Abstract
An injector device is equipped with a casing enabling hydrogen gas to flow in and flow out and a first plunger and a second plunger which are accommodated inside the casing. Further, by a drive unit, the injector device performs a first operation to integrally displace the first plunger and the second plunger and a second operation to displace the first plunger relative to the second plunger. The second plunger has a flow path allowing the hydrogen gas to flow, and the first plunger is disposed to be inserted into the flow path and is displaced relative to the second plunger to open and close the flow path.
