Claims

[Claims for Utility Model Registration] A mechanism for attaching and detaching a power transmission shaft consisting of a first rotating shaft connected to a driving member and a second rotating shaft provided to a driven member, A cylindrical shaft-shaped first attachment/detachment part provided at the shaft end and having spline teeth formed on the inner periphery; and a convex shaft-shaped second attachment/detachment part provided at the shaft end of the second rotating shaft and having spline teeth formed on the outer periphery. a removable part; a support member fixed in position that rotatably supports the first removable part in a penetrating state in a substantially horizontal position; and a pin which is housed in the hole so as to be rotatable around an axis along the radial direction and whose inner end protrudes substantially flush with the spline teeth of the first detachable part. A power transmission shaft attachment/detachment mechanism characterized by:
