Abstract:
To suppress the worsening of slidability between a driven rotation body and a driving rotation body.SOLUTION: A valve timing adjustment device 100 is fastened to an end in an axial direction AD of one of a driving shaft 210 and a driven shaft 220 to adjust valve timing for a valve which changes a rotation phase of the driven shaft relative to the driving shaft to drive the opening/closing with the driven shaft. The valve timing adjustment device includes a first rotation body 30 to be rotated in conjunction with one shaft, and a second rotation body 10 to be rotated in conjunction with the other shaft. The first rotation body has: fastened parts 31, 31a fastened to one shaft with a bolt 63 arranged in a through-hole 36; slide parts 32, 32a for sliding with the second rotation body on slide surfaces SS, SSa along a direction intersecting with the axial direction; and a bearing part 33 having an outer peripheral face 37 continuing from the outer edges of the slide parts, formed on the opposite side to one shaft side in the axial direction, opposed to an inner peripheral face 19 of the second rotation body, and bearing the second rotation body, the fastened parts being protruded to the one shaft side in the axial direction further than the slide parts and the bearing part.SELECTED DRAWING: Figure 3
