  On the other hand, an engaging groove 32 extending forward from the rear end of the mounting base 8 is formed at the rear end of the mounting base 8 as shown in FIG. The engagement groove 32 is cut in parallel to the front side of the mounting base 8 to form a support groove 32B, and the guide groove that extends continuously in the rear direction of the mounting base 8 after the support groove 32B. 32A is formed. That is, the engagement groove 32 is provided at the substantially central portion of the rear end of the mounting base 8, and the guide groove 32 </ b> A is expanded toward the back direction of the machine room 2. The guide groove 32A guides a stopper 38, which will be described later, into the engagement groove 32 (inside the support groove 32B) for easy insertion. The engaging groove 32 is not limited to the substantially central portion of the rear end of the mounting base 8, and the engaging groove 32 may be provided at a location other than the center as long as it is the rear end of the mounting base 8. In this case, it is needless to say that the stopper 38 must be provided at a position where it can be smoothly inserted into the engagement groove 32 (inside the support groove 32B).

  Further, the left and right sides 53B below the frame 52 are formed of steel plates and provided with stoppers 38 that can be inserted into the engaging grooves 32. The stopper 38 includes an insertion piece 41, a holding part 40 provided continuously at the upper end of the insertion piece 41, and a fixed piece 42 provided continuously at the lower end of the insertion piece 41. The insertion piece 41 is configured to be insertable into the engagement groove 32 (support groove 32B). Further, the holding portion 40 is bent at a substantially right angle at the upper end of the insertion piece 41 and is positioned on the upper surface side of the mounting base 8 so as to abut or approach the upper surface of the mounting base 8 to prevent the mounting base 8 from floating. The fixing piece 42 is bent at a substantially right angle at the lower end of the insertion piece 41 on the side opposite to the holding portion 40 and is brought into contact with the frame 52 and fixed.

  That is, the stopper 38 has an insertion piece 41 formed substantially at the center of a vertically long and substantially rectangular steel plate, and is continuously bent on one side of the insertion piece 41 at a substantially right angle, and the fixing piece 42 is continued on the other side. The holding part 40 is formed by being bent at substantially right angles, and the fixing piece 42 and the holding part 40 are bent on the opposite sides around the insertion piece 41 (FIG. 9). In addition, 43 is a detent and is provided on one side of the fixed piece 42 (in this case, the back direction of the machine room 2). The rotation stopper 43 abuts against the frame 52 and prevents the stopper 38 from rotating when the stopper 38 is fixed with a screw 45 described later.

  Then, the fixed piece 42 is placed on the frame 52, and the stopper 38 is fixed to the frame 52 with a screw 45 through a screw hole (not shown) provided in the fixed piece 42. At this time, the stopper 38 is fixed at the position of the frame 52 where the insertion piece 41 can be inserted in the approximate center of the engagement groove 32 (support groove 32B) provided in the mounting base 8. Note that a slope that is inclined in a direction away from the mounting base 8 may be provided in the forward direction of the machine room 2 of the holding portion 40. In this case, when the stopper 38 is inserted into the engagement groove 32 of the mounting base 8, it is possible to prevent the tip of the mounting base 8 from being caught and to smoothly insert the stopper. 8 The upper surface can be brought into contact with no gap. Thereby, it is possible to reliably prevent vibration due to the lifting of the rear end portion of the mounting base 8.

  Then, both sides of the rear end (front end in the insertion direction) of the mounting base 8 are placed on the front part of the rail 36, and the mounting base 8 is moved along the rail 36 in the depth direction of the machine room 2. A stopper 38 (insertion piece 41) is inserted into the engagement groove 32 provided at the (front end in the insertion direction). As a result, the mounting base 8 is held by both rails 36. Next, the front end (rear end in the insertion direction) of the mounting base 8 is fixed to the left and right sides 53B on the front lower side of the frame 52 with screws 8A (shown in FIG. 4). At this time, since the engaging groove 32 is provided with a guide groove 32A that expands in the rear direction of the mounting base 8, the insertion piece 41 is guided by the guide groove 32A and easily engaged with the engaging groove 32 (supporting groove 32B). Can enter. As a result, the restraining portion 40 of the stopper 38 abuts or approaches the upper surface of the mounting base 8, so that the lifting of the rear end of the mounting base 8 can be prevented by the restraining portion 40. Can be effectively suppressed.

  Further, the holding part 8 can be brought into contact with or close to the upper surface of the front end of the mounting base 8 in the insertion direction only by moving the mounting base 8 along the rail 36 in the depth direction of the machine room 2. Furthermore, since the engaging groove 32 (guide groove 32A) provided in the mounting base 8 is expanded toward the back direction of the machine room 2, when the mounting base 8 is inserted along the rail 36, The stopper 38 (insertion piece 41) can smoothly enter the engagement groove 32 without being caught by the end of the mounting base 8. Thereby, since the troublesome screwing work as in the prior art is eliminated, the installation work of the mounting base 8 can be easily performed, and the mounting workability can be greatly improved.
