A water jet gun includes a gun-like body which has a handle portion and a transverse tubular housing portion enclosing a hollow plug. The tubular housing is provided with a first opening communicated with the handle portion and the hollow plug has a second opening to communicate with the first opening to form a flow passage. The second opening is tapered from one end thereof to another opposite end in the circumferential direction of the hollow plug so that the dimension of the flow passage is variable upon the rotation of said hollow plug. The hollow plug is further provided with a spout which provides water jets of different patterns.
