摘要

PROBLEM TO BE SOLVED: To prevent oil from leaking out even if the depressing force into an oil pressure hole of a body to be tested is greatly increased by a detecting probe. SOLUTION: An aluminum collar 16 is disposed through an O ring 18 for sealing and a pair of O rings 19 for preventing separation on an inner pipe 12 installed at the end of the detecting probe main body 3a, and a fitting section 16a is formed at the end of the aluminum collar 16 in order to be fit into and positioned in an inlet of the oil pressure hole 1a, and an O ring 17 is employed as a sealing material.
