Abstract
A water draining device 18 for a starter motor, adapted to be attached to the starter casing or bracket 4, has a tubular body 18b whose inner circumferential surface is of labyrinth structure and which is made of an elastic material. A root portion 18c of the tubular body is thinner and more deformable than the rest of the tubular body such that it bends upon external water impact to prevent invasion thereof.
