- the 2nd connection part 60B is arrange
- the front wheel 12 that has moved to the rear side of the vehicle at the time of the minute lap collision hits the second connecting portion 60B, so that the second connecting portion 60B receives the collision load and applies the collision load to the front pillar 30 that is a skeleton member of the vehicle body. Can be transmitted. Therefore, peeling of the joint portion 52 between the front pillar 30 and the dash panel 50 can be further suppressed.
- a recess 86 is formed in the front spacer 80 of the spacer 60, and the recess 86 is formed in a substantially V shape opened to the front side of the vehicle in a side view. For this reason, the front wheel 12 that has moved to the rear side of the vehicle at the time of the minute lap collision can be applied at, for example, two portions of the inclined surface 86A and the inclined surface 86B of the recess 86. Thereby, the collision load input from the front wheel 12 to the spacer 60 can be dispersed.
- the spacer 60 is fastened and fixed to the rocker inner R / F 26 of the rocker 20, the bulk 40 and the gusset 42 of the front pillar 30, and the torque box inner R / F 58 of the torque box 54 with the bolts B. .
- bonding force with the vehicle in the spacer 60 is securable.
- the spacer 60 is fastened and fixed to the rocker inner R / F 26, the bulk 40, and the gusset 42, the collision load input to the spacer 60 at the time of a minute lap collision is generated in the rocker 20 and the front pillar 30 that form the skeleton of the vehicle body. Can be distributed.
- the spacer 60 is integrally formed with a protruding portion 76 that is open to the rear side of the vehicle in plan view.
- the protrusion part 76 is comprised like a vertical bead, the intensity
- a joint 56 between the rocker 20 and the torque box 54 is disposed in the protrusion 76. For this reason, since the front wheel 12 hits the projecting portion 76 whose strength has been increased, peeling of the joint portion 56 between the rocker 20 and the torque box 54 can be further suppressed, and consequently, the joint portion 52 between the front pillar 30 and the dash panel 50 can be prevented. Peeling can be effectively suppressed.
- the front wheel 12 that moves toward the vehicle rear side at the time of a minute lap collision can be applied to the spacer 60 at an early stage.
- the front wheel 12 can be applied to the spacer 60 in a state where the inclination of the front wheel 12 with respect to the longitudinal direction of the rocker 20 in plan view is reduced. This will be described below.
- the front wheel 12 When the front wheel 12 moves to the rear side of the vehicle, the front wheel 12 may be tilted with respect to the rocker 20 by a collision body. If the spacer 60 is omitted, the distance until the front wheel 12 comes into contact with the rocker 20 becomes longer, so that the inclination of the front wheel 12 with respect to the longitudinal direction of the rocker 20 when the front wheel 12 comes into contact with the rocker 20 may increase. On the other hand, by providing the spacer 60 on the vehicle front side of the rocker 20, the distance until the front wheel 12 hits the rocker 20 can be shortened. Thereby, the inclination of the front wheel 12 with respect to the longitudinal direction of the rocker 20 when the front wheel 12 hits the rocker 20 can be made small.
- the collision load can be efficiently transmitted from the front wheel 12 to the rocker 20. Furthermore, since the inclination of the front wheel 12 with respect to the longitudinal direction of the rocker 20 can be reduced, intrusion of the front wheel 12 into the vehicle width direction inside can be suppressed when the rear portion of the front wheel 12 is inclined inward in the vehicle width direction in plan view.
- the spacer 60 is fastened and fixed to the vehicle body at five locations.
- the fastening and fixing location of the spacer 60 can be arbitrarily set.
- the upper part of the rear spacer 62 may be bent toward the vehicle rear side and fastened together with the door hinge bracket 90.
- the rear spacer 62 and the door hinge bracket 90 may be integrally formed.
- the inclined surface 86A and the inclined surface 86B of the concave portion 86 are linearly inclined, but the inclined surface 86A and the inclined surface 86B of the concave portion 86 may be inclined in a curved shape.
