である。In the conventional waterproofing device as described above, the oil seal 8 is damaged due to the breathing effect of the outside air due to vibration and temperature rise and fall of the electric motor.
There was a problem in that outside wood could enter through the gap created between the lip 8a and the pinion ffi 3. In particular, if the starting J motor is installed with the pinion teeth 3a and 1 facing upward or with #4 inclined upwards, there is a high risk that water will collect at the outer end of the oil seal 8 and seep into the machine. This invention was made to solve these problems, and is a waterproof starter motor that prevents water spray from entering the bearing part of the front bracket from the outside and eliminates accidents caused by moisture inside the motor. [Means for Solving the Problem] The waterproof bag d for a starter motor according to the present invention has an annular groove provided on the outer periphery of the pinion moving cylinder in the invention of claim 1. A blocking ring made of an elastic material is fitted into this groove and fixed, so that when the pinion moving cylinder is in the retracted return position, the disc-shaped portion of the blocking ring covers the front of the lip of the oil seal.
