Abstract

An underrun protector mounting structure (3) comprises a chassis frame (4), an underrun protector (5) disposed at the front or rear of the chassis frame (4) and extending in the lateral direction of a vehicle, a bracket (6) for securing the underrun protector (5) to the chassis frame (4), and a support part (7) interposed between the front underrun-protector (5) and the bracket (6). The support part (7) includes a first plate (31) disposed on the underrun protector (5) side and a second plate part (32) disposed on the bracket (6) side of the first plate (31). The first plate (31) is formed wider than the second plate (32) in the lateral direction of the vehicle. The first plate part (31) and the second plate part (32) are stacked on each other like a leaf spring in the longitudinal direction of the vehicle.

Description

technical field [0001] The present invention relates to an underrun protector installation structure provided at the front or rear of a vehicle body frame. Background technique [0002] When a vehicle with a low vehicle height (hereinafter referred to as a small vehicle) such as a passenger car and a vehicle with a high vehicle height (hereinafter referred to as a large vehicle) such as a truck collide frontally or rearwardly, the small vehicle enters under the bottom of the large vehicle. In order to prevent such unsuitability, it is known that a large vehicle is provided with an underrun protector at its front or rear. Examples of the underrun protector mounting structure of a vehicle including the above-described underrun protector include those described in Patent Documents 1 to 3. [0003] According to the underrun protector mounting structure for a vehicle disclosed in Patent Document 1, since the underrun protector main body has a closed cross-sectional structure, hi...
