ABSTRACT:
When a telescopic gear base6and a telescopic gear member8are relatively brought close to each other, although their centers shift from each other, even when a tooth tip of a tooth (first tooth)6aon one surface and a tooth tip of a tooth (second tooth)8aon one surface contact with each other (at C-point in FIG.5(b)), the telescopic gear base6and the telescopic gear member8can continue the relative movement in direction of an arrow (FIG.5(b)) from such the state, because they contact with each other and intermeshed so that each angle with their tooth continuing directions is set larger than 0° and smaller than 90°. Therefore, since the telescopic gear base6and the telescopic gear member8intermesh gradually to slide, the tooth6aand the tooth8sreadily intermesh during slide (at D-point in FIG.5(c)).
