1. A collision detection apparatus comprising:
a bumper beam extending in a vehicle width direction;
an absorber disposed adjacent to a vehicle front side of the bumper beam;
a collision detection sensor comprising a pressure tube that extends in the vehicle width direction and is held by the absorber, the collision detection sensor being configured to output a signal corresponding to a pressure change in the pressure tube; and
a bumper cover disposed on a vehicle front side of the absorber, wherein the bumper cover comprises:
a low rigidity part disposed at a position lower than the pressure tube; and
a high rigidity part disposed at a position above the low rigidity part and comprising (i) a bending rigidity higher than a bending rigidity of the low rigidity part, and (ii) an upper end at a position higher than the pressure tube,
wherein, the bumper beam has a front panel with an upper end of the front panel extending beyond an upmost end of the absorber and a lower end of the front panel extending beyond a lowermost end of the absorber, such that the bumper beam is capable of being abut on the front panel of the bumper beam beyond the upmost end and lowermost end of the absorber under a collision load.
