To provide a bumper rubber that can reduce a rattling sound of a door at the time of traveling of a vehicle while suppressing the reduction of an impact absorbing force at the time of closing of the door.
A bumper rubber 10 comprises an anchor part 30 attached to a door panel 7, and an impact absorbing part 20 formed of an elastic body. The impact absorbing part 20 comprises: a tip part 21b that elastically contacts with a seal face 4a of a vehicle body panel 4; a cylindrical pressure receiving part 21; a constricted part 22; an inclined connecting part 25; holes 23 opened at the pressure receiving part 21 and the constricted part 22; a groove 26 formed at the constricted part 22; and penetration holes 35 formed at the constricted part 22 and the anchor part 30. By this constitution, the inclined connecting part 25 that is formed thinner than the pressure receiving part 21 is bent and deformed while overlapping with the external face of the constricted part 22 against a compression load from the tip part 21b to the pressure receiving part 21.
