Abstract
An electromagnetic valve device includes a valve operating unit formed by disposing valve components in a valve housing having a guide cylinder and mounted to a base member, and a tip end of the guide cylinder and a housing body are magnetically connected to each other by a magnetic path defining frame surrounding a coil wound around a bobbin. The bobbin is buried in a mold section made of synthetic resin to form a coil unit. The coil unit is mounted to the base member. One end of the magnetic path defining frame is formed with a fitting bore through which the tip end of the guide cylinder is fitted, and the other end of the magnetic path defining frame is capable of abutting against the housing body. The magnetic path defining frame is mounted to a coil-correspondence portion of the mold section. The guide cylinder is loosely passed through a center bore of the bobbin. With this arrangement, a magnetic path can reliably be formed by the magnetic path defining frame, and the coil, bobbin and magnetic path defining frame can easily be mounted to each of the valve operating units.
