Title: Inspection device for headrest return prevention mechanism

Abstract: An inspection device 1 is provided to inspect a headrest return prevention mechanism 50 that prevents return of a headrest at a position supporting the head of a seated person by moving forward at a rear collision. The headrest return prevention mechanism 50 is provided with a bracket 52 and an engagement piece 51 which can return to a normal position again after being displaced from the normal position to a fixed position. The inspection device 1 comprises a base 11, a clamp mechanism 12 that fixes the bracket 52 to the base 11, a load applying mechanism 13 that applies a load to the engagement piece 51 so as to displace it from the normal position to the fixed position, a displacement sensor 14 that measures the fixed position when the engagement piece 51 is displaced from the normal position to the fixed position, and a computer 15 that determines whether the engagement piece 51 has been displaced to a predetermined fixed position or not based on the fixed position measured by the displacement sensor 14. Thus, a defective product that is not displaced to the predetermined fixed position can be appropriately determined.
