保持部５１は、力布３２組付け時の折り曲げ状態において、トリムプレート３７が固定された力布３２の端部を折り曲げた状態で内部に保持する略中空直方体からなり、力布３２の端部側の幅広面が当接する固定壁５４と、組付け時固定壁５４に平行なヒンジ壁としての可動壁５５と、固定壁５４と可動壁５５とを一方の端部で連結する天壁５６と、固定壁５４，天壁５６，可動壁５５で囲まれる溝状の空間５１ｓの両端部を組付け時において閉鎖する蓋部５７，５８とを主要構成要素とする。 The attachment member 50 is integrally molded from a hard resin, is formed in an unfolded state as shown in FIGS. 5 and 6, and is bent when the side frame 10 is attached to a bent state shown in FIG. 7 .
Preparative with member 50 in the bent state in FIG. 7, a holding portion 51 made of general hollow rectangular solid, continuously from each of the two sides of one surface of the holding portion 51, a substantially plate-shaped flange portion which protrudes outward 52, 53.
The holding portion 51 is formed of a substantially hollow rectangular parallelepiped that holds the end portion of the power cloth 32 to which the trim plate 37 is fixed in the bent state when the power cloth 32 is assembled. A fixed wall 54 with which the wide side surface abuts, a movable wall 55 as a hinge wall parallel to the fixed wall 54 when assembled, and a ceiling wall 56 that connects the fixed wall 54 and the movable wall 55 at one end. The lids 57 and 58 that close both ends of the groove-shaped space 51s surrounded by the fixed wall 54, the ceiling wall 56, and the movable wall 55 when assembled are the main components.

蓋部５７，５８の固定壁５４に連続した辺に対向する辺の端部の内面には、図５に示すように、天壁５６に垂直で固定壁５４に平行な方向に延びる突起５７ｂ，５８ｂが形成されている。この突起５７ｂ，５８ｂは、折り曲げ状態において、可動壁５５に設けられた一対の凹溝５５ｇにそれぞれ係止されることにより、固定壁５４に対して可動壁５５を位置決め可能である。
また、突起５７ｂ，５８ｂは、取付部材５０が図８，図９に示すように、側板１１に組み付けられると、凹溝５５ｇ内に更に深く嵌まり込み、更に係止状態が更に強固になる。
蓋部５７，５８の天辺５７ａ，５８ａに対向する底辺５７ｃ，５８ｃは、図５〜図７に示すように、固定壁５４側及び固定壁５４逆側の端部が、矩形に切欠かれ、ヒンジ部５９で折り曲げて取付部材５０を折り曲げ状態に変形させるときの作業性を向上している。
本実施形態では、取付部材５０の組付け時に、固定壁５４及び可動壁５５は、略上下方向に延在し、蓋部は、略水平方向に延在するため、固定壁５４及び可動壁５５は、力布３２の端部側の略水平方向又は左右方向を位置規制し、蓋部５７，５８は、力布３２の端部側の上下方向を位置規制する。 As shown in FIG. 5, protrusions 57 b extending in a direction perpendicular to the top wall 56 and parallel to the fixed wall 54 are formed on the inner surfaces of the ends of the lid portions 57 and 58 facing the side continuous with the fixed wall 54. 58b is formed. The projections 57 b and 58 b can be positioned with respect to the fixed wall 54 by being locked in a pair of concave grooves 55 g provided in the movable wall 55 in the bent state.
Further, when the mounting member 50 is assembled to the side plate 11 as shown in FIGS. 8 and 9, the protrusions 57b and 58b are fitted deeper into the concave groove 55g, and the locked state is further strengthened.
As shown in FIGS. 5 to 7, the bottom sides 57 c and 58 c of the lid portions 57 and 58 that oppose the top sides 57 a and 58 a are cut out into rectangular shapes at the ends on the fixed wall 54 side and the fixed wall 54 opposite side. The workability when the attachment member 50 is bent into the bent state by being bent at the portion 59 is improved .
In the present embodiment, when the mounting member 50 is assembled, the fixed wall 54 and the movable wall 55 extend in a substantially vertical direction, and the lid portion extends in a substantially horizontal direction. The position of the end side of the webbing 32 is regulated in the substantially horizontal direction or the left-right direction, and the lid parts 57 and 58 regulate the position in the vertical direction of the side of the webbing 32.

取付部材５０のうち、フランジ部５２，固定壁５４，天壁５６，可動壁５５，フランジ部本体５３ｃは、図５，図６に示すように、同じ幅からなり、蓋部５７，５８，ガイド壁５３ａ，５３ｂが、幅方向に張り出している。
また、フランジ部５２及びフランジ部本体５３ｃは、他の部分よりも薄肉に形成されている。
取付部材５０は、フランジ部５２と固定壁５４との間、固定壁５４と天壁５６との間、可動壁５５とフランジ部との間が、それぞれ相互の角度が垂直になるように固定され、天壁５６と可動壁５５との間が、ヒンジ部５９によって略水平と略垂直の間で可動であることにより、図５，図６の展開状態と、図７の折り曲げ状態に可変になっている。 Of the mounting member 50, the flange portion 52, the fixed wall 54, the top wall 56, the movable wall 55, and the flange portion main body 53c have the same width as shown in FIGS. 5 and 6, and cover portions 5 7 and 5 8. , Guide walls 53a and 53b project in the width direction.
Further, the flange portion 52 and the flange portion main body 53c are formed thinner than other portions.
The mounting member 50 is fixed between the flange portion 52 and the fixed wall 54, between the fixed wall 54 and the top wall 56, and between the movable wall 55 and the flange portion so that the mutual angles are perpendicular to each other. Since the space between the top wall 56 and the movable wall 55 is movable between substantially horizontal and substantially vertical by the hinge portion 59, it can be changed between the unfolded state of FIGS. 5 and 6 and the folded state of FIG. ing.
