Abstract
A spoiler where when a weld face is inclined with respect to a pressurization direction, a weld rib is uniformly welded, and an outer member and an inner member are welded and fixed to each other at a stable strength. An inner member is welded and fixed to on an interior face side of an outer member by a vibration welding method. The outer member and/or the inner member before being welded has a weld rib formed on a face inclined with respect to a pressurization direction at the time of welding; a cross section of the rib is formed in a triangular or quadrangular shape; and in the cross section, two corners at both ends of a bottom edge each form an angle of 90 degrees or less.
Claims6
A spoiler structure comprising an inner member and an outer member, the inner member being welded and fixed to on an interior face side of the outer member by means of a vibration welding method,
- wherein the outer member and/or the inner member before being welded and fixed has a weld rib formed on a face that is inclined with respect to a pressurization direction at a time of vibration welding,
- a cross section of the weld rib is formed in a triangular shape,
- a bottom edge of the triangle weld rib is defined by two corners opposed to an apex as a part that comes into contact with a counterpart member, in a cross section of the weld rib, and
- in the weld rib, the two corners at both ends of the bottom edge each form an angle of 90 degrees or less.
A spoiler structure comprising an inner member and an outer member, the inner member being welded and fixed to on an interior face side of the outer member by means of a vibration welding method,
- wherein the outer member and/or the inner member before being welded and fixed has a weld rib formed on a face that is inclined with respect to a pressurization direction at a time of vibration welding,
- the weld rib includes:
- a tip end part that has a first contract area that contacts with a counterpart member at the initial time of welding;
- and
- a portion of the weld rib has a second contract area greater than the first contract area, so as to gradually increases a contact area between the weld rib and the counterpart member.
