ABSTRACT:
Disclosed herein is a mechanism for locking the angular movement of a suction pad. The mechanism comprises a tubular body fitted to a root part of the suction pad and having a flange; a cover member attached to a moving assembly for displacing the suction pad; a first bush having a slide resistance lower than the tubular body and fitted to the flange of the tubular body; and a second bush having a slide resistance lower than the cover member and fitted to the inside of the cover member. The first bush and second bush are engaged with each other in such a manner that alternating concavities and convexities of the first bush are meshed with alternating convexities and concavities of the second bush, respectively, whereby the displacement of the suction pad in its axial direction is guided, and the angular movement of the suction pad is prevented.
