Abstract
A member coupling mechanism includes a first member including a cylindrical member coupling portion including a stepped portion inclined along a circumferential direction from a tip end side of the member coupling portion toward a base end side thereof, a second member configured to be coupled to the member coupling portion, and a coupling member configured to be engaged with the stepped portion while holding an end portion of the second member on a first member side. The coupling member is provided with a rotatable cylindrical protrusion protruding toward an outer or inner peripheral surface of the member coupling portion to be engaged with the stepped portion. When the connecting member is rotated in the circumferential direction, the protrusion moves along the stepped portion while rotating to press the first and second members in an approaching direction to couple them.
