The swivel base plate is divided into a rear plate portion on the rear side thereof and a front plate portion on the front side thereof, the rear plate portion being formed of a plate thinner than the front plate portion. The rear plate portion and the front plate portion are fixedly connected to each other in such in a manner that upper surfaces thereof are flush each other. A rear portion of the front plate portion projects more rearward than the partition wall. A pair of vertical walls are formed on and project from the rear plate portion. Front portions of the pair of vertical walls project more forward than the rear plate portion and are fixedly attached to the rear portion of the front plate portion and the partition wall.
