To reduce the possibility of occurrence of an accident during propulsion in liquid.SOLUTION: A disk-like robot 1 which is a propulsion device propelling in liquid includes: fin muscle units 10 which are a plurality of stick-like members with each member lined up peripherally with tip ends facing outward with intervals as well as being provided to be rotatable in a prescribed range in a direction vertical to the lined up direction with a prescribed positions on the base end side as the rotational axis; an actuator 20 and a central unit which are fin muscle movement units for making the plurality of fin muscle units carry out a reciprocating rotational movement in a prescribed range so that a phase difference occurs between adjacent fin muscle units 10; and film-like units 40 which are a plurality of film-like members with each member connected to each of the adjacent two fin muscle units 10 and provided in portions in between the fin muscle units 10.SELECTED DRAWING: Figure 1
【課題】 液体中の推進において事故を引き起こす可能性を低減する。【解決手段】 円盤状ロボット１は、液体中で推進する推進装置であって、複数の棒状の部材であり、当該部材それぞれが、先端が外側に向けられて間隔を設けて周状に並べられると共に、基端側の所定位置を回転軸として、並べられた方向とは垂直な方向に所定の範囲で回転可能なように設けられるひれ筋部１０と、隣り合うひれ筋部１０間で位相差が生じるように、複数の前記ひれ筋部に所定の範囲で往復の回転運動をさせるひれ筋駆動部であるアクチュエータ２０及び中心部と、複数の膜状の部材であり、当該部材それぞれが、隣り合う２つのひれ筋部１０それぞれに接続されてひれ筋部１０の間隔の部分に設けられる膜状部４０とを備える。【選択図】 図１
