Abstract
A spring seat, which contacts a spool, is provided between a compression coil spring and the spool. The spring seat is shaped into a cup-shaped body, which includes a cup tubular section, a cup flange section and a cup bottom section and is fitted to a distal end shaft portion of the spool. A spring load of the spring, which is received by the cup flange section, is conducted to a distal end of the distal end shaft portion through the cup tubular section and the cup bottom section. An outer land diameter of each land of the spool is made smaller than a spring diameter of the spring.
