PURPOSE:To detach a couple of elastic engaging pieces diverged toward the end from a tooth of a tape reel by arranging freely slidably a claw main body between couple of guides in a lower half and forwarding the claw to fold up the engaging pieces provided to the tip of the claw toward the inner direction by the guides. CONSTITUTION:In selecting the mode of a video tape recorder into, e.g., the reproduction mode, a lock release pin 103 is forwarded in the direction of arrow (l). The claw 90 is forwarded from the home position to the forward position against a torsional spring 91. In this case, a couple of the elastic engaging pieces 89 of the claw 90 are guided by the edge of a couple of guides 94 and detached surely and very easily from both teeth 106 of a couple of tape reels 8, 9 while being folded up toward the inside against the elasticity. In this case, a couple of claws 88 are turned forwardly against the torsional spring 91, a couple of claws 97 are detached from both the teeth 106 to release the lock of a couple of tape reels 8, 9. Thus, the engaging pieces 89 are detached easily from the teeth 106 in forwarding the claw to ensure the release of lock of the tape reels.
