造。 In a bumper structure in which impact energy is mainly absorbed by an absorber, the absorber is
It is composed of two layers: a first absorber to which a bumper body is attached, and a second absorber in which a cylinder part slidably supports a piston part fixed to the outer periphery of the first absorber; A hydraulic control mechanism for sliding the piston in the longitudinal direction of the vehicle body is connected to the cylinder, and a burst disk is installed that is compressed when the bumper body is moved back and breaks when the inside of the cylinder reaches a predetermined pressure. A bumper structure featuring
