ABSTRACT:
In a gear apparatus including first and second axles arranged perpendicular to each other within a gear housing; a spur gear is fixed to the first axle; and first and second bevel gears are fixed to the first and second axles, respectively in mesh with each other, the first bevel gear is fixed to the first axle near a first bearing; the spur gear is fixed to the first axle between the first bevel gear and a second bearing; the second bevel gear is fixed to the second axle; and the first bearing for supporting the first axle is located in the vicinity of a small-diameter side surface of the second bevel gear. Therefore, the axial length of the first axle can be shortened, load applied to the spur gear can be supported uniformly on both the ends of the first axle, and the first bearing can be sufficiently lubricated by the rotating bevel gears, thus decreasing the apparatus size and increasing the apparatus life time.
