<P>PROBLEM TO BE SOLVED: To prevent pressurizing force of a hook from becoming too small even in the case of pressurizing a striker in the state that the hook is close to the inner peripheral end of a recessed part without changing the size of an energizing spring itself. <P>SOLUTION: A spiral spring 71 energizes a thrust plate by locking a locking outer end 73 to the thrust plate while supporting a locking inner end 72 by a second pivot member 35. In this case, for the spiral spring 71, the position of the center S2 (of the spire) of the spiral spring 71 is positioned at a turning eccentric position shifted with respect to the center position of the second pivot member 35 to be the turning center S1 of the thrust plate. Thus, an energizing direction in which the spiral spring 71 performs energizing is set to a direction shifted from the turning direction of the thrust plate. <P>COPYRIGHT: (C)2012,JPO&INPIT |
