ある。 As a means to solve these problems, that is, to explain the drawings as an embodiment. Fig. 1 shows a multi-blade fan F to which this retaining plate with a boss is attached, and the retaining plate 1 is made of soft plastic. Alternatively, a rubber material is formed with a polygonal fitting hole 2 in the center, and a metal or hard plastic is formed in the fitting hole, and the outer shape is approximately the same so as to fit into the fitting hole 2 of the retaining plate 1. A polygonal fitting part 4 is provided (see Fig. 2 and Fig. 3), and this fitting part 4 is inserted into the fitting hole 2 of the holding plate.
The cylindrical boss and the cylindrical boss 3 are fitted into one body, and an annular push nut 5 is fitted from the front and back to the cylindrical boss and the holder plate to firmly hold them together. be. The retaining plate with a boss configured in this way has several mounting holes 6 provided on the circumference thereof, and screw holes provided in the side plate 7 for assembly of the fan.
Or, fix it with screws or rivets according to the hole. Note that 8 is a screw hole for connecting the motor rotating shaft.

傷を与えない効果大である。 As an effect of the present invention, as described above, the holding plate of the cylindrical fan is molded from soft plastic or a rubber material of appropriate hardness, and a polygonal fitting hole 2 is provided in the center. The fitting portion 4 of the boss 3, whose outer side is approximately the same shape, is fitted into this fitting hole 2 and integrally connected, so that the two do not slip even when the motor rotating shaft attached to the boss rotates at high speed.
Moreover, since the retaining plate and the boss are more firmly connected from both sides by the annular push nut 5, the ideal retaining plate with a boss prevents the boss from shifting back and forth with respect to the retaining plate. This is a cylindrical multi-blade fan, and the elasticity of the boss and retaining plate allows the fan to rotate smoothly and is highly effective in preventing damage to the motor.
