PROBLEM TO BE SOLVED: To provide a valve device that has such a configuration as to allow precise regulation of a dimension of a valve body in a moving direction with a magnet mounted thereon.;SOLUTION: A valve device 1 includes first to fourth drive coils 27 to 30, and a valve body 23 that is moved by exciting the first to fourth drive coils 27 to 30. The valve body 23 has a holder, and first to third permanent magnets 231a to 231c and an elastic member 233 that are stored in the holder. A lower-end bent portion that is bent inwardly at an angle of 90 degrees and more is formed at an open end of the holder. Thus, a dimension of the holder in an axial direction L is regulated to a predetermined dimension, and the first to third permanent magnets 231a to 231c are fixed so as not to be moved inside the holder by elastic return force of the elastic member 233 that is elastically deformed and compressed in the axial direction L.;COPYRIGHT: (C)2012,JPO&INPIT
