  • Patent number: 9127761
    Abstract: A guide plate for a shift lever device, which is formed in correspondence with a movement range of a momentary type shift lever that automatically returns to a home position after being operated, is provided with an elastic member that includes an operation hole. The elastic member restricts the movement range of the shift lever and guides movement of the shift lever. An impact absorption mechanism is formed in the elastic member and absorbs impact of the shift lever when the shift lever automatically returns to the home position. The impact absorption mechanism includes a slit arranged proximal to the operation hole. A seat that is capable of absorbing impact of the shift lever is arranged closer to the operation hole than the slit. A stopper arranged at a back side of the seat relative to the slit supports inwardly curved deformation of the seat.

  • Patent number: 9003916
    Abstract: A support structure for a shift lever includes a rotation shaft coupled to the shift lever, a base plate including a support that pivotally supports the rotation shaft to tiltably support the shift lever, a restriction member coupled to the base plate, and a fixing portion that fixes the restriction member to the base plate. The base plate includes a guide that guides the coupling of the restriction member to the base plate. The rotation shaft includes a main protrusion, which protrudes from an end surface of the rotation shaft in an axial direction, and an auxiliary protrusion, which protrudes in the axial direction from the end surface by a smaller protrusion amount than the main protrusion. The restriction member is fixed in contact with the main protrusion so that the restriction member cooperates with the support to restrict movement of the rotation shaft in the axial direction.
