Claims (1)
、このパス穴の開口部の一端に、銅球を圧入して
圧油通路を形成するためのパス穴の塞において、
前記鋼球より開口部側に、外周部から内側に切り
込みを形成した皿バネを挿入したことを特徴とす
るパス穴の栓の抜け止め用装置。 In order to flow the pressure oil, a pass hole is formed in the housing, and a copper ball is press-fitted into one end of the opening of this pass hole to close the pass hole to form a pressure oil passage.
A device for preventing the stopper of a pass hole from coming off, characterized in that a disc spring having a notch formed inward from the outer periphery is inserted closer to the opening than the steel ball.
