Abstract
To provide a valve timing adjustment device capable of suppressing generation of noise from an Oldham joint at the time of actuation.SOLUTION: A housing 20 synchronously rotates with a drive shaft 2. A cam gear 30 has an internal gear part 301, and is provided so as to rotate integrally with a driven shaft 3. A planetary rotation body 40 includes an external gear part 43 engaged with the internal gear part 301, and is provided so as to revolve while rotating inside the cam gear 30. An Oldham joint 50 is provided on the opposite side from the driven shaft 3 with respect to the cam gear 30 and the planetary rotation body 40 so as to slide at least with the planetary rotation body 40, and can relatively rotate the housing 20 and the cam gear 30. A plate 70 is provided on the opposite side from the cam gear 30 and the planetary rotation body 40 with respect to the Oldham joint 50. An energization member 80 is provided on the plate 70 side with respect to the Oldham joint 50, and capable of energizing the Oldham joint 50 in the axial direction and the radial direction of the housing 20.SELECTED DRAWING: Figure 1
