Abstract
A leaf spring for urging a spool toward a flange part of a yoke is provided between a guide fixed to a housing and the spool. Owing to the urging force of the leaf spring, the spool is pressed against the flange part of the yoke, and the yoke can be pressed against the cover through the spool. Thus it is possible to prevent the spool and the yoke from loosening. Further because the leaf spring is provided for each magnet valve, the leaf spring can be commonly used for respective modes of a fluid control apparatus and thus the cost can be reduced.
