To prevent certainly pulling-off of a cable such as a power supply cord while being held integrally with electronic equipment.

A wire 60 which includes a rotating shaft part 61, a nearly L-shape arm 62, and a coupling part 63 with a nearly semi-circular part 64 formed in the center, is axially supported rotatably at a fulcrum 52 in the vicinity of a socket (AC inlet or outlet) 51 of a socket assembly 50 of an electronic equipment case. This wire 60 is, in the non-connection state of the cable 71, held by a plate spring 53 in a state of falling down (arm part 62 of the wire 60 is in nearly parallel with the face of the electronic equipment case) and, in the connection state of the cable 71, is made to stand up and, by pressing the pressing part 63 on the shoulder portion 73 of the cable is prevented from pulling-off.
