Abstract

PURPOSE:To obtained the sure releasing function of a lock tool by dislocating the operating point of the spring member of a reverse V-character shape, which suppresses and energizes the lock tool in the direction of a lock position, in the lower direction of the central position of a releasing projection and providing a space between the spring member and the almost upper half part of the lock tool. CONSTITUTION:A spring member 22 of the reverse V-character shape, which suppresses and energizes a lock tool 10 in the lock position direction, is inserted between the lock tool 10 and a spring receiving part 19 and an operating point of the spring member 22 is set in the lower direction of the central position of a releasing projection 14. Then, a space T is provided between the spring member 22 and the almost upper half part of the lock tool 10 so that a lock claw 13 can be inclined in a direction in which it is taken off from a front cap 6. Accordingly, even when a releasing operating member P of a VTR side is suppressed from the lower direction to the releasing projection 14, the lock tool 10 is revolved and operated in a direction in which it is taken off from the front cap 6 and it can be almost parallely moved to an un-lock position. Thus, the front cap releasing function with high security and reliability can be shown.
