Patent number: 11926216Abstract: A vibration damping device including a vibration-damping device main unit inserted into a mounting space of a bracket from a lateral side and securely supported by the bracket. The bracket includes engaging pieces on respective opposed inside faces of the mounting space, and engaging action of the engaging pieces with respect to respective detent engaging faces formed on a fixture member of the vibration-damping device main unit prevents the vibration-damping device main unit from becoming dislodged from the mounting space of the bracket. Opposed walls of the mounting space are each penetrated by an aperture window, and inspection flat surfaces are separately provided to an outside surface of each engaging piece visible from an outside through the aperture window and a corresponding external side surface of the bracket that is off the aperture window. The inspection flat surfaces are parallel to each other.Type: GrantFiled: December 23, 2021Date of Patent: March 12, 2024Assignees: SUMITOMO RIKO COMPANY LIMITED, HONDA MOTOR CO., LTD.Inventors: Kenji Oki, Shingo Tanaka, Hiroki Kondo, Yusuke Arai, Kozo Kubota
