In a method for joining bumper members, a bumper reinforcement 10 including a rear inclined wall 14 provided with a hole 16, and a bumper stay 20 in a hollow shape are prepared. The method for joining bumper members includes the steps of: inserting the bumper stay 20 through the hole 16 of the bumper reinforcement 10 to pass through the rear inclined wall 14; inserting rubber 30 into the bumper stay 20; and compressing the rubber 30 in a direction of an axis L of the bumper stay 20 to expand the rubber 30 outward from inside to expand and deform at least a portion of the bumper stay 20 inserted into the hole 16, thereby joining the bumper stay 20 to the rear inclined wall 14 by press-fitting. This provides the method for joining bumper members, capable of easily joining the bumper stay 20 and the bumper reinforcement 10 to each other by press-fitting while reducing cost without being limited in shape and material.
