发明名称 STRIKING ENERGY ABSORBING DEVICE
摘要 PROBLEM TO BE SOLVED: To reduce weight of a striking energy absorbing device, and to stabilize/increase stable breaking stress. SOLUTION: In a striking energy absorbing device 1 having a cylindrical striking energy absorbing member 2 and a trigger 3 and having the trigger 3 having an inserting part 4 fitted to an opening part on one end of the cylindrical member 2 and an expansive width part 5 being integrally molded with the inserting part and having a diameter being larger than a diameter of the inserting part and becoming large as a distance separates from the inserting part, the trigger 3 is hollow and is made of resin, and a recess/projection is arranged at least in a part of either one surface of mutually contacting surfaces of the trigger 3 and the cylindrical member 2. The trigger 3 can have a rib 8 extending in the axial direction on the inside.
