A motor is provided that includes magnetic poles, an armature core, armature coils, a commutator, and power supply brushes. The armature core includes teeth arranged in the circumferential direction to extend in a radial pattern. The armature coils include inner layer coils and outer layer coils. Each of the inner layer coils is wound around radially proximal end portions of two circumferentially adjacent teeth or a radially proximal end portion of one of the teeth. The inner layer coils are arranged in the circumferential direction without overlapping each other in the radial direction. Each of the outer layer coils is wound around radially distal end portions of two circumferentially adjacent teeth by distributed winding. The outer layer coils are arranged radially outward of the inner layer coils and are arranged in the circumferential direction without overlapping each other in the radial direction. The circumferential center of the inner layer coils and the circumferential center of the outer layer coils are displaced in the circumferential direction.

A molten dielectric resin material is filled in a section of an inside of a hollow dielectric body, in which electrode wires are installed. The molten dielectric resin material is solidified to form filler resin, so that the hollow dielectric body has a sensor portion, in which the filler resin is not filled in the inside of the hollow dielectric body, and a non-sensor portion, in which the filler resin is filled in the inside of the hollow dielectric body. A power supply connector is installed to one end part of the hollow dielectric body located at the non-sensor portion side and includes a plurality of electrically conductive terminals that are electrically connected to the plurality of electrode wires.

When a drive shaft is in a non-drive state, a second drive rotor is in a non-engaged state with a driven rotor with respect to its own rotating direction. When the drive shaft is in a drive state, a rotating force of a first drive rotor is transmitted to the second drive rotor through an urging member. As a result, a power transmitting member revolves, and a centrifugal force arranges the power transmitting member at a second clamping position. The second drive rotor receives a reaction force from a driven rotor via the power transmitting member. As a result, the second drive rotor is relatively rotated in an opposite direction to a rotating direction of the first drive rotor with respect to the first drive rotor, against an urging force of the urging member. As a result, the first drive rotor is engaged with the driven rotor with respect to its own rotating direction. Accordingly, the clutch is stably operated.

An opening and closing device includes an electrically conductive fixed body, a movable body, a drive motor, a speed control device, a detection assembly, and a determining device. The electrically conductive fixed body defines an opening portion therein. The movable body is displaceable between a full closed position and a full open position. The drive motor drives the movable body to open and close the opening portion of the fixed body. The detection assembly includes a sensor electrode. The determining device computes, as a detection value, a change amount of the capacitance at the sensor electrode per a predetermined constant measuring time based on the change of the capacitance detected by the sensor electrode. The determining device compares the detection value with a constant threshold value, and determines whether the object exists between the movable body and the periphery of the opening portion based on the comparison result.
