Vehicle front portion structure provided with a pedestrian collision detection sensor

A vehicle front portion structure provided with a pedestrian collision detection sensor, the vehicle front portion structure comprising:

• a bumper reinforcement disposed at a vehicle front end portion side such that a longitudinal direction of the bumper reinforcement is aligned with a vehicle transverse direction;
• a pedestrian collision detection sensor comprising a pressure tube and a pressure sensor outputting signals based on pressure changes in the pressure tube, the pressure tube comprising:
• a main tube disposed at a vehicle front side of the bumper reinforcement and extending along the bumper reinforcement from one end portion in the longitudinal direction of the bumper reinforcement to another end portion in the longitudinal direction thereof;
• and a pair of outer side tubes provided continuously with the main tube and, as viewed from a vehicle front-rear direction, extending respectively towards a vehicle lower side from positions of the one end portion and the other end portion of the main tube;
• and
• an absorber disposed at the vehicle front side of the bumper reinforcement such that a longitudinal direction of the absorber is aligned with the vehicle transverse direction, the absorber covering the bumper reinforcement and the pressure tube from the vehicle front side, and comprising a holding groove portion holding the main tube and portions of the outer side tubes at a vehicle upper side, and, in the absorber, a predetermined range overlapping with portions of the outer side tubes at the vehicle lower side as viewed from the vehicle front-rear direction is separated in the vehicle front-rear direction from the portions of the outer side tubes at the vehicle lower side.
