## Abstract

A vehicle body front structure includes a powertrain, a pair of side members, a suspension member, a first load transmission member and a second load transmission member. The powertrain has an engine and a continuously variable transmission that are juxtaposed to each other along the vehicle width direction. The side members are disposed on the outside of the power train in the vehicle width direction. The suspension member is disposed below the side members. The first and second load transmission members mounted to the side members and the suspension member. In the power train, the continuously variable transmission is disposed on the load-transmission-member side, and has a pair of variable speed pulleys (an input-side pulley and an output-side pulley). Thus, the load received by the first and second load transmission members can be reliably transmitted to the engine through the variable speed pulleys.

## Claims

### Claim 1

A vehicle body front structure comprising:
a power train disposed in a front portion of a vehicle and including an engine and a continuously variable transmission arranged in parallel in a vehicle width direction;
a side member disposed on an outer side of the power train in the vehicle width direction and extending in a longitudinal direction of the vehicle;
a suspension member disposed below the side member; and
a load transmission member attached to at least one of the side member and the suspension member;
the continuously variable transmission being disposed on a load transmission member side of the power train,
the continuously variable transmission includes a transmission pulley,
the load transmission member comprising a load-receiving portion that projects farther on the outer side in the vehicle width direction than a side surface of the side member or the suspension member on the outer side in the vehicle width direction, and the load-receiving portion that receives a load towards a rear of the vehicle, and a load transmission portion that is joined to the load-receiving portion and that transmits the load received by the load-receiving portion to the transmission pulley of the continuously variable transmission, and
the transmission pulley overlapping with the load transmission portion in the vehicle width direction as viewed from in front of the vehicle, and being arranged in a position overlapping in a height direction with the load transmission member as viewed from a side of the vehicle.

### Claim 2 (depends on 1)

The vehicle body front structure as recited in claim 1, wherein
the load transmission member includes a first load transmission member that is attached to the side member and a second load transmission member that is attached to the suspension member.

### Claim 3 (depends on 2)

The vehicle body front structure as recited in claim 2, wherein
a first load-receiving surface is formed on a front facing surface of the first load transmission member, a second load-receiving surface is formed on a front facing surface of the second load transmission member, and the first load-receiving surface and the second load-receiving surface are arranged to be aligned as viewed from above the vehicle.
