ABSTRACT:
A leaf switch may include a cam body formed with a plurality of cam parts in a multistage shape and a plurality of leaf contact pieces which are extended toward the cam body and whose tip end sides of the plurality of leaf contact pieces are respectively abutted with the plurality of cam parts, and base end sides of the plurality of leaf contact pieces are held at the same height position. Further, an ice making device may include a water supply leaf switch for controlling water supply from a water-supply part to an ice tray, and a water supply amount adjust mechanism which includes an operation member that causes a leaf contact piece to deform to adjust a timing when the water supply switch is turned on or off. Further, an ice making device may include an ice detecting lever and a lever position detecting mechanism which detects ice amount in an ice storage part by detecting a position of the ice detecting lever.
