Claims

[Claims for Utility Model Registration] (1) A rod-shaped operating member that is movable in the longitudinal direction, and an attached member that urges the operating member from a predetermined position in a direction opposite to the direction of movement of the operating member. , and a locking member that holds the operating member in another predetermined position against the biasing force of the biasing member, and the operating member has a concave surface and a stepped portion surrounding the concave surface on the circumferential surface thereof. A concave surface of the concave operation portion includes a first protruding step having an inclined surface inclined obliquely in the moving direction of the operating member and one end of which is connected to the stepped portion; A V-shaped protrusion step is formed, the second protrusion step having an inclined surface that extends obliquely upward in the biasing direction of the biasing member from the inclined end portion of the protrusion step and whose terminal end is not continuous with the step portion; The concave surface of the V-shaped protrusion section above the second protrusion section has an escape groove extending obliquely upward along the second protrusion section, past the end of the second protrusion section, and in the moving direction of the operating member. A positioning mechanism characterized in that the locking member is provided with a pawl that locks the V-shaped protrusion step and the escape groove. (2) The positioning mechanism according to claim 1, wherein the V-shaped protrusion step is arranged in a plurality of steps in the longitudinal axis direction of the operating member.
