PROBLEM TO BE SOLVED: To make easy grounding of a luminaire to improve workability of wiring by hooking an electrode edge inserted into an electrode edge receiving hole to a pair of electrode souces in a current-carrying condition, and performing connection with a grounding part on the side of a cap in a current-carrying condition. SOLUTION: When an engaged sealing cap 8 to which a luminaire is attached is mounted to an engaged sealing body 1, electrode edges 13, 14 are inserted into electrode edge receiving holes 4, 5 so that a connection condition is established. Further, when the cap 8 is mounted to the body 1, a ground electrode edge 15 is inserted into a ground electrode receiving hole 16, and the edge 15 inserted can be connected to a ground electrode so that the luminaire can be grounded. When the edge 15 is grounded to the ground electrode, a locking claw 15a of the edge 15 is engaged with the ground electrode. The mounting of the engaged sealing cap 8 to the body 1 can be done by the engagement of locking claws 13a, 14a with a power supply electrode as well as the engagement of the claw 15a with the ground electrode and accordingly the engaging portion increase.
