Document Type and Number:
WIPO Patent Application WO/2012/111388
Kind Code:
A1
Abstract:
Provided is a valve opening/closing timing control device that can suppress warping of a driven rotary body, while also simplifying operation processes and reducing the number of parts. The present invention is provided with: a driving rotary body; a driven rotary body; a plurality of partitions, each of which partitions a fluid pressure chamber into a retard chamber and an advance chamber; and a coupling member that couples the driven rotary body and a camshaft. A press-fit part of the coupling member includes a plurality of fitting parts that fits with the inner circumferential surface of a recessed part of the driven rotary body, and is formed such that the center line of at least one fitting part in the radial direction does not overlap with the partitions in the radial direction.
