An embodiment of the present invention relates to a parking brake actuator which includes a motor (100); a worm gear (200) connected to the motor (100) to transmit a power; a worm wheel (300) engaged with the worm gear (200); a drive shaft (400) coupled to the worm wheel (300), wherein a parking cable is connected to the drive shaft (400); a power transmission gear (500) including a first gear (510) coupled to a rotational shaft (130, C2) of the motor (100) and a second gear (520) which is coupled to a rotational shaft (C1) of the worm gear (200) and connected to the first gear (510) to transmit the power; and a housing (600) including a first accommodation portion (610) disposed at one side of a reference line (CL) which is formed perpendicular to the rotational shaft (130, C2) of the motor (100) and passes through the first gear (510) to accommodate the motor (100), a second accommodation portion (620) disposed at another side of the reference line (CL) to accommodate the worm gear (200) so that the rotational shaft (C1) of the worm gear (200) is parallel to the rotational shaft (130, C2) of the motor (100), and a third accommodation portion (630) disposed at the other side of the reference line (CL) to accommodate the worm wheel (300), thus providing an advantageous effect in which motors of various sizes may be applied without machining a separate housing to correspond to each of the sizes of motor or changing sizes or the number of teeth of gears.
