Abstract

PURPOSE:To prevent a lock lug from falling off independent of the angle of an indicator case by a method wherein a disengagement preventing means is provided to the pawl of the lock lug and the case of an indicator. CONSTITUTION:A lock pawl is provided to lock or release cases 6 and 7 or a lid to or from an electronic equipment body. A disengagement preventing means which prevents a lock pawl from being disengaged from the electronic equipment body is provided when the lock pawl is built in. That is, a projection 7b is provided to the thick-walled part of the case 7 of an indicator, and a step difference 8a is provided to a lock lug 8. By this setup, even if the lug is moved in a releasing direction, the step difference 8a is engaged with the step difference 7b to prevent the lug 8 from being disengaged. Therefore, when an indicator is built in an electronic equipment, a lug is not required to be held.
