In a vehicle bumper structure, an optical fiber sensor (32) is provided on the upper portion of the front surface of a front wall portion (30A) of a front-bumper reinforcement (30). A front-bumper absorber (28) is provided before the optical fiber sensor (32) and a load transfer plate (34) is disposed between the front-bumper absorber (28) and the optical fiber sensor (32). The vertical width (B3) of the front-bumper absorber (28) and the load transfer plate (34) are greater than the vertical width (B1) of the optical fiber sensor (32), and a lower end portion (34A) of the load transfer plate (34) extends below the lower end of the optical fiber sensor (32). Accordingly, when the optical fiber sensor (32) is offset to the upper portion of the front-bumper reinforcement (30), the front-bumper absorber (28) will not topple down and the impact load is input to the optical fiber sensor (32) even if the input direction of the impact load is slightly inclined.

The vehicle bumper structure according to claim 18, wherein the vertical width of the bumper shock-absorbing member is smaller than the vertical width of the bumper reinforcing member.
The vehicle bumper structure according to claim claim 18, wherein the bumper shock-absorbing member includes a main body portion that contacts the load transfer member and an anti-toppling leg portion of a reduced thickness that extends at a side opposite the offset load-sensing unit side in a vehicle height direction toward the vehicular outside surface of the bumper reinforcing member and presses against the vehicular outside surface of the bumper reinforcing member to support the main body portion of the bumper shock-absorbing member when the load is input to the bumper shock-absorbing member.
The vehicle bumper structure according to claim 18, wherein the load-sensing unit is an elongated optical fiber sensor.
The vehicle bumper structure according to claim 18, wherein the vertical width of the bumper shock-absorbing member is substantially equal to the vertical width of the load transfer member.
A vehicle bumper structure comprising:
