  By the way, in a vehicle, electric wiring, a washer hose, and the like are often routed from the engine room toward the rear of the vehicle body, and securing the routing route is important in terms of layout. In this case, it is desirable to effectively use the space on the roof side that extends from the front to the rear of the vehicle body. However, the roof side rail pad disposed in the space considers shock absorption as the first, so that the electric wiring Or a washer hose is difficult to pass.

  In particular, when electrical wiring, washer hoses, etc. cut the roof side rail pad vertically, holes or notches must be formed in the vertical ribs, etc. that make up the grid, and the impact absorption capacity of the roof side rail pad The problem arises that there is no choice but to sacrifice.

  Therefore, conventionally, as shown in FIG. 9, the washer hose 111 has to be routed under the vehicle body of the vehicle 101, and the washer hose 111 becomes longer, and the work is performed due to the wiring work under the vehicle body. There was a problem that the nature was bad.

  The present invention has been made in view of the above-described problems, and the object of the present invention is shock absorption for vehicles that can be routed by vertically laying a wiring object such as a hose without impairing shock absorption. To provide a body.

In order to achieve the above object, the invention according to claim 1 is fixed to a vehicle body inner panel on the side of the vehicle and disposed between the vehicle body inner panel and the side surface of the ceiling, and includes a plurality of vertical ribs and horizontal ribs. In a vehicle shock absorber formed by forming a multistage grid opening in the vehicle width direction, at least two upper and lower grid sections are provided to engage with a long engagement hole formed in the vehicle body inner panel in the vehicle body longitudinal direction. A plurality of clamps are formed in the longitudinal direction of the vehicle body, and one of the clamps is arranged at a bending inflection point on the inner side in the vehicle width direction, and is arranged on each lateral rib of the lattice located at the inflection point. It is characterized in that a notch for passing through is formed to open toward the inside of the vehicle interior.

  The invention according to claim 2 is the invention according to claim 1, wherein among the horizontal ribs in which the notches are formed, the uppermost and lowermost horizontal ribs are arranged on the inner side in the vertical direction with respect to the left and right horizontal ribs. It is characterized by that.

  According to the first aspect of the present invention, the shock absorber can be vertically cut through the routing object such as a washer hose in the notch formed in each lateral rib of the lattice located at the inflection point of the shock absorber. The degree of freedom of arrangement of the arrangement object is increased, the arrangement object can be rationally arranged in the shortest while avoiding interference with other parts, and the workability of the arrangement can be improved.

In addition, a notch for passing the wiring body is formed at the inflection point of the shock absorber that is a receiving shape on the inner side of the vehicle body, and a clamp portion is provided outside the notch. The impact absorbing capacity, rigidity and strength are reduced by the inflection point receiving shape, and the decrease in rigidity and strength is compensated by the rigidity of the clamp part. The required shock absorption capacity, rigidity and strength are ensured in a well-balanced manner.

  According to the second aspect of the present invention, among the horizontal ribs in which the notches are formed, the uppermost and lowermost horizontal ribs are arranged on the inner side in the vertical direction with respect to the left and right horizontal ribs. Arrangements such as hoses arranged along the longitudinal direction of the bottom surface are bent at a substantially right angle, and the arrangement of the arrangements when the shock absorber is cut vertically becomes slow (the radius of curvature increases) It is possible to prevent the occurrence of problems associated with excessive bending of the search object.
