Claims

[Scope of utility model registration request]

An output member is rotatably provided on a drive shaft provided with a clutch disk, and a lining plate including a clutch lining and a brake lining is rotatable integrally with the output member, and the clutch lining is brought into pressure contact with the clutch disk by a clutch spring. The lining plate is biased toward the clutch disk so as to be movable in the axial direction of the drive shaft, and is moved in the axial direction of the drive shaft by actuation of an operating lever and presses the brake lining of the lining plate against the clutch disk. In the clutch/brake device, the clutch lining and the brake lining are provided with a pointer indicating the amount of rotation of the operating lever, and the clutch lining and the brake lining have substantially the same thickness. A reference point indicating when the clutch lining comes into sliding contact with the clutch disk, and when the clutch lining comes into sliding contact with the clutch disk when either the clutch lining or the brake lining is worn more than a predetermined amount than the other. 1. A lining wear warning device for a clutch/brake device, characterized in that a biased wear point for displaying the pointer is provided in the vicinity of the pointer.
