<P>PROBLEM TO BE SOLVED: To provide a cartridge tank cap for an oilstove in which a torque controlling mechanism is built in between the cap body and a handle so that an idle running of the cap can occurs and a sound can be generated when an excess torque is applied. <P>SOLUTION: The torque controlling mechanism is built in between the cap body 6 composing the cap and the handle 21 and the mechanism is composed by engaging a pair of ratchets having teeth sloping in a specific direction of the rotation on opposed surface. Teeth of one ratchet are provided on the handle and teeth of the other ratchet are provided on an elastic material composed of a vertical material and a horizontal material on a hollow disk 31 and the hollow disk is fixed on the flange of the cap body attachably and detachably and is sandwiched by the handle. When an excess torque acts on the teeth faces of the ratchets at rotating the cap, the elastic material is deformed to disconnect the engagement of the teeth and continuous sounds are generated at the idle running. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
