PROBLEM TO BE SOLVED: To provide a vehicular cushion rubber for securing good durability even under axial repeated compressive deformation while maintaining deflection load property which brings the sudden rise of low deflection load in a low displacement region or deflection load when exceeding the amount of deflection in the low displacement region. SOLUTION: The vehicular cushion rubber 1 comprises an outer periphery bored groove 25 provided in the side face of a body portion adjacent to the abutting face of a door or an engine hood abutting on a vehicle body or an opening/closing member and an abutting boss 21 formed on the outer edge of the abutting face. Herein,ϕA≥ϕB is established, whereϕA is the inner periphery diameter of the boss 21 andϕB is the inner periphery diameter of the bored groove. This construction produces superior durability while selecting a simple deflective deformation region or a compressive deformation region when axial load is applied to the boss at the front end of the body portion.
