To provide a food processor capable of not only chopping, mixing and grating vegetables but also milling tea leaves or the like by mounting an attachment having a decelerating mechanism between a rotary shaft and a rotary member.

At least two kinds of removable attachments are used for a food processor body having a driving motor and a rotary shaft. One is an attachment 4 having decelerating mechanisms 7-14 between the rotary shaft and a rotary member, and has a powder milling device as the rotary member. The other one is an attachment having a high-speed rotary member capable of transmitting the rotation of the rotary shaft of the food processor body as it is. By selectively mounting them, the rotary member can be provided with various rotational speed, so that various kinds of foods can be processed by one food processor body, that is, the chopping, mixing or grating of vegetables are performed by the high-speed rotation, and the powder milling process or the like is performed by the low-speed rotation.
