Abstract

An vehicle door latch apparatus includes an engaging mechanism unit and an operating mechanism unit. The operating mechanism unit includes a motor; a worm wheel being rotated by the motor; a sector gear meshing with a pinion provided on one side of the worm wheel and rotating to an unlocking position and a locking position; switch levers connected to the sector gear and shifting to an unlocking position where engagement with a meshing mechanism is releasable and a locking position where the engagement cannot be released; and a key sub-lever pivotally supported on the same pivot on which the sector gear pivots. The key sub-lever is rotatable from a neutral position in an unlocking direction and a locking direction in synchronism with operation of a key cylinder so as to rotate the sector gear to the unlocking position by rotating in the unlocking direction and to rotate the sector gear in the locking direction by rotating in the locking direction. The operating space for operating the key sub-lever can be encapsulated in the operating space for operating the sector gear, thus, it is able to reduce the front projection area and the size of the operating mechanism unit.

Description

[0001] This application claims priority from Japanese Patent Application No. 2007-328659 filed on December 20, 2007, the entire subject matter of which is hereby incorporated by reference. technical field [0002] The present invention relates to a vehicle door latch apparatus including an engaging mechanism unit and an operating mechanism unit capable of controlling the engaging mechanism unit. Background technique [0003] A vehicle door latch apparatus includes an engaging mechanism unit engageable with and disengageable from a striker on a body side, and an operating mechanism unit capable of controlling the engaging mechanism unit. For example, a related vehicle door latch apparatus disclosed in JP-A-2005-282221 includes an operating mechanism unit having a key lever operated so as to follow the operation of a key cylinder provided on the outside of the door, a key link and a key sub-lever; a sector gear operated to rotate following the motor; a lock lever connected to ...
