摘要： PROBLEM TO BE SOLVED: To enhance the durability of a selector valve without making a driver feel a sense of incongruity at the occurrence of a failure.
SOLUTION: This selector valve has a spool 123 comprising a spool part a and a plunger b disposed in a freely abutting manner to the spool part a, and a spool surrounding part surrounding the spool 123 and provided with a plurality of land parts g1-g10. The spool 123 selectively takes a normal time position and a failure time position, and in the normal time position, at least angular parts Cn1, Cn2 on one side of the land b1 of the plunger b are projected from the end parts eg1, eg2 of the corresponding land part g1. Since no stepped wear part is formed on the inner peripheral surface Sr2 of the land part g1, the intrusion of foreign matters such as abrasion powder between the outer peripheral surface Sr1 of the land b1 and the inner peripheral surface Sr2 of the land part g1 is prevented at the occurrence of the failure.
