An elevation apparatus is provided for an armrest. The elevation apparatus includes a support, a stationary element, a movable element and a latch. The stationary element is supported on the support. The stationary element includes a series of holes overlapping one another, thus forming a pair of teeth between adjacent two of the holes. The movable element is movably connected with the stationary element for supporting the armrest. The movable element defines a hole. The latch includes a thick portion longitudinally inserted in the hole of the movable element and a thin portion transversely movable past the pairs of teeth. The latch is movable between a locking position and a releasing position. In the locking position, the thick portion is in one of the holes of the stationary element. In the releasing position, the thin portion is in the series of holes of the stationary element.
