PROBLEM TO BE SOLVED: To reduce the size. SOLUTION: A large contact pressure is secured in an elastic contact piece 23, because the contact piece 23 is supported in two points of a base end part 24A in the first plate spring part 24 and an extended end (coming-off preventive part 30) in the second plate spring part 29 by a bottom plate 14. Since the first and second plate spring parts 24, 29 are formed into a turned-up form, a longitudinal length of the elastic contact piece 23 is short compared with that of a V-shaped elastic spring. Since an extended part in the first plate spring part 24 is adjacent to a base end in the second plate spring part 29 via a close-contact turned-up part 26, the height difference gets small compared with one adjacent via a substantially U-shaped turned-up part, and the elastic contact piece 23 is thereby allowed to become low.
