A gap section reaching a pivot shaft hole is provided in a head connection section of a retainer. A recess is provided on a pivot shaft section of an arm head. During the retainer rotates, a straight section of the coil spring moves from the gap section to the recess.

The pivot shaft section includes a projection disposed within the gap section and in contact with the divided pieces, on the both sides of the gap section.
