    摘要： A power-assisted bicycle is provided with a one-way clutch that can also be used as a torque detection apparatus. The one-way clutch has a tooth part (112) mounted on a driven means and a piece part (100) mounted slidably yet non-rotatably on a drive shaft (4). The tooth part has a first engagement face (121) formed with a plurality of teeth (114) and the piece part has a second engagement face (110) formed with a plurality of pieces (102). The first engagement face and the second engagement face are disposed facing each other generally perpendicularly to the axial direction. A disc spring (124) is disposed on the rear face of the piece part. As the piece part rotates in the direction of running forward, the piece is engaged with a sharply sloping face of the tooth to engage with the tooth and the angle of the piece with respect to the second engagement face increases, whereby the piece slides so as to increase the distance from the tooth part in resistance to the disc spring. As the piece rotates in the opposite direction, the piece abuts with the gently sloping face of the tooth and the angle of the piece with respect to the second engagement face is made smaller to decrease the distance from the tooth part by means of the elasticity of the disc spring.

    摘要： A power-assisted bicycle is provided with a torque detection mechanism system that is simple in structure, saves space therefor, and is lightweight. A one-way clutch (72) for transmitting only rotation of the drive shaft (4) to the sprocket (70) in the direction in which the bicycle proceeds is disposed inside a hollow cylindrical portion (82) of the sprocket (70). On the sprocket face opposite thereto, a bearing (74) is engaged in an outer periphery of the cylindrical portion (82), and an elastic disc spring (76) holds the sprocket (70) with the aid of the bearing. The disc spring (76) is fixed to the bicycle body and a strain gauge (80) for detecting a stress deformation of the disc spring (76) is mounted on the surface thereof. As the drive shaft (4) is rotated by the aid of the pedaling torque, the one-way clutch (72) exerts an axially pressing force onto the sprocket (70) to deform the disc spring (76) and the strain gauge (80) detects the stress deformation of the disc spring (76), that is, a physical amount associated with the pedaling torque.
