a longitudinal axis direction of the insertion section,
the movable member moves within a predetermined moving range in the longitudinal axis direction with respect to the base,
at least one of both ends in the moving range is decided by a position where the movable member is in contact with a restricting section that is a part of a sidewall of the first recess, and
an opening width in the longitudinal axis direction of the second recess is larger than an opening width of the first recess, and a sidewall of the second recess is disposed to be separated in the longitudinal axis direction from the movable member in a contact state with the restricting section.
