Abstract
In a method for joining bumper members, a bumper reinforcement including a rear inclined wall provided with a hole, and a bumper stay in a hollow shape are prepared. The method for joining bumper members includes the steps of: inserting the bumper stay through the hole of the bumper reinforcement to pass through the rear inclined wall; inserting rubber into the bumper stay; and compressing the rubber in a direction of an axis L of the bumper stay to expand the rubber outward from inside to expand and deform at least a portion of the bumper stay inserted into the hole, thereby joining the bumper stay to the rear inclined wall by press-fitting.
