Abstract

An automotive door latch device is provided with a latch which rotates by being pushed into motion by a striker; a latch return spring which applies force to the latch in the direction of the return position; a pawl which engages with the latch and prevents the same from rotating in the door opening direction (in the direction of the return position); and a pawl return spring which applies force to the pawl in the direction of the return position. A housing section, which belongs to the body and houses the latch and the pawl, opens downward at a location which is at one side of the body and is below the pawl. A pawl return spring is mounted on a spring mounting section formed at a location which is at the other side of the body and is away and downward from the rotation support section of the pawl. The pawl side end of the pawl return spring engages with the pawl via a through hole provided in the body. Due to the above, it is possible to enhance the discharging of powder dust or the like intruding inside the housing section, which belongs to the body and houses the latch and the pawl, outside the body.
