Abstract: A lever device may include a movable component including a pair of support arm portions and an operable knob including a base end portion arranged between the pair of support arm portions, the base end portion supported by the pair of support arm portions such that the base end portion is rotatable about a first axis line. The lever device may also include a fixed component including a polar board and a cover arranged in a direction of a second axis line perpendicular to the first axis line, the movable component supported by the fixed component such that the movable component is rotatable about the second axis line within the fixed component. The lever device may further include arc-shaped guide grooves. The pair of support arm portions may respectively include projections that engage the guide grooves.

Abstract: A lever device in which a lid is mounted to an opening portion of a lever member without dropping down therefrom and with a good visual quality is disclosed. The lever device comprises a lever member swingably supported in a fixed system, an opening portion provided in the lever member to open in a radial direction, and a lid that is engaged to the opening portion to cover the opening portion therewith, wherein the lid is provided with a thin portion. Deflections are generated in such a manner as to concentrate on the thin portion of the lid.
