The first recess S51 is provided, and a second recess S52 to which the second operation lever L2 is attached via the second lever housing H2 is provided at the lower rear side. The second recess S52, the second operation lever L2, and the second lever housing H2 have substantially the same structure as the first recess S51, the first operation lever L1, and the first lever housing H1, and therefore will be described below. Now, the first recess S51 and the like will be described as a representative, and the description of the second recess S52 and the like will be omitted.

  The first recess S51 is formed so as to be recessed inward in the left-right direction from the outer surface of the side cover S5, and a first attachment hole S512 penetrating in the left-right direction is formed in the bottom S511. The first lever housing H1 can be assembled to the first mounting hole S512 from the outside in the left-right direction.

  In this way, the first lever housing H1 can be assembled to the first mounting hole S512 of the side cover S5 from the outer side in the left-right direction, so that the lever can be attached to the conventional side cover mounting hole. Compared to a structure in which the housing can only be assembled from the inside in the left-right direction, the first lever housing H1 can be attached to the side cover S5 after the side cover S5 is assembled to the side frame 10, thus facilitating the mounting operation. Is possible. Supplementally, in a structure in which the lever housing can only be assembled from the inside in the left-right direction with respect to the mounting hole of the side cover as in the conventional case, after attaching the lever housing to the side frame, the operator attaches the side cover which is a large part. Therefore, since the mounting hole is mounted while being matched with the lever housing, the mounting operation becomes complicated. However, according to the structure as described above, the mounting operation can be facilitated.

  In addition, since the first mounting hole S512 is formed in the bottom S511 of the first recess S51, the flange H12 of the first lever housing H1 can be accommodated in the first recess S51. The appearance of the side cover S5 can be improved without protruding from S5.
