<p>PURPOSE: To facilitate the lock releasing operation of a lock piece provided to lock a cover for covering the opening of the part housing part of an electronic equipment casing. CONSTITUTION: A lock part 15 provided on a lock piece 11 for locking a cover 3 and a lock groove 6 to be fitted to the lock part 15 have parallelogramic forms, one side part of the lock groove 6 is notched, and the lock part 15 is constituted so as to be elastically deformable toward the notched side of the lock groove 6. When the lock piece 11 laid in the locking state is pressed and elastically deformed, a wedge force is generated by the contact force between each oblique line parts of the lock part 15 and the lock groove 6 to slide the cover 3 in the separating direction by this wedge force. Thus, the lock piece need not be slid, and even when the lock piece is miniaturized, the operability is never deteriorated.</p> |
