Abstract

The housing (10) has a housing part (14) and a bearing device (19), which is provided with a bearing race (18) that is partially formed by the housing part. An output shaft of an internal combustion engine is supported at the bearing race in rotary manner around a rotational axis relative to the housing part. The bearing device has another bearing race (22), at which an adjusting shaft is supported in rotary manner around another rotational axis relative to the housing part. The both bearing races are divided in a common plane (28).
