    • In friction engagement device having forward clutch 5 and clutch operation pack 6 controlling engagement/disengagement operation of the forward clutch 5, the clutch operation pack 6 has hydraulic piston 61, engagement pressure piston chamber 62, snap ring 64, diaphragm spring 65 and ball lock mechanism BL. The diaphragm spring 65 provides biasing engagement force to the forward clutch 5 at a clutch side of the hydraulic piston 61. The ball lock mechanism BL restrains movement, in a disengagement direction, of the hydraulic piston 61 at a position where the forward clutch 5 is in an engagement state by the biasing engagement force by exerting ON pressure on the engagement pressure piston chamber 62, and after restraining the movement of the hydraulic piston 61, maintains the restraint of the disengagement direction movement of the hydraulic piston 61 even when the ON pressure of the engagement pressure piston chamber 62 is drawn.
    • 在具有前进离合器5和离合器操作组6的摩擦接合装置中,离合器操作组6具有液压活塞61,接合压力活塞室62,卡环64,隔膜弹簧65和球锁 机制BL。 隔膜弹簧65在液压活塞61的离合器侧向前进离合器5提供偏压接合力。球锁定机构BL限制液压活塞61沿分离方向在前进离合器5为 在通过对接合压力活塞室62施加ON压力的接合状态下,并且在限制了液压活塞61的运动之后,即使在ON压力下也保持液压活塞61的分离方向运动的约束 的啮合压力活塞室62被拉出。
