Patent number: 10960819Abstract: A mount is slid with respect to a base to build an assembly, the base including an upper surface fixed to a vehicle, a lower surface facing a direction opposite to that of the upper surface, a first lateral surface located between the lower surface and the upper surface, and a second lateral surface located between the lower surface and the upper surface and located opposite to the first lateral surface. The mount includes a bottom surface facing the lower surface, a first lateral wall joined to the bottom surface and facing the first lateral surface, and a second lateral wall joined to the bottom surface and facing the second lateral surface. A thickness of the first lateral wall in a direction from the first lateral wall to the second lateral wall is smaller in a first lower portion than in a first upper portion.Type: GrantFiled: December 12, 2019Date of Patent: March 30, 2021Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Norihito Kitajima, Takefumi Ishida, Tomoaki Yamamoto, Yuji Matsumoto

Patent number: 10913394Abstract: A vehicular rearview mirror device includes a housing, a mirror, a camshaft, a fixed part, and a drive part. As the camshaft is rotated by a driving force transmitted from the drive part, and moves toward the fixed part by the action of a cam, a movable part including the housing, the mirror, and the drive part as a whole tilts. The drive part includes a drive source, and a gear train transmitting the driving force of the drive source to the camshaft. The gear train includes a first gear disposed to the camshaft, and a second gear that elastically meshes with the first gear.Type: GrantFiled: September 21, 2017Date of Patent: February 9, 2021Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Tsukasa Nakayama, Norihito Kitajima, Tomoaki Yamamoto, Yuji Matsumoto
