PURPOSE:To enable accurate connection between plugs by inserting a positioning pin, provided at a head side elevation body around a movable plug, into a reference hole on the end face plate side at the time of moving the movable plug to a desired fixed plug so as to perform positioning with certain accuracy prior to highly accurate positioning performed by a positioning means. CONSTITUTION:A positioning pin 5 performs positioning in the Z direction with comparatively rough accuracy prior to accurate positioning performed by a positioning means 6. This positioning pin 5 is formed to protrude slightly longer than the fitting pin of a movable plug 17 and also to be fittingly inserted into a reference hole 1d bored on the end face plate 1a side. The positioning means 6 performs the accurate Z-direction positioning of the movable plug 17 in relation to the fixed plug 7, and that this positioning is highly accurate one performed after the position confirmation made by the positioning pin 5 to a certain degree. The movable plug 17 can be thereby connected accurately to an optional fixed plug 7, and the damage or the like of the plug caused by a connection error can be prevented effectively. |
