PROBLEM TO BE SOLVED: To improve operation performance of a brake mechanism by making constant a return size of a piston obtained when braking is released.SOLUTION: A brake mechanism 33 includes: a projection region 40 which is provided projecting radially inward from an inner-diameter side of a piston 37 while apart from a partition wall 15A of a brake case 15 in a right and left direction and facing the partition wall 15A; a pin hole 41 provided penetrating the projection region 40 in the right and left direction; a pin member 42 which is fitted in the pin hole 41 movably in the right and left direction with both end sides projected from the pin hole 41 in the right and left direction, and has one-end part 42A in the right and left direction capable of coming into contact with the partition wall 15A when the piston 37 is at a non-braking position; and a stopper member 43 which is provided apart from other-end part 42B in the right and left direction of the pin member 42 with a separation size G large enough for each rotary disk 35 and each non-rotary disk 36 to separate, and allows the pin member 42 to move within a range of the separation size G.SELECTED DRAWING: Figure 4
【課題】 制動を解除したときのピストンの戻り寸法を一定にすることにより、ブレーキ機構の動作性能を向上する。【解決手段】 ブレーキ機構３３は、ブレーキケース１５の隔壁１５Ａと左，右方向に離間すると共に隔壁１５Ａと対面した状態でピストン３７の内径側から径方向の内向きに突出して設けられた突出部位４０と、突出部位４０に左，右方向に貫通して設けられたピン孔４１と、ピン孔４１から両端側が左，右方向の突出した状態でピン孔４１に左，右方向に移動可能に挿嵌されピストン３７が非制動位置にあるとき左，右方向の一端部４２Ａが隔壁１５Ａに当接可能なピン部材４２と、各回転ディスク３５と各非回転ディスク３６が離間することができる離間寸法Ｇをもってピン部材４２の左，右方向の他端部４２Ｂと離間して設けられ、離間寸法Ｇの範囲でピン部材４２の移動を許すストッパ部材４３とを含んで構成する。【選択図】図４
