Abstract
Spiral springs (20) pressing a lift member (30) in an upward direction is arranged so that wound-up portions (20b) thereof move up and down along lift paths (13a, 13b) according as the lift member (30) moves up and down. In each lift path (13a, 13b) is provided a push-fit portion (40) of which a width is narrower than an outer diameter of the wound-up portion (20b) of the spiral spring (20), and in which according as the lift member (30) is lowered, the wound-up portion (20b) is fitted in such a manner that the wound-up portion becomes radially compressed. Accordingly, a cost-efficient and universally applicable display elevation adjusting apparatus can be provided which can make the operation feeling at the time of raising adjustment constant and can attain adjustment to suit the preference.
