<p><P>PROBLEM TO BE SOLVED: To bring about a locked state by making a hook further driven in a lock turning direction from the state of being engaged with and locked to a striker, without increasing the number of components of the lock device, so as to bring the striker into a backlash-eliminated state. <P>SOLUTION: The hook 20 is turned by being pushed by a motion which makes the striker S get into a recessed portion 11 of a base plate 10, and sandwiches the striker S between the hook and the recessed portion 11. A pole 30 is biased by the turning of the hook 20, so as to engage an engaging projection portion 32 thereof with a portion-to-be-engaged 23A of the hook 20 and regulate the return turning of the hook 20; and a driving surface 33 of the pole is pressed against the driven surface 22A of the hook 20, so as to makes the hook 20 further driven to a lock turning direction side. The hook 20 is pushed in the return turning direction with a strong force, so that the engaging projection portion 32 of the pole 30 can abut on the portion-to-be-engaged 23A of the hook 20 via deformation of an upper jaw portion 22 of the hook 20 and inhibit the movement of the hook 20 in the return rotation direction. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
