  • Patent number: 7444899
    Abstract: A shifting apparatus for an automatic transmission of a vehicle has a shift lever; a push knob (1d) operable in a pushing manner; an erroneous operation preventing window (12); a rod lock pin (1c) adapted to be lowered by the pushing down operation of the push knob (1d); and a lock mechanism operated by the descending motion of the rod lock pin (1c) to release the engagement with the erroneous operation preventing window (12) in order to enable the swing motion of the shift lever (1) from the predetermined position. The lock mechanism includes a pivot member pivotable around a pivot shaft on the shift lever (1) and normally urged toward a side limiting the swing motion of the shift lever (1). The pivot member has a first branch (8b) adapted to engage and disengage the erroneous operation preventing window (12) according to its pivot motion.

  • Publication number: 20070137359
    Abstract: A lever assembly, which can be used as a speed changing apparatus for vehicle, can include an operating lever shaft. The operating lever shaft can be pivotally supported on a speed changing operation unit. An operating knob can be formed with a mounting bore for receiving a top end of the operating lever shaft and can also be adapted to be mounted on the top end of the operating lever shaft for carrying out a speed changing operation of a transmission of vehicle by pivoting the operating lever shaft. An engagement member can have a cylindrical configuration of substantially same inner circumferential configuration as an outer circumferential configuration of the operating lever shaft. The engagement member can be adapted to be received and secured within the mounting bore of the operating knob and can have nails that are elastically deformable by the operating lever shaft and engaged therewith when the operating lever shaft is inserted through the engagement member.
