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.

A torque limiter may include a first member provided with a circumferential face, a second member provided with a base plate part and a cylindrical drum part which is extended from the base plate part so as to surround the circumferential face of the first member, and an urging member for urging the cylindrical drum part of the second member to the circumferential face of the first member. The cylindrical drum part is formed with a plurality of cutout parts to be divided into a plurality of elastic plate parts. The cutout part is extended from a tip end of the cylindrical drum part to a middle position in a radial direction of the base plate part and the elastic plate part is formed of the cylindrical drum part and the base plate part.
