Abstract:
This speed-changing device (10A) is provided with: an umbrella-shaped body pair (11, 15) provided with a fixed umbrella-shaped body (13, 17) that is fixed in the axial direction and a movable umbrella-shaped body (14, 18) that is movable in the axial direction relative to the fixed umbrella-shaped body (13, 17); an endless member (19) that is wound on the umbrella-shaped body pair (11, 15) and is sandwiched between the fixed umbrella-shaped body (13, 17) and the movable umbrella-shaped body (14, 18); and a power device (31, 41) that moves the movable umbrella-shaped body (14, 18) in the axial direction. The power device (31, 41) performs pushing/pulling control in which a force in a pushing direction for making the movable umbrella-shaped body (14, 18) approach the fixed umbrella-shaped body (13, 17) and a force in a pulling direction for moving the movable umbrella-shaped body (14, 18) away from the fixed umbrella-shaped body (13, 17), are alternately applied at a predetermined interval.
