Next, the function and effect of the cooling structure 62 of this embodiment will be described. In addition, the description about the effect similar to the effect obtained in 1st Embodiment is abbreviate | omitted suitably.

A fitting portion 78 to be fitted is formed. For this reason, the inlet side piping part 66 and the inlet side insertion port 74 are reliably connected by inserting the inlet side piping part 66 into the inlet side insertion port 74 until the protrusion 67 is fitted to the fitting part 78. Can do. Thereby, in the cooling structure 62, for example, compared to a configuration in which the protrusion 67 is not provided on the outer periphery of the inlet-side piping portion 66 and the fitting portion 78 is not provided on the inner peripheral surface of the inlet-side insertion port 74. The sealing performance between the portion 66 and the entry side insertion port 74 is improved. In addition, in a state where the inlet side piping portion 66 is inserted into the inlet side insertion port 74, the projection 67 is fitted into the fitting portion 78, so that it is effective for the inlet side piping portion 66 to come out of the inlet side insertion port 74. Can be suppressed. In particular, in this embodiment, since the protrusion 67 provided on the distal end side of the inlet side piping part 66 is located in the inlet side flow path 44, the protrusion 67 is an inlet side flow of the inlet side insertion port 74. It is possible to more effectively suppress the entrance side piping portion 66 from being caught by the opening edge on the side of the passage 44 and coming out of the entrance side insertion port 74. Moreover, since the recessed part 76 is formed around the entrance side insertion port 74 of the entrance side connection part 72, compared with the structure which does not form the recessed part 76 around the entrance side insertion port 74, for example, the entrance side piping part 66 The recess 76 can absorb the elastic deformation of the entry-side insertion port 74 due to the insertion of. For this reason, the sealing performance between the inlet side piping part 66 and the inlet side insertion port 74 further improves.

A fitting portion 88 to be fitted is formed. For this reason, the outlet side pipe part 68 and the outlet side insertion port 84 are securely connected by inserting the outlet side pipe part 68 into the outlet side insertion port 84 until the protrusion 69 is fitted to the fitting part 88. Can do. Thereby, in the cooling structure 62, compared with the structure which does not provide the protrusion 69 in the outer periphery of the exit side piping part 68, and does not provide the fitting part 88 in the internal peripheral surface of the exit side insertion port 84, for example. The sealing performance between the portion 68 and the outlet insertion port 84 is improved. In addition, in a state where the outlet side pipe portion 68 is inserted into the outlet side insertion port 84, the projection 69 fits into the fitting portion 88, so that it is effective for the outlet side piping portion 68 to escape from the outlet side insertion port 84. Can be suppressed. In particular, in this embodiment, since the protrusion 69 provided on the distal end side of the outlet side pipe portion 68 is located in the outlet side flow path 54, the protrusion 69 is connected to the outlet side flow of the outlet side insertion port 84. It is possible to further effectively prevent the outlet side pipe portion 68 from being caught by the opening edge on the side of the passage 54 and coming out of the outlet side insertion port 84. Moreover, since the recessed part 86 is formed around the output side insertion port 84 of the output side connection part 82, compared with the structure which does not form the recessed part 86 around the output side insertion port 84, for example, the output side piping part 68 is provided. The recess 86 can absorb the elastic deformation of the outlet side insertion port 84 due to the insertion. For this reason, the sealing performance between the outlet side piping part 68 and the outlet side insertion port 84 is further improved.

In the inlet side manifold 70 of the second embodiment, the fitting portion 78 is provided on the distal end side of the inlet side piping portion 66 in a state where the protrusion 67 provided on the back side of the inlet side piping portion 66 is fitted. The protruding portion 67 is formed on the inner peripheral surface of the inlet-side insertion port 74 so that the protrusion 67 is positioned in the inlet-side channel 44, but the present disclosure is not limited to this configuration. For example, like the inlet side manifold 92 of the modification shown in FIGS. 9 and 10, the fitting portion 93 into which a plurality of (two) protrusions 67 provided in the inlet side piping portion 66 are fitted is inserted into the inlet side. A plurality (two) of the inner peripheral surface of the mouth 74 may be formed. With this configuration, in the state where the inlet side piping part 66 is inserted into the inlet side insertion port 74, movement of the inlet side piping part 66 in the tube axis direction can be suppressed. Thereby, the sealing performance between the inlet side piping part 66 and the inlet side insertion port 74 is securable. Further, in the inlet side manifold 92 of the modified example, an annular recess portion 94 is formed between the fitting portions 93 on the inner peripheral surface of the inlet side insertion port 74.
