Abstract
A solenoid valve device includes a solenoid valve that has a solenoid portion, a valve element that drivingly slides using electromagnetic force generated by the solenoid portion and regulates and outputs fluid pressure supplied from a fluid pressure source, a spring that biases the valve element in the sliding direction, and a spring chamber that accommodates the spring; an accumulating portion that accumulates operation fluid; an intake check valve that permits the flow of operation fluid from the accumulating portion to the spring chamber; and a discharge check valve that permits the flow of operation fluid from the spring chamber to an operation destination different from the accumulating portion.
