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 10 comprising a containing body 20 having both side surfaces, a top surface and a bottom surface, a rear surface door 50 capable of opening and shutting the rear surface side of the containing body 20, and a partition wall 30 formed movably frontward and rearward in the containing body 20 and capable of being fixed at a desired position in the containing body 20, some sites among vertical bar members 31 of the partition wall 30, 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 33 which are rotatable with respect to the vertical bar members 31.
