It is configured to be elastically restored after being rotated in one direction by), the latch gear 120 can form a restrained state of two stages by the binding of the pool 130, 1 by the pool 130 However, the latch gear 120 in the restrained state is forcibly switched in one direction by the electric rotational force generated by the actuator 150, and is configured to be converted into a two-stage restrained state.

Referring to the drawings showing a preferred embodiment, one side of the base plate 110 of the power tailgate latch 100, the opening 110a for entering the striker is formed, the upper surface of the latch shaft ( 111) and the pole shaft 112 is provided, the overall appearance is made of a shape bent in an L-shape.

In addition, a U-shaped hole 120a into which a striker (not shown) fixed to a vehicle body enters is formed in the latch gear 120 installed on the latch shaft 111 of the base plate 110. The first stage fastening portion 121 bent in a b-shape is formed near the inlet of the hole 120a, and the second stage fastening portion 122 bent in a c-shape is also formed at the end of the hole 120a into which the striker enters. It is configured to be bound by the foam 130 to form a one-stage restraint state or a two-stage restraint state.
