ABSTRACT:
A chuck device has a pair of grippers pivotally supported in a recess defined in an end of a body for angular movement about a predetermined angle, a joint member connected to a piston reciprocally movably disposed in a cylinder chamber defined in the body, and a pair of rollers engaging respectively in grooves in the grippers and angularly movably mounted on the joint member. Linear movement of the piston can be transmitted as angular movement to the grippers through the rollers while the rollers are angularly moving with respect to the joint member. A cover is mounted on the end of the body in closing relation to the recess.
