Abstract
An insertion apparatus includes: a bend preventing member having a first opening and a second opening; an exterior member connected to the bend preventing member in a state where the exterior member abuts against a second surface side, and a projection which is formed on the second surface circumferentially in a protruding manner toward the exterior member, the projection being elastically deformable such that the projection is inclined in an outside direction of the bend preventing member by making the projection abut against the exterior member.
Claims11
An insertion apparatus comprising:
- a tubular member formed in a tapered shape, the tubular member having a through hole with a first opening formed at one end of the through hole and a second opening formed at another end of the through hole, the second opening having a larger diameter than the first opening, and the tubular member having an outer tapered peripheral surface connecting a first surface having the first opening and a second surface having the second opening;
- an exterior member connected to the tubular member in a state where the exterior member abuts against a projection on the second surface of the tubular member;
- and
- the projection circumferentially formed on the second surface to project toward the exterior member, the projection being elastically deformable such that the projection is inclined radially outward from a central longitudinal axis of the tubular member when the projection is made to abut against the exterior member.

An insertion apparatus comprising:
- a tubular member formed in a tapered shape, the tubular member having a through hole with a first opening formed at one end of the through hole and a second opening formed at another end of the through hole, the second opening and having a larger diameter than the first opening, and the tubular member having an outer tapered peripheral surface connecting a first surface having the first opening and a second surface having the second opening;
- an exterior member connected to the tubular member in a state where the exterior member abuts against a ring-shaped projection on the second surface of the tubular member;
- and
- the ring-shaped projection circumferentially formed on the second surface to project toward the exterior member, the projection formed such that a distance between an inner diameter and an outer diameter of the projection decreases as the projection extends away from the second surface, and the projection being elastically deformable such that the projection is inclined radially outward from a central longitudinal axis of the tubular member when the projection is made to abut against the exterior member.

A connection structure for connecting an exterior member and a tubular member, the connection structure comprising:
- the tubular member formed in a tapered shape, the tubular member having a through hole with a first opening formed at one end of the through hole and a second opening formed at another end of the through hole, the second opening having a larger diameter than the first opening, and the tubular member having an outer tapered peripheral surface connecting a first surface having the first opening and a second surface having the second opening and is formed in a tapered shape;
- the exterior member connected to the tubular member in a state where the exterior member abuts against a ring-shaped projection on the second surface of the tubular member;
- and
- the ring-shaped projection circumferentially formed on the second surface to project toward the exterior member, the projection formed such that a distance between an inner diameter and an outer diameter of the projection decreases as the projection extends away from the second surface, and the projection being elastically deformable such that the projection is inclined radially outward from a central longitudinal axis of the tubular member when the projection is made to abut against the exterior member.
