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 the mount part and the flange are in contact at a contact portion, and additionally, a clearance gap is provided between the mount part and the flange, and a longitudinal axis of the shaft passes through the clearance gap;
- and
- wherein the air balance mechanism further comprises:
- at least one fixing bolt configured to fix the flange and the mount part at the contact portion at a position different from the clearance gap;
- and
- at least one adjusting bolt configured to be screwed into the mount part and through the flange and clearance gap so as to allow for posture of the shaft to be adjusted.
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 the mount part and the flange are in contact at a contact portion, and additionally, a clearance gap is provided between the mount part and the flange, and a longitudinal axis of the shaft passes through the clearance gap;
- the method comprising the steps of:
- fixing the flange and the mount part at the contact portion at a position different from the clearance gap, using at least one fixing bolt;
- and
- adjusting posture of the shaft after the fixing step, by screwing at least one adjusting bolt into the mount part and through the flange and the clearance gap.
