PURPOSE: To enable a grip device to be properly fitted to palms at the time of grasping same by forming the grip device with a cylindrical or a column-shaped body having nearly a triangular section and a closed outer peripheral face in which a plurality of curved faces or curved and flat faces are continuously connected.

CONSTITUTION: When the captioned handle is applied to the handle of an automobile, a main curved surface (the portion of a segment a-b) of which the center 01 of a curvature R1 is placed nearly in the vicinity of the center of gravity of the section of the handle is connected to a curbed surface (the portion of a segment c-d) of the minimum curvature R3 by means of a sub-curved surface (the portion of a segment a-e) of the maximum curvature +R4. Also, a recessed curved surface (the portion of a segment d-e) of a curvature -R5 is formed between the sub-curved surface and the curved surface of the minimum curvature R3. In this case, the centers 01, 02, 03 of each curvature of the main curved surface, sub-curved surface and the curved surface of the minimum curvature are placed in a triangular shape with the apex angle of the center 01 of the main curved surface being in an obtuse angle. The whole is formed into a ring shape with the projecting curved surface side of the maximum curvature nearly as the outer periphery while the recessed curved surface side being nearly as the inner periphery.
