An end portion, in the extending direction, of the connection wall includes a front part and a rear part, and each of the front and rear parts extends from an inside to an outside in the vehicle width direction. A distance between a front end of the rear part and the rear wall gradually decreases in a direction from a base end of the rear part toward a distal end thereof. The front part is provided so as to extend along the front end of the rear part.

Bumper reinforcement and method of manufacturing bumper reinforcement

There is provided a crash box comprising a pedestal portion attached to one of two members that are placed in an inward-outward direction of a vehicle; and a bottomed tubular portion integrally molded with the pedestal portion and configured to include a base end portion that is arranged to rise from the pedestal portion and an extended portion that is extended from the base end portion and that has a leading end wall which forms a bottom of the tubular portion and which is attached to the other of the two members, wherein the tubular portion is configured such that a side wall of the extended portion has a smaller thickness than a thickness of a side wall of the base end portion.

Crash box and manufacturing method of the same

An impact absorbing device includes an impact absorbing member extending in a vehicle front-rear direction; and a bumper reinforcement that extends in a vehicle width direction and is attached to a front end surface of the impact absorbing member. The bumper reinforcement includes a body portion extending in the vehicle width direction and having a length in a vehicle height direction that is smaller than a length of the impact absorbing member in the vehicle height direction, and a reinforcing portion fixed to the body portion and extending along a portion of the front end surface of the impact absorbing member, the portion being positioned above or below the body portion.

A vehicle frame member includes a first wall portion formed into a band plate shape extending in a predetermined direction, a second wall portion and a third wall portion formed into a band plate shape extending in the predetermined direction, the second wall portion and the third wall portion extending in a first direction and in a second direction, respectively, from opposite ends of the first wall portion in a width direction of the first wall portion. Respective recessed groove portions extending in the predetermined direction are formed on respective outer surfaces of the second wall portion and the third wall portion.

Vehicle frame member

A bumper reinforcement includes a body part extending in a vehicle width direction, and a terminal part, which extends in the vehicle width direction, is attached to an end part of the body part in a longitudinal direction, and is joined to the body part in a state of being superimposed on the end part of the body part. Rigidity of the end part of the body part in the longitudinal direction is lower than rigidity of a center part of the body part in the longitudinal direction.

Bumper reinforcement for vehicle

A towing hook attachment structure includes: a towing hook; a bumper reinforcement having: a first wall extending in a vehicle width direction, a wall surface of the first wall facing the vehicle cabin; and an second wall and a third wall respectively extending to the vehicle cabin side from an upper end and a lower end of the first wall; and a nut member fastening the towing hook to the bumper reinforcement. The first, second and third walls are respectively provided with a first, second and third holes. The nut member is fixed to the bumper reinforcement while extending in a vehicle height direction and being inserted in the second hole and the third hole. A tip of the towing hook is inserted in the bumper reinforcement through the through hole and is fastened to the nut member.

Towing hook attachment structure

The bumper reinforcement has a front surface flange, an upper surface web, a lower surface web, an upper lip, and a lower lip. An end of the upper surface web on the upper lip side is thicker than a center. When a collision load is applied to the front surface flange, the upper surface web extending in a direction orthogonal to the front surface flange from vicinity of an upper end of the front surface flange is deformed in an outward opened direction, and the upper lip extending downward from an extension end of the upper surface web is deformed in an inward closed direction.

Automotive bumper reinforcement

A vehicle radiator apparatus includes: a radiator main body; a grill shutter unit configured to adjust the amount of air introduced from an opening in front of the radiator main body and flowing toward the radiator main body; and an air guiding plate provided to extend in a longitudinal direction below the radiator main body and the grill shutter unit to guide the air introduced from the opening to the radiator main body, in which the grill shutter unit includes: a shutter member configured to open or close the opening of a vehicle; and a shutter support member configured to support the shutter member, and including left and right side frame portions and an upper frame portion, and lower ends of the side frame portions are assembled and attached to an upper surface portion of the air guiding plate.
