Zusammenfassung:	PROBLEM TO BE SOLVED: To eliminate a retention part by providing a rotary valve element rotatable around the opening part of a discharge route and having a valve element flow route notched in a slide-contact part slid into contact with the opening surface thereof over the opening part of the discharge route and the opening part of one supply route. SOLUTION: A sliding type switching valve is provided with a plurality of supply routes 32 and 33 and one discharge route 31. A valve main body 2 having the opening parts 32b and 33b of the supply routes positioned on the same circumference around the opening part 31A of the discharge route and all the opening parts 31A, 32B arranged on the same plane is rotated around the opening part 31A of the discharge route. Then, a rotary valve body is provided to have a valve body flow route 41 notched in a slide-contact surface side brought into slide-contact with the opening surface thereof over the opening part 31A of the discharge route and the opening parts 32B and 33B of one supply route.
