ある。However, in the electric motor of the above-mentioned starter, the field coils are divided into those for low-speed rotation and those for rated rotation, which complicates the structure of wiring and wiring of the field coils. Further, the switch contact arranged on the side of the plunger that engages with the drive lever may be rusted by water from the drive lever side, resulting in poor conduction. Further, by disposing the switch contacts at both ends of the plunger, there is a problem that the total length of the magnet switch becomes longer and the starter becomes larger. SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a small-sized starter capable of securely and reliably engaging a pinion gear and a ring gear.

When the key switch 3 is turned on, the excitation coils 7a and 7b of the magnet switches 5a and 5b are energized, and the plungers 8a and 8b are attracted in the direction of the arrow x. The movement of the plungers 8a and 8b causes the switch operating rod 14 to move.

み合い時の衝撃力が軽減される。As the switch operating rods 14a and 14b advance, the bridging contact plate 17a bridges the fixed contacts 23 and 24a in the switch chamber 10 first. Therefore, the rated voltage of the battery 4 is applied to the motor 30 after being stepped down by the resistor 26, and the armature 32 of the motor 30 starts rotating at a low speed. The rotation of the armature 32 is reduced by the reduction mechanism 35 and transmitted to the pinion gear 38. In addition, since the battery voltage is reduced by the resistor 26 in the rotational torque of the electric motor 30, the restraining torque of the electric motor 30 at the moment when the pinion gear 38 and the ring gear 40 mesh with each other is limited to a small value, and the impact force at the time of meshing is reduced. .

させる。When the plungers 8a and 8b are further sucked, the pinion gear 38 and the ring gear 40 are securely engaged, and the switch operating rods 14a and 14b are advanced.
Following the bridging contact plate 17a, a bridging contact plate 17b bridges the fixed contacts 24b and 25. Therefore, the terminal bolt 2
The resistor 26 interposed between 1 and 22 is short-circuited, and the rated voltage of the battery 4 is directly applied to the electric motor 30. The application of the rated voltage causes the motor 30 to rotate at the rated speed and start the engine.

When the plungers 8a and 8b return, the switch operating rods 14a and 14b
a, 19b return to the bridge contact plates 17a and 1b.
7b is separated from the fixed contacts 23 and 24a and 24b and 25, and the power supply to the electric motor 30 is cut off. During this time, the drive lever 39 interlocked with the plungers 8a and 8b rotates, and the engagement between the pinion gear 38 and the ring gear 40 is released.

必要がないから、浸水により発錆して導通不良になる虞
れがない。In the embodiment described above, the closing timing of the switches 9a and 9b of the two magnet switches 5a and 5b is changed to shift the motor 30 from the low-speed rotation to the rated rotation. The pinion gear 38 and the ring gear 40 can be meshed with each other without difficulty and the wear and damage can be reduced. The two magnet switches 5a and 5b are arranged side by side in parallel, and the plunger 8
Since a and 8b are connected, the attractive force of each magnet switch can be used effectively. Further, since there is no need to arrange a switch contact on the side to which the drive lever 39 is connected, there is no risk of rusting due to water immersion and poor conduction.

利点がある。Furthermore, since the motor 30 is rotated at a low speed and a low torque by a circuit interposed with the resistor 26, the wiring and the wiring arrangement structure are not complicated. The present invention can be applied to any motor of the winding field type or the permanent magnet field type. Since the two magnet switches 5a and 5b exert the same attractive force as that of a single magnet switch, the dimension from the center of the electric motor 30 to the outside of the magnet switch is reduced as shown in FIG. There is an advantage that the starter can be downsized and its mountability on a vehicle is improved.

They are connected by a circuit with a resistor 26 interposed. Further, the terminal bolt 53 and the exciting coil 7a are connected. When the fixed contacts 56 and 57 are bridged by the bridging contact plate 17b, the resistor 26 is short-circuited and becomes the same potential, so that no current flows to the exciting coil 7a, so that the amount of current consumed by the exciting coil can be reduced.

The electrical connection and operation are substantially the same as in the first embodiment. Since each of the magnet switches 65a and 65b is an independent small one, there is an advantage that it is suitable for mass production.
