A bearing position for rotatably mounting a shaft or an axle in a housing. The bearing position comprises a rolling bearing, which is designed as a roller bearing, with a bearing ring, which is assigned to the housing, where said bearing ring forms an outer rolling raceway, which faces radially inwards and on which rolling elements are guided, said rolling elements mutually interacting with a shaft, which forms an inner rolling raceway, or with an inner bearing ring. A polygonal bearing is provided as the roller bearing; and said polygonal bearing encloses a bearing ring with at least one elastic section, which forms a transversely convex raceway curvature. This arrangement guarantees that at least one rolling element is supported and guided in a radially prestressed manner without radial clearance on the rolling raceway.

A securing element () made of sheet metal with an annular body () and with holding tongues () which emerge from the annular body () and end at a hole () in the securing element (), which hole is centered with respect to the center axis () of the securing element (), wherein the hole () leads axially in the same direction as the center axis () through the securing element () and, at radial narrowest hole cross sections of the hole (), is bounded at least by end edges () formed on the end sides of the holding tongues ().

A drag lever for actuating a gas exchange valve of an internal combustion engine. The drag lever includes an oblong lever body formed of sheet metal material, wherein the lever body has a bottom and side walls integrally formed at an angle of about 90&#xb0; onto the bottom on both sides. A first end section of the lever body includes a joint socket formed into the bottom between the side walls. The joint socket serves to pivotally moveably support the drag lever on a joint head mounted stationary in the internal combustion engine. A middle section of the lever body is provided with a cam gripping surface, and a second end section of the lever body has a contact surface extending on the bottom. The contact surface serves for actuating the gas exchange valve. The lever body is dimensioned so as to have essentially the same width in a cross section through the joint socket and in a cross section through the middle section. Starting from the first end section of the lever body, the angle of the side walls increases continually to about 90&#xb0;.
