A contact member(20) has a contact portion(21) contacted with an upper surface of a turntable(13). A rotation member(30) is disposed to elevate the contact member(20). The rotation member(30) is connected to an external motor(M), and rotated by the external motor(M). A connection member(40) has one end portion coupled with the contact member and the other end portion coupled with the rotation member. The connection member(40) has a bellows part(41) provided between both end portions thereof.
