Furthermore, since the wearer's neck is covered from the rear side by the neck cover 65, it is possible to prevent air from being drawn into the cap body 1 through the gap between the neck and the cap body 1. The air flowing past the ears can prevent the generation of harsh wind noise.

Incidentally, the air introduced into the cap body 1 through the intake hole 40 and the air intake port 51 flows as shown by the arrows in FIG. The exit 60 is the cap body 1
Since the outlet passage 63 connected to the air outlet 60 extends to the rear side, the air suction effect due to the airflow flowing through the side of the cap body 1 when driving is improved. This allows air to be exhausted more efficiently. Moreover, air outlet 60
Since the opening end of the cap body 1 is covered with the air guiding member 63, rain or the like will not enter the cap body 1 through the air outlet 60.

Furthermore, the minimum opening degree of the shield plate 9 is determined by the rotation of the operating lever 27, so by once determining the position of the operating lever 27, the minimum opening degree of the shield plate 9 can be kept constant. It's convenient. Moreover, when assembling the shield plate 9 to the cap body 1, one protrusion 20 of the shield cover 13 is inserted into the insertion hole 18 of the support plate 11, and the other protrusion 21 is inserted into the ring part of the operating lever 27. 27a, both protrusions 20, 21
The tips of the screw members 10 and 24 are fitted into the recesses 12a and 12b of the engaging member 12.
It is only necessary to perform the screwing operation, and since the assembly operation can be performed with the meshing member 12, the shield plate 9, the operation lever 27, and the shield cover 13 temporarily assembled, the assembly becomes easy.

Furthermore, the opening/closing plate 57 for opening and closing the air intake port 51 is not only sandwiched between the passage member 54 and the cover 55 at its upper and lower edges, but also has a single strip extending between both side edges of the window 56. Since it is also supported by the support portion 59, it is possible not only to reliably prevent the opening/closing plate 57 from falling off the window 56, but also to have an excellent appearance.

C. Effect of the invention As described above, according to the invention, the cap body slides into contact with the lower edge of at least one end of the shield plate at a predetermined opening angle or less, and the minimum opening position of the shield plate is adjusted. An operation lever consisting of a lever part connected to a defined cam part is supported so that its rotational axis is parallel to the rotational axis of the mold plate and can be rotated in fixed angle increments, and the cam part is Since it is formed to change the sliding contact position with the lower edge of the end of the shield plate according to the rotational position, it is possible to adjust the minimum opening position of the shield plate to multiple positions by rotating the operating lever.
