摘要：PURPOSE:To obtain a flow rate detector by which a low noise can be expected even at a high revolution of a rotor, the measuring accuracy can be improved by a stable revolution of the rotor even at a small flow speed, furthermore the installing of bearings is easily carried out, by forming the bearings of the rotor by an elastic material. CONSTITUTION:As bearings 7, 8 supporting a rotor 4 are made of an elastic material such as polyacetal resin, butadiene rubber, the vibration and noise at the revolution of the rotor 4 can be absorbed. Since the high number of revolutions of the rotor 4 per a unit flow rate can be obtained, the revolutions of the rotor 4 at the small flow speed are stabilized and an accurate measurement can be performed. Furthermore, a sufficient lubricating effect by water at the bearing parts 7, 8 can be obtd. and the durability is extended, because it can be used at the high revolutions. In particular, when the bearings 7, 8 are attached to a main body 1, the installation can be carried out easily by using elastic forces at a low cost. Thus, the prevention of noises and the improvement of measuring accuracy can be possible at a low cost.
