摘要

[Problem] To provide a height adjustment device or the like having a simple structure. [Solution] A height adjustment device (100) is provided with a guide rail (122) that is long and thin in the vertical direction of a vehicle, and a slider assay (120) attached to the guide rail (122) so as to be capable of sliding vertically. The guide rail (122) has a base part (156) extending vertically along a center pillar (116), and rail parts (130a, 130b) provided vertically across the widthwise sides of the base part (156). The slider assay (120) is attached to the rail parts (130a, 130b) from the top ends thereof. The rail parts (130a, 130b) have top-side stopper parts (166a, 166b) formed at the top ends thereof after the slider assay (120) is attached, the top-side stopper parts (166a, 166b) protruding above the sliding trajectory of the slider assay (120).
