  In the present embodiment, the bracket 18 that supports the second headlamp 17 is fixed to the inner surface of the bonnet 10, but may be fixed to the support frame 29. By fixing the bracket 18 to the support frame 29, the second headlamp 17 can be supported by the support frame 29. When the second headlamp 17 is supported by the support frame 29, for example, the one headlamp 17 </ b> L is supported by the first extending portion 44 of the second horizontal frame 42, and the other headlamp is supported by the second extending portion 45. 17R can be supported.

  As shown in FIG. 7, on the inner surface (rear surface) of the support frame 29, a harness clamp 36, which is a harness support portion for supporting a harness (not shown), is provided. The harness clamp 36 is provided between the first horizontal frame 41 and the second horizontal frame 42 of the first vertical frame 31, the first support portion 63, the second support portion 64, the first horizontal frame 41, and the second horizontal frame 41. The frame 42 is attached. The harness clamp 36 is attached to the first vertical frame 31 via a clamp attachment plate 37 between the first horizontal frame 41 and the second horizontal frame 42 of the first vertical frame 31.

  The harness supported by the harness clamp 36 is, for example, an electric cable connected to the first headlamp 16, the second headlamp 17, the horn 35, or the like. Since the harness clamp 36 is attached to the inner surface of the support frame 29, the harness is positioned along the support frame 29 toward the first headlamp 16, the second headlamp 17, the horn 35, and the like. It can be arranged.

  As shown in FIGS. 6 to 9, the base frame 50 includes a front collar 51, a first side collar 52 </ b> L, and a second side collar 52 </ b> R. The front collar 51, the first side collar 52L, and the second side collar 52R are integrally formed, and are connected in a substantially U shape in plan view. In addition, from the viewpoint of the strength (rigidity) of the base frame 50, the front flange 51, the first side flange 52L, and the second side flange 52R are preferably formed integrally, but are separate (separate members). May be formed. When formed separately, the front collar 51 and the first side collar 52L are connected via the first vertical frame 31 and the first member 61 (the first support part 63 and the first connection part 65). . The front flange 51 and the second side flange 52R are connected to each other through the second vertical frame 32 and the second member 62 (second support portion 64 and second connection portion 66).

  As shown in FIGS. 3 to 5, the front brim 51 extends along the lower part of the inner surface of the front plate 10 </ b> F of the bonnet 10, and is connected to the first vertical frame 31 and the second via the second connecting plate 34. The vertical frame 32 is connected. The front flange 51 is located below the front grille 15 (below the first opening 11) and is connected to the lower part of the second connecting plate 34. The first side flange 52L extends rearward along the inner surface of one side (left side) of the bonnet 10, and a fixing member 53L is fixed to the rear end portion. The second side flange 52R extends along the inner surface of the other side (right side) of the bonnet 10, and a fixing member 53R is fixed to the rear end.

  The fixing member 53L is connected to the first fixing plate 23 provided on the left part of the reinforcing frame 22. The fixing member 53 </ b> R is connected to the second fixing plate 24 provided at the right part of the reinforcing frame 22. As a result, the support frame 29 and the reinforcement frame 22 are connected via the fixing members 53L and 53R, the first fixing plate 23, and the second fixing plate 24. In this way, the strength (rigidity) of the support frame 29 is enhanced by the reinforcement frame 22 by connecting the support frame 29 and the reinforcement frame 22. Therefore, the stability of the support of the first headlamp 16 can be improved. Further, since the support frame 29 and the reinforcing frame 22 can integrally reinforce the bonnet 10, the reinforcing effect is improved.

  As shown in FIGS. 3, 4, 7, 8, and 10, a first inclined portion 511 is provided on one side (left side) of the front rod 51. The 1st inclination part 511 inclines upward so that it may become a high position as it approaches the side plate 10L. A second inclined portion 10 </ b> R is provided on the other side (right side) of the front collar 51. The second inclined portion 512 is inclined upward so as to become a higher position as it approaches the side plate 10R. The first inclined portion 511 is connected to the front portion of the first side portion flange 52L, and the second inclined portion 512 is connected to the front portion of the second side portion flange 52R. Accordingly, the first side collar 52L and the second side collar 52R are positioned above the front collar 51.

  As shown in FIGS. 6, 7, and 10, the first side flange 52 </ b> L is connected to the first connecting portion 65 of the first member 61 fixed to the first vertical frame 31. The second side flange 52R is connected to the second connection portion 66 of the second member 62 fixed to the second vertical frame 32. Thereby, since the vertical frame 30 and the base frame 51 are connected, the strength (rigidity) of the support frame 29 can be improved. Further, the strength (rigidity) of the support frame 29 is improved, so that the first headlamp 16 can be stably supported.

  As shown in FIG. 9, in plan view (top view), the first connecting portion 65 of the first member 61 is more to the left (in the vehicle body width direction) than the front flange 51 and the first inclined portion 511 of the base frame 50. It is located outside. The second connecting portion 66 of the second member 62 is located on the right side (outward in the vehicle body width direction) of the front frame 51 and the second inclined portion 512 of the base frame 50. Moreover, the 1st inclination part 511 is extended in the direction (inward of the vehicle body width direction) which leaves | separates from the 1st connection part 65 as it goes ahead. The second inclined portion 512 extends in the direction away from the second connecting portion 66 (inward in the vehicle body width direction) as it goes forward.

  As indicated by a one-dot chain line L1 in FIG. 10, the first connecting portion 65 extends so as to incline upward toward the front from the height of the first side flange 52L. On the other hand, as indicated by the alternate long and short dash line L2, the first inclined portion 511 of the base frame 50 extends so as to incline downward toward the front from the height of the first side flange 52L. Therefore, the distance between the first connecting portion 65 and the first inclined portion 511 gradually increases toward the front. In other words, the first connecting portion 65 and the first inclined portion 511 extend while being spaced apart upward and downward so as to expand in a V shape from the height of the first side flange 52L toward the front. The positional relationship between the second connecting portion 66 and the second inclined portion 512 is the same as the positional relationship between the first connecting portion 65 and the first inclined portion 511. That is, as shown in FIG. 5, the distance between the second connecting portion 66 and the second inclined portion 512 gradually increases toward the front.

  As shown in FIGS. 7, 9, and 10, the support frame 29 has a locking portion 54. Specifically, the locking portion 54 is provided on the front collar 51 of the base frame 50. The locking portion 54 is lockable (detachable) with respect to a receiving portion 55 (see FIG. 11) provided on the vehicle body frame 5 of the vehicle body 2. By locking the locking portion 54 provided on the front collar 51 with respect to the receiving portion 55 provided on the vehicle body frame 5, the hood 10 is locked in a closed state. Further, by releasing the locking of the locking portion 54 with respect to the receiving portion 55, the lock is released and the bonnet 10 can be opened with the hinge portion 27 as a fulcrum.

  The support frame 29 is fixed to the inner surface of the bonnet 10 but is not fixed to the vehicle body frame 5. Therefore, the support frame 29 rises following the hood 10 when the hood 10 is opened, and descends following the hood 10 when the hood 10 is closed. Accordingly, the first headlamp 16 can be stably supported by the support frame 29 in both the opened state and the closed state of the bonnet 10.

  In the above-described embodiment, the first headlamp 16 is supported by the support frame 29, but both the first headlamp 16 and the second headlamp 17 may be supported, Instead of the first headlamp 16, a second headlamp (work lamp) 27 may be supported. That is, the headlamp supported by the support frame 29 may be located at the upper part of the front plate 10F of the bonnet 10, may be located at the lower part, or may be an intermediate part in the vertical direction. It may be located.

  As mentioned above, although this invention was demonstrated, it should be thought that embodiment disclosed this time is an illustration and restrictive at no points. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
