ABSTRACT:
To provide a board unit having an insertion-extraction handle locking structure with which a desired locking force can be easily generated and the locking force is hardly lowered, and which is low in production cost. An insertion-extraction handle5is rotatably supported by a panel body4.A spring unit6is resiliently held in a spring receiving hole45formed in the panel body4and has a first spring part61which, when a stopper part53of the insertion-extraction handle5is inserted into the spring receiving hole45,applies a resistance to the insertion of the stopper part53,and which, when the stopper part53is extracted from the spring receiving hole45,applies a resistance to the extraction of the stopper part53.Second spring parts62of the spring unit6are configured to generate a resistance to removal of the spring unit6which is greater than the resistance to the insertion of the stopper part53between the spring unit6and the spring receiving hole45when the stopper part53is inserted into the spring receiving hole45and to generate a resistance to removal of the spring unit6which is greater than the resistance to the extraction of the stopper part53between the spring unit6and the spring receiving hole45when the stopper part53is extracted from the stopper receiving hole45.
