<P>PROBLEM TO BE SOLVED: To provide a rotational driving force deceleration transmission mechanism capable of decelerating and transmitting the rotation of a motor shaft during a transmission process without using any relatively expensive geared motor, and accordingly, and improving cost effectiveness. <P>SOLUTION: The rotational driving force deceleration transmission mechanism includes: a shaft cylinder 15 disposed in a motor housing 10; the drive shaft of a motor extending through the inside of the shaft cylinder 15; a rotary case 16 where a rotary base board 11 is installed and which is pivotally supported by the shaft cylinder and the drive shaft via a bearing 22 into which the shaft cylinder 15 is fitted and a bearing 23 into which the tip of the drive shaft is fitted; a fixed sun gear 30 disposed at the tip of the shaft cylinder 15; rotation transmission means 26, 27 and 28 disposed between the drive shaft and the rotation shaft 19 of a round blade 14 pivotally supported at the edge of the rotary case 16; and a planetary gear 31 attached to the rotation shaft 19 engaged with the fixed sun gear 30. <P>COPYRIGHT: (C)2013,JPO&INPIT |
