Even if interior accessory 202, at length say it is that the 1st accessory 202-1 is for example the wall thickness dimension of about 2mm, by carry out the cutting of outer circumferential face for upper end portion, can cause for example one-sided narrower width for 0.7mm left and right of width that can guarantee as above-mentioned supporting surface 224.
In the narrower supporting surface 224 of this width, in the time that setting resilience is only rushed accessory 208, sometimes cannot be stably by its supporting.
In addition, in the upper bracket shown in Figure 16, be difficult to enough guarantee doughtily to utilize the retention force of riveting, sometimes because vibration input produces loosening at caulking part.
And, if produce this looseningly, can cause resilience only to rush accessory 208 and produce rotation relatively with respect to interior accessory 202, or looseningly cause that resilience only rushes accessory 208 and rock by this, now there will be the uncomfortable such problem of different sound that produces.
Therefore, in patent documentation 2, the disclosed content of patent documentation 3, such scheme is proposed,, the upper surface only rushing in resilience around side face or the center hole 210 of center hole 210 of accessory 208 arranges slot part, make man-hour a part for interior accessory 202 nip wherein riveting to add, interior accessory 202 and resilience are only rushed to accessory 208 fixing in sense of rotation.
But in this case, there is limit in the retention force of sense of rotation, confining force naturally, be difficult to by interior accessory 202 and resilience only rush accessory 208 sense of rotation strong enough fix.
