The lint filter device of the present invention is also constituted by the lint filter 5 which is located below the discharge port 11a of the circulation hose 11 and is disposed in the box 25 formed above the washing tub 7.

In the present invention, the lint filter 5 is composed of a case 20, a filter body 21, and rotary blades 22. The case 20 is formed in a cylindrical shape, and a step portion 20a for locking the rotary blade 22 is formed on the inner wall surface. The filter body 21 includes a mesh member 21 at the bottom of the ring-shaped frame 21a.
b is stretched, and a net made of synthetic resin is used as the net 21b. The outer diameter of the frame body 21 a is the frame 2 of the rotary blade 22.
It is formed so as to have an inner diameter of 2a. A mounting shaft 21c for the box 25 is formed in the center of the net 21b, and a locking hole 21d is provided in the mounting shaft 21c.

The rotary blade 22 has a blade main body 22b formed by ribs radially from a central mounting shaft 22c and forms a frame 22a on the outer circumference. The outer diameter of the frame 22a is a stepped portion of the inner diameter of the case 20. It is formed so as to have the same diameter as the portion enlarged by 20a. Then, a shaft hole 22d into which the mounting shaft 21c of the filter body 21 is inserted is bored in the mounting shaft 22c, and a support projection 22e for supporting the filter body 21 is formed inside the frame 22a.
