Claims

[Scope of utility model registration request]

(1) A cylindrical outer ring that opens upward and has an inner bottom surface with a fitting hole in the center where the inner surface forms a sliding surface with the shaft part, and a part of the shaft body part for fitting with the inner surface of the outer ring. In an overrunning clutch in which a roller is removably positioned at the joint with the shaft and rotational torque is transmitted to the shaft via the roller only when the outer ring rotates in the forward direction, the forward rotation direction C with respect to the inner bottom surface 2 is provided. Approximately 50 degrees upward at
It has a three-dimensional oblique cross-sectional circular shape with multiple lids and bottoms, and has an inclination angle a of up to 50 degrees and an included angle of up to approximately 50 degrees from the radial axis to the positive rotation direction C at the temple edge 5 of the inner bottom surface 2. The hole 6 is located at a position where each hole bottom 7 is located on the peripheral edge 5 of the outer ring inner bottom surface 2 and has an opening 9 facing both the outer ring inner peripheral surface 3 and the inner bottom surface 2 across the peripheral edge 5, and is located on the outer ring peripheral wall. A steel ball 18 formed in the hole 6 and positioned in each hole 6 is made freely movable, and with the steel ball 18 seated on the hole bottom 7, the steel ball 18 is moved from the opening 9 to the inner circumferential surface of the outer ring toward the inner space 4 of the outer ring. 3 and shaft body part 1
