The cover body () is installed to the space X by inserting an adjust bolt () into a ring shaped main body part (and) till abut the motor housing () tightly. An outlet () is formed as a notch on a cover body (and) to discharge the foreign substances entering into the space X between the sprocket housing () and a tip end of the cover part.
