Title:
RETRACTION MECHANISM AND DIMENSION-MEASURING DEVICE PROVIDED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2024/062965
Kind Code:
A1
Abstract:
Provided is a pneumatic-cylinder-type retraction mechanism having a cylinder and a piston that is capable of reciprocating inside the cylinder, the retraction mechanism causing the piston to reciprocate using air pressure, wherein the retraction mechanism is characterized in that a sealing means, which prevents pressurized air that operates the piston from leaking from within the cylinder, is provided to the inner periphery of the cylinder facing the outer periphery of the piston to form a stationary sealing means. The retraction mechanism can exhibit at least one effect among reducing starting resistance, improving measurement accuracy of a measuring device, and shortening measurement time.
