Claim:
1. A lock device for an opening and closing member attached to a main member, comprising: a housing including a front face, a back face located opposite to the front face so as to form a space therebetween and having a window portion opened outwardly, and a support shaft protruding from the front face toward the window portion in the space; a pair of rods slidably supported in the housing and respectively including end portions adapted to be engaged with and disengaged from lock holes in a panel, and back side portions with inclination portions, the rods sliding in first and second linear directions relative to the housing to move between a lock position separated from each other, in which the end portions are engaged with the lock holes, and a release position approaching each other, in which the end portions are disengaged from the lock holes; an operating member turnably attached to the housing and including arm portions, each of the arm portions protruding toward a respective one of the rods to abut against a respective one of the inclination portions, the operating member turning in a direction from an initial state to an operating state to switch the rods from the lock position to the release position; a connection member disposed on the support shaft and including one end engaging the back side portion of one of the rods, and another end engaging the back side portion of the other one of the rods, the connection member urging the rods in the first linear direction to move away from each other and be separated; and an urging member disposed between the housing and the operating member, and providing an opening force on the operating member, the opening force being less than an urging force of the connection member urging the rods in the first linear direction so as to damp the movement of the operating member back to the initial state from the operating state, wherein when the operating member is turned from the initial state to the operating state, the rods slide in the second linear direction to approach each other against the urging force of the connection member through a cam operation between the inclination portions and the arm portions, and each of the rods includes a concave portion which forms each of the inclination portions thereon, and each inclination portion is outwardly tapered from each of the back side portions such that the respective arm portions press the respective inclination portions to provide the cam operation.
