イルクーラの接続装置。 A heat exchange element e is arranged inside the casing 1, and has an inlet pipe on one side and an outlet pipe 3 on the other side, the outlet pipe 3 is fixed to the wall surface of the cylinder block of the engine, and the inlet pipe 2 is connected to the water pump side. In an oil cooler that is fitted to a fitting 4 with a degree of freedom in the axial direction with an O-ring 8 interposed, the tip of the fitting 4 is formed to have a slightly smaller diameter so that the inner surface of the inlet pipe 2 A connecting device for an oil cooler, in which an annular gap 9 is provided between the fitting 4 and a plurality of radial slits 10 are formed in the distal end surface of the joint fitting 4 to communicate the annular gap 9 with a cooling water flow path.
