By the way, in a vehicle in which the rear end side of the engine below the cab protrudes rearward from the opening (inner space) of the portal support member (cab back member), the cab back member, as in the vehicle described in Patent Document 1, Since the inner space cannot be blocked by the air cleaner device, the running wind passing under the cab when the vehicle is running passes through the inner space of the cab back member in a state of being heated by the internal combustion engine which is a heat source device and becoming hot. Then, it hits the front of the rear cargo box and may flow upward along the front of the cargo box or outward in the vehicle width direction. When the running wind warmed by the internal combustion engine and becomes hot flows upward along the front of the packing box or outward in the vehicle width direction, the running wind hits the peripheral devices around the rear of the cab, and the temperature of the peripheral devices rises. There is a possibility that it will end up. In order to prevent this, it is conceivable to provide a wind guide member that covers the inner space of the cabback member from behind the internal combustion engine. However, if the wind guide member is provided behind the internal combustion engine, it is behind the wind guide member. There is a possibility that the end side is close to the packing box, and the air guiding member may interfere with the packing box and be damaged when the vehicle is running.

Therefore, the present disclosure is a vehicle wind guide member capable of suppressing the traveling wind from below the cab from flowing above the cab back member or outside in the vehicle width direction and preventing damage due to interference with the packing box. The purpose is to provide.

In order to solve the above problems, in the first aspect of the present invention, the cab is arranged above the front parts of the left and right side members, and the packing box is mounted above the left and right side members behind the cab. A substantially U-shaped cab back member that extends upward from the left and right side members and is bridged between the left and right side members is provided below the rear part, and the rear part of the cab is supported by the cab back member from below. It is a vehicle wind guide member for guiding the traveling wind flowing downward, and includes a support portion and a plate-shaped wind guide portion. The support portion is supported by the cabback member. The wind guide extends along at least a part of the area of the cabback member above the left and right side members and projects rearward from the cabback member. At least the trailing edge of the wind guide is formed by an elastic body. The trailing edge of the wind guide is close to or in contact with the front surface of the packing box.

In the above configuration, since a substantially U-shaped cab back member is provided below the rear portion of the cab, an inner space surrounded by the cab back members above the left and right side members in rear view (hereinafter referred to as "inner space"). ), The running wind from below the cab circulates when the vehicle is running. Since the wind guide extends along at least a part of the area of the cabback member above the left and right side members and protrudes rearward from the cabback member, the outside of the cabback member (upper) from the inner space of the cabback member. Alternatively, the outflow of the traveling wind to the outside in the vehicle width direction) can be suppressed by the wind guide portion. Therefore, it is possible to prevent the traveling wind from below the cab from flowing above the cab back member or outward in the vehicle width direction.

Further, since the rear end edge of the air guide is close to or in contact with the front surface of the cargo box, the traveling wind is guided backward by the air guide and hits the front surface of the cargo box, and then the rear end of the air guide. It is possible to suppress the outflow of running wind from between the edge and the front surface of the packing box to the outside of the cabback member. Therefore, it is possible to prevent the traveling wind from below the cab from flowing above the cab back member or outward in the vehicle width direction.

As a result, for example, a heat source device such as an internal combustion engine is mounted below the cab, and in the outer region of the space between the cab and the packing box, which is not surrounded by the cab back member, the periphery of the intake port to the internal combustion engine or the like. In a vehicle in which the device is arranged, by arranging the wind guide portion at an appropriate position of the cabback member (for example, the area of the cabback member on the intake port side), the vehicle travels under the cab when the vehicle is traveling. Even if the wind flows through the inner space of the cab back member in a state where it is warmed by the heat source device and becomes hot, the outflow of the running wind to the intake port side can be suppressed, so from the intake port of the hot running wind. The suction of the air intake can be suppressed, and the rise in the intake air temperature of the internal combustion engine can be suppressed.

Further, since at least the rear end edge of the wind guide is formed by an elastic body, even if the rear end edge of the wind guide interferes with the front surface of the packing box when the vehicle is running, etc. Damage to the wind guide member due to interference can be prevented by deformation of the elastic body.

Therefore, it is possible to prevent the traveling wind from below the cab from flowing above the cab back member or outward in the vehicle width direction, and to prevent damage due to interference with the packing box.

A third aspect of the present invention is the vehicle air guiding member of the second aspect, wherein the air guiding portion has a height near the upper surface of one of the left and right side members of the cab back member. It extends continuously from the position to a height position near the upper surface of the other side member of the left and right side members.

In the above configuration, the wind guide portion continuously extends from a height position near the upper surface of one side member of the left and right side members of the cabback member to a height position near the upper surface of the other side member. For this reason, the traveling wind flowing backward through the inner space of the cabback member is suppressed from flowing out from the inner space to the outside of the cabback member (upward and outside in the vehicle width direction) by the air guide, and the air guide and the packing box. It is guided downward from between the left and right side members by the front of the.

The fourth aspect of the present invention is the wind guide member of the vehicle of the second aspect or the third aspect, and the entire area of the wind guide portion is formed by an elastic body.

In the above configuration, since the entire area of the wind guide portion is formed by the elastic body, for example, as compared with the case where only a part of the region on the trailing end edge side of the wind guide portion is formed by the elastic body, the wind guide portion Deformation in the front-back direction is greatly allowed. Therefore, damage to the air guide member due to interference with the packing box can be reliably prevented by deformation of the elastic body.
