摘要： The invention provides a compactly structured flow rate regulating valve, in which reduction of the number of parts, improvement of an assembling workability, cost reduction, downsizing, weight saving and the like can be achieved, and frictional resistance and abrasion between a valve body can be reduced and a valve main body as much as possible, so that abrasion powder can be prevented from mixing into fluid. A flow rate regulating valve is provided with a valve main body (10) having, a cylindrical valve chamber (14) with a ceiling portion (35), at least one side portion port (11, 12) which is open at the valve chamber (14), and a bottom portion port (13) which is open coaxially with the valve chamber (14), and a lower end opened cylindrical valve body (20) rotatably installed in the valve chamber (14) of the valve main body (10), and provided with an opening portion (30) having a predetermined shape in a peripheral wall portion (22) for changing an opening area of the side portion ports (11, 12) in accordance with a rotation. The valve body (20) is installed from the bottom portion port (13), a rotating shaft (25) provided in a protruding manner at a ceiling portion (23) of the valve body (20) protrudes from a bearing hole (36) of the valve main body (10) in this installed state, and a valve body locking device (40), which allows rotation of the valve body (20) but prevents the valve body from coming off downward, is installed at a protruded portion of the rotating shaft (25) from the valve main body (10).
