Abstract
An electric vehicle in which a gear shaft provided with a helical gear is held by a first casing member through a first bearing. The gear shaft has a splined outer circumferential surface fitted in a splined inner circumferential surface of a rotor shaft that is held by a second casing member through a second bearing and is held by a third casing member through a third bearing. The gear shaft includes a large diameter portion which has a diameter larger than a diameter of the splined outer circumferential surface, and the large diameter portion is in contact, at its end surface, with an end surface of an inner race of the second bearing. The rotor shaft includes a stepped portion that is spaced apart from the third bearing by a clearance that is larger than an internal clearance of the second bearing.
