PROBLEM TO BE SOLVED: To provide a wiring structure for a high voltage cable capable of appropriately protecting the high voltage cable not only in a case of full-flap collision but also in a case of offset collision.SOLUTION: The present invention relates to a wiring structure for a high voltage cable that is pulled from a power unit chamber which is provided at a front side of a vehicle, to a floor tunnel. The wiring structure for the high voltage cable comprises: a dash cross member 18 which is interposed between the power unit chamber and a passenger compartment and with which a tunnel entrance is formed; an on-vehicle unit which is disposed while facing the tunnel entrance in a longitudinal direction of the vehicle; and a resin protection member 32 which is fitted at a side of the dash cross member 18 facing the on-vehicle unit and forms a cable passage between the protection member and the dash cross member 18. The protection member 32 includes: a passage part 34 that is a recess; and a yield strength part 36 which is provided at both sides in a width direction of the passage part 34 and thicker than the passage part 34. An yield strength of the yield strength part 36 with respect to a compression force in the longitudinal direction of the vehicle is greater than a bending yield strength of the dash cross member 18.SELECTED DRAWING: Figure 2
【課題】フルフラップ衝突した場合だけでなく、オフセット衝突した場合でも、高電圧ケーブルを適切に保護できる高電圧ケーブルの配索構造を提供する。【解決手段】車両前方に設けられたパワーユニット室から、フロアトンネルへと引き出される高電圧ケーブルの配索構造であって、パワーユニット室と車室との間に介在し、トンネル入口が形成されたダッシュクロスメンバ18と、トンネル入口と車両前後方向に対向して配置される車載ユニットと、ダッシュクロスメンバ18のうち車載ユニットとの対向面側に取り付けられ、ダッシュクロスメンバ18との間にケーブル通路を形成する樹脂製の保護部材32と、を備え、保護部材32は、凹部である通路部34と、通路部34の幅方向両側に設けられ、通路部34より肉厚の耐力部36と、を有しており、耐力部36の車両前後方向の圧縮力に対する耐力が、ダッシュクロスメンバ18の曲げ耐力よりも大きい。【選択図】図2
