におけるラッシュ調整装置。An axial cylinder hole that opens into the introduction chamber is formed inside the cylindrical tappet body, which has a hydraulic oil introduction chamber formed at the upper end of the seal where the cam slides. A plunger is inserted into the plunger and its lower end side is operatively connected to an intake or exhaust valve, and the inside of the plunger is divided into two upper and lower chambers and is provided with a communication hole between the two upper and lower chambers. The partition wall is slidably inserted under the elastic force of a compression spring housed in the lower chamber, and a check valve is fitted to the communication hole of this partition wall to allow passage of hydraulic oil from the upper chamber to the lower chamber. Further, in the lash adjustment device in which the tappet body is provided with an introduction hole for guiding hydraulic oil into the introduction chamber, a one-way valve is provided inside the introduction hole to allow passage of the hydraulic oil toward the introduction chamber. This is a lash adjustment device for the valve train of an internal combustion engine.
