摘要： Provided is a combination structure of an electronic water valve including an electromagnetic unit including a coil body and a yoke having an upper support plate and a lower support plate and which includes a valve body including an upper member and a lower member. The combination structure includes a locking long hole formed in each of opposite sides of the lower support plate, an elastic pressing rod that protrudes, a protrusion locking rod formed on each of opposite sides of an upper portion of the upper member, and a burr blocking member which is formed on an outer circumference of the upper member and which prevents a welding burr from being exposed to an outside of an outer circumference of the valve body through a gap of a friction welding portion, the welding burr being generated when friction welding of the upper member and the lower member is performed.
