［産業上の利用分野］
本考案は自動車エンジンの部品として使用する
合成樹脂ダクトの補強装置に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a reinforcing device for synthetic resin ducts used as parts of automobile engines.
［従来技術］
自動車エンジンの部品、例えば吸気ダクトは、

して変形し、吸気漏れ等を生ずるおそれがあつ
た。[Prior art] Automobile engine parts, such as intake ducts,
This was proposed by the present applicant in Utility Model Application No. 129853/1985, but it is desired to replace these parts with conventional metal parts and synthetic resin parts. However, synthetic resins such as polypropylene have a lower heat deformation temperature than metals and cannot be used for parts that are exposed to engine heat. In other words, the synthetic resin intake duct receives heat at the connection portion with the engine, softens and deforms, and there is a risk of air leakage.
［考案の目的］
したがつて本考案の目的は、合成樹脂製のイン
テークダクトを好適にエンジンに接続できるイン
テークダクトの取付装置を提供するにある。[Object of the invention] Therefore, an object of the invention is to provide an intake duct mounting device that can suitably connect a synthetic resin intake duct to an engine.
［考案の構成］
本考案のインテークダクトの取付装置は、イン
テークダクトを合成樹脂で構成し、その挿入端の
内側に金属製の芯金を装着してある。[Structure of the invention] In the intake duct mounting device of the invention, the intake duct is made of synthetic resin, and a metal core is attached to the inside of its insertion end.
［考案の作用効果］

きる。[Operations and Effects of the Invention] Therefore, since the connecting portion is made of metal, even if it softens when tightened with a bundt or the like, leakage due to deformation will not occur because it is supported from the inside. Therefore, it is possible to connect with a relatively strong tightening force.
［実施例］ 以下本考案の実施例を図面により説明する。[Example] Embodiments of the present invention will be described below with reference to the drawings.

It is formed into a shape suitable for the place of use.

ダクトの変形は防止できる。 For example, in order to connect this intake duct 1 to the intake pipe 5 of a turbo 6 as shown in FIG. . Since the intake duct 1 is made of synthetic resin such as polypropylene, it tends to deform when tightened with the hose band 11, but deformation is prevented by the composition of the core metal 2, and reliable tightening can be achieved.
Even if the intake duct becomes susceptible to deformation due to the heat of the engine, the core metal can prevent the intake duct from deforming.
［まとめ］
本考案は以上のようにエンジン近傍に配置する

である。[Summary] As described above, in this invention, when converting the intake duct placed near the engine to one made of synthetic resin, a core metal is inserted into the open end of the duct to strengthen it. This allows ducts, etc., which have been prevented from being made of resin, to be made of synthetic resin, contributing to weight reduction and cost reduction of parts.
