Abstract
A vehicle door latch device comprises an open lever (24) for connection to an outside open handle (25), a lock lever (34) for connection to an inside lock button (36) through a rod (101), an over-center spring (42) for elastically keeping the lock lever (34) in one of an unlocked position (U) and a locked position (L), a double action mechanism (27) for connection to an inside open handle (28), and an antitheft mechanism (100) having an antitheft spring (105) with elasticity weaker than elasticity of the over-center spring (42). The antitheft spring (105) is arranged to be compressed without displacing the lock lever (34) from the locked position (L) to the unlocked position (U) when the rod (101) is moved in an unlocking direction by an illegal access while the lock lever (34) is being in the locked position (L).
