Publication number: 20250303833Abstract: A side door structure includes an inner panel, an outer panel, a drain hole, an impact absorbing member, and a fixing member. The inner panel covers a vehicle-widthwise outer side of a side sill. The outer panel faces the inner panel and constitutes a side door together with the inner panel. The drain hole is provided in a lower end part of the inner panel and formed to drain rainwater entering the inside of the side door. The impact absorbing member is disposed inside the side door and extends in a front-rear direction of a vehicle body. The fixing member fixes the impact absorbing member to the inner panel at a position higher than a position facing the side sill. The fixing member is set to have a fixing strength at which the impact absorbing member is releasable upon input of an impact load of a predetermined load or more.Type: ApplicationFiled: March 19, 2025Publication date: October 2, 2025Applicant: SUBARU CORPORATIONInventors: Kazuhiro FUKAMACHI, Mitsuhiro IWAMOTO
