A press member 21 with a mounting part 21a being mounted to a flange part 18 and an L-shaped contacting part 21b for gear-locking a casing 16 is provided at two locations of a flange part 18 being provided at the body frame 12. A recessed part where the mounting part 21a is engaged while being flush with it is provided at the flange part 18, and at the same time fitting nibs 29 and 29 for fixing the mounting part 21a are provided. The press member 21 is formed in one piece with the body frame 12 while being connected via a self hinge part 27 being located at the outer edge part of the flange part 18. |
