の案内となるものである。 The insect screen 52 is attached by inserting tongues 53 protruding from its periphery into engagement holes formed in the base frame 4.
A water discharge part 54 is formed opposite to the engagement hole formed in the lower part of the base frame 4 to discharge rainwater that enters through the engagement hole to the outside of the base frame. The insertion groove 4
As shown in FIGS. 4 and 7, a short cylindrical portion 55 is formed at both ends of the cylindrical portion 9. On the front surface of the cylindrical portion 55, there is a screw stud for screwing a mounting frame fixing screw 56 into the cylindrical portion 55. is formed. The mounting frame 2 inserted into the upper part of the base frame 4 has a short vertical bar 47 that is integrally molded, and the vertical bar 47 is entirely connected to the cylindrical portion 55 and the insertion groove 49.
After the screw 56 is inserted into the base frame 4, the screw 56 is screwed in, and its tip presses against the vertical bar 47 to fix the mounting frame 2 to the base frame 4. At this time, the mounting frame 2 has its entire inner surface in contact with the base frame 4, so there is no wobbling. A mounting frame 3 inserted into the lower part of the base frame 4
is a structure in which a long bar-shaped vertical bar 48 is added to the vertical bar 47 of the mounting frame 2, and after pulling out the vertical bar 48 from the groove 49 as appropriate depending on the height of the window frame, the screw 56 is screwed in. The mounting frame 3 is fixed to the base frame 4 by pressing the vertical bar 48 with its tip. At this time, the vertical bar 4
The tip of 8 is located in the middle of the base frame 4. The space formed between the base frame 4 and the mounting frame 3 is closed by a panel 57 inserted into a groove formed on the inner surface of the mounting frame. Furthermore, when only the base frame 4 is attached to the window frame, if a force is applied to the base frame 4 in the longitudinal direction, the cylindrical portion 55 at the bottom of the base frame 4, or in other words, the screw 56 to the vertical bar 48, The base frame 4 and the mounting frame 3 wobble like a seesaw with the pressing point as the fulcrum. However, when the front frame 5 is attached to the base frame 4 in this state, the lower part of the reinforcing rib 45 presses the vertical bar 48, and the vertical bar 48 is pushed into the insertion groove 48.
hold within. Therefore, when the front frame 5 is attached to the base frame 4, the ventilation fan 1 is attached to the window frame without wobbling. Further, the guide oblique edge portion 46 of the reinforcing rib 45 serves as a guide when the front frame 5 is attached to the base frame 4.

An insertion groove for guiding the vertical beam of the mounting frame is formed on both sides of the base frame, and a cylindrical portion into which a mounting frame fixing screw is screwed is formed at both ends of the groove, and a cylindrical portion is formed on the inner surface of the front frame. Since reinforcing ribs for holding the vertical frame are formed in the groove, the ventilation fan can be installed with a simple structure in which the mounting frame is fixed to the base frame only at the cylindrical portion and held down by the reinforcing ribs on the front frame. It can be installed without rattling. Moreover, there is no need to make the length of the cylinder part long, and the base frame can be easily molded, which has great practical effects.
