式のシール装置に関する。[Detailed Description of the Invention] The present invention provides a sealing device for an internal combustion engine, in particular, a liquid sealant is interposed between both sealing surfaces of first and second members constituting a part of the engine body that abut against each other. The present invention relates to a sealing device in which both sealing surfaces are brought into close contact with each other by a sealant to form a sealed chamber inside the first and second members in which lubricating oil is sealed.

する等の不具合を惹起するおそれがある。 The above-mentioned liquid sealant is attracting attention because of its low cost and ease of use, but when the two sealing surfaces are abutted against each other and both members are tightened, excess sealant is released from between the sealing surfaces and the inside of the sealing surface. If the sealant that has protruded to the outside, especially the inside of the sealed chamber, falls into the sealed chamber, it may mix into the lubricating oil in the sealed chamber and cause the oil to deteriorate.
Alternatively, there is a risk of causing problems such as getting caught in a mechanical part or blocking a lubricating oil path.

性が悪い。 Therefore, it is possible to measure the required amount and apply it to the sealing surface to prevent excessive sealant from seeping out from between the two sealing surfaces, but measuring the amount of sealant each time it is applied would be very time-consuming. However, the workability is poor.

A liquid sealant is interposed between the sealing surfaces of the first and second members constituting a part of the engine body, which abut each other, and the sealant brings the sealing surfaces into close contact with each other. In a sealing device for an internal combustion engine, the sealing device for an internal combustion engine is configured to form a sealed chamber in which lubricating oil is sealed. Excess sealant that forms a groove-shaped cavity that is open and whose groove width increases approximately linearly from the bottom toward the opening, and that protrudes into the cavity from between the two sealing surfaces toward the sealed chamber side. The depth of the groove-like cavity is 5 to 30% of the width of the sealing surface.
It is characterized by being set within the range of .

し得る。 As described above, according to the present invention, the liquid sealant S is interposed between the seal surfaces 2 1 and 2 2 of the first and second members 1 1 and 1 2 that abut against each other, which constitute a part of the engine body. Then, the sealant S brings the sealing surfaces 2 1 and 2 2 into close contact with each other to form a sealed chamber 3 inside the first and second members 1 1 and 1 2 in which the lubricating oil is sealed. In the sealing device for an internal combustion engine, the both sealing surfaces 2 1 , 2 2
between the ends of the sealed chamber 3 side, the sealed chamber 3
Groove-shaped voids 5, 51 are formed which directly open into the space, and both seal surfaces 2 are formed in the voids 5, 51 .
Since the excess sealant S that protruded from between 1 and 2 2 toward the sealed chamber 3 side was accommodated and held, both sealing surfaces 2 1 ,
The excess sealant S that has protruded from the space between 2 and 2 toward the sealed chamber 3 side is placed into the groove-shaped void portions 5 and 51 located at the ends of the sealing surfaces 2 1 and 2 2 on the sealed chamber 3 side. It can be accommodated and held, and the void portions 5, 5 1
Even if a part of the excess sealant S were to bulge outside of the sealed chamber 3, the bulged portion would be integrated into the lumpy portion accommodated and held within the voids 5, 51 .
As a result, it is possible to extremely effectively prevent excess sealant S from getting mixed into the lubricating oil inside the sealed chamber 3, and the contamination can cause deterioration of the lubricating oil and damage the mechanical parts of the excess sealant S. It is possible to prevent problems such as jamming in the lubricating oil passage and blockage of the lubricating oil passage.

る。 In particular, since the groove-shaped voids 5, 51 are formed so that the groove width increases approximately linearly from the bottom toward the opening, the groove-shaped gaps 5 , 51 are The excess sealant S that has protruded into the voids 5 , 51 can fill the voids 5, 51 sequentially from the narrowest bottom to the widest opening. The sealant S can be brought into close contact with each of the opposing inner surfaces of the groove-shaped voids 5, 51 , and the excess sealant S can also effectively seal between the inner surfaces. This can contribute to improved sealing performance. Moreover, the voids 5 , 51 can be easily formed by simply chamfering the inner peripheral edge of the abutting portion of at least one of the first member 11 or the second member 12 . , can contribute to cost reduction.
