Sensor mounting for holding a sensor of a motor vehicle, comprising - a walling that encloses a cavity with a first opening and a second opening and which defines a longitudinal axis, wherein the sensor can be introduced into the cavity by moving it along the longitudinal axis through the first opening and/or through the second opening, - a joining flange disposed in the region of the first opening with which the sensor mounting can be connected to a cladding component of the motor vehicle, thereby forming an open space between the sensor mounting and the cladding component, wherein the sensor mounting can be connected to the cladding component by means of a filling and fixing agent that fills the open space, and - a protuberance disposed on the joining flange and extending along the longitudinal axis, wherein - the joining flange and the protuberance are implemented such that, when the sensor mounting is connected to the cladding component, the filling and fixing agent is forced away from the cavity, characterized in that the joining flange comprises an end face that faces the first opening and that is inclined at an end face angle (α) towards a plane extending vertically to the longitudinal axis, wherein the end face angle (α) faces away from the first opening and is set at between 1° and 7° and, in particular, between 3° and 5°, and/or characterized in that the joining flange comprises an outer surface that is inclined at an outer surface angle (β) relative to the longitudinal axis, wherein the outer surface angle (β) is set at between 1° and 5° and effects a tapering of the joining flange in the direction of the first opening. - a walling that encloses a cavity with a first opening and a second opening and which defines a longitudinal axis, wherein the sensor can be introduced into the cavity by moving it along the longitudinal axis through the first opening and/or through the second opening, - a joining flange disposed in the region of the first opening with which the sensor mounting can be connected to a cladding component of the motor vehicle, thereby forming an open space between the sensor mounting and the cladding component, wherein the sensor mounting can be connected to the cladding component by means of a filling and fixing agent that fills the open space, and - a protuberance disposed on the joining flange and extending along the longitudinal axis, wherein - the joining flange and the protuberance are implemented such that, when the sensor mounting is connected to the cladding component, the filling and fixing agent is forced away from the cavity, characterized in that the joining flange comprises an end face that faces the first opening and that is inclined at an end face angle (α) towards a plane extending vertically to the longitudinal axis, wherein the end face angle (α) faces away from the first opening and is set at between 1° and 7° and, in particular, between 3° and 5°, and/or characterized in that the joining flange comprises an outer surface that is inclined at an outer surface angle (β) relative to the longitudinal axis, wherein the outer surface angle (β) is set at between 1° and 5° and effects a tapering of the joining flange in the direction of the first opening.
