Claims

[Scope of utility model registration request]

The inner diameter surface of the outer ring and the outer diameter surface of the output shaft inserted inside the outer ring are made into cylindrical surfaces, and the output shaft and the input shaft arranged coaxially with this are engaged with a clearance in the rotational direction, and the rotation thereof is The input shaft and the output shaft are connected by a torque setting elastic member that maintains the directional clearance at a neutral position, and one of the two cages with different diameters installed between the cylindrical surface of the outer ring and the cylindrical surface of the output shaft is used. The diameter side retainer is connected to the input shaft, the small diameter side retainer is connected to the output shaft, the outer end is inserted into the pocket formed on the large diameter side retainer, and the inner end is inserted into the pocket formed on the small diameter side retainer. A cam surface that can engage with both the cylindrical surfaces is formed on the outer diameter side and the inner diameter side of the sprag with the end inserted, and elasticity of a pair of elastic members arranged on both sides of the sprag is imparted to the sprag. In this clutch, the cam surface is held at a neutral position where the cam surface does not engage with both cylindrical surfaces. A clutch characterized by being pressed into contact with the cylindrical surface of the output shaft.
