Abstract
PURPOSE:To cancel deviation of a rotation angle by a change in backlash of a planetary gear, by reducing the eccentricity of sub-gear relatively to the main gear. CONSTITUTION:A planetary gear consisting of a main gear (10a) and sub-gear (10b) is provided on a cam shaft 9 supporting planting arms in a rotary planter. A C-shaped spring 16 is stretched between a pin 14 of the gear (10a) and a pin 15 of the gear (10b). Although the gears (10a) and (10b) are eccentric gears, the eccentricity of the sub-gear (10b) is reduced from that of the main gear (10a) to cancel a change in backlash from a difference in eccentricity and eliminate a change in spring tension even if the gears are at a position (C) where a great backlash is caused.
