A joining structure, comprising:
- a first member having a cylindrical hollow portion;
- and
- a second member that is cylindrical in shape, has an outer circumferential diameter equal to or larger than a diameter of the hollow portion, and is to be pressed into the hollow portion, wherein
- a concave portion, which is cut out inward from an outer circumference of the first member, is formed on part of a portion of the first member into which the second member is pressed.
A joining method for joining a first member having a cylindrical hollow portion, and a second member that is cylindrical in shape, has an outer circumferential diameter equal to or larger than a diameter of the hollow portion, and is to be pressed into the hollow portion, the method comprising:
- a concave forming step of forming a concave portion, which is cut out inward from an outer circumference of the first member, on part of a portion of the first member into which the second member is to be pressed;
- and
- a pressing step of pressing the second member into the hollow portion.
A method of manufacturing a resin member for joining structure having a hollow portion into which a cylindrical member is pressed for joining, the method comprising
- molding the resin member by pouring a liquid resin constituting the resin member into a metal mold from a portion different from a portion into which the cylindrical member is to be pressed, and then solidifying the liquid resin.
