Publication number: 20050246867Abstract: A tightening band used for fixing, for example, a cover for protecting a joint of a rotary shaft of an automobile, and a method for producing the same. The tightening band realizes an improved workability of attachment, a proper tightening strength, a wider applicable range of members to be tightened, and a stable tightening strength lasting for a long time. In the tightening band, a pattern of projections and depressions is formed on the surface of each component. Preferably, the pattern is formed by providing depressions, each having a depth of 2 ?m to 30 ?m, on the surface of a band main body, a lever plate, and a lever-plate fixing member.Type: ApplicationFiled: July 9, 2003Publication date: November 10, 2005Applicant: Kentaro NAGATAInventor: Kentaro Nagata

Patent number: 6681878Abstract: In an axle assembly, a differential gear device includes a ring gear and a differential cage. The ring gear has a gear portion formed on a first side surface thereof, which first side surface faces the input shaft and is positioned along the axis of the driving axles, for being operatively connected with the input shaft, and forms an axle hole through which an inner end of one of the right and left driving axles relatively rotatably passes. The differential cage is relatively non-rotatably connected with the ring gear via a second side surface of the ring gear, which second side surface faces away from the input shaft and is positioned along the axis of the driving axles. The differential case also forms therein an axle hole through which an inner end of the residual one of the right and left driving axles relatively rotatably passes, so that the inner ends of the right and left driving axles face to each other.Type: GrantFiled: April 8, 2002Date of Patent: January 27, 2004Assignee: Kanzaki Kokyukoki Mfg.
