an arm portion for carrying a head with at least one of a reflective element, a display element, and a camera, the arm portion being pivotable relative to the base portion around a bolt, the bolt providing a pivot axis, extending through an opening of the base portion and an opening of the arm portion, and fixed within the base portion; a sequence of a first base plate part, a second base plate part, and a spring; and a bearing part which is inserted into the opening of the arm portion; wherein the spring applies an axial force to the second base plate part pressing the second base plate part against the first base plate part, wherein the first base plate part applies a radial spreading force against at least one radial outer wall portion of the second base plate part, holding the second base plate part against the bearing part, wherein the second base plate part has a conical shape with a first abutting surface oriented towards the first base plate part, a second abutting surface oriented towards the spring, and a central opening for accommodating the bolt, wherein the second base plate part comprises a first circular groove in the first abutting surface which is complementary to a bracing element formed as a circular shaped ridge of the first base plate part, wherein the at least one outer wall portion of the second base plate part is flexible, and wherein as a result of the axial force applied by the spring, the bracing element of the first base plate part is pressed into the first circular groove of the second base plate part and this forces the at least one flexible outer wall portion of the second base plate part radially outwards and secures the second base plate pan against the bearing part. ### Claim 2 (depends on 1) The rear view device according to claim 1, wherein the second base plate part comprises a second circular groove in the second abutting surface for accommodating the spring. ### Claim 3 (depends on 1) The rear view device according to claim 1, wherein the spring is at least one of arranged coaxially around the bolt between the base portion and the arm portion and supported against a second flange of the base plate part by means of a washer plate. ### Claim 4 (depends on 1) The rear view device according to claim 1, wherein the arm portion comprises a pivot joint portion which at least one of comprises a detent ramp with at least one detent and provides the opening of the arm portion. ### Claim 5 (depends on 4) The rear view device according to claim 4, wherein the pivot joint portion provides the opening of the arm portion and is arranged coaxially with the bolt to interlock with the detent ramp. ### Claim 6 (depends on 1) A motor vehicle comprising a rear view device according to claim 1. ### Claim 7 A method for assembling a rear view device, comprising: providing the rear view device, comprising: a base portion mountable to the motor vehicle; an arm portion for carrying a head with at least one of a reflective element, a display element, and a camera, the arm portion being pivotable relative to the base portion around a bolt, the bolt providing a pivot axis, extending through one or more openings of the base portion and an opening of the arm portion, and fixed within the base portion; a sequence of a first base plate part, a second base plate part, and a spring; and a bearing part which is inserted into the opening of the arm portion; wherein the spring applies an axial force to the second base plate part pressing the second base plate part against the first base plate part, wherein the first base plate part applies a radial spreading force against at least one radial outer wall portion of the second base plate part, holding the second base plate part against the bearing part, wherein the second base plate part has a conical shape with a first abutting surface oriented towards the first base plate part, a second abutting surface oriented towards the spring, and a central opening for accommodating the bolt, wherein the second base plate part comprises a first circular groove in the first abutting surface which is complementary to a bracing element formed as a circular shaped ridge of the first base plate part, wherein the at least one outer wall portion of the second base plate part is flexible, and wherein as a result of the axial force applied by the spring, the bracing element of the first base plate part is pressed into the first circular groove of the second base plate part and this forces the at least one flexible outer wall portion of the second base plate part radially outwards and secures the second base plate pan against the bearing part; providing the base portion of the rear view device having a first flange with a first opening of the one or more openings and a second flange with a second opening of the one or openings, the second opening being threaded; providing the arm portion of the rear view device with a pivot joint part having a further opening; arranging the base portion and the arm portion in a manner for the openings of the base portion and the arm portion to coincide along the pivot axis; providing a pre-assembly arrangement including at least the bolt, with the first base plate part, the second base plate part and the spring being arranged coaxially around the bolt, wherein the second base plate part is adapted to radially expand upon compression in the axial direction of the bolt; and inserting the pre-assembly arrangement through the first opening of the base portion and the further opening of the arm portion and fastening the bolt within the threaded second opening of the base portion thereby compressing the second base plate part in the axial direction of the bolt.
