図5は、テーブルの高さ調整時における調整筒(18)の回転操作で、調整筒(18)の上端面(18a)と拡径段部(22a)との間の間隔(b)を、最低高さ位置における間隔(a)より大とした状態を示している。
なお、このテーブルの高さの最大調整範囲は、車輪支持体(7)の下端面(7a)とEリング(12)との間の遊び間隔(W)により制限するようにしてある。すなわち、この遊び間隔(W)を、キャスタ軸(6)の大径雄ねじ部(17)に対する調整筒(18)の雌ねじ部(19)の可動範囲より小とすることにより、テーブルの高さを最大としたとき、Eリング(12)が車輪支持体(7)の下端面(7a)に当接して、調整筒(18)の雌ねじ部(19)がキャスタ軸(6)の大径雄ねじ部(17)から外れないようにしてある。
FIG. 5 shows the interval (b) between the upper end surface (18a) of the adjustment cylinder (18) and the enlarged diameter step portion (22a) by rotating the adjustment cylinder (18) when adjusting the height of the table. A state where the distance is larger than the interval (a) at the minimum height position is shown.
The maximum height adjustment range of the table is limited by the play interval (W) between the lower end surface (7a) of the wheel support (7) and the E ring (12). That is, by making this play interval (W) smaller than the movable range of the female threaded portion (19) of the adjusting cylinder (18) relative to the large-diameter male threaded portion (17) of the caster shaft (6), the height of the table can be reduced. When the maximum is reached, the E-ring (12) contacts the lower end surface (7a) of the wheel support (7), and the internal thread portion (19) of the adjustment cylinder (18) is the large-diameter external thread portion of the caster shaft (6). (17) so as not to deviate.
