Then, at the upper position of the frame plate main body 9, a distance D is set apart from the rear plate 11 so that the external filter 7 can be inserted between the frame plate 8a and the suction grill 5 when the frame plate 8a is fixed to the suction grill 5. An insertion hole 13 is bored through which a fixing rod 15, which will be described later, can be inserted.

In addition, the lowermost part of the frame plate main body 9 is bent to the right on the opposite side of the front plate 10 and the rear plate 11 to form an oil pan 20, which will be described later.
A bend 14 is formed to prevent the material from coming off outward.

The right frame plate 8b is formed symmetrically with the left frame plate 8a.

Next, the fixing fitting 15 consists of a fixing rod 16, three sets of washers 17, and a wing nut 18. The fixing rod 16 has screws 16a and 16b installed at both ends thereof,
The insertion hole 1 of the frame plate main body 9 is located at one end (on the right side in Figure 3).
A flat washer 16b with a slightly larger diameter than 3 is inserted to the end of the screw 16a and fixed by welding to form a contact surface with the frame plate 8b, and the screw 16a at the other end (left side) Distance is external filter 7
