Abstract:
1. A valve timing control apparatus that controls opening timing and closing timing of one of an intake valve and an exhaust valve of an internal combustion engine, which is opened and closed by a driven-side shaft of the internal combustion engine, through changing of a rotational phase between a driving-side shaft of the internal combustion engine and the driven-side shaft, the valve timing control apparatus comprising: a housing that is rotatable integrally with the driving-side shaft; a vane rotor that is rotatable relative to the housing according to a hydraulic pressure of an advancing chamber formed in the housing and a hydraulic pressure of a retarding chamber formed in the housing, wherein the vane rotor is fixed to the driven-side shaft; a hydraulic pressure control valve that includes: a solenoid that includes: a first tubular portion that extends from the housing toward the solenoid; and a second tubular portion that extends from the solenoid main body or an installation member, to which the solenoid main body is installed, toward the housing and is fitted to the first tubular portion, wherein the second tubular portion cooperates with the first tubular portion to form an oil accumulation chamber that is configured to accumulate at least one of:
