To switch between two-wheel drive and four-wheel drive after simplifying structure.SOLUTION: A drive mode switching mechanism comprises: a case which rotates integrally with an input shaft, and an inside space of which is formed as an oil filling space; a driven-side clutch part rotated integrally with the case in the oil filling space; a screw rotated by a driving force of a power source transmitted through an output shaft in the oil filling space, made movable in a direction to/from the output shaft, and moved in a direction separating away from the output shaft by the output shaft rotated at a specific speed higher than the input shaft; a drive-side clutch part rotated integrally with the screw in the oil filling space, and moved in a direction to/from the driven-side clutch part in response to a movement of the screw; and a transmission action part energizing the screw and the drive-side clutch part in a direction approaching the output shaft, and transmitting the driving force of the power source transmitted to the output shaft to the screw.SELECTED DRAWING: Figure 3

    【課題】 構造の簡素化を図った上で2輪駆動と4輪駆動の切替を行う。【解決手段】 入力軸と一体になって回転されると共に内部空間がオイル充填空間として形成されたケースと、オイル充填空間においてケースと一体になって回転される従動側クラッチ部と、オイル充填空間において出力軸を介して伝達される動力源の駆動力によって回転されると共に出力軸に離接する方向へ移動可能にされ出力軸が入力軸より一定以上の高速で回転されることにより出力軸から離隔する方向へ移動されるスクリューと、オイル充填空間においてスクリューと一体になって回転されると共にスクリューの移動に伴って従動側クラッチ部に離接する方向へ移動される駆動側クラッチ部と、スクリューと駆動側クラッチ部を出力軸に近付く方向へ付勢すると共に出力軸に伝達された動力源の駆動力をスクリューに伝達する伝達作用部とを備えた。【選択図】図3
