In this way, the shield 2 can be attached and detached only when the shield stopper 10 of the spindle fixing plate 3 and the attachment/detachment position of the shield holder 4 match, and the only thing that can make both match is the holder cover 6 is removed from the shield holder 4 only. Further, the holder cover 6 cannot be separated from the shield holder 4 and the shield holder 4 cannot be moved to the attachment/detachment position unless the lock release knob 28 is pressed.

(Effects of the Invention) As described above, the present invention provides a shield 2 that is attached to the left and right sides of the helmet 1 via the spindle fixing plate 3 and the shield holder 4 so that the front surface of the helmet can be opened and closed.
In the mounting structure, the shaft fixing plate 3 has a shaft support 8.
The shield holder 4 is provided with a shaft support 17 that is relatively rotatably fitted to the shaft support 8, and a moderation engagement piece I2.
an arc-shaped engagement groove 19 that includes a plurality of moderation engagement recesses 22 in which the gears are locked, and whose arc center is the center O of the shaft support 17; a stopper guide 120 that is concentric in front of the engagement groove 19;
A shield full opening upper limit regulating elastic piece 24 protruding into the guide groove 20 and a lock release knob 28 with a cover locking mechanism 27 are provided, and a holder cover 6 having a locking mechanism 32c is removably attached to the shield holder 4. Since the shield 2 can be attached and detached only when the holder cover 6 is removed, there is no possibility of erroneous operation and the shield 2 will not fall off even if the locking screws 13 and 14 become loose. Moreover, there is no fear that the shield 2 will fall off naturally, and the retainer etc. are not exposed, so it looks good and the design effect can be enhanced, and the holder cover 6 can be attached and detached from the shield holder 4. It is easy, and there is no need to rotate the set screws 13 and 14 when attaching and detaching the shield holder 4 to and from the spindle fixing plate 3, so there is no need for a set screw turning tool or a coin, and it is extremely easy to do. Can be attached and detached.

Also, a convex portion 23a between the moderation engagement recess 22a at the fully closed position of the shield holder 4 and the first stage open position recess 22b.
By protruding more toward the center of the shaft support 17 than the other protrusions 23b and 23c, the rotational resistance of the shield holder 4 from the fully closed position to the first stage open position increases, and wind pressure during high-speed running is increased. This prevents the shield 2 from opening naturally and allows it to be reliably maintained in the fully closed position.
