WIPO Patent Application WO/2015/121975

Kind Code:

A1

Abstract:

A valve opening/closing timing control device is provided with an oil reservoir section that makes it possible to efficiently supply oil between a torsion coil spring and a driven-side rotating body. The valve opening/closing timing control device is provided with: a torsion coil spring that is provided to an accommodation chamber that is formed by a front member that is provided to a drive-side rotating body side and a cylindrical space that is provided to the driven-side rotating body so as to face the front member, that is locked to the front member and the driven-side rotating body, and that biases the driven-side rotating body in an advance direction or a retard direction with respect to the drive-side rotating body; and an oil reservoir section that is demarcated and formed by the outer surface of the torsion coil spring that faces the driven-side rotating body and at least one recessed section that is formed in the driven-side rotating body. The recessed section is provided in the radially outward direction from a position that is more radially outward than the inner diameter of the torsion coil spring and more radially inward than the outer diameter of the torsion coil spring.
