<p>PROBLEM TO BE SOLVED: To detect the engaged state of a clutch and improve the resolution of a clutch stroke sensor by providing a switching clutch consisting of a first piston, a second piston and a cylinder body, and providing the clutch stroke sensor for detecting the operating position of the first piston. SOLUTION: In order to smoothen the connection operation of a clutch, it is necessary to control the connection speed (to control the opening and closing of solenoid valves 46a, 46b) according to the engagement state of the clutch. The engagement state of the clutch can be grasped by a clutch stroke sensor 6 for detecting the operating position of the first piston 62 of a switching cylinder 6. The operating range of the first piston 62 extends from the non- operating position to the position where it makes contact with the right end wall 611 of a cylinder body 61, and it is regularly constant. Accordingly, since the operating range is never extended even if the clutch facing of a clutch driven plate 21 is worn, the resolution of the clutch stroke sensor 66 can be improved.</p> |
