- At least one recessed area is introduced in at least one of the contact surfaces, that is, in the main body contact surface and / or in the pad contact surface, which allows degassing of the adhesive.
- a consideration of the invention is that in the bonding of the
- the at least one recessed area forms a venting structure for the adhesive areas, in particular adjacent to the at least one recessed area.
- a plurality of indentation areas or venting structures which are not interconnected with one another, but also a common recessed area or a common venting structure can be realized.

- the at least one recessed area is at least partially adhesive-free in the radial direction.
- the depression region contains a free-flow which, in terms of flow, preferably extends uninterruptedly over the entire depression region and / or an associated ventilation structure. Due to the fact that the adhesive does not completely fill the depression area, a free volume remains, which preferably communicates with the environment, so that the gas of the adhesive can be discharged via the free volume.

- This embodiment is particularly evident when the base body of a metal and the lining contact surface forming edge layer of Reib Anlagenag stresses is also formed of metal.
- metal foils which are gas-tight are used as carriers for friction layers.
- the advantage of the invention is particularly strong in the foreground, since this combination of adhesive partners with gas-tight contact surfaces were previously not stickable due to the degassing of the adhesive and the resulting disadvantages.
- Gas-tight is preferably understood to mean the property that gases formed during bonding can not or can not be sufficiently dissipated through the contact surfaces and collect between the contact surfaces and have negative effects there, such as reduction of the adhesive strength or impairment of the dimensional stability in addition, one or both contact surfaces pore-free and / or passage-free formed for gases in the radial direction.
- the friction layer carrier device is designed as a brake pad body, in particular a firing disk, a clutch body, in particular a clutch disk, a synchronizer body, in particular a synchronizer ring.
- the friction layer lining body is constructed of at least two layers, wherein a layer is realized as a carrier, in particular a metal strip and / or a sheet metal foil, which carries at least one Reib harshlage, which is formed for example as a sintered friction lining.
- the friction layer support device is a synchronizer ring, optionally as an outer ring
- the synchronizer ring has a conical and / or conical surface as a body contact surface, which preferably occupies an angle between 6 ° and 10 ° relative to the axis of rotation of the synchronizer ring.
- On the main body contact surface is a coated or sintered

- the recessed area presents as a recessed structure opposite the contact surfaces otherwise smoothly formed in the adhesive areas.
- the adhesive agent application is selected such that the at least one depression region is incomplete after the adhesion is filled and / or fluidically permeable remains. This further development underlines the idea that the at least one recessed area forms a continuous venting structure.

- the outer circumference of the main body 2 has a circumferential radially outwardly facing row of teeth 4, which for a cooperation, for example with a
- Gear wheel of a transmission is formed.

- the bonding of the base body 2 with the Reib Anlagenbelag stresses 3 is optionally carried out at elevated temperatures, ie at temperatures greater than 40 ° C, wherein as adhesive, for example, a film adhesive or phenolic resin adhesive is used. During the gluing or curing of the adhesive gases can escape from the adhesive volume, which originate from solvent residues or also from reaction products of the adhesive.
