Claim 1:
2. The side crash test apparatus for the center pillar of the automobile according to claim 1, wherein
the roof rail support includes a roof-rail rotation braking mechanism configured to restrain, when the striker crashes into the center pillar, translation of the roof-rail simulated part and to support the roof-rail simulated part to be rotatable about an axis thereof and allow braking of the rotation, and
the roof-rail rotation braking mechanism includes
a roof-rail rotation support member attached to an end face of the roof-rail simulated part, configured to rotate about the axis together with the roof-rail simulated part, and having an arc surface formed on at least a part of an outer face,
a roof-rail rotation shaft support configured to support a rotation center of the roof-rail rotation support member to be rotatable while restraining translation thereof,
a roof-rail rotation braking plate for which one end side is attached to the outer face of the roof-rail rotation support member and that is arranged along a tangential direction of the arc surface and, when the striker crashes into the center pillar, is extended by rotation of the roof-rail rotation support member while braking the rotation and is wound around the arc surface, and
a roof-rail rotation braking plate fixed portion configured to fix another end side of the roof-rail rotation braking plate.
