Abstract: A massage device includes an outer casing, a driving mechanism and at least one massage module. The massage module includes an inclined rotary plate coupled to a main gear seat having central massage balls. When the inclined rotary plate rotates, the main gear seat and the central massage ball are driven to rotate. The main gear seat engages with a plurality of planetary gears, each of which is coupled with a massage arm. An upper end of the massage arm has a peripheral massage ball disposed thereon and a lower end of the massage arm contacts with the inclined rotary plate. A rotation of the inclined rotary plate drives massage arms and the peripheral massage balls thereon to rotate via the planetary gear as well as to move the massage arms up and down, thereby providing a massage of kneading and acupressure.
