PROBLEM TO BE SOLVED: To prevent damage to a plate-like material by securing smooth vertical motion of a bolt to exhibit primary function of a shock absorbing member even if the bolt and a screw hole are shifted in a plate-like material transport apparatus in which the tip of a bolt loosely fitted in a bolt loose fit hole to move up and down is engaged with the screw hole, a suction pad having the screw hole is supported in suspended state through the bolt and the shock absorbing member loosely fitted to the outer peripheral side of the bolt, and in the suction pad, the shock in holding and releasing the plate-like material is softened. SOLUTION: A clearance regulating member 21 is composed of a sliding cylinder part 23 slidably surrounding the periphery of the bolt, a taper part 24 formed like a skirt from one inner peripheral end part 23a of the sliding cylinder part 23 toward the outer peripheral end part 24a with the inner peripheral end part 23a entering between a bolt loose fitting hole 10 and the bolt 18 to thereby restrain looseness of the bolt loose fit hole 10 and the bolt 18, and a pressed part 25 pressed in contact with the end of a compression spring 22 extending from the other inner peripheral end part 23b of the sliding cylinder part 23 to the skirt part of the tapered part 24. The constructed clearance regulating member 21 is interposed in the clearance between the bolt loose fit hole 19 and the bolt 18. COPYRIGHT: (C)2004,JPO
