Abstract: A main body portion (12) of an impact absorber (10) is a three-dimensional structure formed of stiff polyurethane foam. A ratio (W2/W1) of a width W2 of a slot (30) formed in an impact surface (12A) of the main body portion (12) to a width W1 of the impact surface (12A) of the main body portion (12) is in a range from ? to ½. In consequence, when a knee area M1 of an occupant M impacts against the impact surface (12A) of the main body portion (12) of the impact absorber (10), a concentration of loading on the impact surface (12A) in an initial impact period is suppressed because the slot (30) is formed in the impact surface (12A), which is most liable to bear the load in the initial impact period, and the load is dispersed. Thus, a large breakage or significant scattering of the main body portion (12) of the impact absorber (10) in the initial impact period may be suppressed, and amounts of impact absorption energy in a middle impact period and a later impact period may be assured.
