PROBLEM TO BE SOLVED: To prevent occurrence of particles due to contact of a needle valve to an inner wall of a housing and abrasion when regulating a flow rate by rotating a flow regulation knob. SOLUTION: The flow regulating valve includes a housing 11 formed with a valve hole 13, the needle valve 60 moving with respect to a valve seat 16 in the housing 11, and the flow regulation knob 40 attached to a base end of the needle valve 60 extending from the housing 11. In the flow regulating valve wherein the needle valve 60 is moved with respect to the valve seat 16 by rotating the flow regulation knob 40 and thus a flow rate of a fluid flowing through the valve hole 13 is regulated, the needle valve 60 is constituted of a first portion 64 connected to the flow regulation knob 40 and a second portion 65 engaging with the valve seat 16, and the first portion 64 and the second portion 65 are connected such that rotation of the first portion 64 based upon rotation of the flow regulation knob 40 is not transmitted to the second portion 65.
