  • Patent number: 10458537
    Abstract: In a shift lever device, a lever moves an operation member when the lever is rotationally operated in a front-rear direction, and the lever rotates a select link such that the select link moves the operation member when the lever is rotation operated in a left-right direction. The position of the operation member is detected to detect a shift position of the lever. When the lever is rotation operated in the front-rear direction, the lever therefore moves the operation member without being through the select link, thereby enabling the precision with which the shift position of the lever in the front-rear direction is detected to be raised.

  • Publication number: 20190202288
    Abstract: In a shift device, contact projections of a rotation cylinder make contact with side faces of recesses of an detent plate due to an urging force so as to urge a lever toward a shift position side. The contact projections make line contact with the side faces of the recesses. This enables the contact amount between the contact projections and the side faces of the recesses to be increased, enabling the contact pressure between the contact projections and the side faces of the recesses to be lowered.

  • Publication number: 20190193032
    Abstract: A spunbonded nonwoven fabric has a smooth surface, is highly unlikely to cause a widthwise curl due to a difference between the states of front and back surfaces, has a superior membrane formability of not allowing, at the time of casting of a resin solution, a bleed-through of the resin solution due to excessive permeation, a peel-off of a membrane substance, or any other defect such as nonuniform membrane or pin hole due to fluffing of the support, and further exhibits membrane bondability that is strong enough to prevent the membrane substance from peeling off after membrane formation.

  • Patent number: 10253870
    Abstract: In a shift lever device, a gate pin of a lever is guided by a gate groove of a gate plate, and a detent pin of the lever is abutted on a detent face of a detent block due to an urging force. A sensor mechanism detects a shift position of the lever. The gate plate, the detent block, and the sensor mechanism are disposed at a lower side of the lever, the gate plate and the detent block are disposed at a rear side of the lever, and the sensor mechanism is disposed at a front side of the gate plate and the detent block. This thereby enables a reduction in size of the shift lever device in an up-down direction.
