Document Type and Number:
Japanese Patent JP2001124127
Kind Code:
A
Abstract:
To exercise the impact energy absorbing ability of a cylindrical member obtained by injection molding a thermoplastic resin, in maximum.
This impact energy absorbing device 1 comprises a delaminatable cylindrical member 2 obtained by injection molding a thermoplastic resin while at least partially orientated obliquely to the axial direction of the cylindrical member, and a trigger 3 having an insertion part 4 fitted to an opening end of the cylindrical member, and an enlarged part 5 integrally molded with the insertion part 4.
