A cam mechanism may include a rotation cam body, a first moved member which is urged so as to move along an inner side cam face formed on the rotation cam body, and a second moved member which is urged so as to move along an outer side cam face formed on the rotation cam body. An end face of the rotation cam body is formed with a surrounding wall part, a protruding part protruded from the end face on an inner peripheral side so as to face the surrounding wall part and, a part of which is formed as a discontinuity portion, and a recessed part formed so as to recess from the end face in an area sandwiched between the surrounding wall part and the discontinuity portion. The inner side cam face is structured of an inner wall face of the protruding part and an inner wall portion directing to an inner side in a radial direction of the recessed part. The cam mechanism may be effectively utilized in an ice making device.
