PROBLEM TO BE SOLVED: To provide a structure which does not become load during operation, by preventing vibration after chucking without adding a component. SOLUTION: When the lever shift 30 is moved up by the cam mechanism with the leftward movement of a cam slider 40 and reaches the position of mechanism stop to complete chucking, the boss 31a is placed on a horizontal part 43a3 in a cam groove 43a, and a rib 31a1 provided at the tip of the boss 31a touches the slope 44a1 of a resin spring piece 44 to press up the same. The rib 31a1 presses up the slope 44a1, so that the boss 31a is pressed against a horizontal part 43a3 by the vertically downward pressing force as reaction, and the boss 31a is pressed against the opening edge of a slit 12a in a loader chassis 10 by the horizontally rightward pressing force. Both of the pressing forces prevent the vibration of the cam slider 40 and the lever shift 30. COPYRIGHT: (C)2011,JPO&INPIT
