Abstract

Provided is a structure of a vehicle end section for ensuring combination stiffness at a joint which is located between a bumper reinforcement part and a structural part and at which a hook attaching part is disposed. A front vehicle body structure (10) comprises: a bumper reinforcement part (12) which has a B-shaped cross section where a concave portion (12N) opened backwards is disposed between a pair of upper and lower closed cross sections (12C); a crush box (18) disposed at a rear portion of an edge in a length direction of the bumper reinforcement part (12); a bolt (32) and a weld nut (30) which connect the upper and lower closed cross sections (12C) of the bumper reinforcement part (12) to a closed cross section of the crush box (18) in a front-back direction; and a pipe nut (34) which is fixed to the crush box (18) in the closed cross section of the crush box (18) in the front-back direction and is disposed oppositely to the concave portion (12N) for access of a hook member (40) through an access hole (38).

Description

technical field [0001] The present invention relates to a vehicle end structure provided with a bumper reinforcement. Background technique [0002] A structure is known in which a tow hook attachment portion is arranged at a junction between a bumper reinforcement and a front side member (for example, refer to JP-A-2009-292175). In this structure, it is difficult to ensure the number of joining points between the front side member and the bumper reinforcement within the closed section of the front side member. In addition, there is known a structure in which a tow hook is attached to a bumper reinforcement at a mounting portion (for example, refer to JP-A-2008-7044). Furthermore, there is known a bumper reinforcement having a "B" cross-sectional shape in which a recess is formed between upper and lower closed cross-sectional parts (for example, refer to Japanese Patent Laid-Open No. 11-245741, Japanese Patent Laid-Open No. 2000-198401, JP Japanese Patent Laid-Open No. 2009...
