The present invention relates to an ice maker for making ice which is installed within a refrigerator. In the ice maker 30 of the present invention, one end of an ice-making container 34 is supported by a frame 32, while the other end thereof is supported by a case 51 of a drive unit 50. The ice-making container 34 is made of metal, and a ground terminal 80 is electrically connected with the ice-making container 34 by a screw 75 for fastening the ice-making container 34 to the case 51, thereby establishing grounding therebeween. The ice maker is provided with a front face plate 42 for connecting the frame 32 and the drive unit 50 in the longitudinal direction along one side of the ice-making container 34. The front face plate 42 is formed with cold air passing-holes for guiding cold air within a freezing chamber of the refrigerator to the ice-making container 34. The cold air passing-holes 45 are provided with louvers 47 for more smoothly guiding the cold air to the air passing-holes, respectively. The drive unit 50 includes a drive lever 56 for driving an ice-sensing lever 60 therein, and a cam follower 57 of the drive lever 56 and a cam 55 of a rotary member 54 are interlocked with each other. The cam 55 is constructed such that a downstream portion 55d thereof is declined toward an outer periphery of the rotary member 54, and is continuously and smoothly connected with the outer periphery.

1. An ice maker for a refrigerator, comprising: a frame; an ice-making container with one side thereof supported by the frame in which ice is formed by cold air within a freezing chamber of the refrigerator; an ice-releasing lever for separating the formed ice from the ice-making container and then transferring it to a storage container; a drive unit for providing power for driving of the ice-releasing lever and supporting the other side of the ice-making container; a front face plate extending lengthily in the longitudinal direction of the ice-making container so as to connect between the frame and the drive unit; and cold air passing-holes formed at a predetermined interval in the front face plate for transferring the cold air from the exterior of the front face plate into the interior of the ice-making container. 2. The ice maker as claimed in claim 1, wherein the cold air passing-holes are provided with louvers that are open in a direction opposite to a flow direction of the cold air flowing along the front face plate, respectively. 3. The ice maker as claimed in claim 1, further comprising an ice-sensing lever driven by the drive unit for sensing the amount of ice contained within the storage container. 4. The ice maker as claimed in claim 3, wherein the drive unit comprises a case for defining an outer appearance of the drive unit, a support plate installed within the case, a drive motor installed in the support plate, a rotary member capable of being rotated by receiving the driving force from the drive motor and driving the ice-releasing lever, and a drive member for driving the ice-sensing lever while being rotated by receiving the driving force from the drive motor through a cam of the rotary member. 5. The ice maker as claimed in claim 4, wherein the cam of the rotary member is constructed such that a downstream portion thereof is declined toward an outer periphery of the rotary member to be continuously and smoothly connected with the outer periphery of the rotary member. 6. The ice maker as claimed in claim 1, wherein one end of the ice-making container is fastened to the case by a screw that is fastened within the case of the drive unit, and a ground terminal for grounding electrical components of the drive unit is connected to the screw. 7. The ice maker as claimed in claim 6, wherein the case is formed with a fastening hole through which the screw penetrates, and a rib having an inner diameter adapted to receive the screw and the ground terminal protrudes from an edge of the fastening hole.
