図４は自動車のフロアインシュレータを備えたキャブフロアを裏返した状態の斜視図であり、車体下方からの斜視図である。図４において車体を１で示し、キャブフロア４の下面に太実線の形状を有するフロアインシュレータ２が取り付けられている状態を示す。
図１は本発明の第１実施例を示す前記図４のＡ−Ａ断面図でフロアインシュレータ２の取付部の断面図である。
図１において、フロアインシュレータ２はグラスウール等の断熱材からなり、該フロアインシュレータ２の下部に配置されるエンジンからの熱を遮断する。
前記フロアインシュレータ２は、薄い板金材からなるキャブフロア４の下面を覆うもので、フロアインシュレータ２の前端部２ｂ以外の個所においては適当な接続個所５ａ（図１では車体前後方向２箇所のみ図示）においてクリップ５によってフロアインシュレータ２の下面側から、該クリップ５を挿入してキャブフロア２に固定している。 FIG. 4 is a perspective view of the cab floor provided with the floor insulator of the automobile turned upside down, and is a perspective view from below the vehicle body. In FIG. 4, the vehicle body is denoted by 1, and a state where a floor insulator 2 having a thick solid line shape is attached to the lower surface of the cab floor 4 is shown.
FIG. 1 is a cross-sectional view of the mounting portion of the floor insulator 2 in the AA cross-sectional view of FIG. 4 showing the first embodiment of the present invention.
In FIG. 1, a floor insulator 2 is made of a heat insulating material such as glass wool, and blocks heat from an engine disposed at the lower portion of the floor insulator 2.
The floor insulator 2 covers the lower surface of the cab floor 4 made of a thin sheet metal material. The floor insulator 2 is provided with appropriate connection portions 5a at locations other than the front end portion 2b of the floor insulator 2 (only two locations in the vehicle longitudinal direction are shown in FIG. 1). The clip 5 is inserted into the cab floor 2 by the clip 5 from the lower surface side of the floor insulator 2.

前記フロアインシュレータ２の前面は、下方に傾斜した傾斜面２ａとなっており、また前記キャブフロア４の前面４ａも前記フロアインシュレータ２の傾斜面２に沿って下方に傾斜している。そして前記キャブフロア４の前面４ａに続いて水平な前端部４ｂが形成されている。   The front surface of the floor insulator 2 is an inclined surface 2 a inclined downward, and the front surface 4 a of the cab floor 4 is also inclined downward along the inclined surface 2 of the floor insulator 2. A horizontal front end 4 b is formed following the front surface 4 a of the cab floor 4.

接続部７には、前記前面キャブフロア３後端部を延長させて、さらに下方に曲げて支持部３ａを形成し、該支持部３ａの曲げ部分３ｂに前記フロアインシュレータ２の前端部２ｂを当てるようして位置決めして、該前端部２ｂの部分を水平な前端部４ｂ、曲げ部分３ｂ、支持部３ａによって包み込むようにして形成している。
そして、前記キャブフロア４の前端部４ｂを前記前面キャブフロア３の前記接続部７で接続し、前記接続部７の部分に形成される前記キャブフロア４の前端部４ｂと前面キャブフロア３の後端部３ｃ（前記支持部３ａ及び曲げ部分３ｂ）との合わせ部分にフロアインシュレータ２の前端部を挿入して、これらキャブフロア４の前端部４ｂと前面キャブフロア３の支持部３ａとの隙間にフロアインシュレータ２の前端部２ｂを固定している。 The connecting portion 7 is formed by extending the rear end portion of the front cab floor 3 and bending it further downward to form a support portion 3a. The front end portion 2b of the floor insulator 2 is applied to the bent portion 3b of the support portion 3a. Thus, the front end portion 2b is formed so as to be wrapped by the horizontal front end portion 4b, the bent portion 3b, and the support portion 3a.
Then, the front end portion 4b of the cab floor 4 is connected by the connecting portion 7 of the front cab floor 3, and the front end portion 4b of the cab floor 4 formed in the connecting portion 7 portion and the rear of the front cab floor 3 are connected. The front end portion of the floor insulator 2 is inserted into a joint portion with the end portion 3c (the support portion 3a and the bent portion 3b), and the gap between the front end portion 4b of the cab floor 4 and the support portion 3a of the front cab floor 3 is inserted. The front end 2b of the floor insulator 2 is fixed.

Efficiency is improved.

従って、かかるキャブフロア当て板６の省略によって、該キャブフロアあて板ｂの取り付け精度を管理する必要が無くなると共に、部品点数の減少及び重量が減少し、これにより低コスト化できる。
また、前面キャブフロア３後端部の支持部３ａの曲げ部分３ｂに前記フロアインシュレータ２の前端部２ｂを包み込んで支持した状態で、クリップ５でクリップ止めをするので、作業が簡単にでき、作業工数が低減される。 Accordingly, the omission of the cab floor abutting plate 6 eliminates the need for managing the mounting accuracy of the cab floor facing plate b, and reduces the number of parts and the weight, thereby reducing the cost.
In addition, since the front end portion 2b of the floor insulator 2 is wrapped and supported in the bent portion 3b of the support portion 3a at the rear end portion of the front cab floor 3, the clip is fixed with the clip 5, so that the work can be easily performed. Man-hours are reduced.

この第２実施例においては、キャブフロア４の前端部４ｂを前面キャブフロア３の後端部３ｃに接続部８で接続し、該接続部８より前記前面キャブフロア４の後端部を直状に伸ばし、該直状の先端部に支持部１０を形成し、フロアインシュレータ２の前端部２ｂを支持部１０とキャブフロア４の前面４ａの傾斜前端部４ｄとで形成される隙間Ｓ内に位置させ、該隙間Ｓの先細になっている方向にフロアインシュレータ２の前端部２ｂを押当てて位置決めして、支持部１０とキャブフロア４の傾斜前端部４ｄとの間にフロアインシュレータ２の前端部２ｂを挟むようにして保持して前端部２ｂを固定する。 FIG. 2A is a cross-sectional view of the floor insulator mounting portion taken along the line AA of FIG. 4 showing the second embodiment of the present invention. FIG. 2B shows a modification thereof.
In the second embodiment, the front end portion 4b of the cab floor 4 is connected to the rear end portion 3c of the front cab floor 3 by a connecting portion 8, and the rear end portion of the front cab floor 4 is straightened from the connecting portion 8. The support portion 10 is formed at the straight tip portion, and the front end portion 2b of the floor insulator 2 is positioned in a gap S formed by the support portion 10 and the inclined front end portion 4d of the front surface 4a of the cab floor 4. The front end portion 2b of the floor insulator 2 is pressed and positioned in the direction in which the gap S is tapered, and the front end portion of the floor insulator 2 is positioned between the support portion 10 and the inclined front end portion 4d of the cab floor 4. The front end 2b is fixed by holding it so as to sandwich 2b.

従って、かかる第２実施例によれば、前面キャブフロア３の後端部３ｃを直状に伸ばし、該直状の先端部に支持部１０を形成し、フロアインシュレータ２の前端部２ｂを支持部１０とキャブフロア４の前面４ａの傾斜前端部４ｄとで形成される隙間Ｓ内に位置させて、該隙間Ｓに押当てて位置決めして、支持部１０とキャブフロア４の傾斜前端部４ｄとの間にフロアインシュレータ２の前端部２ｂを挟むようにして保持するので、作業工数が低減される。
また、従来のキャブフロア当て板６（図３参照）を省略できて、部品点数の減少及び重量が減少しこれにより低コスト化できる。 Therefore, according to the second embodiment, the rear end portion 3c of the front cab floor 3 is straightened, the support portion 10 is formed at the straight tip portion, and the front end portion 2b of the floor insulator 2 is supported by the support portion. 10 and the inclined front end portion 4d of the cab floor 4 are positioned within a gap S formed by the inclined front end portion 4d of the front surface 4a of the cab floor 4 and pressed against the gap S for positioning. Since the front end 2b of the floor insulator 2 is held between the two, the man-hours for work are reduced.
Further, the conventional cab floor backing plate 6 (see FIG. 3) can be omitted, and the number of parts and the weight can be reduced, thereby reducing the cost.
