PURPOSE:To measure accurate strength by measuring the deformation of a car body from the position of a marker fitted movably to a bar which extends in the direction wherein a collision load is placed on a car body panel and has its end fitted to the car body panel. CONSTITUTION:One end of the bar 1 of specific length is coupled rotatably with a joint part 2 fitted to the car body panel by a shaft 2a, the marker 3 is fitted movably by sliding on the bar 1, and the free end 1a of the bar 1 abuts on the marker 3 to penetrate movably in the through hole 4a of a bracket 4 fixed to the car body. The joint part 2 is installed to penetrate the outer panel 6b of a door 6 and extends in the car room in the car width direction and the free end 1a of the bar 1 penetrates the through hole 4a of a bracket 4 fitted and fixed on the flank of the tunnel part 5a, formed on a floor panel 5, on the opposite side from the door 6 where the joint part 2 is fixed. A sheet 10 is installed on a support frame 8 coupled with a side sill 7 provided to the floor panel 5 through a sheet rail 9 and a dummy 11 for a collision test is mounted on the sheet 10. |
