Abstract
A method for manufacturing a vehicular side door capable of suppressing occurrence of a residual deformation in a frame of a sash part and a panel member of a door body part in a manufacturing step including a heating step. The method for manufacturing a vehicular side door includes joining each of one end part of a front frame in the vehicle longitudinal direction and one end part of a rear frame to at least one door panel member, heating at least one door panel member, the front frame, and the rear frame joined in the first joining step, and joining the other end part of the front frame and the other end part of the rear frame to each other after the heating step.
Claims20
A method for manufacturing a vehicular side door, the vehicular side door comprising at least one door panel member and a sash part, the door panel member being configured of a first material having a first coefficient of linear expansion, the sash part being joined to at least one door panel member and being configured of a second material having a second coefficient of linear expansion that is different from the first coefficient of linear expansion, said method comprising:
- joining each of one end part of a front frame configuring a front portion of the sash part in the vehicle longitudinal direction and one end part of a rear frame configuring a rear portion of the sash part in the vehicle longitudinal direction to at least one door panel member;
- heating at least one door panel member, the front frame, and the rear frame;
- and
- joining the other end part of the front frame and the other end part of the rear frame to each other.
A door component, comprising:
- at least one door panel member configured of a first material having a first coefficient of linear expansion;
- and
- a sash part joined to at least one door panel member and configured of a second material having a second coefficient of linear expansion that is different from the first coefficient of linear expansion, wherein
- the sash part includes a front frame configuring a front portion in the vehicle longitudinal direction and a rear frame configuring a rear portion in the vehicle longitudinal direction,
- each of one end part of the front frame and one end part of the rear frame includes a joint part that is joined to at least one door panel member, and
- at least one of the front frame and the rear frame includes a temporarily fixing part for temporarily fixing the other end part of the front frame and the other end part of the rear frame to each other so as to allow the other end part of the front frame and the other end part of the rear frame to be relatively displaced with each other.
A side door, comprising:
- at least one door panel member configured of a first material having a first coefficient of linear expansion;
- and
- a sash part joined to at least one door panel member and configured of a second material having a second coefficient of linear expansion that is different from the first coefficient of linear expansion, wherein
- the sash part includes a front frame configuring a front portion in the vehicle longitudinal direction and a rear frame configuring a rear portion in the vehicle longitudinal direction,
- each of one end part of the front frame and one end part of the rear frame includes a first joint part that is joined to at least one door panel member, and
- at least one of the other end part of the front frame and the other end part of the rear frame includes a second joint part where a temporarily fixed state is made to be a joined state, the temporarily fixed state allowing the other end part of the front frame and the other end part of the rear frame to be relatively displaced with each other, the other end part of the front frame and the other end part of the rear frame being joined to each other in the joined state.
