发明名称 Bending angle adjustment mechanism for endoscope
摘要 A bending angle adjustment mechanism includes a rod member that is disposed along a traveling path of a long member that is connected to a bending portion that is bendable and has a threaded portion formed thereon, an adjustment piece that is disposed in a predetermined position of the rod member by being engaged with the threaded portion, and restricts movement of the long member, a head portion that is provided at an end portion of the rod member to rotate the rod member, a support member that is provided at both ends of the rod member and rotatably supports the rod member, and a convex portion that protrudes to be higher than a lower edge position of an outer circumferential edge portion of the head portion while keeping the head portion of the rod member which is supported by the support member, in a rotatable state.

主权项 1. A bending angle adjustment mechanism for an endoscope, comprising: a rod member that is disposed along a traveling path of a long member that is connected to a bending portion that is bendable, and has a threaded portion formed thereon; an adjustment piece that is disposed in a predetermined position of the rod member by being engaged with the threaded portion, and restricts movement of the long member; a guide member that is provided along the rod member and guides movement of the adjustment piece in an axial direction of the rod member; a head portion that is provided at an end portion of the rod member to rotate the rod member; a support member that is provided at both ends of the rod member and rotatably supports the rod member; and a convex portion that is provided in the guide member to protrude to be higher than a lower edge position of an outer circumferential edge portion of the head portion, is formed to have elasticity so that the head portion is allowed to ride over the convex portion when the rod member is inserted into the support member along the axial direction of the rod member, and prevents the rod member from falling off from the support member while keeping the head portion of the rod member which is supported by the support member, in a rotatable state.
