PROBLEM TO BE SOLVED: To keep correct contact of a contact pin with a holder and prevent contact failure by fastening one end of a coil spring made of a conductor in the diameter direction of a receiving boss within the holder to connect to the boss, and fastening the other end of the coil spring in the diameter direction of a receiving boss formed in the contact pin to connect to the boss. SOLUTION: A contact pin 66 is energized outward with a coil spring 78 arranged within a recess 77 of a holder 67. A receiving boss 79 on the holder 67 side is formed within the recess 77, and a receiving boss 80 is formed so as to face the receiving boss 79 to the contact pin 66. Both ends of the coil spring 78 are forced to extend in the radial direction and the receiving bosses 79, 80 are pushed in the coil spring 78 to connect to the coil spring 78. The coil spring 78 is a compressed coil spring made of phosphor bronze, and plated with 0.1μm thick gold. The outer circumferential surface on base end side of the contact pin 66 is brought into contact with the inner circumferential surface of the recess 77, and even if centrifugal force is applied, correct contact is kept.
