Abstract: An attachment portion between an upper member (11) and a radiator (20) is constructed so as to be displaced in a longitudinal direction of the upper member (11) when an impact force is applied to the upper member (11) by constructing a mount cushion (30) so as to be deformed easily in a longer diameter direction thereof. By this structure, when an impact force is applied to the upper member (11) from a front side of a vehicle, as it is not that the radiator (20) and the upper member (11) are deformed together but that the upper member (11) is deformed prior to the radiator (20), a bending rigidity to an impact force becomes smaller than a conventional case. Consequently, since the upper member is allowed to be deformed easily at the time of collision without largely reducing the mechanical strength of the upper member (11), compatibility between the requirements of protection of pedestrians and sufficient strength of the upper member (11) can be ensured.
