Patent number: 11959543Abstract: The disclosure provides a lubricating structure for a vehicle power transmission device that may effectively lubricate a transfer device and a differential device without increasing the amount of oil. The lubricating structure includes: a first guide wall positioned above a bearing; a second guide wall provided below an oil reservoir and extending toward a central axis of a final driven gear; and an oil catch member that receives oil guided by the second guide wall and supplies the oil to a differential device and the bearing. The oil catch member includes a first inclined part inclined so that a direction of the first guide wall is lowered, a notch formed at a position facing an opening formed in a differential case, and a groove for oil guiding that extends toward the bearing.Type: GrantFiled: February 6, 2023Date of Patent: April 16, 2024Assignee: Honda Motor Co., Ltd.Inventors: Takuto Kanase, Nobutaka Fukamizu, Seiji Ishii, Takeo Furuta

Publication number: 20230406083Abstract: A first inclined part (41) and a second inclined part (11) inclined inward in a vehicle width direction toward a rear of the vehicle are respectively provided on a surface (40c) facing an outer side in the vehicle width direction in a cover member (40) covering an opening (34) of a casing (30) and a surface (10d) facing an inner side in the vehicle width direction in a side frame (10). The first inclined part (41) and the second inclined part (11) are at positions at least partially facing each other. The first inclined part (41) is inclined more than the second inclined part (11). A rear end (40b) of the first inclined part (41) in the cover member (40) extends to a position behind a mating surface (35) with the cover member (40) in the casing (30).Type: ApplicationFiled: May 2, 2023Publication date: December 21, 2023Applicant: Honda Motor Co., Ltd.Inventors: Shuji KURODA, Nobutaka FUKAMIZU

Patent number: 9586349Abstract: A detecting sensor is disclosed having a magnet, a plurality of magnetic field detecting sensor elements, and a housing. The magnetic field detecting sensor elements have a plurality of adjacent, overlapped bodies and a plurality of terminals projecting from the bodies in a same direction. The housing is disposed over the magnet and plurality of sensor elements, and has first and second sensor holding members. The first sensor holding member is positioned on a first side of the housing and abutted against a surface of the body on a first side of the plurality of sensor elements. The second sensor holding member is positioned on a second side of the housing and abutted across a portion of a surface of the body of the sensor element on a second side of the plurality of sensor elements.Type: GrantFiled: April 25, 2014Date of Patent: March 7, 2017Assignees: Tyco Electronics Japan G.K., Honda Motor Co., Ltd.Inventors: Takayuki Minematsu, Takanori Nakai, Nobutaka Fukamizu, Kyoji Kitajima
