And can be assembled by appropriately combining them.
Regardless of the presence or absence of the hook 11, the screen plate 1 is assumed to have substantially the same height and length except for the hook 11 portion.

  Both end portions 1A and 1B of the screen plate 1 are formed so as to be hooked by being inserted into the respective slits 21 of the plate support frame 2 disposed opposite to each other. In this case, the screen plates 1 are mutually attached. A plurality of screen plates 1 are maintained at a predetermined interval between the plate support frames 2, 2 arranged so as to face each other. Try to be united.

  Further, when both end portions 1A and 1B of the screen plate 1 are inserted and latched in the respective slits 21 of the plate support frame 2, even if flowing water pressure acts on the screen, the pressure, pulsation, and driving force of the screen are applied. Each screen plate 1 is formed so as not to cause vibration and movement in the front-rear direction and the vertical direction of the screen due to vibration. This is not particularly limited. For example, as shown in FIG. 2 (B), the back-and-forth displacement of the screen plate 1 on the back side of the screen (right side in FIG. 2) is restricted. When the tongue piece 1c is projected and the end 1A of the screen plate 1 is inserted into the outer frame 31 having a U-shaped cross section through the plate support frame 2, the tongue piece 1c is formed on the inner surface of the side piece of the outer frame 31. A step 1d is formed on the side surface of the tongue piece 1c to restrict the vertical displacement, and an end 1B opposite to the end 1A is formed on the side surface of the tongue 1c. A position stop step 1a for regulating a displacement in the front-rear direction by cutting out a part thereof and a step 1b for restricting the displacement in the up-down direction are formed in series with the position stop step 1a.

As a result, when the end portions 1A and 1B are inserted into the outer frame 31, the leading ends of the positioning step 1a and the tongue piece 1c come into contact with the inner surfaces of the side pieces to restrict the displacement in the front-rear direction. In step 1d, the vertical displacement is regulated, and both end portions 1A and 1B of each screen plate 1 are inserted into the respective slits 21 of the plate support frame 2 and then inserted into the outer frame 31.
