Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent a hose from being damaged and to improve maintenance of a mold by avoiding hanging down of the hose for feeding and discharging of a cooling liq. to a cooling liq. path in a rotor to the outside of the mold in a mold for rotational injection molding. SOLUTION: A fixed mold 50 of a pair of molds for rotational injection molding is constituted of a base plate 51 and a rotor 52, and a cooling liq. path 53 is provided in the rotor 52 and inlet and outlet holes 53A and 53B for the cooling liq. path are provided on an opposite face of the base of the rotor and on the other hand, a recessed part 60 is provided on the opposite face of the rotor on the base plate and hoses 54A and 54b for the cooling liq. for performing feeding and discharging the cooling liq. to the cooling liq. path are stored in the recessed part.
