<p>This invention relates to a clutch having a rotating cam mounted fixedly on a driving shaft, and aims at eliminating shocks when the driving shaft and a driven shaft are connected or disconnected. The clutch is provided with a fixed cam having a fixed surface opposed to a surface of a rotating cam, a slider in contact with both of these cams and movable between first and second positions along an arm member, and an arm member mounted fixedly on the driven shaft and adapted to transmit the rotation of the slider to the driven shaft. The rotating surface includes a portion where the rotation is transmitted to the slider in the first position, a portion where the rotation is not transmitted thereto in the second position, and passages connecting these two portions for the slider to move between them and having a predetermined inclination with respect to the rotational direction. The fixed surface includes a portion where the rotation of the slider is permitted in the first position, a portion where the rotation of the slider is stopped in the second position, and passages connecting these two portions for the slider to move between them and having a predetermined inclination with respect to the rotational direction.</p> |
