These anchor clamps 17 are installed on the elastic plate part 12.This windscreen wiper sheet 11 to shown in Figure 1 toward moving direction 5 when movable and when double action direction shown in Figure 16 is movable, the tilt angle theta of the normal N of wiping surface 4 is opposite relatively, for example shown in Figure 22, when windscreen wiper sheet 11 moves relative to the moving direction 5 of wiping surface 4 yearnings, wall portion component parts 18 a pair of relatively holding plates 19,19 relatively rotate, the angle of inclination of the normal N of wiping surface 4 is θ relatively, for example shown in Figure 23, windscreen wiper sheet 11 relative to wiping surface 4 when double action direction 6 moves, wall portion component parts 18 a pair of relatively holding plates 19,19 relatively rotate round about, and the angle of inclination of the normal N of wiping surface 4 is-θ relatively.
According to the embodiment of the present invention, the vertical direction axis G2 of the center of turn of windscreen wiper sheet 11 is vertical with transverse direction axis G1 as the pivot center of windscreen wiper sheet 11 relative windscreen wiper arms 2 during as wiping, form intersection point O, so eliminate transverse direction axis G1 and vertical direction axis G2 in this part of the difference of short transverse, the size of anchor clamps 17 short transverses can be reduced, the miniaturization of anchor clamps 17 can be realized.
In addition, can reduce assembling parts quantity, windscreen wiper sheet 11 is rotated around the vertical direction axis G2.
And, have gap H between a pair of holding plate 19,19 and a pair of wall 18a of portion, the 18a, so windscreen wiper sheet 11 counter-rotatings smooth and easy can realize that windscreen wiper sheet 11 moves back and forth the time.
In addition, only change the shape of the tube hole 20h of clamp assembly 20, the differently curved shape of the wiping surface 4 of front screen 3 can access suitable wiping angle relatively.
In the embodiments of the present invention, a pair of holding plate 19,19 forms respectively, but is not limited thereto, and also can be the structure of following explanation.
Figure 24 is the figure of the state before 19 assemblings of expression holding plate, and a pair of maintenance wall 19h, 19h form flat tabular by connecting part 19d.Keep forming between wall 19h, 19h and the connecting part 19d crooked ditch 19e, 19e to the inside bending.
As shown in figure 26 this holding plate 19 is installed on the wall portion component parts 18, constitutes anchor clamps 17 thus.
Other structural elements and structural element shown in Figure 14 are roughly the same, so same structural element uses prosign, omit its detailed description.
According to this variation, can under the state that a pair of holding plate 19,19 connects as one, be assembled on the wall portion component parts 18, so can simplify assembly operation more.
In addition, windscreen wiper 10 too, as shown in figure 27, when windscreen wiper sheet 11 moved relative to the moving direction 5 of wiping surface 4 yearnings, wall portion component parts 18 relative holding plates 19 relatively rotated, and the angle of inclination of the normal N of wiping surface 4 is θ relatively, as shown in figure 28, when double action direction 6 moved, wall portion component parts 18 relative holding plates 19 relatively rotated windscreen wiper sheet 11 round about relative to wiping surface 4, and the angle of inclination of the normal N of wiping surface 4 is-θ relatively.
And it is flat tabular that a pair of holding plate 19,19 is formed, so can simplify modulo operation, can also reduce the cost.
More than, the windscreen wiper of the windscreen wiper lid that has used 3 segmenting structures that constitute according to the anchor clamps of rolling structure of the present invention and elastomeric material has been described among the embodiment 1, the windscreen wiper lid also can be an integrative-structure.
