Specifically, from the front end side of the bracket body 46 to the middle part of the bracket body 46 in the front-rear direction of the vehicle body 2, the width dimension of the bracket body 46 and the cross-sectional area of the bulging portion 48a are gradually reduced. From the middle of the bracket body 46 to the rear end side of the bracket body 46, the width of the bracket body 46 and the cross-sectional area of the bulging portion 48a are substantially constant.

  Further, in the longitudinal direction of the vehicle body 2, a notch 59 is formed in the outer edge of each side outward flange 51 of the wiper bracket 32 at the same position as the middle portion of the bracket body 46 and the bent portion 56. ing. Then, due to the difference in shape between the front and rear portions of the wiper bracket 32 of the wiper bracket 32 and the cutout 59 of each side outward flange 51, the middle portion of the wiper bracket 32 between the front and rear portions is described above. A rigid break point 58 is set.

  According to the above configuration, each section of the wiper bracket 32 in the longitudinal direction of the vehicle body 2 is formed in an inverted U shape, and the front, rear, and lower end edges of the wiper bracket 32 are formed along the inner surface of the cowl inner 16. doing.

  For this reason, each section in the front view of the vehicle body 2 in the combined body 16, 32 of the cowl inner 16 and the wiper bracket 32 of the front cowl 13 has a hollow closed sectional structure, and sufficient strength and rigidity are obtained. Is secured.

  Therefore, firstly, the load applied from the wiper device 31 to the wiper bracket 32 during the normal operation of the wiper device 31 is firmly supported by the combined bodies 13 and 32. For this reason, according to the said wiper apparatus 31, the favorable operation | movement of wiping off the front surface of the said window glass 26 effectively is ensured.

  Second, when the operation of the wiper device 31 is stopped, the wiper blade 38 of the wiper device 31 is normally positioned at the lowermost end of the rotation A locus as described above (FIG. 1). Here, it is assumed that the wiper blade 38 is rotated upward A by the start of the operation of the wiper device 31 in a state where the snow accumulation 61 is generated on the wiper blade 38. In this case, the wiper blade 38 tends to apply a large reaction force downward to the wiper bracket 32 by lifting the snow accumulation 61. However, in this case, the reaction force is also firmly supported by the combination bodies 13 and 32 constituted by the wiper bracket 32. For this reason, the above-mentioned wiper device 31 is ensured to operate well even under the severe conditions described above.

  Further, as described above, the front, rear, and lower end edge portions of the wiper bracket 32 are formed along the inner surface of the cowl inner 16, that is, at least the lower side of the wiper bracket 32 is fitted into the cowl inner 16. It is structured.

  For this reason, first, when the wiper bracket 32 is assembled to the cowl inner 16, the wiper bracket 32 can be easily positioned to the cowl inner 16 by the fitting. Therefore, the above assembling work can be facilitated accordingly.

  Second, the wiper bracket 32 prevents the air from freely flowing in the inner space of the front cowl 13 in the width direction of the vehicle body 2 by fitting the wiper bracket 32 into the cowl inner 16 described above. The Therefore, for example, air warmed by the engine in the engine room 3 flows from one end of the cowl inner 16 and flows toward the other end, so that the warm air passes through the outside air inlet 24 and is unintentionally Thus, it is possible to prevent the vehicle from flowing into the passenger compartment 5 side.

  Further, a bent portion 56 is formed in the middle portion of the front plate 19 of the cowl inner 16 in the vertical direction, and the wiper bracket 32 is supported at both ends on the front and rear of the cowl inner 16 so as to straddle the bent portion 56. A rigid break point 58 is formed in the middle of the wiper bracket 32 in the vicinity of the bent portion 56 in the front-rear direction.

  Here, when the vehicle 1 travels, generally, impact force is applied to the skeleton member 10 of the vehicle body 2 from the traveling surface side via the wheels, and the cowl inner 16 tends to vibrate in conjunction with this. In this case, as described above, the cross section of the cowl inner 16 is U-shaped, and the front plate 19 has a cantilever support structure protruding upward from the bottom plate 21. For this reason, especially the upper part which is a free end part of this front plate 19 may vibrate greatly (in FIG. 3, a dashed-dotted line).

  If the front plate 19 of the cowl inner 16 vibrates as described above, the wiper bracket 32 tends to vibrate in conjunction with the vibration of the front plate 19. However, as described above, the bent portion 56 is formed in the middle portion of the front plate 19 of the cowl inner 16, and in the middle portion of the wiper bracket 32 supported at both ends by the cowl inner 16 so as to straddle the bent portion 56. A rigid break point 58 is formed.

  Therefore, the vibration from the skeleton member 10 is transmitted to the upper part of the front plate 19 above the bent part 56 and the front part of the wiper bracket 32 ahead of the rigid break point 58. 32 is mainly vibrated, while transmission of vibrations to the lower side of the front plate 19 and the rear side of the wiper bracket 32 is suppressed by the bent portion 56 and the rigid break point 58.

  Therefore, since the overall vibration of the cowl inner 16 and the wiper bracket 32 is suppressed, the dash panel 14 coupled to the bottom of the cowl inner 16 is also prevented from vibrating in conjunction with this vibration. Is done. As a result, the occurrence of road noise in the passenger compartment 5 based on the vibration of the dash panel 14 is suppressed.

  Further, when the vehicle 1 collides with a certain object in front of the vehicle 1 while traveling forward (front collision), the object may jump up and collide with the cowl inner 16 from above.

  In the above case, the front plate 19 of the cowl inner 16 located in front of the lower edge of the windshield 26 is inclined forward and upward from the bottom plate 21 when viewed in cross section of the vehicle body 2 in the width direction. The cantilever support structure protrudes into Moreover, as described above, the bent portion 56 is formed in the middle portion of the front plate 19, and a rigid breakpoint is provided in the middle portion of the wiper bracket 32 supported at both ends by the cowl inner 16 so as to straddle the bent portion 56. 58 is formed, and the bent portion 56 and the rigid break point 58 are weak portions where stress concentration easily occurs.

  Therefore, as described above, when the object bounced up by the front collision collides with the front plate 19 of the cowl inner 16 from above, the front plate is particularly separated from the bent portion 56 or the rigid break point 58 as a boundary. The front upper side of 19 is plastically deformed so that it bends easily. Therefore, the impact force when the object collides against the cowl inner 16 is effectively reduced.

  Although the above is based on the illustrated example, the rigid break point 58 may be formed by devising the position and shape of the opening 52 in the wiper bracket 32. Further, a slight gap is formed between the upper surface of the bottom plate 21 of the cowl inner 16 and the lower edge of each side plate 47 of the wiper bracket 32 so as to ensure the drainage of rainwater and the like. May be.
