Abstract
An impact absorbing member is formed by bending one sheet of a metal plate material and then joining adjacent end parts thereof. The impact absorbing member includes the following integrally-connected portions: a fixing plate, an impact absorbing part having two first side wall plates and two second side wall plates, two flange plates, and two bridge plates. The impact absorbing part overall has an approximate square or rectangular tube shape after being bent. Joining parts are provided at each opposing end parts of the first and second side wall plates. The adjacent end parts of the first and second side wall plates overlap and are joined. The end parts of the two flange plates are also joined to the end parts of the two bridge plates.
