ABSTRACT:
Three of the side walls of the upper and lower cases are locked together by use of corresponding locking holes and claws. The cases are locked together at the remaining one side at which a mounting stay is provided by a vertically extending locking channel and locking flange, which are provided separately on the upper and lower cases. Any external force working from the stay to open the side wall of the case to the outside is thus restricted by engagement of the locking flange and channel.
