Claims

[Claims for Utility Model Registration] (1) Pivot bases fixed on both sides of the helmet;
A shield attachment mechanism for a helmet, comprising a pivot part formed on both sides of the shield and rotatably attached to the pivot base, and a cover for covering the pivot base and the pivot part. Each of the pivot bases is formed into a plate shape, and a female fitting member having one or more fitting recesses substantially parallel to the surface is provided on the surface thereof, and the female fitting member has one or more fitting recesses substantially parallel to the surface. A male fitting member corresponding to the position of the additional fitting recess is provided on the back surface, and by fitting the male fitting member into the fitting recess of the female fitting member,
A helmet shield attachment mechanism, characterized in that the cover can be detachably fixed to the pivot base. (2) The female fitting member has a substantially U-shaped cross section with one side open, and has a slit on one side, and the male fitting member has a substantially T-shaped cross section. 2. The helmet shield attachment mechanism according to claim 1, wherein the helmet shield attachment mechanism is formed in a letter-shaped shape. (3) A soft string-like member is interposed between the pivot base and the cover and is detachably engaged with the pivot base for connecting the cover to the pivot base. The helmet shield attachment mechanism according to claim 1 or 2.
