Abstract: The present invention relates to a cradle for an automobile. A cradle for an automobile according to the present invention comprises a mounting bracket having a front surface to which a device for an automobile is mounted; a link frame provided with a spherical head portion pivotally coupled to the mounting bracket so that the link frame is selectively folded with respect to a rear surface of the device; and a suction plate rotatably installed to a portion of the link frame opposite to a position on which the head portion is provided, the suction plate being selectively attached to a bottom surface. According to the present invention as described above, the cradle is carried or kept in a state where the cradle is folded with respect to the device. Thus, there is an advantage in that the overall volume of the cradle and device for an automobile is reduced.
