Claims

1. A lid lock device for locking a lid which is mounted in a box and which is opened and closed, the lock device comprising: a housing fixed to either of the lid and the box;a hook member slidably supported on the housing so as to be brought into engagement with and disengagement from a lock portion provided on the other of the lid and the box;an elastic biasing unit for biasing the hook member in a direction in which the hook member is brought into engagement with the lock portion;a control member slidably supported on the housing so as to control the movement of the hook member; anda translating unit for translating the control member between a closing corresponding position and an opening corresponding position, wherein:the hook member includes: a hook portion which is brought into direct engagement with and disengagement from the lock portion; and an operating portion for translating the hook portion from a closing corresponding state to an opening corresponding state;a first wall and a second wall are provided on either of the hook member and the control member to define an inner space therebetween;a recessed portion is formed on either of the first wall and a second wall; anda raised portion, entering between the first wall and the second wall and confronting both the walls, is formed on the other of the hook member and the control member;when the control member is translated to the closing corresponding position by the translating unit, the raised portion is brought into abutment with other portions of a wall surface than the recessed portion so as to prevent the operation of the operating portion; andwhen the control member is translated to the opening corresponding position by the translating unit, the raised portion is made to enter the recessed portion so as to enable the operation of the operating portion against a biasing force of the elastic biasing unit.

2. The lid lock device according to claim 1, wherein one end portion of the control member is supported by the traveling unit, and the other end portion thereof is supported by the housing.

3. The lid lock device according to claim 1, further comprising an elastic arm provided between the control member and the housing, the elastic arm pushing the control member in a same direction as a biasing direction of the hook member by the elastic biasing unit.
