Also, the height of the shaft insertion part 47 and the reinforcing wall part 48 are
It is lower than the peripheral wall 30 of the support plate 23.

In the above configuration, when the guide plate 24 is mounted on the back side of the front set plate 5, the support plate 23 is first fixed to the back surface of the front set plate 5 with screws 29. Next, the center pivot shaft 36 of the disk base 34 of the guide plate 24 is aligned with the shaft insertion portion 47 on the support plate 23 side, and the pair of engagement claws 37 are aligned with the claw insertion recess 50 of the reinforcing wall portion 48. Then, the disc base 34 side of the guide plate 24 is pushed forward toward the front set plate 5 side. Then, each engaging claw 37 is elastically deformed inward, and the claw portion 39 slides in the claw insertion concave portion 50,
The pivot shaft 36 is inserted into the shaft insertion portion 47.

Then, the claw portion 39 of the engagement claw 37 is inserted into the claw insertion recess 50.
, The claw portion 39 is engaged from the front side with the engaging portion 52 of the front end edge of the reinforcing wall portion 48, and the guide plate 24 can be mounted on the support plate 23. For this reason, after the support plate 23 is mounted on the back surface of the front set plate 5, the guide plate 24 can be mounted on the support plate 23 from behind, so that the guide plate 24 is mounted on the support plate 23 and mounted on the front set plate 5. The work at the time of assembly is very easy as compared with the case of performing.

In a state where the engaging claw 37 is inserted from the claw insertion concave portion 50 and assembled, the guide plate 24 is in the storage position D as shown by a virtual line in FIG.
