がある。 As described above, the present invention consists of a metal mounting body provided with a threaded portion that is screwed into a filler neck of a gasoline tank, a synthetic resin dial cover that is rotatably engaged with the mounting body, and a rotating It consists of an intermediate moving member made of synthetic resin that is housed within the mounting body so as to be movable only in the axial direction while its rotation is regulated by a restraining means, and an inclined surface is provided on the lower surface of the dial lid and the upper surface of the intermediate moving member. A toothed part consisting of a part and a locking part is provided to engage with each other, a spring foot part is provided at the lower part of the intermediate moving member to engage with the seat part of the attachment body, and the dial cover is closed. During operation, the inclined surfaces of the toothed portions that face each other engage, and when a certain amount of torque is applied, the intermediate moving member moves in the axial direction via the spring foot, causing the toothed portions to engage. Since it is constructed so that it can be unraveled, the torque regulation structure can be easily assembled between the dial lid and the dial cover by inserting an intermediate moving member made of synthetic resin into the mounting main body.
If the torque regulating structure breaks down, it can be easily and quickly repaired by replacing the parts.
