PURPOSE:To provide a buckle draw device sufficiently ensuring the draw quantity of a buckle and also eliminating a broad arrangement space with smallness realized. CONSTITUTION:A buckle 22 is connected to the large diameter part 34 of a pulley 32 via a wire 26, and a piston 44 is connected to the small diameter part 36 of the pulley 32 via a wire 38. Consequently, the movement stroke of the piston 44 is expandedly transmitted, and the movement quantity of the buckle 22 is ensured to surely draw the buckle 22 even the movement stroke of the piston 44 is small. As a result, the overall length of a cylinder 46 can be shortened, and a device is miniturized to eliminate a broad arrangement space to also eliminate the worsening of assembly. |
