[0005]
By the way, since the bracket is structured to be fastened to the stay via a bolt inserted through the elongated hole, there is a possibility that the mounting position is shifted with respect to the bolt. If the mounting angle of the second guide tube is shifted, the curved second guide tube may interfere with the cylinder block or the starter motor, or the guide hose may interfere with the vehicle body or the like.
[0006]
[Problems to be solved by the invention]
However, in such a conventional oil level gauge guide support structure, since the bracket is structured to be fastened to the stay via a bolt that passes through the elongated hole, the mounting position rotates around the bolt. There is a possibility of shifting in the direction. For this reason, the operation | work which attaches a 2nd guide pipe to a fixed position has become difficult.
[0007]
The present invention has been made in view of the above problems, and an object of the present invention is to make it easy to attach an oil level gauge guide in an oil level gauge guide support structure.
[0008]
[Means for Solving the Problems]
The first invention relates to an oil level gauge inserted into lubricating oil stored in an oil pan, a first guide pipe and a second guide pipe for guiding the oil level gauge to the oil pan, and a first guide pipe. And a bracket that is coupled to the proximal end of the second guide pipe on the same axis, a bracket that is coupled to the second guide pipe, and a stay that is fastened to the bracket via a bolt. Applicable to support structure of oil level gauge guide connected to.
[0009]
Then, to form a long hole for inserting the bolt into bracket, first contacting those on the left and right sides of the stay on the bracket, the second protrusion is formed, and bolts are fastened is located at one end of the elongated hole Sometimes the first protrusion abuts the left side of the stay and stops the bracket from rotating in the direction of rotation of the bolt, and when the bolt is fastened at the other end of the slot, the second protrusion The bracket is brought into contact with the right side surface of the bracket to stop the bracket from rotating in the rotation direction of the bolt .
[0011]
According to a second invention, in the first invention, a third guide pipe connected to the vehicle body side, and a guide hose for guiding the oil level gauge by connecting the third guide pipe and the second guide pipe are provided.
[0012]
Operation and effect of the invention
In the first invention, the projection does not contact the stay or the bracket, and the mounting position of the bracket is not shifted in the rotation direction around the bolt. Thereby, the operator can easily position the second guide tube, and the productivity and maintainability can be improved.
[0013]
Since the elongated hole and the first and second protrusions are formed on the bracket, even if the position of the bolt with respect to the elongated hole changes, at least one of the protrusions abuts the stay and extends the stay along the elongated hole. There is no need to reduce the size of the stay.
[0014]
In the third invention, the mounting position accuracy of the second guide tube is enhanced through the protrusion, so that the second guide tube and the guide hose are prevented from interfering with the engine body, the auxiliary machine, the vehicle body, etc. Can be prevented.
[0015]
