PROBLEM TO BE SOLVED: To provide a braking plate assembly for a drag mechanism in which a drag force can be improved and a weight can be reduced simultaneously.SOLUTION: A first braking plate assembly 51 and a fourth braking plate assembly 54 include a first plate element 61 and a second plate element 62, respectively. A first joining surface 61a of the first plate element 61 and a second joining surface 62a of the second plate element 62 are connected with each other. Specifically, the first braking plate assembly 51 and the fourth braking plate assembly 54 function as the braking plate of a single body, respectively. Also, the wear resistance of the second plate element 62 is higher than that of the first plate element 61, so that a lining material can be brought into frictional contact with the second plate element 62. |
