<p>A clamp device (C) has: a cylindrical clamp body (1); a grip member (3) that is inserted into an insertion hole (11a) at the top end portion of the cylindrical clamp body (1) and that is capable of extending outwards to grip the inner circumferential surface of an aperture (H) of an article (W); a clamp rod (4) that is engaged with the grip member (3); a forwards / backwards driving mechanism (5) capable of driving the clamp rod (4) forwards and backwards; a seating surface (14) formed at the top end of the cylindrical clamp body (1); a case member (2) supporting the cylindrical clamp body movably forwards and backwards; an elevating/lowering driving mechanism (7) capable of raising and lowering the cylindrical clamp body (1); and a lock mechanism (9) having a cylindrical member (91) into which the cylindrical clamp body (1) is inserted so as to slide freely and capable of locking the outer circumferential surface of the cylindrical clamp body (1) by elastically deforming the cylindrical member (91) so as to reduce its diameter.</p> |
