PROBLEM TO BE SOLVED: To provide a walker dummy capable of properly setting the flexibility of knees against impact force to satisfactorily imitate a human body characteristic. SOLUTION: An allowable limit member 38 is provided between femur connecting member 18 and an inferior limb connecting member 20, whereby an impact force, when large, can be temporarily moderated without continuously increasing the rigidity. Therefore, when the thin part 39 of the allowable limit member 38 is broken, a non-linear characteristic is generated. Namely, since the flexibility of the knee 16 against the impact force can be properly set to satisfactorily imitate the human body characteristic, the injured state can be precisely evaluated in more detail. Thus, since the allowable limit member 38 forms such a nonlinear characteristic as corresponds to the nonlinear area after the occurrence of an injure such as peeling or breakage of the knee ligament or the like, an experimental data in the examination state close to the knee of an actual human body leg can be gained to perform a precise evaluation.
