<p><P>PROBLEM TO BE SOLVED: To provide a rotation transmission device capable of clearly maintaining a difference of opening/closing torque between the time when stopping/holding a door at a desirble opening and the time when opening/closing the door without using a difference of friction coefficient due to a difference of contact part like in a current one. <P>SOLUTION: A holder 35, which is formed by coaxially arranging an outer ring 32 on an outer diameter side of a cam ring 31 and forming the periphery of the cam ring 32 with a cam surface 31a and while forming the inner periphery of the outer ring 32 with a cylindrical surface 32a and which holds a pair of rollers 33 freely to be engaged/disengaged in a wedge space 38 formed by the cam surface 31a and the cylindrical surface 32a, is interposed between the cam surface 31a and the cylindrical surface 32a. A rotational resistance giving means for giving rotational resistance between the cam ring 31 and the outer ring 32 is provided, and the outer ring 32 is connected to an automobile body, and the holder 35 is connected to the door. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
