  For example, when a single radiator is used, the projected area of the radiator on the front side of the vehicle is limited by the shape of the vehicle body frame 11. In the present invention, the left radiator 262 and the right radiator 263 are connected to the lower frame 101. The center radiator 264 extends downward between the left frame 161 and the right frame 162, so that the floor frame 101 is skillfully avoided, and the projection area of the radiator 261 on the front side of the vehicle is less likely to be limited. Thus, the projected area can be further increased. Therefore, the cooling capacity of the radiator 261 can be improved.

  Furthermore, by making the upper end of the central radiator 264 lower than the upper ends of the left radiator 262 and the right radiator 263, the space above the central radiator 264 can be used effectively.

  As described above with reference to FIGS. 3, 6, and 10, the present invention is a skid plate having a substantially M-shaped upper edge portion in front view of the vehicle body frame 11 in order to protect the vehicle body front portion. 24 is attached.

  By making the upper edge of the skid plate 24 substantially M-shaped when viewed from the front, the M-shaped ends, that is, the upper left and right ends and the lower left and right ends protrude. By covering the left and right swing members 173 and 174, the bases of the upper arms 61 and 62, the bases of the lower arms 63 and 64, and the like as the constituent parts, it is possible to effectively protect the constituent parts of the front suspension 17 with the skid plate 24. Can do.

Secondly, the present invention is characterized in that the left and right front cushion units 21 and 21 extend substantially in the front-rear direction, and an M-shaped peak portion of the skid plate 24 covers the front end thereof.
Since the front ends of the front cushion units 21 and 21 are covered with the M-shaped peaks of the skid plate 24, the front ends of the front cushion units 21 and 21 can be protected by the skid plate 24, and the front ends of the front cushion units 21 and 21 can be protected. You can avoid stepping stones.

Thirdly, the present invention is characterized in that the skid plate 24 is attached to a front frame portion 106 of an underframe 101 as a casting tapered front frame.
Since the skid plate 24 is attached to the front frame portion 106 having a tapered shape, the skid plate 24 can be firmly supported by the front frame portion 106, and vibration of the skid plate 25 can be prevented.

Fourthly, according to the present invention, a pair of upper and lower suspension arms 61 and 62 and lower arms 63 and 64 are provided on the left and right sides of the vehicle body, and push rods 171 and 172 as rods are provided on the lower arms 63 and 64 below the suspension arms. And the front ends of the push rods 171 and 172 were connected to the front cushion units 21 and 21 via delta links 173 and 174 as link members, and the skid plate 24 covered the front of the delta links 173 and 174. It is characterized by.
Since the front of the delta links 173 and 174 is covered with the skid plate 24, the delta links 173 and 174 to which a large load acts from the lower arms 63 and 64 via the push rods 171 and 172 can be reliably protected. The reliability of the leveling vehicle 10 can be increased.

  In the present invention, the skid plate is substantially M-shaped when viewed from the front. However, the present invention is not limited to this, and the skid plate is viewed from the front as H-shaped, U-shaped, V-shaped, W-shaped, Y-shaped. It is good also as a shape, X shape, or a shape close | similar to these.

  The skid plate of the present invention is suitable for a vehicle that travels on leveled and uneven terrain.
