PURPOSE:To make other members than a lidded member freely movable by providing a mechanism capable of fixing one lid common to housings to only one of the members composing the housing. CONSTITUTION:There is provided a retaining part 4 for fitting a lid 1 on only one of the members composing a housing. The other members have no retaining part 4 by which the lid 1 is fitted thereon or, even in a lidded condition, the members composing the lid 1 are placed out of contact with the other members composing the housing within a movable structure range. Even if the members composing the housing are moving, this method prevents the lid from being detached or, even in the lidded condition, the other members are made freely movable. |
