1. A movable apparatus, wherein an imaging device including an optical system forming an optical image having a low resolution region near an optical axis and a high resolution region outside the low resolution region on a light reception surface of an imaging element is installed at an installation position for imaging at least one of a horizontal direction in a rear of one side of the movable apparatus, one direction in a left-right horizontal direction behind a driver seat of the movable apparatus, and a downward direction behind the movable apparatus, with the high resolution region of the optical system, and

wherein, for the imaging device, when an angle of the optical axis direction from the vertical direction when the movable apparatus is viewed from the side is φv, an angle of view of the high resolution region is θv, an angle of view of the low resolution region is θlv, a distance between a viewpoint position of a driver and the installation position is x, a height of the installation position is h 1 , a distance from the viewpoint position to a tip of the movable apparatus is d 0 , a length of the movable apparatus is d 8 , a distance from the movable apparatus to a predetermined position on the front side to be checked in the rear is d 10 , a distance from the movable apparatus to a predetermined position on the distant side to be checked in the rear is d 11 , a width of the movable apparatus is w 6 , a height of a target object to be checked behind the movable apparatus is h 3 , and a distance between the installation position and the side of the movable apparatus is z,

φ v−θv−θlv ≤−Atan(( d 8− d 0− x+d 10)/ h 1)≤φ v+θv+θlv

(when h 1≥ h 3)

φ v−θv−θlv ≤−Atan(( d 8− d 0− x+d 11)/( h 1− h 3))≤φ v+θv+θlv

(when h 1< h 3)

φ v−θv−θlv ≤−Atan(( h 3− h 1)/( d 8− d 0− x+d 11))−90°≤φ v+θv+θlv
