Abstract

This engine intake control device is provided with a valve guide hole (20) into which a metering hole (18c) opens a bypass valve (30) that opens and closes said metering hole (18c) a sliding piece (34) coupled to said bypass valve a threaded shaft (35) screwed into a threaded hole (42) in the sliding piece and a motor (27) that drives same. The threaded hole (42) is directly machined into the sliding piece (34). The sliding piece (34) is provided with a transverse hole (36) into which the inside end of the threaded hole (42) opens. The sliding piece (34) and a coil spring (38) that biases the sliding piece (34) in one direction are provided on the bypass valve (30). A tightly wound section (38a) of the coil spring (38) covers the transverse hole (36). A threaded hole can thus be formed in the sliding piece with high precision and foreign material that has gotten inside the bypass valve can be prevented from getting inside the threaded hole without the use of a special cover.
