In addition, skew wall portion 38 is by the installation face 14 in sealing surface portion 30a whole region between bolt hole and side wall 26a
Bottom link form be and " whole region of sealing surface portion between bolt hole is connected by inclined wall with side wall " in the present invention
The corresponding implementation structure of form an example, the form that skew wall portion 38 is connected with a pair of bolts lug portion 34 is and this hair
One example of the corresponding implementation structure of the form of " inclined wall and the 1st hole edge department and the 2nd hole edge department are connected " in bright.Separately
Outside, skew wall portion 38 is an example of the implementation structure corresponding with " inclined wall " in the present invention, and a pair of most end row bolts are passed through
Perforation 132 is an example of the implementation structure corresponding with " the 1st bolt-through hole " and " the 2nd bolt-through hole " in the present invention
Son.
As shown in figure 1, outlet part 4 is installed on the installation face 14 to be formed in the side wall 26a of cylinder cover 1 with cantilever position.
Outlet part 4 is the parts for the part for constituting cooling water path, be configured to will to export from water jacket 36 cooling waters that flow out to
Radiator (not shown), heater etc. are distributed.
Then, the action in the action for the cylinder cover 20 of present embodiment for illustrating so to constitute, especially skew wall portion 38.When
When the internal combustion engine 1 for being equipped with the cylinder cover 20 of present embodiment is operated, the gaseous mixture of air and fuel occurs in the CC of combustion chamber
The combustion explosion caused by igniting of body.
Due to the combustion explosion, cylinder cover 20 is from stress (hereinafter referred to as blast load) on the separated direction of cylinder body 6.So
And, cylinder cover 20 is anchored on cylinder body 6 by fastening bolt, therefore, and blast load actually causes as the installation installed to cylinder body 6
The sealing surface portion 29 in face, particularly combustion chamber sealing face 29a deformation.
Here, near the combustion chamber sealing face 29a bolt-through hole 32 run through of confession fastening bolt part, fasten spiral shell
The axial force of bolt effectively works, therefore, it is possible to effectively bear to act on burning using the axial force of the fastening bolt
Room sealing surface portion 29a blast load, can suppress combustion chamber sealing face 29a deformation.
On the other hand, the part between the bolt-through hole 32 in combustion chamber sealing face 29a, the axial direction of fastening bolt
Power is difficult to effectively work, therefore, and combustion chamber sealing face 29a is easy to be deformed.In the present embodiment, skew wall is utilized
Portion 38 is by the burning around the combustion chamber CC of the one end being configured in the orientation of combustion chamber (side wall 26a sides, Fig. 4 upside)
The bottom of installation face 14 between bolt hole in the sealing surface portion 29a of room in sealing surface portion 30a whole region and side wall 26a
Link up, sealing surface portion 30a is in a side (side wall 26a sides, the Fig. 4 being configured in the orientation of combustion chamber between the bolt hole
Upside) a pair of most end row bolt-through holes 132 between extend.
Thereby, it is possible to the blast load that will act on sealing surface portion 30a between bolt hole side wall 26a is utilized via skew wall portion 38
Bear.In other words, can reduce by it is in the deformation caused by sealing surface portion 30a blast load between acting on bolt hole, make
Cylinder cover 20 is from the composition on the separated direction of cylinder body 6 (the top direction in Fig. 5).As a result, can effectively suppress bolt
Sealing surface portion 30a deformation between hole.
Moreover, skew wall portion 38 is also connected with being formed with a pair of bolts lug portion 34 in a pair of most end row bolt-through holes 132,
Therefore, it is possible to make the responsive to axial force of the fastening bolt sealing surface portion 30a between bolt hole via skew wall portion 38.Thereby, it is possible to profit
More effectively suppress the deformation of sealing surface portion 30a between bolt hole with both axial forces of side wall 26a and fastening bolt.
In addition, in the operation process of internal combustion engine 1, because piston P reciprocating motion produces vibration, the vibration is also acted on out
Water portion 4.Outlet part 4 is installed on the installation face 14 of cylinder cover 20 with cantilever position, therefore, and the bending produced by the vibration is inputted
Act on installation face 14.
In addition, except the bending input action produced by vibration is in addition to face 14 is installed, being produced by the deadweight of outlet part 4
Bending input also act on installation face 14.However, in the present embodiment, the bottom for installing face 14 utilizes skew wall portion
38 are linked to combustion chamber sealing face 29a, therefore, it is possible to make to be caused by the bending input for acting on the bottom for installing face 14
Pulling force, compression stress born via skew wall portion 38 using combustion chamber sealing face 29a.Thus, it can improve and the firm of face 14 is installed
Spend and can effectively suppress that the deformation of face 14 is installed.
In the present embodiment, it is set to the sealing surface portion 30a end edge portion 30a ' between bolt hole of skew wall portion 38 whole area
The structure that domain links combustion chamber sealing face 29a and side wall 26a, but it is not limited to this.For example, it is also possible to be that skew wall portion 38 exists
Sealing surface portion 30a end edge portion 30a ' at least a portion links combustion chamber sealing face 29a and side wall 26a between bolt hole
Structure.
In this case, as shown in Figure 4, it is desirable to be set to the sealing surface portion 30a between bolt hole of skew wall portion 38 ora terminalis
The part FP that the distance at the centers that row bolt-through hole 132 is most held away from a pair in portion 30a ' is farthest is facial by combustion chamber sealing
The structure that 29a and side wall 26a links.
, can be effectively close between suppression bolt hole while skew wall portion 38 is suppressed into Min. according to the structure
Being most difficult to work so as to being easy to the deformation of part being deformed due to the axial force of fastening bolt in front cover portion 30a.
In addition, most being held away from a pair in row bolt-through hole 132 in sealing surface portion 30a end edge portion 30a ' between bolt hole
The farthest part FP of the distance of the heart is and " center at least away from the 1st bolt-through hole and the 2nd bolt in edge in the present invention
