Problems solved by technology

[0004] In the cap using a key, if the cylinder lock is unlocked with the key after tightening the cap, the protrusion on the cylinder lock side (driver side) will be separated from the groove on the male thread side (driven side), so it cannot be tightened. Loosen (for example, refer to Patent Document 2)
[0005] However, in the fuel tank cap of Patent Document 1, since the engine can be started without closing the cap, there is a problem that the engine is started without closing the cap inadvertently, and then the running is started.
[0006] In the cap of Patent Document 2, when the cap is opened to place or hang the cap, there is a problem that sand and muddy water adhere to the external thread of the cap

Abstract

A lockable cap for a fuel tank. The cap (11, 11B, 11C, 11D, 11E) is provided with a ring stopper (26) for making connection and disconnection between an outer cap (21) and a housing cap (23). The ring stopper releases connection between the housing cap and the outer cap upon completion of closing operation of a fuel filling opening (14), and this ensures that a user does not inadvertently forget to close the cap.

Description

technical field [0001] The present invention relates to a lock cap for opening and closing a fuel supply port of a fuel tank. Background technique [0002] In the lock cap, the threaded portion of the cap is rotatable by a key, and the key is released to open the fuel supply port of the fuel tank. For example, it is known to lock the cover with a key to start the engine to make it idling (unopenable), or to lock it without using a key to make it idling (unopenable). [0003] Among the caps that do not use keys, for example, as disclosed in Patent Document 1, there is a known fuel tank cap: when the cap is tightened, if it is rotated clockwise, the parts of the cylinder lock in the cap will rotate to the locked position, and the cap will be locked. Locking, so the key can be used in the oil supply, and various electric accessories can be operated at the same time as the oil supply. [0004] In the cap using a key, if the cylinder lock is unlocked with the key after tighteni...
