PROBLEM TO BE SOLVED: To provide a stable contact condition by providing contact spring pieces of a spring part with a contact part for contacting to a counterpart contact in the behavior independent each other. SOLUTION: This spring part has a pair of contact spring pieces 13 and 14 independent each other which are connected to one end of a holding piece and bent in a chevron shape. The contact spring pieces 13 and 14 are bent in an arc shape at contact parts of first and second contact base pieces 13a, 14a, 13b and 14b and have contact parts 13c and 14c on the outer side. When a counterpart contact is pressed into a contact 1, the respective contact parts 13c and 14c are pressed by the contact face of the counterpart contact and a pair of the contact spring pieces 13 and 14 are greatly deformed and pressed upward as the holding piece being deformed as well. In this condition, a pair of the contact spring pieces 13 and 14 are completely separated by a slit 21 so that the respective contact parts 13c and 14c come into contact with the counterpart contact face in the behavior independent each other as a constant load ratio being kept to the counterpart contact face all the time. |
