  • Patent number: 10358167
    Abstract: A vehicle front structure includes a radiator support upper, a first connection member and a second connection member. The radiator support upper is provided with a connected portion on an inner side with respect to both ends of the radiator support upper in a vehicle width direction. When viewed in a vehicle longitudinal direction, the first connection member connects the connected portion with a bumper reinforcement in an oblique direction such that a portion of the first connection member, connected to the connected portion, is located on an inner side in the vehicle width direction with respect to a portion of the first connection member, connected to the bumper reinforcement. The second connection member connects the radiator support upper with a vehicle component. A portion of the second connection member, connected to the radiator support upper, is located on a central axis of the first connection member.
