<p>A structure in which friction plates (39, 40a, 40b) are prevented from interfering with other members therearound or with the body of a driver and that facilitates, in assembly work, insertion of a tension rod (17a) into a round hole (47) and longitudinally elongated holes (18a, 18b) formed in the frictional plates (39, 40a, 40b). The friction plates (39, 40a, 40b) are disposed between the inner surface of a support plate (22a) forming a fixed side bracket (15a) and both side surfaces of a displacement side bracket (36). Further, each friction plate (39, 40a, 40b) is formed as a left and right pair, and end edges of each pair are connected together by a connection part (45, 46a, 46b). Consequently, the holes (47, 18a, 18b) through which the tensile rod (17a) is inserted can be easily aligned with each other.</p> |
