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; and a support member fixed at a fixed position that rotatably supports the first removable part in a penetrating state in a substantially horizontal position, and the support member is formed in an annular shape having a groove along the circumferential direction on the outer periphery. , and the support member is immovably attached to a fixed portion installed at an arbitrary position via two attachment pieces that are slidably fitted into the groove.
