At this time, since the guide roller 18 is in position a of the guide slot 18 provided in the guide frame 16, the rotation of the rotation sleeve 17 is restrained, and the cross casing 10 is also restrained from rotation by the rotation restraint key 1.
Rotation is restricted by 0d.

これによって弁軸4の回転は、弁軸4を回転させながら

That is, the guide roller 18 is connected to the guide frame 1 in a fixed state.
If the valve shaft 4 is further rotated and lowered from this point, the guide roller 18 at position b will not be able to move downward, so the downward slope will occur. The part 19 moves along part a from position b to position C while rolling, that is, rotates downward.

As the guiding roller 18 rotates downward, the guiding roller 18
The turning sleeve 17, which is integrally attached thereto, also rotates downward as one unit.
