Abstract
A side crash test apparatus uses a crash test structure including a center pillar, a roof-rail simulated part, and a rocker simulated part, and includes: a striker; a roof rail support; and a rocker support. The rocker support includes a rocker-rotation braking mechanism configured to restrain translation of the rocker simulated part, and support the rocker simulated part to be rotatable about an axis thereof and allow braking of the rotation. The rocker-rotation braking mechanism includes a rocker-rotation support member configured to rotate about the axis together with the rocker simulated part, a rocker-rotation shaft support configured to support a rotation center of the rocker-rotation support member, a rocker-rotation braking plate extended by rotation of the rocker-rotation support member while braking the rotation when the striker crashes into the center pillar, and a rocker rotation braking plate fixed portion configured to fix another end side of the rocker-rotation braking plate.
