Patent number: 10968875Abstract: An intake manifold includes a passage wall portion having a first member passage wall portion provided at a first member, a second member passage wall portion provided at a second member, and an inner joint portion including a division point at which an inner joint portion is divided from an outer peripheral joint portion, the inner joint portion at which the first member passage wall portion and the second member passage wall portion are joined with each other. At least a part of the inner joint portion except for the division point is arranged at a height position closer to a middle part of a gas passage than the division point in a first direction in which the first member and the second member are opposed with each other.Type: GrantFiled: July 26, 2019Date of Patent: April 6, 2021Assignee: AISIN SEIKI KABUSHIKI KAISHAInventors: Takuma Kuriki, Tomohisa Senda, Hideaki Teramoto, Ryo Ikegami, Kyohei Ninomiya

Publication number: 20200131999Abstract: An airflow control valve structure includes a metal connecting shaft and a plastic valve body. The connection shaft includes an embedded portion. The connecting shaft is configured to rotate about a rotation axis. The embedded portion is embedded so that the valve body rotates integrally with the connecting shaft. The airflow control valve structure further includes a rotation restriction portion and a movement restriction portion. The rotation restriction portion is located on the embedded portion and restricts rotation of the embedded portion relative to the valve body. The movement restriction portion is located on the embedded portion and restricts movement of the embedded portion relative to the valve body in a direction along the rotation axis.Type: ApplicationFiled: March 28, 2017Publication date: April 30, 2020Applicant: AISIN SEIKI KABUSHIKI KAISHAInventors: Tomohiro YAMAGUCHI, Hiromitsu ISHIHARA, Kyohei NINOMIYA
