Embodiment Construction

[0031] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0032] figure 1 It is a cutaway front view of main parts of an internal combustion engine 1 , for example, an in-line multi-cylinder engine, to which the present invention is applied, viewed from the direction of cylinder banks. The illustrated internal combustion engine 1 has a cylinder block 2, a base 3 fixedly installed on the lower surface of the cylinder block 2, a cylinder head 4 fixedly installed on the upper surface of the cylinder block 2, and a cylinder head 4 fixedly installed on the lower surface of the base 3. Oil pan5. A head cover 6 constituting the upper portion of the internal combustion engine 1 is provided on the upper surface of the cylinder head 4 .

[0033] together according to figure 2 As shown, the head cover 6 of this embodiment is composed of a first head cover body 6a and a second head cover body 6b, the first head cover body 6a covers subs...

Abstract

The present invention provides an oil level gauge assembly structure capable of preventing misassembly of the oil level gauge whose assembly direction is specified, and suppressing a decrease in efficiency of assembly work. An insertion recess (12) provided on an upper portion of an internal combustion engine (1) is formed by an insertion hole (34a) and a peripheral wall (12b) surrounding the insertion hole and having an opening (12c) at one location. On the grip part (22) of the oil level gauge (11), form a base part (26) that is accommodated in the insertion recess and whose shape corresponds to the opening, so that the direction of the finger insertion hole (29) of the grip part becomes the direction of the finger (41). The insertion direction is aligned with the direction of the opening. By accommodating the base in the insertion recess, the direction of the oil level gauge is oriented in a predetermined direction, thereby preventing erroneous assembly. Align the insertion direction of the finger insertion hole of the grip part with the opening to perform the insertion operation, so that the finger inserted into the finger insertion hole can go in and out of the opening during operation, so that it will not interfere with other parts. Assembly of the oil level gauge Workability is good.

Description

technical field [0001] The present invention relates to an assembly structure of an oil level gauge, and more particularly relates to an assembly structure of an oil level gauge which improves the assembly workability of an oil level gauge whose assembly direction is prescribed. Background technique [0002] Conventionally, in order to check the amount of oil stored in the oil pan of the internal combustion engine of an automobile, a rod-shaped or strip-shaped oil level gauge is provided. In addition, for example, in order to downsize an engine, an oil return passage is sometimes used as a passage for an oil level gauge (for example, refer to Patent Document 1). The oil return passage is not provided as a passage for the oil level gauge, so a protective wall is provided to prevent the surface of the oil level gauge installed at the front end of the oil level gauge from touching the oil return passage when the oil level gauge is removed. In the form of the wall surface, it p...
