Abstract
A vehicle body frontal structure includes a bumper face extending in a widthwise direction of a vehicle, a bumper beam disposed behind the bumper face and extending in the widthwise direction of the vehicle; and an energy absorbing member disposed between the bumper face and the bumper beam, formed in a hollow cross sectional shape of which a rear portion is left open, and having an open edge portion that is joined to the bumper beam, so as to deform and absorb collision energy when the collision energy in a rearwards direction of the vehicle is applied to the bumper face. The open edge portion includes cutaway portions which leave portions of the open edge portion as joining leg portions to the bumper beam, and the joining leg portions are provided with deformation guide portions which, in the initial period of deformation by the collision energy, cause the open edge portion to tilt in a predetermined direction.
