Title:
DECELERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/044812
Kind Code:
A1
Abstract:
This deceleration device is provided with: an input-side rotating member having an input plate in which a first ball-engaging groove is formed; an output-side rotating member having an output plate in which a second ball-engaging groove is formed; a plurality of balls that engage in the ball-engaging grooves of the input plate and the output plate, which oppose each other in an axial direction; and a holder having a plurality of pockets for holding the balls so as to enable the balls to move in a radial direction. The holder is incapable of rotating relative to the rotating shaft, and rotation of the input-side rotating member is decelerated and transmitted to the output-side rotating member via the balls engaged in the ball-engaging grooves. Provided to both axial-end sides of the pockets in the holder are reduced-width parts that allow the balls to move radially by engaging in the second ball-engaging groove, and that restrain the balls from falling out.
