Abstract: An electromagnetic switch is provided which includes: a coil generating magnetomotive force; a frame accommodating the coil and generating a flux path; a resin cover covering an opening of the frame; and a current-supply terminal member energizing the coil. The current-supply terminal member includes: a blade-shaped terminal whose end is connected to the coil and whose another end is drawn out of the resin cover in the axial direction of the electromagnetic switch; and a plate-shaped external connection terminal whose end is joined to an end of the blade-shaped terminal and whose another end is drawn out in the direction intersecting the axial direction. A portion between the ends of the external connection terminal is insert-molded in a terminal anchor block provided with the resin cover. A female terminal of a power supply connector provided at an electric supply line is fitted and electrically connected to the external connection terminal.

Abstract: In a starter for starting an on-vehicle engine, a solenoid is provided to push a pinion gear. The solenoid has an electromagnetic coil composed of a single coil and electrically separated from a motor circuit, a fixed core, and a plunger. Supply of excitation current to the electromagnetic coil allows the fixed core to be magnetized to attract the plunger. Hence, a movement of the plunger results in a push of the movable member toward the ring gear. A switch is provided in the circuit and has a contact, a movable core, and a switch coil functioning as an electromagnet attracting the movable core in response to supply of current to the switch coil. A movement of the movable core results in on/off switching operations of the switch. The switch is allowed to operate independently of the solenoid when both the switch and solenoid are controlled.

Abstract: An apparatus for starting an engine, including a motor, an output shaft driven by the motor, a pinion provided along the output shaft, and an electro-magnetic solenoid device. The electro-magnetic solenoid device is configured to push the pinion axially toward a ring gear of the engine to mesh the pinion with the ring gear and transfer a rotational force, which is referred to as a motor torque, generated by energization of the motor from the pinion to the ring gear, thereby starting the engine. The apparatus is configured such that, at starting of the engine in its warmed-up state, the motor torque can continue to be applied from the pinion to the ring gear until at least the second compression stroke even when an engine speed varies.

Abstract: An electromagnetic relay for starting a motor of a starter includes a resistor to reduce an activation current that flows through the motor from a battery for activation of the motor, a relay contact that causes the starting current to flow while bypassing the resistor, a relay coil that forms an electromagnet when excited by energization, and a control circuit that controls an excited state of the relay coil for activation of the motor to open or close the relay contact, thus controlling energization of the motor from the battery via the resistor. The electromagnetic relay incorporates therein the control circuit.
