Abstract
The drive apparatus includes a motor, a plurality of substrates, a connector, and a connection terminal. The substrates are provided in one side of the motor in its axial direction. The connector is provided at an opposite side of the motor across the substrates in the axial direction. The connection terminal is connected to the substrates. The substrates are arranged such that a part of the substrates are overlapped when the substrates are projected in the axial direction. An overlapped region is defined as a region where the part of the substrates are overlapped. The connection terminal penetrates, in the overlapped region, at least a part of the substrates, the connection terminal being connected to the substrates in the overlapped region.
Claims15
