Abstract

An attaching and detaching apparatus includes a main mounting plate to which a main mounting object is to be mounted, an attachment mounting plate to which an attachment mounting object is to be mounted, and a connecting member between the main mounting plate and the attachment mounting plate. A protrusion projecting toward the connecting member is formed on the main mounting plate. A hole into which the protrusion fits is formed on the connecting member. A first contact surface in the shape of a surface of revolution is formed on the protrusion. A second contact surface in the shape of a surface of revolution is formed on the inner surface of the hole. The first contact surface and the second contact surface are in contact with each other with the central axis of the protrusion coinciding with the central axis of the hole.
