PROBLEM TO BE SOLVED: To provide a stepless speed variator capable of supplying a sufficient amount of lubricant to a planetary transmission part.SOLUTION: A stepless speed variator has a planetary transmission part 50 including a sun gear 52 integrally rotated with a rotating support shaft 51, several planetary gears 53 arranged along an outer periphery of the sun gear 52 while being engaged with the sun gear 52, a ring gear 55 arranged over outer peripheries of several planetary gears 53 while being engaged with the planetary gears 53, and a carrier 54 supporting the planetary gears 53 so as to be revolved while rotating around the sun gear 52. The transmission case stores lubricant oil for lubricating the planetary transmission part 50 while its oil surface is kept less than a rotating axis height of the rotating support shaft 51. There is provided a supply part capable of supplying lubricant oil to the planetary gears 53.SELECTED DRAWING: Figure 9 |
