PROBLEM TO BE SOLVED: To perform appropriate sealing for preventing air from entering a clearance between an upper opening and a lid body even if the lid body is closed by weak force, the lid body covering the upper opening for preventing a guide passage for feeding ice pieces manufactured by an ice-making mechanism into an ice storage tank from being damaged when some ice pieces are accumulated under their saturation state in the guide passage.SOLUTION: An ice-making machinery is constructed such that the upper part of a guide passage 30 for feeding ice pieces to an ice storage tank includes an upper opening 31i for releasing the ice pieces accumulated inside it to exceed a saturation state so as to prevent a peripheral wall of the guide passage 30 from being damaged and a lid body 37 covering the upper opening 31i, and a packing 41 of type A durometer hardness of 5 to 10 is installed between a circumference of the upper opening 31i and the lid body 37. |
