In the above means, the guide ribs 21, 21A, 2
2 and 22A serve as guides for the vertical movement of the spring receivers 13, thereby reinforcing the base portion 10, and the annular auxiliary ribs 23 further serve to improve the strength of the guide ribs. This helps improve the strength of the fan base as a whole, including the 9 parts and the base part 10. Furthermore, the polygonal corner portions prevent the base portion from expanding, and the strength is improved at the corner portions, and the strength is further improved by connecting the guide ribs to the corner portions. It works so that it can be measured. Further, by extending the guide ribs to the outer periphery of the base portion, an increase in the number of ribs can be suppressed as much as possible.

５と突当てても良い。 In the above configuration, since the base portion 10 is formed in a downward truss shape, the guide ribs 21, 21A, 22, and 22A protruding from the support column 9 have a higher rib height on the inner peripheral side and have increased strength. However, since these ribs are reinforced on the inside by the auxiliary ribs 23, the strength of the support column 9 is improved. Therefore, even if a rotational force is applied to the movable strut 6, the spring receiver 13 will not twist, the movable strut 6 will move up and down easily, and the guide ribs 21, 21A, 22, 2
Since the wall thickness of 2A can be made thinner, the occurrence of sink marks can be suppressed as much as possible. In addition, the outer ends of the guide ribs 21 etc. are connected to the corner parts 24A and 25 of the base part 10.
Since it extends to the direction A, that is, to the vicinity of the outer diameter portion of the base portion 10, the integral strength of the base portion 10 and the support column 9 is increased. Further, since the auxiliary ribs 23 are arranged in an annular shape, it is easy to provide, for example, supporting ribs 26 or 27 on the outer periphery of the auxiliary ribs 23, and the strength can be further improved. In some cases, the auxiliary rib 23 may be longer and protrude from the bottom plate 1.
