Publication number: 20240286469Abstract: A USB jack is provided below a bulging part of a door trim. Therefore, the bulging part can prevent rainwater from entering the USB jack. As a result, the USB jack can be provided on the door trim. In addition, since a connection hole is provided in the bulging part, a USB cable can be arranged to extend from an internal space of a storage part to a lower space of the bulging part through the connection hole. As a result, although the USB jack is provided below the bulging part, the USB jack and a smartphone stored in the storage part can be connected by the USB cable.Type: ApplicationFiled: June 2, 2021Publication date: August 29, 2024Applicant: KOJIMA INDUSTRIES CORPORATIONInventors: Shunpei AKAHANE, Naokatsu NOGUCHI, Haruhiko YOSHIDA, Yuusuke OGAWA, Yousuke YAMAMOTO, Tatsuhiko IKUMA, Satoshi KAWAMURA, Kimitaka KURAMOTO, Hisashi HUTATSUYA, Nobuaki TAKAHASHI
