Abstract: A side mounted vehicular rear view mirror of the type which comprises a hollow tubular steel gooseneck support arm which can be rotated forwardly or rearwardly relative to a clamp type mount on the vehicle body to fold the mirror against the vehicle body side to prevent damage to the mirror in, for example, a vehicle carwash or other narrow passageway. The clamping structure comprises a mount having longitudinally spaced semi-cylindrical bearing seats adapted to receive a length of the gooseneck arm and a spring steel clamp having opposing complemental bearing surfaces and an arcuate detent which engages a straight sides slot formed in the gooseneck arm where it overlies the spaced apart bearing seats. The spring clamp flexes to provide a relatively high break away torque and a relatively low continued rotation torque.
