摘要： PROBLEM TO BE SOLVED: To provide a centrifugal clutch that is excellent in power transfer performance, regardless of its simple arrangement with a small number of part items and that resists the wear of a clutch boss and a clutch shoe.
SOLUTION: The centrifugal clutch includes a driven drum, a clutch boss 3 rotating about the axis C of a drum cylinder, a clutch shoe 4, and a biasing member 5 for elastically biasing the clutch shoe 4 toward the clutch boss. A fulcrum projection 21 serving as the oscillation fulcrum 20 of the clutch shoe 4 and a retaining projection 22 disposed in a position in front in the rotation direction R of the fulcrum projection 21 are provided on the outer peripheral surface of the clutch boss 3. A fulcrum groove 23 facing the fulcrum projection 21 of the clutch boss 3 slidable in the rotation direction and a retaining groove 24 facing the retaining projection 22 of the clutch boss 3 freely movable toward and away from it are formed on the inner peripheral surface of the clutch shoe 4. The forward outer peripheral surface of the retaining projection 22 in the rotation direction is formed as a projecting curved surface 25, and the forward inner peripheral surface of the retaining groove 24 in the rotation direction is formed as a recessed curved surface 26 facing the projecting curved surface 25 of the retaining projection 22.

摘要： PROBLEM TO BE SOLVED: To provide a fluidic power control device that suppresses rotational resistance during low rotation of a rotary shaft and can rapidly perform projecting/retracting operation of a projecting/retracting member.SOLUTION: A fluidic power control device 5 controls power from a rotary shaft 41 rotatably supported at the lower end of a rear leg section 21 via fluid with respect to a drum 55 fixed on the rear leg section. The fluidic power control device 5 includes an inner rotor 51 rotating integrally with the rotary shaft 41, an outer rotor 53 for sealing the inner rotor 51 while providing a first space 52, the drum 55 for sealing the outer rotor 53 while providing a second space 54, projecting/retracting members 56 that engage with the outer rotor 53 and rotate integrally with it when projecting due to the centrifugal force of the inner rotor 51, energizing springs 57 that energize the projecting/retracting members 56 so as to retract, make the projecting/retracting members 56 project when the centrifugal force of the inner rotor 51 is larger than the energizing force, and make the projecting/retracting members 56 retract when the centrifugal force is smaller than the energizing force, and a dilatant fluid R2 filled in the second space 54.
