A strut type suspension device has a retractable strut (111) that connects to an upper portion of an in-wheel motor drive device (10) so as not to relatively move; and a swingable lower arm (116) that is coupled to a lower portion of the in-wheel motor drive device in any direction, and permits vertical swinging of the in-wheel motor drive device and also permits steering of the in-wheel motor drive device about a steering shaft (S) that passes through a coupling point (119) between the lower arm (116) and the in-wheel motor drive device. An axis (M) of the motor portion (21) of the in-wheel motor drive device is arranged above a height of the coupling point (119) of the lower arm (116).
