Abstract
A joining structure is provided which includes a first resin member and a second resin member having respective joining portions that are joined together by friction welding. The joining structure further includes a projecting wall that is opposed to the joining portions of the first and second resin members with a spacing therebetween. In the joining structure, at least one notch is formed in a surface of the projecting wall that faces the joining portions of the first and second resin members.
Claims8
A joining structure, comprising:
- a first resin member and a second resin member having respective joining portions that are joined together by friction welding;
- and
- a projecting wall that is opposed to the joining portions of the first and second resin members with a spacing therebetween,
- wherein at least one notch is formed in a surface of the projecting wall that faces the joining portions of the first and second resin members.
A joining structure comprising:
- a first resin member and a second resin member having respective joining portions that are joined together by friction welding;
- a projecting wall that is opposed to the joining portions of the first and second resin members with a spacing therebetween,
- wherein at least one notch is formed in a surface of the projecting wall that faces the joining portions of the first and second resin members;
- and
- wherein the projecting wall is formed as an integral part of one of the first and second resin members and has an end face that abuts on an opposed surface of the other of the first and second resin members at the time of completion ofjoining, so that fragments of the first and second resin members are confined in a space between the joining portions and the projecting wall.
A joining structure, comprising:
- a first resin member and a second resin member having respective joining portions that are joined together by frictional welding;
- a projecting wall that is opposed to the joining portions of the first and second resin members with a spacing therebetween;
- a liquid received in a bottom portion of a space defined between the projecting wall and the joining portions;
- and
- wherein at least one notch is formed in a surface of the projecting wall that faces the joining portions of the first and second resin members.
