PROBLEM TO BE SOLVED: To provide a clutch cutoff device capable of detecting the worn state of a clutch disk while shortening the axial dimension of the device and further with excellent workability in the maintenance and inspection of a sensor or the like used for detecting the wear. SOLUTION: The worn state of the clutch disk 9 is detected by providing a wear detecting mechanism M with a detecting arm 13 abutting on a displacement member (a movable part) linearly moving in an axial direction following the wear of the clutch disk 9, and swinging in response to the displacement of the displacement member 17, and a rotational displacement sensor 10 connected to the swing center of the detecting arm 13 and mounted to the outer part of a cylinder housing 1.
