Engine starter and resistor short-circuiting device

An engine starter for driving a starter motor by closing a starter switch connected in series between a power source and said starter motor for receiving power supply from said power source to start an engine, comprising:

• a resistor connected in series to said starter switch between said power source and said starter motor, for limiting a current flowing through said starter motor;
• and
• a short-circuiting switch connected in parallel to said resistor, for short-circuiting both ends of said resistor by energization of a driving coil after start of an operation of closing said starter switch,
• wherein said resistor is made of a plate-like stainless steel;
• wherein said starter switch includes an electromagnetic switch for connecting and disconnecting a first fixed contact connected to said power source and a second fixed contact connected to one end of each of said short-circuiting switch and said resistor by a moving contact driven by a driving coil and a holding coil, the driving coil having one end connected to said power source through an intermediation of a starting switch closed at a time of driving of said starter motor and another end connected to a side of the second fixed contact, the holding having one end connected to said power source through an intermediation of the starting switch and another end connected to a ground;
• and,
• wherein said short-circuiting switch includes an electromagnetic switch for connecting and disconnecting a first fixed contact connected to the second fixed contact of said starter switch, the other end of the driving coil, and the one end of said resistor and a second fixed contact connected to another end of said resistor and said starter motor by a moving contact driven by a driving coil having one end connected to an output terminal of a control section and another end connected to the ground, the control section being connected to said power source and the starting switch so as to supply electric power, which is supplied from said power source, from the output terminal after elapse of a predetermined time period from the closure of the starting switch.
