Helical gear device
A helical gear device includes: first and second helical gear respectively and rotatably disposed about first and third mutually parallel axes; a second helical gear meshing with the first and third helical gears so that a rotary motion is transmitted from the first to the third helical gear through the second, the second helical gear having a center bore; a support shaft disposed coaxially with a second axis parallel to the first, and extending through the center bore with a predetermined amount of radial play between the support shaft and the second helical gear, rotatably supporting the second helical gear. The second and third helical gears have a predetermined radial clearance in their reference meshing state in which their pitch circles contact. The radial clearance is smaller than a radial gap of a backlash between the second and third helical gears in the reference meshing state.
