Claims

[Scope of utility model registration request]

To buffer the impact load applied to the rear end of the vehicle (in the vehicle rear bumper structure provided, the base end is provided below and along the frame provided along the longitudinal direction of the vehicle). It has a rear bumper which is pivotally supported so as to rotate the whole frame downward, and whose tip part extends to the rear end of the vehicle and receives the impact load, and the rear bumper is positioned below the frame (tilted and bent). a buffer member bent so that the bending point is in contact with a lower part of the frame and a portion connecting the bending point and the pivot point is located below the frame; and the bending point and the rear bumper. and a guide member for rotating the inclined shock absorbing member connecting the frame downward using the bending point as a fulcrum. The structure is configured such that the force is dispersed into a component force that causes the downward rotation, and is buffered by the frictional force at the bending point, the repulsive force of the bent buffer member, and the push-down blade of the tilted buffer member that is rotated. A rear bumper for a vehicle that is characterized by:
