Title:
VALVE TIMING ADJUSTMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/179322
Kind Code:
A1
Abstract:
A driving rotating body (10) has driving-side stopper walls (62a, 62r). A driven rotating body (20) has driven-side stopper walls (64a, 64r). The driven rotating body rotates relative to the driving rotating body, and the phase of rotation of the driven rotating body relative to the rotation of the driving rotating body changes. The driven rotating body causes the driven-side stopper walls to come into contact with the driving-side stopper walls in the directions (Da, Dr) of relative rotation, and as a result, a change in the phase of rotation is restricted. A planetary gear (50) performs a planetary motion while meshing with both the driving rotating body and the driven rotating body to change the phase of rotation. The driving rotating body has a gear member (11), a cover member (13), and a fastening member (15). The gear member forms the driving-side stopper walls and meshes with the planetary gear (50). The cover member covers, together with the gear member, an accommodation space (14) in which the driven rotating body and the planetary gear are accommodated. The fastening member axially fastens the gear member and the cover member.
