PURPOSE: To prevent a connecting cord from being broken, by installing an accommodation part for the connecting cord at an installation part where a display body is supported in turnable manner in the longitudinal direction of a screen, in an augularly variable installation mechanism for an on-vehicle TV receiver.

CONSTITUTION: A cord arm 12 is installed in turnable manner in the directions of arrows E-F on the shaft 3d of a bracket 3 for installing a display body. A fixing part 12b for a cord 9 is installed at one edge of the cord arm 12, and the connecting cord 9 is fixed, and a spring 19 is installed at the other edge. The other edge of the spring 19 is engaged with the shaft 3d of the body 1, and urges the cord arm 12 so as to be turned in the clockwise direction around the shaft 3d. With this constitution, the display body 1 is turned, for example in the A direction, and if the connection cord 9 is pulled, the cord arm 12 is pulled in the F direction, and follows the pulling. If the display body 1 is returned to an original position, the cord arm 12 is turned in the E direction by the force of the spring 19, and the cord 9 is retraction-accommodated.
