A bent portion of the plate is formed to be inclined at a certain angle in the direction of insertion into the center hole, and the bent portion of the plate is elastically bent against the annular protrusion of the connector pipe by the elastic force of the plate itself. An oil cooler characterized by being pressed. (2) The annular projection of the connector pipe has a tapered shape in which the diameter gradually decreases toward the tip where it is inserted into the hole formed by the bent portion, as claimed in claim (1) of the utility model registration. Oil cooler as described. (3) The angle θ between the bent portion of the plate and the central axis of the connector pipe is θ=0.3° to 45°.
The oil cooler according to claim (1) of the utility model registration, which is: (4) The bent portion of the plate is formed into a substantially circular arc shape, and the innermost edge of the bent portion does not contact the annular projection of the connector pipe, but is slightly above the innermost edge and contacts the annular projection. An oil cooler according to claim (1) of the related utility model registration claim. (5) The oil cooler according to claim 1, wherein the outer diameter of the lower threaded portion of the connector pipe is smaller than the outer diameter of the annular projection.
