The connection part includes a first connection member 32; and a second connection member 34 disposed to face the first connection member. The first connection member and the second connection member are attracted to each other. The first connection member is fixed to the arm unit support part, and the second connection member is mounted on the arm unit. The second connection member is disposed to be movable around the first connection member. A surface shape of a part of the first connection member facing the second connection member is a convex shape. The surface shape of the part of the second connection member facing the first connection member is a concave shape corresponding to the convex shape of the first connection member.</p> |
