Patent ID: 7494387

Claim:
An electric contact disposed between a first electrical part and a second electrical part so as to electrically connect the first and second electrical parts, comprising: a first electrical part side contact member contacting the first electrical part; a second electrical part side contact member contacting the second electrical part, a coil spring urging the first electrical part side contact member and the second electrical part side contact member in a direction separating from each other, the coil spring including a first spring portion abutting against the first electrical part side contact member and a second spring portion abutting against the second electrical part side contact member, wherein when the first electrical part contacts the first electrical part side contact member, an axis of the first spring portion inclines with respect to an axis of the second spring portion, and then, a portion of the first electrical part side contact member on a side contacting the first electrical part is transversely moved, and the first spring portion of the coil spring is a first close winding portion closely wound-up at a minimum pitch, the second spring portion is a normal winding portion including portion having a normal winding portion wound-up at a predetermined pitch, a rough winding portion is continuously formed between the first close winding portion and the normal winding portion so as to have a pitch larger than that of the first close winding portion and smaller than that of the normal winding portion, and when the first electrical part contacts the first electrical side contact member, the rough winding portion is contracted so that a lower portion of the first close winding portion and an upper portion of the normal winding portion including portion are contacted to each other.
