GEAR MECHANISM, ICE MAKING DEVICE AND ASSEMBLING METHOD FOR GEAR MECHANISM

摘要

A gear mechanism may include a first gear for operating a first drive object a second gear for operating a second drive object in cooperation with the first drive object and a third gear connected with a drive source. The second gear may include a small gear part engaged with the first gear, and a large gear part engaged with the third gear. An end face of the second gear on the large gear part side may be formed with a flange part and the flange part is formed with a cutout part for allowing the large gear part to engage with the third gear. The gear mechanism may be preferably applied to an ice making device. An assembling method for the gear mechanism may utilize a previously formed mark part on the first gear for determining a position in a circumferential direction of the first gear with respect to the case body and a previously formed positioning recessed part in the small gear part of the second gear so that a positioning pin is capable of being engaged with the positioning recessed part.
