PURPOSE: To put a pair of sliders to get closer to/apart from each other simultaneously for an equal distance for holding an article by jaws provided on the sliders without position deflection by installing both end parts of a link in a synchronism device on the respective sliders to be capable of oscillation. CONSTITUTION: In picking up a first connector C' by a pickup head 18, a shaft is lowered by a robot in accordance with a program, and jaws 98 provided on a pair of sliders 82 are positioned on both sides of a connector C'. Next, a piston cylinder unit 62 is actuated, carriers 76 and the jaws 98 are closed, and the connector C' is held by the jaws 98. At this time, a pair of the carriers 76 and the jaws 98 move to each other for an equal distance because a pin 88 on an axis Z is at a center of a link 92, and as pivot pins 96 of the link 92 are at an equal distance from the pin 88. As a result, a center of the connector C' held by the jaws 98 can be constantly set to correctly coincide with the axis Z. |
