Document Type and Number:
Japanese Patent JP2022186318
Kind Code:
A
Abstract:
To adjust a movable range of an input rod of an air cylinder attached after the production.SOLUTION: In a thrust force magnifying device 1, a retraction stopper 361 which contacts with a hydraulic chamber 8 side end surface of an input side lid 3 is attached to a tip of an input rod 101 as retraction restricting means for restricting retraction of the input rod 101 of an air cylinder 100 attached after production. The retraction stopper 361 is attached so that a step part (a flat part etc.) of the input rod 101 is stopped at a position located at the hydraulic chamber 8 side relative to an O ring 47 for the input rod 101 in a state that the retraction stopper 361 contacts with the input side lid 3 etc. The structure prevents the step part from interfering with the O ring 47 by advancement or retraction of the input rod 101.SELECTED DRAWING: Figure 1
