[Problem] An object of the present invention is to provide a steering angle detecting apparatus for vehicles that obtains a wide range of angle information by performing vernier calculation by means of angle information from an angle sensor provided for a steering shaft and angle information from a rotation angle sensor of a motor, and detects a steering angle the neutral point of which has been specified in a short time by relatively simple structure and processing, and an electric power steering apparatus equipped therewith. [Means for solving the problem] A steering angle detecting apparatus for vehicles comprises a vernier calculating section that performs vernier calculation based on a steering shaft angle and a motor angle, a neutral period specifying section that specifies a neutral period including a neutral point based on a reference angle calculated by the vernier calculation in the vernier calculating section, and a neutral point specifying section that specifies the neutral point from the neutral period and a stored neutral point value, and outputs a steering angle the neutral point of which is specified.
