In a crank-type vehicle power transmission apparatus, since an outer member of a one-way clutch has a large swing angular velocity when an amount of eccentricity of an input side fulcrum is large and a small swing angular velocity when the amount of eccentricity of the input side fulcrum is small, a projection fixed to the outer member is detected by a proximity sensor, the swing angular velocity of the outer member is calculated from a time gap of detection signals outputted by the proximity sensor, and the amount of eccentricity of the input side fulcrum can be estimated based on the swing angular velocity. Since the cumulative value of the detection signals is not used in the course of estimating the amount of eccentricity, the occurrence of error in estimation due to an accumulation of errors can be avoided. |
