Abstract
When a telescopic gear baseand a telescopic gear memberare relatively brought close to each other, although their centers shift from each other, even when a tooth tip of a tooth (first tooth)on one surface and a tooth tip of a tooth (second tooth)on one surface contact with each other (at C-point in FIG.()), the telescopic gear baseand the telescopic gear membercan continue the relative movement in direction of an arrow (FIG.()) 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 baseand the telescopic gear memberintermesh gradually to slide, the toothand the toothreadily intermesh during slide (at D-point in FIG.()).
