Abstract
A joined body includes: a first member having a pipe shape; and a second member including a wall portion having a plate shape, and a flange portion having a cylinder shape provided with an insertion hole through which the first member is inserted. In a state where the first member is inserted into the insertion hole of the flange portion of the second member, the first member and the second member are joined with the first member pipe-expanded. A material of the second member is larger than a material of the first member in a spring-back amount.
Claims9
A joined body comprising:
- a first member having a pipe shape;
- and
- a second member including a wall portion having a plate shape, and a flange portion having a cylinder shape and provided with an insertion hole through which the first member is inserted,
- wherein in a state where the first member is inserted into the insertion hole of the flange portion of the second member, the first member and the second member are joined with the first member pipe-expanded, and
- wherein a material of the second member is larger than a material of the first member in a spring-back amount.
A method for manufacturing a joined body, comprising:
- preparing a first member having a pipe shape, and a second member including a wall portion having a plate shape, and a flange portion having a cylinder shape and provided with an insertion hole through which the first member is inserted, the second member made of a material having a larger spring-back amount than a material of the first member;
- inserting the first member into the insertion hole of the flange portion of the second member;
- and
- pipe-expanding the first member in a radial direction toward the second member to join the first member and the second member by press-fitting.
