る。 Next, a procedure for attaching the fan 4 having the above configuration to the rotating shaft 1 will be explained. First, the boss portion 5 of the fan 4 is grasped and the shaft insertion hole 17 of the holding member 16 attached to the fitting cylinder portion 8 of the fan 4 is inserted into the rotating shaft 1 relatively. When the fan 4 is pressed in the axial direction of the rotating shaft 1 in this state, the rotating shaft 1 is relatively inserted into the fitting cylinder part 8 while expanding and deforming the spring member 13 slightly elastically. Upon completion, the spring member 13 elastically returns to its engagement protrusion 15.
is engaged with the engagement groove 3 of the rotating shaft 1. When the fan 4 is fixedly attached to the rotating shaft 1 through such engagement, the pin 2 is attached when the rotating shaft 1 rotates.
is engaged with the engagement protrusion 19 of the presser member 16, and the rotational force of the rotating shaft 1 is applied to the pin 2, the engagement protrusion 19, and the presser member 1.
6 and the mounting protrusions 12, 12 to the boss portion 5, and thus the fan 4 rotates.

なし得る。 According to the first embodiment described above, the following effects can be obtained. That is, attachment and detachment of the fan 4 can be accomplished by a simple one-touch operation of simply pressing or pulling the boss portion 5, so that the operability of attachment and detachment can be improved. Furthermore, since the engagement protrusion 15 of the spring member 13 is simply engaged with the annular engagement groove 3 on the rotating shaft 1, it is possible to attach the fan 4 to the rotating shaft 1 at any rotation angle position. Therefore, since there is no directionality when installing, it is possible to further improve operability. Furthermore, since the spring member 13 is elastically attached to the outer periphery of the fitting cylinder part 8 which is elastically deformed by the slit-like slotted groove 9, the fitting cylinder part 8 is brought into a reduced diameter state by the spring force of the spring member 13. Rotating axis 1
Therefore, the wobbling between the fitting cylinder part 8 and the rotating shaft 1 can be minimized.

きる。 Next, a second embodiment of the present invention shown in FIGS. 3 and 4 will be described. Hereinafter, only the parts different from the first embodiment will be explained. That is, 20 is a spring member in place of the spring member 13, and this is constituted by a coil spring, and an engaging protrusion 21 is formed by bending one end of the coil spring into a straight line. The inner diameter of the spring member 20 is set to be slightly smaller than the outer diameter of the fitting cylinder 8. Therefore, this spring member 20 is similar to the spring member 1.
3, it is elastically attached to the outer periphery of the distal end of the fitting cylinder part 8 and is attached in a compressed state in the axial direction. It goes without saying that substantially the same effects as in the first embodiment can be obtained, and since the spring member 20 is installed in a compressed state in the axial direction, the fitting cylinder part 8 and the rotating shaft are connected by the spring force. Since a force is applied in the direction in which the fan 4 and the rotary shaft 1 are fitted together, it is possible to prevent the fan 4 from shaking in the axial direction with respect to the rotating shaft 1.

も挿入が行ない易くなる利点がある。 5 and 6 show a third embodiment of the present invention, and only the parts different from the first embodiment will be described below. That is, a small-diameter portion 1a smaller in diameter than other parts is formed at the tip of the rotating shaft 1, and a small-diameter portion 1a of the rotating shaft 1 is formed in the inner cavity of the fitting cylinder 8. A small-diameter portion 8a having a smaller diameter than other portions is formed to fit with the portion 1a. Therefore, it goes without saying that this third embodiment can provide substantially the same effects as the first embodiment described above, and when the fan 4 is attached to the rotating shaft 1, it is possible to Since the small diameter portion 1a is formed, there is an advantage that insertion can be easily performed even when the distal end portion of the fitting cylinder portion 8 is in a reduced diameter state due to the spring force of the spring member 13.

As in the fifth embodiment of the present invention shown in FIG.
A configuration may also be adopted in which the engagement protrusion 23 is provided so as to protrude rearward from the peripheral edge of the fitting cylindrical portion 8 so as to be engaged through the cylindrical portion 8b.
