A door moving apparatus includes a motor unit, a first gear, a second gear, an endless belt, a drum, and a rotator. The first gear is mounted on a rotary shaft of the motor unit. The second gear includes a diameter larger than a diameter of the first gear and teeth more than the first gear. The endless belt passes over the first gear and the second gear. A rotary power of the second gear is transmitted to the drum via a rotary power transmission mechanism. The rotator is configured to reduce a separation of the endless belt from a preset running path.

A stator of a brushless motor includes: a stator core; a coil that is formed by winding a conducting wire around the stator core; a connecting terminal that is electrically connected to an end portion of the coil; and a terminal fixing base that has an electrical insulation property, is attached to an end portion of the stator core on one side in an axial direction thereof, and fixes the connecting terminal. The connecting terminal includes a fixing portion that is fixed to the terminal fixing base, an outward projecting portion that extends from the fixing portion toward outside in a radial direction than the stator core, and a joining portion that overlaps with the outward projecting portion in the axial direction and is positioned outside the stator core in the radial direction. The joining portion is opened outward in the radial direction.

A current sensor includes at least three bus bars made of flat-plate-shaped conductors and an inverter, a plurality of cores in which a core is formed by stacking flat plates made of U-shaped magnetic bodies, and a detecting element arranged on the side of an opening portion of each of the cores for detecting the intensity of a magnetic field. An interval between the core and another bus bar that is adjacent to the bus bar inserted into the U groove of the core is &#xbd; of the length of the opening portion in the spacing direction, and the tolerance of the gap is set to a value obtained by subtracting the value of 3/2 of the length of the opening portion in the spacing direction from the value of the interval between the bus bars that are adjacent to each other, with the gap as a median value.
