And a part 34. The pedestal portion 32 is for attaching the receiving member 29 to the outer surface 3a of the liner 3, and since the outer surface 3a of the liner 3 is usually a curved surface, it is curved as shown in FIG. And is used for sticking to the outer surface 3a.
Therefore, after the receiving tool 29 is attached to the liner 3, the pedestal portion 32 is oriented along the outer surface 3a of the liner 3.

As is apparent from this, the neck portion 33 of the receiving member 29 is oriented along the thickness direction of the liner 3 (the direction intersecting with the inserting / removing direction of the plug-in device 28) and the head portion. 34 is oriented along the outer surface 3a of the liner 3 similarly to the pedestal portion 32. 1, 4, and 8
As shown in FIG. 5, the outer surface 3a of the liner 3 has a depth 36 capable of absorbing the thickness of the receiver 29 in the thickness direction, that is, a recess 36 having a depth capable of receiving the receiver 29 so as not to protrude from the outer surface 3a. However, it is provided such that one side thereof is opened to the end of the insertion / removal (insertion / removal) side of the insertion device 28. Therefore, the receiving tool 29 is fitted and mounted with the peripheral portion of the pedestal portion 32 partially in contact with the inner wall portion of the concave portion 36. Thus, the positioning of the receiving member 29 with respect to the outer surface 3a of the liner 3 is unique.

The pedestal portion 32 can be easily and securely fitted into the concave portion 36, and the wall surface strength of the concave portion 36 can be obtained as a detent effect (the surface pressure is kept low). Therefore, a bent rib 37 is provided. The pedestal portion 32 is provided with a rake face 38 (see FIG. 4) that is inclined in a chamfered shape at a side edge where the plug-in tool 28 is inserted and withdrawn.

It can be stapled, glued or heat welded.

As described above, the insertion tool 28 is
Needless to say, the forked protrusion 43 is made to protrude from the insertion side portion 11 and to be directed toward the receiving member 29 when being mounted on the device 1 in an overlapping manner. The bifurcated projection 43 has a crotch opening 45 having substantially the same diameter as or slightly smaller than the diameter of the neck 33 in the receiving device 29, and the entrance side (insertion / removal side) is in an upwardly expanding shape. Is formed on the inclined surface 43A and communicates with the crotch portion 45 via a narrow portion 43B.

Therefore, the bifurcated projection 4 is applied with a predetermined force or more.
When the fork 3 is pressed against the neck 33, the forked projection 43 is once opened and then returns to its original state, and the neck 33 is forcibly fitted from both sides thereof. If the bifurcated projection 43 is pulled away from the neck 33 by the force described above, the bifurcated projection 43 is once opened and comes out of the neck 33. That is, the plug 28
Is a male engaging member having a bifurcated projection 43,
Reference numeral 9 denotes a female engaging member having a neck portion 33, which is male / female engaged with resistance to disengagement, and the bifurcated projection 43 is elastically deformed at the time of insertion / removal.

The forked protrusion 43 is formed to be slightly thicker than the mounting base 42 (reference numeral 46 in each drawing).
Is the step caused by this thickening). For this reason,
When the bifurcated projection 43 is engaged with the neck 33, the bifurcated projection 43 is restrained from rattling between the pedestal part 32 and the head part 34 of the receiving tool 29, and unintentional removal Can be prevented. This thickening also leads to reinforcement of the forked protrusion 43, and furthermore,
There are various advantages, for example, it is possible to prevent unnecessary thickening of the mounting base portion 42, to suppress material cost, and to obtain easy sewing with the insertion side portion 11.

As shown in FIG. 3 to FIG.
Reference numeral 7 denotes a thin strip formed on the inner surface 2a of the shell 2.
It has a curved shape corresponding to the curve formed by the gap 12 between the liner 3 and the outer surface 3a of the liner 3. Therefore, it is easy to insert the insertion side portion 11 of the interior material 5 into the gap 12 opened in the circumferential direction. In other words, if the insertion side portion 11 remains soft in texture, it is difficult or impossible to insert into the gap 12 because the shape retention is insufficient. Is fixed to the insertion side portion 11 to secure shape retention and facilitate insertion and removal into the gap 12.

The rim 27 is also useful for fixing the mutual spacing of the plugs 28 and the mounting posture of the plugs 28 with respect to the plug side 11. As a material for forming the edging core 27, for example, a resin material such as ABS or the like, which is hardly deformed, a metal material, or the like can be used, so that the curved shape of the gap 12 may be fixed. However, it is preferable to use a flexible resin material in order to provide versatility to various mounting locations or various types of helmets. A cutout 48 is provided in the rim 27 so that the forked projection 43 can be reliably projected while avoiding interference with the forked projection 43 of the insertion tool 28 at the position where the insertion tool 28 is attached. Is provided.

Further, as shown in the figure, the edging core 27 and the insert 28 are respectively provided with a concave engaging portion 49 (a dowel hole) which is separately provided with a notch 48 as a boundary. Joint 5
It is preferable to adopt a structure in which positioning is performed by engaging and recessing with each other by a combination with 0 (dub). As a result, the effect of fixing the mutual spacing of the plugs 28 and the mounting posture with respect to the plug side 11 is further enhanced.
Further, the insertion side portion 11 is inserted into the gap 12, and the insertion tool 28
