Power feed section structure of electric power assisting motor apparatus

A power supply unit structure of an electric power assist motor apparatus, comprising:

• a connection terminal to be connected to a coil of an electric motor for outputting an assist torque;
• and
• a power supply terminal to be connected to a control circuit unit for controlling drive of the electric motor,
• wherein the connection terminal and the power supply terminal are held by a common holding member made of a resin,
• wherein the power supply terminal comprises a press-fitting portion press-fitted into a press-fitted portion of the holding member,
• wherein the press-fitted portion of the holding member has a shape that is long in a plate width direction of the power supply terminal and short in a plate thickness direction of the power supply terminal, and
• wherein, assuming that a dimension of each of both end portions of the press-fitted portion in the plate width direction of the power supply terminal is defined as L1, a dimension of a center portion of the press-fitted portion in the plate width direction of the power supply terminal is defined as L2, and a plate thickness of the power supply terminal is defined as T, the dimension L1, the dimension L2, and the plate thickness T satisfy L2<T<L1 under a non-press-fitted state.
