Patent number: 11955785Abstract: A resin structure includes first and second resin bodies including first and second wall portions and first and second engagement portions, respectively. One of the first engagement portions engages with one of the second engagement portions and form a first engaging part. Another one of the first engagement portions engages with another one of the second engagement portions and form a second engaging part. The first engaging part is positioned on a further front side than the second engaging part in an attaching direction of the second resin body to the first resin body. When the second resin body is rotated toward the first resin body with the first engaging part as a center of rotation and with the one of the first engagement portions being engaged with the one of the second engagement portions, the first wall portion is prevented from interfering with the second wall portion.Type: GrantFiled: October 6, 2021Date of Patent: April 9, 2024Assignee: YAZAKI CORPORATIONInventors: Kei Tomita, Kengo Ishida, Yukihiro Koyama
