いう問題点があつた。<Means for solving the problem> However, in the conventional mounting structure of the oil level gauge guide for internal combustion engines,
When press-fitting the guide, there is no positioning around the shaft, and the structure allows it to be driven in any position around the shaft, and the guide inside the cylinder block is curved to avoid interfering with rotating parts such as the crankshaft. Depending on the position around the shaft where the guide is driven in, it may interfere with rotating parts within the cylinder block, or the oil level gauge may be driven in a direction different from the specified position relative to the oil level in the oil pan, causing oil damage. There was a problem that the amount could not be measured accurately.

湾曲した形状を有している。 The guide pipe 13 as a main body has an insertion portion 13A whose substantially lower half is formed to have a smaller diameter than a guide mounting hole 14a opened in the cylinder block 14 of the engine, and which is inserted into the internal space of the oil pan below the guide mounting hole 14a. , and a press-fitting part 13B that is formed above the guide mounting hole 14a and is press-fitted into the guide mounting hole 14a . Part 1

いる（第２図でL1＜L2）。 A positioning member 15 is fixed to the outer peripheral wall of the press-fit portion of the guide pipe 13 by welding, brazing, or the like. This positioning member 15 has the function of positioning the press-fit depth by having its bottom surface engage with the top outer circumferential edge of the guide attachment hole 14a as in the conventional case, and also has the function of positioning the press-fitting depth by bending downward from the circumferential edge as a structure according to the present invention. An axially positioning portion 15a that extends along the axis is provided. The lower end of the axial positioning portion 15a is formed below the lower end of the press-fitting portion 13B (L 1 <L 2 in FIG. 2).

となるため、製品毎のバラツキなく油量を正確に
計量することができる。 As the oil level gauge guide 12 is inserted into the guide mounting hole 14a, as shown in FIG.
Since the insertion portion 13A has a smaller diameter than the guide attachment hole 14a, it can be easily inserted with a margin. Since the lower end of the axial positioning part 15a of the positioning member 15 is located below the upper end of the protrusion 14b before the lower end of the press-fitting part 13B comes into contact with the guide attachment hole 14a, the side surface of the axial positioning part 15a is attached to the protrusion 14.
By contacting and locking the side surface of b, positioning around the axis can be performed. Then, while maintaining this state, the lower end of the press-fitting part 13B is brought into contact with the open end of the guide mounting hole 14a, and in this state, the upper end of the guide pipe 13 is driven in, so that the bottom surface of the positioning member 15 is brought into contact with the top outer peripheral edge of the guide mounting hole 14a. Press-fit the press-fitting part 13B to the locking position (see FIG. 3). As a result, the press-fit depth is also positioned, and the guide pipe 13 can be reliably attached to the set position because the position around the axis and the press-fit depth are determined. Therefore, the lower end of the curved guide pipe 13 can be prevented from interfering with rotating parts such as the crankshaft. Furthermore, since the insertion direction of the oil level gauge 11 guided by the guide pipe 13 is also constant, the amount of oil can be accurately measured without variation from product to product.
また、圧入前から軸回りの位置決めが簡単に行
えるため、位置決めに気づか煩わしさも解消さ
れ、作業能率が大幅に向上する。 In addition, since positioning around the axis can be easily performed before press-fitting, the trouble of noticing the positioning is eliminated, and work efficiency is greatly improved.

It is also possible to position the cylinder block 14 by locking it to a flat side wall of the cylinder block 14.

This makes it possible to prevent the lower end of the guide from interfering with rotating parts such as the crankshaft, and to accurately measure the amount of oil using an oil level gauge regardless of product variations.
