Abstract

PURPOSE: To enable a piston to move at a constant descending stroke, by providing a partition having a bore which can be passed by a piston rod with a certain gap within a cylinder main body and fixing an O ring on the above the partition.
CONSTITUTION: A partition 9 is provided with a bore 8 which can be passed by a piston rod 1 with a certain gap within a cylinder main body A, an O ring 10 is fixed on the above the partition, and an air intake port 7 for pressing down the piston by a certain stroke is opened in a chamber formed at the upper portion of the partition 9. Thereby, when an air is forcibly sent from the air intake port 7 for pressing down the piston, the O ring is moved downward in accordance with the descent of the piston 2, so that the length of descending stroke of the piston 2 is kept constant even if the length of rising stroke of the piston 2 is varied, since the bore of the partition 9 is closed in order to prevent the action of air effecting the piston 2.
