Abstract: Provided is a valve device and a shock absorber that can prevent them from being in a failure state at the normal time and can freely set a passive valve even when both pressure control and passage opening/closing are performed by a solenoid valve. For this reason, the valve device includes a first passage and a second passage connected downstream of the pressure introducing passage, a solenoid valve that opens the first passage to control the upstream pressure and closes the second passage when energized, and that closes the first passage and opens the second passage when not energized, and a passive valve provided downstream of the solenoid valve in the second passage.

Abstract: To provide a solenoid, a solenoid valve, and a damper in which when the amount of current supplied to the solenoid is small, the thrust of the solenoid to bias an object in one direction can be made small, and at the same time, even when the solenoid is not energized, the object can be biased in the same direction as that of the thrust. The solenoid includes a coil, a first movable iron core and a second movable iron core that are attracted in a direction away from each other by energizing the coil, a coil spring that biases the first movable iron core toward the second movable iron core, and a leaf spring that restricts the approach of the first movable iron core and the second movable iron core.
