PURPOSE: A deceleration apparatus having a self-mating function using synchronization of gears is provided to output decelerated rotation power through a carrier, by forming an additionally added idle gear. CONSTITUTION: An input shaft(10) comprises an insertion groove(12) and a ball groove(14). A fixing groove(16) is formed in one side of the ball groove. A slide shaft(20) is installed in the insertion groove. The slide shaft is combined to the ball groove through a ball(90). A sun gear(30) is formed in a body with the slide shaft. A number of planetary gears(40) rotate as going in gear around the sun gear. A number of idle gears(50) rotate as going in gear with the sun gear and the planetary gear. A stationary ring gear(60) inscribes with the planetary gear and goes in gear with the planetary gear to decelerate rotation power. A carrier(70) has a supporting part(72). The supporting part supports the planetary gears and the idle gears. The carrier has an accommodation groove(74). The accommodation groove comprises a compressed spring(100) and a washer(110). An output shaft(80) is formed in a body with the carrier, and outputs decelerated rotation power of the planetary gear.
