Patent number: 9920794Abstract: A torque limiter is configured from a ring body and a spring-form part provided in the ring body. The ring body includes a band-form metal plate and is bent approximately into a C-shape along the circumferential direction of a motor shaft and a lock holder. The spring-form part is formed so as to be capable of radial elastic deformation. The spring-form part is configured from main protrusions arranged in a compressed state between the motor shaft and the lock holder, and from sub-protrusions arranged in a non-compressed state. Further, grease is stored in a part or all of the concavities formed by the main protrusions and the sub-protrusions.Type: GrantFiled: July 7, 2015Date of Patent: March 20, 2018Assignees: JTEKT CORPORATION, TOGO SEISAKUSYO CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Toshihiro Asakura, Masatoshi Fujimoto, Toshiaki Ogata, Yukihiko Kanayama, Hirotsune Suzuki, Yuji Nakamura, Yuzo Hirakawa, Kenji Hayashi, Hiroyuki Toyoda

Patent number: 7549503Abstract: In a steering device 10, the upper side portion of a rubber boot 120 is fixedly fitted on a case outer cylindrical component 41 of a cable case 39, and the lower side portion of the rubber boot 120 is fixed to a dashboard 100 of a vehicle body 14 over the entire circumference thereof. Thus, the case outer cylindrical component 41 can be secured against rotation more firmly compared with a prior art steering device wherein such a case outer cylindrical component is fixed at two portions thereon by means of a wire of a V-letter shape. Further, the problem attendant on the wire of the V-letter shape in the prior art steering device no longer arises even in the car models wherein the case outer cylindrical component 41 and the dashboard 100 are relatively far from each other. That is, it can be realized to secure the case outer cylindrical component 41 of the cable case 39 against rotation relative to the vehicle body 14 even in any car model.Type: GrantFiled: August 29, 2005Date of Patent: June 23, 2009Assignees: Jtekt Corporation, Toyota Jidosha Kabushiki KaishaInventors: Yukihiko Kanayama, Kenji Kato, Isao Hasegawa, Kenji Hayashi

Patent number: 7038139Abstract: A spiral cable device is provided with a cylindrical casing, an inner cylinder rotatable relative to the cylindrical casing, and a flexible flat cable connected to the inner cylinder at one end thereof and to the cylindrical casing at the other end thereof. The flexible flat cable has plural leads arranged in a single layer and is folded to form multiple layers of the leads, so that even where the flexible flat cable is to have many leads, the spiral cable device can be made short in the axial direction thereof.Type: GrantFiled: April 23, 2003Date of Patent: May 2, 2006Assignees: Toyoda Koki Kabushiki Kaisha, The Furukawa Electric Co., Ltd.Inventors: Yukihiko Kanayama, Morihiro Matsuda, Junji Kawamuro, Shoichi Shono, Yasunori Okada

Patent number: 6582119Abstract: A temperature sensing apparatus comprises a temperature sensor, a current measuring device and temperature detection circuit. The temperature sensor contains a thermal resistor that is disposed near a motor and outputs voltages acting to the thermal resistor. The current measuring device measures quantity of current that is applied to the motor. The temperature detection circuit detects temperature of the motor according to the output voltages from the temperature sensor. And, the temperature detection circuit judges whether a predetermined quantity of current is applied to the motor during a predetermined time. When the predetermined quantity of current is applied to the motor during the predetermined time, the temperature detection circuit compares a temperature detected by the current measuring device with a predetermined temperature. When the detected temperature is lower than the predetermined temperature, the temperature detection circuit decides a wire of the thermal resistor breaks.Type: GrantFiled: March 13, 2001Date of Patent: June 24, 2003Assignee: Toyoda Koki Kabushiki KaishaInventors: Yutaka Mori, Yukihiko Kanayama, Fukami Imai, Yoshiyuki Shibata, Susumu Koike, Yasushi Yamada
