Can do. Further, the weight of the wiper blade 10 can be reduced by the amount of reduction in the number of parts. In addition, the inertia force at the time of wiping with respect to the wiping surface 4 can be reduced, and interference with the wiping surface of the wiper blade 10 due to wiping fluctuation can be reduced. Furthermore, the load on the wiper motor (not shown) can be reduced.

  In this embodiment, as shown in FIG. 6, the spring plate member 12 and the holder member 13 are integrally formed together with the cover member 14 by extrusion molding. However, as shown in FIG. 14, the mold piece 10E is provided in the mold 10A to form the molded body 10D having the insertion hole 12a of the spring plate member 12 as shown in FIG. It is good also as a structure which penetrates the member 12 in the penetration hole 12a.

  In this embodiment, the holder member 13 is configured to hold only the head portion 11b of the blade rubber 11. However, as shown in FIG. 10, the blade rubber that holds the head portion 11b of the blade rubber 11 to the holder member 13 is used. A holding plate 13b and a spring plate holding portion 13a surrounding and holding the spring plate member 12 are formed. The spring plate member 12 is inserted into the spring plate holding portion 13a and set in the mold 10A. The spring plate member 12 and the cover member 14 may be integrally molded to form a molded body 10A shown in FIG.

The arcuate recesses 18f are composed of a pair of fitting recesses that are arranged at intervals in the extending direction of the spring plate member 12 and have a shape corresponding to the arcuate columnar part.

  As shown in FIGS. 17, 22 to 24, the pair of holding plates 19 are formed with through holes 19b for inserting rivets between the pair of arcuate columnar portions. As shown in FIGS. 16, 18 and 19, a through hole 18g for inserting a rivet is formed at a location facing the through hole 19b.

  As shown in FIGS. 17 and 25 to 27, the clip member 20 includes a cylindrical portion 20 b extending in a direction crossing the pair of opposing wall portions 18 a and having disc-shaped flange portions 20 a at both ends, and the cylindrical shape. It is formed of a pair of flexible plate-like portions 20c and 20d extending in parallel with each other in the direction in which the spring plate member 12 extends from the portion 20b.

  The pair of flexible plate-like portions 20c and 20d are provided with locking claws 20e for locking the distal end portion 2a of the wiper arm 2 to the flexible plate-like portion 20d facing the spring plate member 12, as shown in FIGS. 27, and an engagement hole 2b that engages with the locking claw 20e is formed in the distal end portion 2a of the wiper arm 2 as shown in FIG.

  The flexible plate-like portion 20d facing the spring plate member 12 has a gap g between the connecting portion 18e connecting the pair of opposing wall portions 18a and the spring plate member 12 at the free end on the side far from the cylindrical portion 20b. An inclined portion 20f that is inclined toward the spring plate member 12 is formed so as to pass (see FIG. 15), and the free end side of the inclined portion 20f is substantially parallel to the other flexible plate-like portion 20c. It is set as the extending parallel part 20g.

  As shown in FIGS. 25 to 29, the disc-like flange portion 20 a of the clip member 20 cooperates with the arcuate recess 20 t (see FIG. 17) to change the swing angle of the wiper blade. A restricting protrusion 20s is formed.

  The clip member 20, the pair of holding plates 19 and the opposing wall portion constituting member 18 are coupled to each through hole 19b, 18g and the cylindrical hole 20h of the cylindrical portion 20b by inserting the rivet 21 shown in FIG. The 21 axis G3 is the transverse axis G1.

  The cylindrical hole 20h of the cylindrical portion 20b has a minimum hole diameter at the center in the transverse direction, and as shown in FIG. 29, the cylindrical hole 20h is formed from a drum-shaped hole whose diameter is increased toward the disc-shaped flange portion 20a. It is configured. The constituent peripheral wall 20j constituting the drum-shaped cylindrical hole 20h is a restricting peripheral wall that restricts the rotation angle of the pair of holding plates 19 and 19 around the orthogonal axis G2.

  According to the embodiment of the present invention, the assembly of the attachment 17 is performed, for example, according to the procedure described below.

  First, each of the pair of holding plates 19 is fitted into each of the arc-shaped recesses 18f of the pair of opposing wall portions 18a so that each of the arc-shaped bulged portions 19a is fitted to each of the pair of holding plates 19 so as to face each other. It is assembled to the wall 18a. Next, the disc-shaped flange portion 20 a of the cylindrical portion 20 b of the clip member 20 is fitted into the circular recesses 19 c of the pair of holding plates 19. At that time, the inclined portion 20f of the flexible plate-like portion 20d is caused to enter the gap g between the connecting portion 18e and the pair of clamping claws 18b, so that the connecting portion 18e is paired with the pair of flexible plate-like portions. It is located between 20c and 20d. Next, the rivet 21 is inserted into each of the through holes 19b and 18g and the cylindrical hole 20h, and the tip portion 21b far from the head 21a of the rivet 21 is caulked to form the clip member 20 and a pair of holding plates as shown in FIG. 19. The opposing wall part constituting member 18 is integrated.

  The effect | action of this attachment 17 is demonstrated below.

  When the blade rubber 11 is moved in the forward movement direction 5 shown in FIG. 1 and when it is moved in the backward movement direction 6 shown in FIG. 1, the inclination angle θ of the wiping surface 4 with respect to the normal N is opposite. For example, as shown in FIG. 30, when the blade rubber 11 moves in the forward movement direction 5 with respect to the wiping surface 4, the opposing wall portion constituting member 18 is relatively disposed with respect to the pair of holding plates 19. When the blade rubber 11 moves in the backward movement direction 6 with respect to the wiping surface 4 as shown in FIG. 31, for example, as shown in FIG. The opposing wall portion constituting member 18 rotates relatively in the opposite direction with respect to 19, and the inclination angle of the wiping surface 4 with respect to the normal line N becomes −θ.

  According to this fixture 17, the orthogonal axis G2 as the rotation center of the blade rubber 11 at the time of wiping forms an intersection point O with the transverse axis G1 as the rotation axis of the blade rubber 11 with respect to the wiper arm 2. Thus, since the height direction displacement between the transverse direction axis G1 and the orthogonal direction axis G2 is eliminated, the height direction dimension of the attachment 17 can be reduced, and the attachment 17 can be made compact. Can be achieved.

  Further, it is possible to rotate the blade rubber 11 around the orthogonal axis G2 by reducing the number of parts to be assembled.

  Furthermore, since the gap H exists between the pair of holding plates 19 and the pair of opposing wall portions 18a, the blade rubber 11 can be smoothly reversed when the blade rubber 11 is reciprocated.

  In addition, an appropriate wiping angle can be obtained with respect to the wiping surface 4 of the front window glass 3 having a different curved shape only by changing the shape of the cylindrical hole 20h of the clip member 20.

  As described above, in the embodiment of the present invention, the pair of holding plates 19 and 19 are formed separately from each other. However, the present invention is not limited to this, and a configuration described below may be employed.

  FIG. 32 is a diagram showing a state before assembly of the pair of holding plates 19, 19, and the pair of holding plates 19 is formed in a flat shape via a connecting portion 19 d. A bent groove 19e is formed between the holding plates 19, 19 and the connecting portion 19d. As shown in FIG. 33, a semi-annular groove portion 19f is provided on the outer peripheral portion of the arcuate bulged portion 19a in order to form a reinforcing ridge portion protruding toward the inside.

  A pair of holding plates 19 shown in FIG. 33 is assembled by raising the holding plate 19 along the bent groove 19e.

  As shown in FIG. 34, the attachment plate 17 is configured by attaching the holding plate 19 to the facing wall constituting member 18.

  The other components are substantially the same as the components shown in FIG. 22, and thus the same components are denoted by the same reference numerals and detailed description thereof is omitted.

  According to this modification, since the pair of holding plates 19 and 19 can be assembled to the opposing wall portion constituting member 18 in an integrally connected state, the assembling work can be further simplified.

  In addition, since the pair of holding plates 19 can be formed in a flat shape, it is possible to simplify the die cutting operation, leading to cost reduction.
