-3728 and Japanese Utility Model Laid-Open No. 55-55719 disclose a gauge body that is inserted into oil in the crankcase through a guide pipe that opens in the crankcase, and a guide pipe that is provided at the base end of the gauge body. There is known a level gauge including a cap or a stopper that closes the open end surface of the above, and a grip portion that extends outside the guide pipe from the cap or the stopper.
この従来のレベルゲージでは、キャップ乃至はストッパ
を除く、ゲージ本体と把持部が共に金属製であって、リ
ベットで中継されていた。In this conventional level gauge, both the gauge body and the gripping portion, excluding the cap or stopper, are made of metal and relayed by rivets.
＜考案が解決しようとする問題点＞ この様に従来のレベルゲージにあっては、ゲージ本体と
把持部を金属で別加工し、リベットで相互に接合しなけ

ベットによる係止部分が露呈してしまうため、体裁が非
常に悪かった。<Problems to be solved by the invention> As described above, in the conventional level gauge, it is necessary to separately process the gauge body and the grip portion with metal and join them with rivets, which is troublesome to manufacture. Not only did it hang, but the locking part by the rivet was exposed, so the appearance was very bad.
そこで、本出願人等は、金属製のゲージ本体をインサー
ト成形して、その把柄をプラスチックで一体成形するこ
とを考えた。Therefore, the present applicants considered to insert-mold a metal gauge body and integrally mold the handle with plastic.
しかし、成形時のゲートの設定位置により成形不良が生
じた。However, defective molding occurred depending on the setting position of the gate during molding.
当初は、そのゲート位置をリング状の把持部の長さの途

本体が把柄から抜け、ゲージ本体をオイル中に落下して
取出せなくなるという問題もあった。Initially, the gate position was set in the middle of the length of the ring-shaped grip, but due to the flow of molten plastic during molding, there was a problem that the gauge body was attached diagonally to the handle. . Further, there is a problem that the joint portion between the handle and the gauge body is poorly filled with resin, and the gauge body comes out of the handle after being used for a long period of time, and the gauge body falls into oil and cannot be taken out.
＜問題点を解決するための手段＞ そこで本考案は、前記問題点を解決するものであって、
以下にその内容を図面に示した実施例に基き説明する。<Means for Solving Problems> Therefore, the present invention is to solve the above problems, and
The contents will be described below based on the embodiment shown in the drawings.
本考案は、金属製のゲージ本体２の基端部を把柄３の圧
入部10中にインサートして、この把柄３をプラスチック
で一体成形すると共に、前記圧入部の先端にテーパ面16
を形成し、把柄を成形するプラスチックのゲートＧを前
記テーパ面16に設定したことを特徴とするものである。According to the present invention, the base end portion of the metal gauge body 2 is inserted into the press-fitting portion 10 of the handle 3, the handle 3 is integrally molded with plastic, and the tapered surface 16 is provided at the tip of the press-fitting portion.
And a plastic gate G for forming a handle is set on the tapered surface 16.

An annular fitting groove 15 for fitting the O-ring 14 therein is provided at the position of the constricted portion 9, and by making the positions of the fitting groove 15 and the constricted portion 9 coincide, the thickness of the molded product is made uniform. Also, press-fitting section
The tip end of 10 is formed into a truncated cone shape, and a taper surface 16 is formed on the outer peripheral surface thereof so as to be obliquely cut off to improve the insertability into the guide pipe 5. And
By setting the plastic gate G for forming the handle 3 on the tapered surface 16, the molten resin for forming the handle 3 flows smoothly along the base end portion of the gauge body, and the gauge body is inclined with respect to the handle. Installation can be prevented.
Further, the joint between the base end of the gauge body and the press-fitting portion of the handle is sufficiently filled with resin, and the mounting strength of the gauge body is not reduced. Further, even if the mark of the gate is formed in a convex shape, it is on the tapered surface 16 that the press-fitted portion 10 is inserted into the guide pipe 5.
Does not prevent insertion into or removal from. Therefore, the press-fitting portion can be smoothly inserted into and removed from the guide pipe without the need for post-processing to scrape and remove the convex gate mark.
更に、リング状の把持部13の柄12の平坦部分を利用して

Not only can the problem that the gauge body is attached to the handle attached diagonally can be solved, but also the joint between the press-fitting part and the base end of the gauge body can be sufficiently filled with resin, and the gauge body can be attached to the handle. Prevents lack of strength and prevents the gauge body from coming off. Further, even if the gate mark is formed in a convex shape, it is generated on the tapered surface 16 at the tip of the press-fitting portion, so that there is no problem in inserting and removing the press-fitting portion into the guide pipe.
これに加え、把柄は容易に着色できるので、エンジンル
