  • Patent number: 11466917
    Abstract: In an ice making device, a frame supporting an ice tray and a drive unit has a first wall at a side of an ice detection member. Supported on the first wall is a regulation member rotatable between a first rotation position not to regulate coming down of the ice detection member and a second rotation position to regulate coming down of the ice detection member. By moving the regulation member to the second rotation position, later ice making is stopped even if ice accumulating below is not much. The regulation member includes a regulator in a circular arc form and is supported rotatably around a shaft. The regulation member as a rotary member is less liable to unexpectedly move from either of the first rotation position and the second rotation position, so that movement of the regulation member to a position not intended is suppressed.
