A primate restraint device comprising: a containing body having both side surfaces, a top surface and a bottom surface; a rear surface door being provided on a rear surface side of the containing body and being capable of opening and shutting the rear surface side of the containing body by sliding up and down; a partition wall being formed movably frontward and rearward in the containing body while shutting an inside of the containing body from a front surface side and being formed fixable at a desired position inside the containing body; a pair of operation handles each comprising an upper side portion and a lower side portion extending frontward in parallel from the partition wall and a perpendicular portion connecting distal ends of the upper side portion and the lower side portion; a pair of latch members each extending frontward in parallel between the upper side portion and the lower side portion from the partition wall and having a distal end connected to the perpendicular portion; and lock devices being provided on both sides on the front surface of the containing body and fixing the latch members at desired positions; each of the partition wall and the rear surface door and the both side surfaces, the top surface and the bottom surface of the containing body being formed by assembling vertical bar members and horizontal bar members into a lattice pattern; wherein a top-portion door is provided on the top surface of the containing body, wherein this top-portion door is formed capable of being locked by a top-portion door lock device and cannot be easily opened from the inside, characterized in that some sites among the vertical bar members of the partition wall, with which roots of limbs of a primate are brought into contact while the limbs are forced to protrude frontward and restrained, being covered with protective cylinders which are rotatable with respect to the vertical bar members, wherein intervals of the lattice of this top-portion door in the front and rear direction are formed wider than intervals of the lattice on the top surface of the containing body in the front and rear direction. a containing body having both side surfaces, a top surface and a bottom surface; a rear surface door being provided on a rear surface side of the containing body and being capable of opening and shutting the rear surface side of the containing body by sliding up and down; a partition wall being formed movably frontward and rearward in the containing body while shutting an inside of the containing body from a front surface side and being formed fixable at a desired position inside the containing body; a pair of operation handles each comprising an upper side portion and a lower side portion extending frontward in parallel from the partition wall and a perpendicular portion connecting distal ends of the upper side portion and the lower side portion; a pair of latch members each extending frontward in parallel between the upper side portion and the lower side portion from the partition wall and having a distal end connected to the perpendicular portion; and lock devices being provided on both sides on the front surface of the containing body and fixing the latch members at desired positions; each of the partition wall and the rear surface door and the both side surfaces, the top surface and the bottom surface of the containing body being formed by assembling vertical bar members and horizontal bar members into a lattice pattern; wherein a top-portion door is provided on the top surface of the containing body, wherein this top-portion door is formed capable of being locked by a top-portion door lock device and cannot be easily opened from the inside, characterized in that some sites among the vertical bar members of the partition wall, with which roots of limbs of a primate are brought into contact while the limbs are forced to protrude frontward and restrained, being covered with protective cylinders which are rotatable with respect to the vertical bar members, wherein intervals of the lattice of this top-portion door in the front and rear direction are formed wider than intervals of the lattice on the top surface of the containing body in the front and rear direction.
