本発明では、ケース上板とケース下板の接続を、前側補強材の凹部内において螺子で固定するようにしたので（より具体的には、前記ケース上板の前記第１垂直片、前記ケース下板の前記第２垂直片を、前記凹部の前記底辺に重ねて螺子で固定することで）、外部から螺子が見えにくく、意匠性が良好である。 In the present invention, the connection between the case upper plate and the case lower plate is fixed with a screw in the concave portion of the front side reinforcement (more specifically, the first vertical piece of the case upper plate, the case) By overlapping the second vertical piece of the lower plate on the bottom side of the recess and fixing it with a screw), the screw is difficult to see from the outside, and the design is good.

ケース下板の前面の上端の下側連結片は、第２垂直片が前記凹部の底側に位置するように前記凹部内に設けられるので、ケース下板の前面の上端側の重心が当該前面よりも後方側となり、ケース下板の前面の上端の下側連結片を固定しない状態であっても、ケース下面の前側への回動が抑制される。特に、ケース下板の上端側の垂直片を、ケース上板の下端側の垂直片と前側補強材の底辺間に挟まれた状態とすることで、ケース下板の上端側が仮固定され、この仮固定状態で正面から螺子を締めて固定すればよいので、作業性が良好である。 The lower connection piece at the upper end of the front surface of the case lower plate is provided in the recess such that the second vertical piece is located on the bottom side of the recess, so the center of gravity at the upper end of the front surface of the case lower plate is the front surface Even when the lower connection piece at the upper end of the front surface of the case lower plate is not fixed, the rotation of the lower surface of the case to the front side is suppressed. In particular, the upper end side of the case lower plate is temporarily fixed by setting the vertical piece on the upper end side of the case lower plate between the vertical piece on the lower end side of the case upper plate and the bottom side of the front reinforcement. Workability is good because the screw may be tightened and fixed from the front in the temporarily fixed state.
