Abstract
An air balance mechanism includes a plate part, fixed shafts, and movable cylinders. A flange is provided at one end of each of the fixed shafts. The movable cylinders are movable relative to the fixed shafts. A space is formed below a lower surface of the flange. Further, the air balance mechanism includes fixing bolts and adjusting bolts. The fixing bolts fix the flange and a plate part at positions different from the space. The adjusting bolts are inserted into the plate part through the space for allowing the postures of the fixed shafts to be adjustable.

An air balance mechanism comprising:
- a mount part;
- a shaft provided with a flange at one end thereof, the flange being fixed to the mount part;
- and
- a cylinder configured to cover the shaft, and
- configured to be movable relative to the shaft;
- wherein a clearance is provided at a contact portion of at least one of the mount part and the flange;
- and
- wherein the air balance mechanism further comprises:
- at least one fixing bolt configured to fix the flange and the mount part at a position different from the clearance;
- and
- at least one adjusting bolt configured to be screwed into the mount part through the flange at a position overlapped with the clearance for allowing posture of the shaft to be adjustable.
A method of adjusting posture of an air balance mechanism, the air balance mechanism comprising:
- a mount part;
- a shaft provided with a flange at one end thereof, the flange being fixed to the mount part;
- a cylinder configured to cover the shaft, and configured to be movable relative to the shaft;
- wherein a clearance is provided at a contact portion of at least one of the mount part and the flange;
- the method comprising the steps of:
- fixing the flange and the mount part at a position different from the clearance using at least one fixing bolt;
- and
- adjusting the posture of the shaft after the fixing step, by screwing at least one adjusting bolt into the mount part through the flange at a position different from the clearance.
