<P>PROBLEM TO BE SOLVED: To provide a lock structure whose opening/closing member is automatically locked when water pressure is applied, and can be manually locked and unlocked. <P>SOLUTION: On the case member 2, a knob guide part 20 which is cylindrical and communicates with the inside of the case member 2, and a knob insertion hole 8 which is integrated with the knob guide part 20 and communicates with the outside of the case member 2 are formed. A first lock knob 4 has a sealing section 15 which slidably seals the knob guide part 20, and part of a second lock knob 5 is exposed to the outside of the case member 2. When the first lock knob 4 slides the knob guide part 20 toward the inside of the case member 2, a lock part of the first lock knob 4 is seized by a lock seizure part 11 formed on a battery lid 3 and the battery lid 3 is locked. On the other hand, when the knob guide part is slid toward the knob insertion hole 8, the lock part comes free from the lock seizure part 11 and the battery lid is unlocked. When water pressure is applied, the first lock knob 4 is slid toward the inside of the case member 2 and the battery lid is locked. The first and second lock knobs can be integrated with each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
