チ構造。[Claims for Utility Model Registration] A gear 2 is loosely fitted onto the rotating shaft 1, and the rotating shaft 1
A groove 3 carved on the top and a vertical hole 4 bored in the gear 2 on the radial extension of the groove 3 hold the ball 5 having a diameter larger than the length of the vertical hole 4, and The shifter 6, which is slidably fitted on the outer periphery of the gear 2, presses the ball 5 and slides the ball 5 in a releasing state, thereby pushing the ball 5 into the groove 3 and floating the shaft 1.
In the ball clutch structure, an inner groove 14 and an outer groove 15 extend in the axial direction on the inner and outer circumferences of the shifter 6 and the gear 2.
A ball 16 is interposed between these inner grooves 14 and outer grooves 15, and the shifter 6 is fitted to the gear 2 at a distance by the balls 16. A ball clutch structure according to claim 1, further comprising a friction plate (12) provided between the shifter (6) and the fixed wall (11) for applying a braking force to the shifter (6) when the shifter (6) slides toward the side that releases the ball (5). A ball clutch structure according to claim 1, wherein the two types of balls 5 and 16 are provided on substantially the same circumferential surface.
