Abstract:
1. A power transmission device comprising: a turning body and a transmission shaft being supported at a housing so as to be relatively coaxially rotatable; one shaft of an input shaft and an output shaft being connected to said transmission shaft; a first sun gear being fixed on said transmission shaft; a first planetary gear meshing with said first sun gear, said first planetary gear being supported at a rotating body; a second sun gear being fixed on said housing; a second planetary gear meshing with said second sun gear, said second planetary gear being supported at said turning body; a first inner gear meshing with said first planetary gear and a second inner gear meshing with said second planetary gear, said first and second inner gears being corotatably connected to each other; the other shaft of said input shaft and said output shaft being connected to said rotating body; and a rotating shaft being generally perpendicularly connected to said other shaft through a change-direction transmission member, wherein said rotating shaft and said other shaft are supported at an integral turning member which turns integrally with said turning body.
