Abstract:
1. A cap device that opens and closes a tank opening, the cap device comprising: a closer that closes the tank opening; a handle mechanism that rotates the closer about a rotation axis of the closer and includes a handle and a cover that holds the handle; a torque plate interposed between the closer and the handle mechanism, the torque plate transmitting a rotational torque applied to the handle mechanism in a closing direction and an opening direction to the closer within a preset level; a plate attachment mechanism that attaches the torque plate to the closer, the plate attachment mechanism being configured such that parts of the torque plate are elastically deformed by an external force applied to the handle mechanism and thereby detaching the torque plate from the closer; and a handle mechanism attachment mechanism that holds the handle mechanism on an outer circumference of the torque plate in a rotatable manner, wherein the handle mechanism attachment mechanism is arranged about the rotation axis of the closer and outside the plate attachment mechanism, wherein the torque plate has first springs and second springs that hold the torque plate between an upper wall of the cover and an upper portion of the closer, wherein the first springs and the second springs include an arm formed as a cantilever that is elastically deformed in an axial direction of the closer, wherein the torque plate has a fragile element formed along an inner circumference of the torque plate, and wherein the fragile element includes fragile grooves on the torque plate.
