  • Patent number: 11920674
    Abstract: In this shift device, in a case in which an external force has acted on a lever when an operating mechanism is causing the lever to pivot, a clutch mechanism permits rotation of a first detent plate with respect to a second detent plate, such that pivoting of the lever is permitted. Note that a restraining mechanism urges the lever toward a shift position. This enables to the restraining mechanism to urge the lever separately to the clutch mechanism, thereby enabling the degrees of freedom for setting a biasing load on the lever by the restraining mechanism to be increased.

  • Patent number: 11364798
    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.

  • 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.

  • Patent number: 10372153
    Abstract: A lever device includes a housing and a lever unit pivotally coupled to the housing. The lever unit includes a lever shaft and a pivot shaft that extends in a direction intersecting the lever shaft. The pivot shaft functions as a pivot axis of the lever unit when the lever is pivoted in a first direction. The housing includes a retainer that accommodates the pivot shaft. The pivot shaft includes first and second guides. The first guide slides on the retainer when the lever unit is pivoted in the first direction to permit movement of the lever unit. The second guide that slides on the retainer when the lever unit is operated in a second direction to permit movement of the lever unit.

  • 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.
