The full-face helmet 1 shown in FIG.
A shield 3 is provided to open and close a window hole formed on the front surface of the shell 2, and both shield ends 4 are attached to both sides of the shell 2, respectively. The surface side of this attachment part is covered with a shield cover 5, and the shield cover 5, the shield end 4, and the shell 2 are fastened together at two places, upper and lower, by a connecting member 6 having a decorative screw-shaped head. There is.

軸を兼ねている。 On the other hand, the shield cover 5 is also a plate-like member made of resin, and a recess 9 is formed at a position corresponding to the mounting hole 8 of the shield end 4 and at a position below the mounting hole 8 that does not interfere with the rotation of the shield end 4. There is. These recesses 9 are deep enough to accommodate the head of the connecting member 6, and on the opposite side are bosses 9a and 9b that protrude toward the back surface of the shield cover 5, as shown in FIG.
The upper boss portion 9a fits into the mounting hole 8 of the shield end portion 4, and also serves as a rotation support shaft for the shield 3.
これら凹部９の底部にはそれぞれ取付穴１０が
貫通形成され、各取付穴１０にはこれを横断して
半径方向へ延びる長孔１１が形成されている。 Attachment holes 10 are formed through the bottoms of these recesses 9, and elongated holes 11 are formed in each attachment hole 10 to extend in the radial direction across the attachment holes 10.

された係合突起７ａのストツパーである。 The periphery of the shield cover 5 is bordered in a rib shape by a wall portion 12 formed upright to a height equivalent to the thickness of the shield 3, and is provided with a predetermined rigidity.
However, a low rib-shaped step part 13 is formed on the front side of the upper part of the wall part 12, and consideration is given so that the shield 3 does not come into sliding contact and damage this surface when it rotates. Further, a click guide 14 is integrally formed at the inner lower part of the shield cover 5 so as to follow the rotation locus of the engaging protrusion 7a of the click arm 7.
This click guide 14 is also formed to be protruding from the general surface of the shield cover 5 and to be relatively long, thereby contributing as a reinforcing rib for the shield cover 5, and furthermore, the engaging protrusion 7a is engaged along the length direction. A plurality of click grooves 15 are formed for this purpose. Note that one end portion of the click groove 15 is continuous with the lower boss portion 9b. 9c is a stopper of the engagement protrusion 7a formed on the boss portion 9a.
連結部材６は頭部から突出し取付穴１０の内径

長孔１１に嵌合可能な係合突部１７が延出形成さ
れ、全体が略Ｔ歯状の結合部材となつている。 The connecting member 6 has a shaft portion 16 that protrudes from the head and has a diameter somewhat smaller than the inner diameter of the mounting hole 10, and has a tip formed in a rounded curved surface that can be fitted into the elongated hole 11 in the radial direction. The engaging protrusion 17 is formed to extend, and the whole is a substantially T-shaped coupling member.

性を良好にしている。 Therefore, the connecting member 6 can penetrate the shield cover 5 by aligning the mounting hole 10 with the shaft portion 16 and the elongated hole 11 with the engagement protrusion 17, and the engagement protrusion 17 on the back side.
By attaching an O-ring-shaped elastic body 18 with a diameter slightly smaller than the length between both ends around the shaft portion 16, the elastic body 18 is integrated so as not to fall off from the shield cover 5, and the connecting member 6 is prevented from dispersing when being attached or detached. It has good sex.

This part of the inside of the shell 2 is shown in FIG. 4, which is a cross section along the elongated hole 21, and FIG.
A cam surface 22 is formed on the circumferential surface of 0, gradually protruding from one elongated hole 21 side and covering approximately 1/3 of the circumference. The cam surface 22 is connected at its most raised portion to a flat engagement step 23, and further adjacent to the engagement step 23, a stopper wall 24 is formed to protrude. Engagement grooves 25 are formed radially at the boundary between the engagement step portion 23 and the stopper wall portion 24 .

As shown in the figure, attach the shield end 4 to the shell 2 side, then stack the shield cover 5 on the shield end 4 and attach the upper boss 9a to the shield end 4.
into the mounting hole 8, then each mounting hole 10, 20.
and the elongated holes 11 and 21 respectively, and the engaging protrusion 17 and the elongated hole 11 are made to coincide with each other to form the connecting member 6.
When pushed into the shell 2 side, the engagement protrusion 17 passes through the elongated holes 11 and 21 and protrudes inside the shell 2. Therefore, when the connecting member 6 is rotated approximately 1/3, the engagement protrusion 17 is guided by the cam surface 22 and rotates while compressing the elastic body 18 and engages with the engagement step 23. When it comes into contact with the stopper wall 24, the rotation stops and further engages with the engagement groove 25. The installation work is completed. Therefore, the work is much faster than the conventional screw fastening work. Moreover, since the elastic body 18 is interposed, the shield cover 5 can be attached to the shell 2 without rattling due to its elasticity, and will not easily loosen even after long-term use. Furthermore, since the tip of the shaft portion 16 is curved, fitting into the mounting hole 10 is facilitated. Furthermore, since the hole diameter of the mounting hole 10 is larger than the shaft portion 16, when installing the shield cover 5, the position can be adjusted by finely adjusting the movement in various directions such as up and down, front and back, etc.
Increased flexibility in installation adjustment.
そのうえ、係合溝２５を設けたことにより、係
合突部１７の係合時における良好な節度感が与え
られるとともに、緩み防止にもなる。 Furthermore, the provision of the engagement groove 25 provides a good sense of moderation when the engagement protrusion 17 is engaged, and also prevents loosening.

When attaching the shield cover to the shell, it can be stopped by turning the connecting member about half a turn, making the attachment work faster than conventional screw fixing work. Moreover, since the elastic member is interposed between the shield cover and the shell, looseness during installation is reduced and the shield cover is less likely to loosen even after long-term use.
