ABSTRACT:

Each side guard part has a hollow reinforcing part. The hollow reinforcing part is made up of a side wall of the scroll part, an approximately horizontal guard wall formed on the side wall, and a connecting rib connecting together the guard wall and the side wall. The reinforcing part makes the cutter housing resistant to impacts from the sides and to bending with respect to its length direction.
