Claims

[Scope of utility model registration request]

7. Electrify the fixed coil of the motor] 7) Rotate the rotor ■ integrated with the valve stem ■, and the rotation will cause the valve stem ■ and the needle formed at its tip to rotate through the external screw ■ formed on the valve stem ■. In a proportional control valve that moves a shaped valve (■) in a straight line, an expansion stopper is provided on the end face of the bearing (■) that is elastically deformable in the radial direction and has a part of its circumference divided, and a bearing holder is attached to the base of the expansion stopper. This proportional control valve uses a resin bearing (2), which has a slot (17) that fits with a hole (21) having a different diameter, such as a 0-shaped hole (21) drilled in the shaft (10), with a slight gap, as a bearing at the shaft diameter end (2) of the rotor.
