Patent ID: 7191881

Claim:
A one-way clutch device comprising: an input side rotating member and an output side rotating member, being arranged coaxially with each other; rollers provided between the rotating members with the one-way clutch device transmitting rotary power from the input side rotating member to the output side rotating member by connecting both members to each other by means of the rollers, in a state where the input side rotating member rotates at a rotational speed above a predetermined rotational speed, and if the input side rotating member relatively rotates in a specific direction with respect to the output side rotating member; and weight members being provided in the input side rotating member, each of the weight members having a weight main body coming into contact with the roller, and an arm part connected to the weight main body and rotatably supported by the input side rotating member; wherein if the input side rotating member rotates at a rotational speed above the predetermined rotational speed, the weight members move the rollers to positions where the rollers allow a connection between the input side rotating member and the output side rotating member.
