Abstract

Provided is a valve opening closing timing control device wherein a front member is attached using multiple countersunk head screws and with which the attachment between the front member and the driving rotating body does not easily loosen; also provided is a method for attaching the front member. This valve opening closing timing control device is equipped with: a driving rotating body that rotates synchronously with a crankshaft; a following rotating body that rotates integrally with a cam shaft on the same axis as the driving rotating body; a phase control mechanism that controls the changing of the relative rotational phases of the driving rotating body and the following rotating body; a torsion coil spring that is engaged by a front member of the driving rotating body and by the following driving body and biases the following rotating body in the advance direction or the retarded direction with respect to the driving rotating body. The front member is equipped with multiple bearing surfaces provided so as to be attached with countersunk head screws and an engaging part that engages the end of the torsion coil spring with the torsion coil spring in a twisted state. The engaging part is equipped with a mounting part for a manipulating tool with which the end of the torsion coil spring is moved in the direction in which the torsion strength of the torsion coil spring increases.
