PURPOSE:To make the sliding of a valve body smooth and to prevent to generate a leakage, by holding the valve body playable slightly with a valve body holder. CONSTITUTION:A valve chamber 3 is formed surrounded by a valve main body 1 and a valve seat 2, and ports A to D are arranged to the valve chamber 3. The valve body 4 can slide on the surface of the valve seat 2, and is formed to position to cover either the fluid flowing in-and-out ports A or B and the low pressure fluid port C simultaneously. A valve body holder 5 has side walls 5a at both sides, and a pawl 5b, and the valve body 4 is held playable slightly among the side walls 5a and the pawl 5b. The rear side of the valve body 4 is squeezed lightly by a retainer spring 5c. When the valve is operated by a driving lever 8, the valve body holder 5 slides on the surface of the valve seat 2 toward the valve body 4, and the flow route can be converted.
