Patent number: 10378647Abstract: A shift lever device includes: a lever main-body; a hollow knob provided at a lever main-body distal end portion; a shift-button rotatably mounted to the knob; and a rod that is inserted-through interior of the lever main-body. The shift-button has a contact surface extending in direction of being away from a rotating-shaft of the shift-button, and that, when the shift-button rotates with respect to the knob, contacts an upper end portion of the rod and lowers the rod. Given that direction orthogonal to axial-direction of the rotating-shaft on plane orthogonal to axis of the rod is reference-direction, and that, among tangent-lines at contact points of the contact surface and the rod, tangent-line on plane orthogonal to the rotating-shaft is reference tangent-line, rotation range of the shift-button is set such that, partway through rotation, the reference tangent-line passes position at which the reference tangent-line becomes parallel to the reference-direction.Type: GrantFiled: December 15, 2016Date of Patent: August 13, 2019Assignee: KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Shori Kato, Etsuo Shimizu, Takayoshi Kitahara, Hironori Mizuno, Saburo Kato, Takaaki Fukushima, Hideaki Ito, Takayoshi Masuda

Patent number: 10184557Abstract: Shift device for vehicle includes housing and shift lever. Shift lever includes cylindrical shaft portion which proximal end is pivotably supported inside housing, cylindrical shaft portion having elongated holes extending through peripheral wall of cylindrical shaft portion and are elongated in longitudinal direction of cylindrical shaft portion, shift knob fixed to distal end of cylindrical shaft portion, detent pin inserted through elongated holes in state where both ends of detent pin protrude from corresponding elongated holes, detent rod inserted in cylindrical shaft portion, detent rod being configured to transmit operating force of operating button in shift knob to detent pin, and shift lock member. Detent pin is fitted to detent rod. When operating button has been operated in state where brake depression operation is not performed, shift lock member contacts with one end of detent pin to block movement of detent pin.Type: GrantFiled: May 23, 2016Date of Patent: January 22, 2019Assignees: TOYOTA JIDOSHA KABUSHIKI KAISHA, TSUDA INDUSTRIES CO., LTD., KABUSHIKI KAISHA TOKAI RIKA DENKI SEISAKUSHO, MANNOH INDUSTRIAL CO., LTD.Inventors: Shori Kato, Etsuo Shimizu, Takayoshi Kitahara, Saburo Kato, Hironori Mizuno, Takayoshi Masuda, Hideaki Ito

Patent number: 7690233Abstract: A portable device includes a main body, which has a mechanical key retainer, and a mechanical key, which is removably retained in the mechanical key retainer. An engagement projection extends from the mechanical key in a direction perpendicular to the direction in which the mechanical key is inserted into the mechanical key retainer. The engagement projection is formed from a resilient material. The mechanical key retainer includes an engagement recess for engaging the engagement projection when the mechanical key is retained in the mechanical key retainer. This structure reduces the size of the portable device and improves portability of the portable device.Type: GrantFiled: August 29, 2006Date of Patent: April 6, 2010Assignee: Kabushiki Kaisha Tokai Rika Denki SeisakushoInventors: Toshiharu Katagiri, Takumi Tamezane, Katsushi Miwa, Jun Yamaguchi, Hironori Mizuno, Makoto Yamamoto, Takao Ogimoto

Publication number: 20080190157Abstract: A downsizable cover structure for a key cylinder is in such that the key cylinder 1 having a key slot 1a is provided on the door 2 of a vehicle. The key cylinder 1 is disposed on a cylinder holder 4 to which a cover 6 having a plate-like shutter 5 on one end thereof is slidably attached. When the cover 6 is slid out so as to be retracted from the key cylinder 1, the shutter 5 passes over the key cylinder 1, whereby the key cylinder 1 is exposed on the cylinder holder 4 so that a key 20 may be inserted into the key slot 11a. When the restriction of the shutter 5 is removed after the unlocking/locking operation, the shutter 5 is transferred due to the urging force of a spring in the direction wherein the key cylinder 1 is closed.Type: ApplicationFiled: February 14, 2008Publication date: August 14, 2008Applicant: KABUSHIKI KAISHA TOKAI RIKA DENKI SEISAKUSHOInventor: Hironori MIZUNO
