ABSTRACT:
A hollow frame member of an aluminum alloy for a vehicle body frame includes a front pipe portion. The front pipe portion has an annular end surface as a surface receiving a collision load at a front end thereof. In the front pipe portion, a cross sectional area is gradually increased from a base end toward the receiving surface, and a thickness is gradually decreased from the base end toward the receiving surface. Thus, the front pipe portion can be crushed early and stably from the receiving surface upon collision of the vehicle to enhance the collision energy absorbing efficiency.
