Load input to an impact detector can be increased when a localized load is input, in comparison to when load is input to a comparatively wide region. In the vehicle side door structure 10, when a localized load is input, for example due to an impact to an outer panel 18 of a pole, or the like, to a length direction intermediate portion of an impact beam 26, via the outer panel 18, the outer panel 18 locally approaches the inner panel 20 side due to the length direction intermediate portion of the impact beam 26 bending, and a load is input to the vehicle width direction outer-edge portion of the sensing bracket 32. As a result, load is transmitted to the inner panel 20, via the horizontal section 32B and an inner-side joint section 32A of the sensing bracket 32, and also load (acceleration, displacement or the like) is input to an acceleration sensor 40 attached to the inner panel 20.
