Abstract
An impact absorbing mechanism for absorbing an impact load input between receiving portions at a predetermined distance from each other is provided; in the impact absorbing mechanism, a dispersing transferring portion for dispersing and transferring the input impact load in two directions is formed by connecting respective one end sides of two load transferring members, impact absorbing members for absorbing dispersed impact loads in directions along the transferring members and supported by receiving stopping portions are disposed on the other end sides of the respective load transferring members, a connecting portion of the load transferring members is positioned to be closer to load input sides than to the other end sides of the respective load transferring members, and the input impact load is dispersed and absorbed in two directions; thereby, it is possible to obtain an impact absorbing mechanism by which impact energy absorbing performance in a displacement initial stage is enhanced to carry out efficient impact absorption and it is possible to relatively easily cope with changes in required impact absorbing properties.
