In addition, the poppet assembly is attached in a floating state to the pressure oil flow hole 22 of the valve body 21, and a play is always formed between the poppet body 27 and the valve seat 35 to allow oil to flow out. A check valve characterized in that when hydraulic pressure increases, the poppet main body 27 is pushed inward of the cylindrical body 28 to allow pressure oil to flow out.
