Document Type and Number:
Japanese Patent JP7030038
Kind Code:
B2
Abstract:
To prevent generation of friction between an outer ring and an engagement element when a rotation transmission device idles at a high speed.SOLUTION: An inner member 3 and an outer ring 2 are coaxially disposed inside and outside of an inner ring 1. An engagement element 4 is disposed in a manner of being rotated integrally with the inner ring 1, and radially movable between a neutral position and an engagement position. The engagement element 4 cannot be kept into contact with the outer ring 2 at the neutral position, and is engaged with an engagement recessed portion 2a of the outer ring 2 in a circumferential direction at the engagement position. A cam surface of the inner member 3 converts relative rotation with the inner ring 1, into radial movement of the engagement element 4. The engagement element 4 is energized to the neutral position by an elastic member 5. The rotation transmission device includes a neutral spring 6 elastically deformed by the relative rotation, an armature 7 locked to one of the inner ring 1 and the inner member 3, an electromagnet 8 axially opposed to the armature 7, a frictional surface portion 9 locked to the outer ring 2 and axially opposed to the armature 7, and a separating spring 10 pressing the armature 7 in a direction to separate from the frictional surface portion 9.SELECTED DRAWING: Figure 1
