  A steel plate dashboard 21 is provided below the cowl top 3. On the upper side of the dashboard 21, a windshield lower 26 made of a steel plate that supports the lower part of the windshield 5 is provided. The dashboard 21 includes a dashboard upper 22 and a dashboard lower 23. The dashboard upper 22 is disposed on the upper side of the dashboard lower 23 and, together with the cowl top 3, constitutes a gas-liquid separation chamber for air-conditioner intake. The dashboard lower 23 is disposed below the rear end of the dashboard upper 22 and partitions the engine room 8 and the vehicle compartment 7. The dashboard 21 (dashboard upper 22 and dashboard lower 23) and the windshield lower 26 constitute the vehicle body 2.

  The cowl top 3 is made of resin. The cowl top 3 includes a cowl top upper 31 and a cowl top lower 32 continuously provided below the cowl top upper 31. Here, the cowl top upper 31 and the cowl top lower 32 are integrally formed.

  The cowl top upper 31 is located between the windshield 5 and the hood 6, and is disposed such that a portion thereof is exposed to the outside. The cowl top upper 31 has a fitting groove 33 fitted to the lower end of the windshield 5 at the rear end thereof. The fitting groove 33 has a substantially U-shaped cross section, and the lower end of the windshield 5 is inserted inside the fitting groove 33.

  As shown in FIGS. 3 to 4, a mesh-like outside air inlet 34 is formed in the front portion of the cowl top upper 31. The outside air introduction port 34 extends a predetermined length in the vehicle width direction. Further, the cowl top upper 31 is formed with a wiper mounting hole 35 through which the rotation shaft 91 (see FIG. 6) of the wiper 9 (see FIG. 1) is inserted. The wiper attachment holes 35 are formed at two locations, that is, an intermediate portion in the vehicle width direction and one end portion in the vehicle width direction. Attachment holes 31 a and 31 b for attaching the cowl top upper 31 to the vehicle body 2 are formed in the vicinity of the end of the cowl top upper 31 on the side of the vehicle compartment 7 (see FIG. 9). In addition, mounting holes 32 a and 32 b for mounting the cowl top lower 32 to the vehicle body 2 are formed in the vicinity of the end of the cowl top lower 32 on the side of the compartment 7 (see FIG. 2). The mounting holes 31a and 32a on the center side in the vehicle width direction are circular holes.

Moreover, the vertical direction positioning part 271 has the attachment surface 271b formed along the fitting direction A (refer FIG. 2) to the windshield 5 of the fitting groove 33. FIG. In other words, the attachment surface 271b (the same applies to the attachment surface 251 described later) is formed in parallel to the fitting direction A. Here, “parallel” is a concept that includes not only strict parallelism but also substantially parallel that can be seen in parallel from the viewpoint of technical common sense. The fitting direction A coincides with the groove depth direction of the fitting groove 33.

  First, the vertical positioning portion 271 and the cowl top upper 31 are generally positioned in the vertical direction in advance by receiving the tip of the vertical positioning portion 271 with the pair of receiving portions 421 and 421. Next, the fixing tool 11 such as a clip is inserted into the long hole 271 a through the attachment hole 31 a of the cowl top upper 31 and the boss portion 422 of the cowl top upper attachment portion 42. Accordingly, the cowl top upper 31 is detachably attached to the vertical positioning portion 271 of the windshield lower 26. The fixture 11 is restricted from moving in the vertical direction within the long hole 271a, but is allowed to move in the vehicle width direction. As a result, the cowl top upper 31 is positioned in the vertical direction. The vertical positioning portion 271 engages with the fixture 11 just below the fitting groove 33 of the cowl top upper 31.

  As shown in FIG. 11, when viewed from the outside of the vehicle 100, the fixing tool 11 is set so as to be substantially hidden by the wiper 9. This improves the appearance.

  As shown in FIGS. 6-7, the vehicle width direction positioning part 272 has the cowl top 3 on the other side (here, the right side) of the left and right sides in the vicinity of the vehicle width direction center line CL (see FIG. 7). Positioning in the vehicle width direction. The vehicle width direction positioning portion 272 has a recessed portion 272 a that is recessed downward at the front end portion of the windshield lower 26.

A protrusion 43 is provided on the rear surface of the cowl top upper 31 so as to project downward toward the rear side. The protrusion 43 has an H-shaped vertical cross section, and has a shape of high rigidity. When the projection 43 enters the recess 272 a of the vehicle width direction positioning portion 272, the cowl top upper 31 is positioned in the vehicle width direction.
As shown in FIG. 10, the vehicle width direction positioning portion 272 engages with the protrusion 43 on the back side (rear side) of the fitting groove 33 of the cowl top upper 31.

  As shown in FIGS. 2 and 7, the second vehicle body side mounting portion 25 has a mounting surface 251 (FIG. 2) formed along the fitting direction A (see FIG. 2) of the fitting groove 33 to the windshield 5. See). A circular hole 252 is formed through the second vehicle body side attachment portion 25. The circular hole 252 is located on the vehicle width direction center line CL (see FIG. 7).

  As shown in FIG. 2, the cowl top lower side attachment portion 37 of the cowl top lower 32 is a portion that is attached to and connected to the second vehicle body side attachment portion 25 provided at the upper end portion of the dashboard upper 22. The cowl top lower side attachment portion 37 is a plate-like member that is continuous with the lower end portion of the inclined surface portion 36, and is folded back to the front lower side. The cowl top lower side attachment portion 37 is formed along the fitting direction A of the fitting groove 33 of the cowl top upper 31 to the windshield 5. The cowl top lower side attachment portion 37 is in contact with an attachment surface 251 formed on the second vehicle body side attachment portion 25 of the dashboard upper 22 and is detachably attached by a fixing tool 12 such as a clip. A bent portion 41 that is bent backward is formed at the lower end portion of the cowl top lower mounting portion 37.
