To provide a wheel device for a moving body in which a step difference part can be climbed over easily.SOLUTION: A double-lever mechanism of a four-section link mechanism is constituted by a main frame serving as a fixed link 11, a driven link 12, an intermediate link 13 and a motor link 14. A main wheel 21 is mounted in an intermediate part of the motor link 14, and a secondary wheel 22 is mounted in the proper position of the driven link 12, and thereby the wheel device 1 for the moving body is constituted. When getting over the step difference part 50, a bottom end of the motor link 14 is pushed backward by an effect of the double-lever mechanism of the four-section link mechanism. Thereby, a front part of the driven link 12 is rotated downward through the intermediate link 13, and the secondary wheel 22 mounted in this is moved downward and is brought into abutment with the upper surface 52 of the step difference part. The wheel device 1 is lifted centering on a pressure contact point of the secondary wheel 22 and the upper surface 52 of the step difference part. Thereby, the main wheel 21 is made to easily rise from the ground and it is structured to get over the step difference part 50.SELECTED DRAWING: Figure 1

    【課題】段差部を楽に乗り越えられる移動体用車輪装置を提供する。【解決手段】固定リンク11となる主フレームと従動リンク12、中間リンク13及び原動リンク14で4節リンク機構の両てこ機構を構成し、原動リンク14の中間部に主車輪21を取り付け、従動リンク12の適所に副車輪22を取り付けて移動体用車輪装置1を構成し、段差部50を乗り越える際には4節リンク機構の両てこ機構の作用により原動リンク14の下端部が後方に押されることで、中間リンク13を介して従動リンク12の前部を下方に回転させ、これに取り付けられている副車輪22も下方に移動させて段差部上面52に当接させ、副車輪22と段差部上面52との圧接点を中心にして当該車輪装置1を持ち上げ、主車輪21を地面から楽に浮き上がらせて段差部50を乗り越える構造にした。【選択図】 図1
