When a primate is t restrained by a movable partition wall, friction with vertical bars of a lattice of the partition wall causing damages on roots of limbs of the primate is alleviated to reduce or solve such damages. In a primate restraint device comprising a containing body having both side surfaces, a top surface and a bottom surface, a rear surface door capable of opening and shutting the rear surface side of the containing body, and a partition wall formed movably frontward and rearward in the containing body and capable of being fixed at a desired position in the containing body, some sites among vertical bar members of the partition wall, with which roots of limbs of the primate are brought into contact while the limbs are forced to protrude frontward and restrained, are covered with protective cylinders which are rotatable with respect to the vertical bar members.
