An object of the present invention is to provide a rotary drive system and an engine which have greater toughness and which are capable of smoothly converting linear thrust force into rotary torque. In the present invention, a pair of elongated members (16a, 16b) are arranged parallel in a first direction (X). A moving guide (22) is spanned between the elongated members (16a, 16b), arranged in a second direction (Y) perpendicular to the first direction (X), and capable of moving in the first direction (X). A moving body (24) is capable of moving in the second direction (Y) along the moving guide (22). A rotary shaft (36) is capable of rotating about an axial line, which is perpendicular to the first direction (X) and the second direction (Y). A lever (38) has one part (38c), which is pivotably connected with the moving body (24), and another part (38d), which is fixed to the rotary shaft (36), whereby the lever rotates the rotary shaft (36) when the moving body (24) moves round. A driving mechanism (41, 42, 45, 46) moves the moving guide (22) in the first direction (X). A control mechanism (50, 51) stabilizes rotational speed of the rotary shaft (36). <IMAGE> |
