A gyration type exercising device includes a gyration unit (10), a damper (20) and a drive handle (30). The gyration unit includes a mounting frame (11) and a rotation wheel (12) rotatably mounted on the mounting frame and driven by the drive handle. The rotation wheel is provided with a rotation shaft (121). The drive handle has a first end pivotally connected with the rotation wheel and a second end provided with a holding bar (31). Thus, when the user's two hands hold the holding bar to move the drive handle in a gyration manner, the user's body has to move forward and backward and has to exert a force on the drive handle successively to rotate the rotation wheel reciprocally so as to exercise the user's body completely.
