<p>PURPOSE:To simplify structure by constituting a wheel hub part from a motor incorporated, thus avoiding the necessity of a feeding ring, etc. CONSTITUTION:A motor 1 and a reduction gear 2 are integrally formed and bolt-tightened onto a fixed wheel 10. The output of a motor output shaft 3 is taken-out onto an axle 8 through the gears 4 and 5 fixed onto a movable wheel 6, and a timer 12 is revolution-driven through the movable wheel. With such constitution, a feeding ring, brushes, etc. can be removed.</p> |
