1. A door impact beam for a vehicle comprising:
a beam main body; and
an attaching portion provided on the beam main body and attached to a component of a vehicle door;
wherein the attaching portion includes first and second brackets and the first and second brackets are arranged to be at least partly superimposed on each other,
the first bracket is coupled to the second bracket by a coupling portion to enable absorbing a relative movement due to difference in thermal expansion between the beam main body and the components of the vehicle door,
a first locking hole is bored in one of the first and second brackets and a second locking hole is bored in the other bracket,
the first and second locking holes are adapted to be locked by a temporarily fixing member at a normal temperature and the temporarily fixing member is adapted to be softened at a predetermined temperature or higher,
and the second locking hole includes an engaging hole adapted to be engaged with the temporarily fixing member at a normal temperature and a slit which communicates with the engaging hole, extends from the engaging hole, and is smaller in width than the maximum inner diameter of the engaging hole.
