Patent number: 5894762Abstract: In an automotive pedal support system, an operating member is supported for operation by a support member, and a return spring member is operable to apply a force to the operating member in a direction opposite to the direction in which the operating member can be depressed. A projecting portion is formed on one of the support member and the operating member, and a receiving portion is formed on the other of the support member and the operating member. The projecting portion and the receiving portion are coupled to each other to permit operation of the operating member, and constitute a holding mechanism which is constituted of only two members selected among the support member, the operating member, and the spring member.Type: GrantFiled: April 9, 1997Date of Patent: April 20, 1999Assignee: Tsuda Kogyo Kabushiki KaishaInventors: Tetuya Arao, Michiyuki Murakami, Ryo Tanahashi

Patent number: 5560253Abstract: A shift lever assembly for a manual transmission is disclosed. A boss of a shifting lever is supported for rotation by a shift shaft on a lever retainer. A boss of a selecting lever is supported for rotation by a support shaft parallel to the shift shaft on the lever retainer. A boss of a shift lever is supported for selecting operation about a select shaft at right angles to the shift shaft on the shifting lever. Shifting operation of the shift lever is transmitted via a select arm and an end ball portion thereof to an engagement portion of the selecting lever to cause rotation of the selecting lever about the axis of the support shaft. The shift lever is formed integrally with its boss, the select arm and the ball portion.Type: GrantFiled: June 6, 1995Date of Patent: October 1, 1996Assignee: Tsuda Kogyo Kabushiki KaishaInventors: Koichi Ishikawa, Michiyuki Murakami, Yoshitaka Sogo, Mitsuyuki Hasegawa

Patent number: 5024117Abstract: An apparatus is provided for supporting a shift lever for a transmission the shift lever including a ball-like portion which is on the shift lever and has spherical surfaces of a fixed curvature at least on a part of the lower and upper sides. A receiving surface has a concave spherical surface of nearly the same curvature as the lower spherical surface of the ball-like portion and is in contact with the lower spherical surface, and a retaining surface has a concave spherical surface in surface contact with the upper spherical surface of the ball-like portion and holds the ball-like portion between the concave spherical surface and the receiving surface. A retaining member is installed from above to cover the ball-like portion, and an elastic displacement section is projectingly formed on the lower side of the retaining member to enclose the upper part of the ball-like portion and is elastically deformable in the radial direction of the ball-like portion.Type: GrantFiled: March 21, 1990Date of Patent: June 18, 1991Assignees: Toyota Jidosha Kabushiki Kaisha, Tsuda Industries Company, Ltd.Inventors: Ichiji Yamada, Yutaka Inuzuka, Michiyuki Murakami, George Suzuki, Tyo Tanahashi, Takeshi Kondo

Patent number: 4873884Abstract: A shift lever supporting apparatus for a transmission, has an integral structure comprising a cylindrical shift lever mounting portion for receiving a ball portion of a shift lever, a pyramidal retainer portion contiguously provided below the shift lever mounting portion, a plate portion contiguously provided below the retainer portion, and a bearing portion for mounting a select bell-crank, the bearing portion being contiguously provided on the retainer portion and in close proximity to the shift lever mounting portion. The shift lever mounting portion is provided with a seat surface for supporting the ball portion of the shift lever, and a U-shaped notch which allows insertion of a select lever extending from the ball portion. The ball portion of the shift lever is inserted into the shift lever mounting portion from the upper side and this ball portion is pressed against and thereby retained on the seat surface by the use of a cap.Type: GrantFiled: August 17, 1988Date of Patent: October 17, 1989Assignees: Toyota Jidosha Kabushi Kaisha, Tsuda Industries, Co., Ltd.Inventors: Ichiji Yamada, Yutake Inuzuka, Isao Ichihara, Michiyuki Murakami, George Suzuki, Ryou Yanahashi, Takeshi Kondo

Patent number: 4726249Abstract: A shift lever assembly operatively linked with a transmission, for manually operating the transmission, including a shift lever, a support, and a pair of stationary retainer plates. The shift lever has a handle portion at which the shift lever is manipulated, and a spherical coupling portion at which the shift lever is universally supported. The support consists of two halves in the form of a pair of support sheets which have respective adjoining surfaces substantially parallel to a plane in which the shift lever extends. The support sheets cooperate with each other to provide a spherical support portion which engages the spherical coupling portion of the shift lever for universally supporting the shift lever. Each support sheet has an outer surface opposite to the corresponding adjoining surface. The stationary retainer plates are disposed in spaced-part relation with each other on opposite sides of the support, so as to hold the pair of support sheets at their outer surfaces.Type: GrantFiled: October 10, 1986Date of Patent: February 23, 1988Assignees: Toyota Jidosha Kabushiki Kaisha, Tsuda Industries Co., Ltd.Inventors: Yutaka Inuzuka, Akiyoshi Hirai, Michiyuki Murakami, George Suzuki, Takahiko Watanabe, Takeshi Kondo
