Rain brush bar 30 has back bar 50, and it is fixing that back bar 50 is supported element 20, and links to each other with rain brush lip 32 by the upwardly extending swing contact pin 34 of axle at rain brush bar 30.Back bar 50 has at least one bar 52 that reclines, and the bar 52 of reclining links to each other with at least one support bar 54 by the upwardly extending contact pin 55 of axle at rain brush bar 30, therefore at the depressed part 51,53 of formation groove shape between bar 52 and the support bar 54 that reclines. Back plate 62 or 64 is arranged in the depressed part 51,53 of these groove shapes.
Supporting member 20 has opposed plate supporting structure 22,24.They constitute axial clearance 27,29 respectively, and axial clearance 27,29 has the intermediate space that almost becomes rectangle in cross-sectional plane, is used for holding back plate 62 or 64. Back plate 62,64 has the longitudinal slot 63 or 65 that constitutes in the axial direction at least partly.Vertically protuberance or longitudinal rib 23,25 embed in these longitudinal slots 63 or 65, vertically protuberance or longitudinal rib 23,25 are arranged in axial clearance 27 or 29 on plate supporting structure 22 or 24, to stop back plate 62,64 in (in Fig. 1) slippage in axial clearance 27 or 29 on the side direction.Particular configuration (geometric configuration of promptly vertical protuberance or longitudinal rib) can freely be selected at this.Correspondingly, for example can use polygonal, the especially groove and the rib of rectangle, replace circular longitudinal fluting and longitudinal rib.
Back plate 62,64 preferably constitutes spring, and has the profile of rectangle in cross-sectional plane, has the side of straight or flat substantially longitudinal side and half rounding, shown in Fig. 2 and 3.This spring for example passes through the one or many operation of rolling by suitable round wire material forming.This operation of rolling can be made into section bar arbitrarily, and therefore above-mentioned rectangle section bar just has exemplary feature, and should not be construed as limitation of the present invention.In the operation of rolling, circular wire rod does not also harden usually, therefore can be out of shape better.Preferably, the spring of making like this hardens and tempering behind the section bar that constitutes expectation.Therefore to this optionally, circular wire rod hardens by moulding in the operation of rolling, can omit hardening afterwards.Certainly also must reduce the inherent stress that exists in the material at this by tempering.
