An inner sandwiching piece 14c having a smaller front-rear dimension than the sandwiching piece 14b is formed by bending downward, and its cross-sectional shape is a U-shape when viewed from the front (see FIG. 5). The dimension between the opposing surfaces of the outer clamping piece 14b and the inner clamping piece 14c is substantially equal to the plate thickness so that the support bracket 8 can be inserted without any gap. Further, the vertical dimension of the inner clamping piece 14c is smaller than the vertical dimension of the outer clamping piece 14b so that a locking projection 15 described later provided on the inner surface of the outer clamping piece 14b can be easily seen.

  The inner surface of the center portion in the front-rear direction of the outer sandwiching piece 14b is locked in a hemispherical cross section by being strongly pressed by a press or the like from the outside and plastically deformed inward in the manufacturing process of the outer sandwiching piece 14b. A projecting portion 15 is provided. The clearance between the tip of the locking projection 15 and the inner clamping piece 14c is slightly elastically deformed by either one or both of the outer clamping piece 14b and the inner clamping piece 14c, so that the support bracket 8 is strongly clamped. The size is smaller than the plate thickness of the support bracket 8 so that it can be inserted.

  In the front end portion of the support bracket 8, a long hole 16 in the front-rear direction that can be loosely fitted from the inside is formed in the protruding piece 13 of the side rod 12. The vertical width of the long hole 16 is such that the projecting piece 13 can be fitted to the projecting piece 13 with the support bracket 8 slightly tilted rearward and downward, as shown by a two-dot chain line in FIG. The thickness is greater than 13 (see FIG. 4).
