[0062] First, refer to Figure 1 ~ Figure 13 The structure of the engine 100 of the first embodiment of the present invention will be described. It should be noted that in the following, the extending direction of the crank shaft 40 in the engine 100 is referred to as the X direction, the direction orthogonal to the crank shaft 40 in the horizontal plane is referred to as the Y direction, and the vertical direction in which the cylinder 2a extends is referred to as the Z direction. So as to explain. It should be noted that the engine 100 is an example of the “internal combustion engine” of the present invention.

[0063] Such as figure 1 As shown, the engine 100 has an engine body 10 made of aluminum alloy. The engine body 10 has a cylinder head 1, a cylinder block 2, and a crankcase 3. In addition, the automobile engine 100 composed of a gasoline engine has a timing chain cover 20 (hereinafter referred to as TCC20) and a top cover 60. The timing chain cover 20 is assembled on t...

[0134] Next, refer to Figure 15 ~ Figure 28 The second embodiment will be described. In the second embodiment, the inner diameter d1 of all the through holes 222b is set to be the same, and the TCC220 is assembled using three types of shoulder bolts 201 to 203 having different outer diameters of the rod portions 291 to 293. It should be noted that TCC220 is an example of the "cover member" of the present invention. In addition, the shoulder bolts 201 to 203 are an example of the "second fastening member" of the present invention.

[0135] In the engine using the second embodiment, such as Figure 15 As shown, TCC220 passes through the sealing member 50 (refer to Figure 16 ) Is mounted on the engine body 10 in a suspended state (refer to Figure 16 ) Of the side end. The TCC 220 has a mounting portion 222 with the inner diameter d1 of the through hole 222b all unified into the same size. Furthermore, the TCC220 is formed with shoulder bolts 201 to 203 having different outer di...

Abstract

The present invention relates to an internal combustion engine comprising: an oil seal mounted on a crankshaft of a main body of the internal combustion engine, and a cover member including an oil seal fixing portion for fixing the oil seal arranged on the crankshaft and an oil seal fixing portion disposed near the oil seal fixing portion. , and is used to attach the cover member to the first main body mounting portion of the internal combustion engine main body through the first fastening member.

Description

Technical field [0001] The invention relates to an internal combustion engine and an installation structure of a cover component of the internal combustion engine. Background technique [0002] Conventionally, there has been known a structure in which an oil seal fixing portion for fixing an oil seal mounted on a crankshaft is provided. For example, Japanese Patent Laid-Open No. 2000-46196 discloses such a structure. [0003] Japanese Patent Laid-Open No. 2000-46196 discloses an oil seal anti-dropping device, which has: an oil seal mounted on a rotating shaft (crank shaft); a housing including an opening fixed with an oil seal mounted on the crank shaft And a seal ring, which is fitted with an annular groove formed on the inner peripheral surface of the opening to prevent the oil seal from falling off. [0004] Patent literature [0005] Patent Document 1: Japanese Patent Laid-Open No. 2000-46196 Summary of the invention [0006] However, in the oil seal prevention device described ...
