A floor portion structure that serves as a right foot protecting structure has a tibia pad that is provided at a portion, where a right foot of a vehicle occupant is placed, at a dash panel of a vehicle. In a case in which the tibia pad receives compressive load from the right foot at a time of a vehicle collision, the tibia pad is deformed in a shape that is inclined downwardly to the right such that a right side portion in a vehicle transverse direction at a region of contact with the right foot becomes lower than a left side portion, or is deformed such that the left side portion in the vehicle transverse direction at the region of contact with the right foot generates greater reaction force than the right side portion.
