1. An attaching and detaching apparatus comprising:
a first mounting plate to which a first mounting object is to be mounted;
a second mounting plate to which a second mounting object is to be mounted, the second mounting plate being disposed at a distance from the first mounting plate;
a magnet to separably connect the first mounting plate and the second mounting plate to each other; and
a connecting member disposed between the first mounting plate and the second mounting plate, the connecting member being formed separately from the first mounting plate and the second mounting plate, wherein
the connecting member includes a first connecting member fixed to the first mounting plate and a second connecting member fixed to the second mounting plate,
at least one protrusion is formed on a first one of the first connecting member and the second connecting member, the protrusion projects toward a second one of the first connecting member and the second connecting member,
at least one hole into which the protrusion fits is formed on the second one of the first connecting member and the second connecting member,
the protrusion has a first contact surface in a shape symmetric about a central axis of the protrusion,
an inner surface of the hole is a second contact surface in a shape symmetric about a central axis of the hole, and
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, and wherein the attaching and detaching apparatus further comprising:
a first bolt to fix the second connecting member to the second mounting plate, wherein
a first bolt hole for accommodating the first bolt is formed in the second connecting member,
a first through hole for allowing the first bolt to pass therethrough is formed in the second mounting plate, and
the first hole is larger than a shaft diameter of the first bolt.
