Publication number: 20130228032Abstract: A steering device provides a driver operation feeling that lets the driver definitely feel that a movable tilt lock gear and a fixed tilt lock gear are securely engaged. Gear noise in tilt adjustment when the movable tilt lock gear and the fixed tilt lock gear are engaged halfway is prevented. As the control force of an operating lever is rapidly decreased when a fitting protrusion is fitted to a stepped part, a click and click stop feeling occur and a definite operation feeling that the clamping is securely performed is acquired. As the fitting protrusion is integrated with the operating lever and a sliding surface configured by a groove, an inclined face and the stepped part are also formed as an outside face of the fixed tilt lock gear, the number of parts and man-hours for assembly can be reduced.Type: ApplicationFiled: August 29, 2011Publication date: September 5, 2013Applicant: NSK Ltd.Inventor: Shinji Okada

Publication number: 20130104688Abstract: A steering device reduces a sliding sound and an impact sound between a movable tilt lock gear and an outer surface of a side plate of a vehicle body attachment bracket. When a movable tilt lock gear is rotated, and a thread of an inclined cam surface of a stationary cam runs on a thread of an inclined cam surface of a movable cam, a fastening rod is pulled toward a left side, and the movable tilt lock gear is pushed toward an outer surface of a left side plate. Because a first buffer member and a second buffer member are attached to the movable tilt lock gear, sliding surfaces of the first buffer member and a sliding surface of the second buffer member contact the outer surface of the left side plate, and slide, to suppress the sliding sound.Type: ApplicationFiled: July 14, 2011Publication date: May 2, 2013Applicant: NSK Ltd.Inventors: Shinji Okada, Yuuichi Tomaru

Publication number: 20130104687Abstract: A steering device smoothly moves a variable tilt lock gear in a tilt direction, smoothly engages the movable tilt lock gear with a stationary tilt lock gear, and facilitates the assembling. When a movable tilt lock gear is not well engaged with a stationary tilt lock gear, and the respective threads of a gear of the movable tilt lock gear and a gear of the stationary tilt lock gear are abutted against each other, arm parts of a wire spring are elastically deformed by its reaction force. As a result, the movable tilt lock gear is slightly moved in the vertical direction of the vehicle body while the stationary cam is fixed, and the gear of the movable tilt lock gear and the gear of the stationary tilt lock gear are normally engaged with each other.Type: ApplicationFiled: July 14, 2011Publication date: May 2, 2013Applicant: NSK Ltd.Inventors: Shinji Okada, Yuuichi Tomaru

Publication number: 20130047773Abstract: A steering device is provided that includes an aluminum-alloy column bolted with a steering lock apparatus, that prevents destruction of a flange to be bolted, and that prevents the bolt from being loosened by applying shock to a bolt head section through the use of a special tool. A counterbore is formed so deep that a slant plane is higher than a top end of a disk-shaped member of a bolt. A thief can hardly apply shock to the disk-shaped member of the bolt using a special tool. It is difficult to rotate and loosen the bolt. A vehicle can be prevented from being stolen by removing a steering lock apparatus from an outer column.Type: ApplicationFiled: October 21, 2010Publication date: February 28, 2013Applicant: NSK Ltd.Inventors: Yuuichi Tomaru, Shinji Okada, Daiki Orihara

Publication number: 20120266715Abstract: A steering device facilitates the assembling of a tilt lock mechanism that elastically supports movement of a movable tilt lock gear to a stationary cam in a tilt direction by a spring. The stationary cam has both characteristics of durability and an impact reduction capability. When a cylindrical part of a tilt stopper has been inserted into a through hole, the cylindrical part is enlarged in diameter, and engagement surfaces of engagement projections are engaged with an end surface of an inclined cam surface side of a stationary cam. A right end surface of a flange part of the tilt stopper is abutted against an end surface of a movable tilt lock gear. The movable tilt lock gear, a wire spring, and the stationary cam are integrated by the tilt stopper, and those four parts can be prevented from being dispersed during transportation. As a result, the assembling time can be reduced.Type: ApplicationFiled: July 14, 2011Publication date: October 25, 2012Applicant: NSK Ltd.Inventors: Shinji Okada, Yuuichi Tomaru

Publication number: 20110308464Abstract: Processing gas is supplied from the central upper part of a processing chamber to a wafer on a mounting board, while the processing chamber is exhausted from processing gas exhaust passages at areas outside of the wafer. In addition, purge gas is supplied from purge gas supply passages to a buffer chamber formed between the peripheral part of a container main body and that of a cover body. The supplied flow-rate of the processing gas is made less than the exhaust flow-rate in the processing gas exhaust passages. Accordingly, the purge gas in the buffer chamber is drawn into the processing chamber via a purge gas supply hole formed of a gap between the container main body and the cover body due to a negative pressure inside the processing chamber caused by a difference between the flow rates.Type: ApplicationFiled: August 26, 2011Publication date: December 22, 2011Applicant: TOKYO ELECTRON LIMITEDInventors: Hiroyuki KUDOH, Hideto Mori, Shinji Okada, Toyohisa Tsuruda
