<p>PROBLEM TO BE SOLVED: To provide an ice tray difficult to be damaged against the torsional deformation while exhibiting the high ice separating performance without requiring a large twisting torque.SOLUTION: An ice tray 2 comprises: a turn regulation part 24 asymmetrically provided at a position separating from the turn center; and a rib 27 or a large fillet 28 provided in a pin point on the side of a connection part 22, where a torsion stress is concentrated, in the vicinity of a position liable to be damaged by deformation, in which by improving the rigidity of the stress concentration zone for dispersing the twisting force applied to the ice tray 2 so as to secure both the strength and ice separating performance of the ice tray 2.</p> |
