Abstract
A door lock apparatus with automatic door closing mechanism comprises a latch engaging with a striker secured to a vehicle body, an automatic door closing motor for over-rotating the latch at its half-latched position beyond its full-latched position while the motor rightly rotates, a switch adapated to turn to continuously ON when the latch is between the half-latched and full-latched positions and turn to OFF when the latch is at other position than between the half-latched and full-latched positions, and a controller for rightly rotating the motor when door closing operation turns the switch from its OFF condition to ON condition and reversely rotating motor when the switch turns from ON to OFF.
