1. an automobile sun vizor, this automobile sun vizor has visor body and above-mentioned visor body is installed on the bolster of the round section on vehicle body, above-mentioned bolster has the longitudinal axis portion and transverse axis portion that are formed mutually orthogonal shape, above-mentioned visor body rotates freely around the longitudinal axis portion of above-mentioned bolster and transverse axis portion respectively, it is characterized in thatCircumferentially three the region forces also had all only in the transverse axis portion of above-mentioned bolster under using state and receiving state keep the force retaining member in the transverse axis portion of this bolster,Above-mentioned force retaining member is formed by carrying out bending machining to the leaf spring of integrated, and the application force having the bolster retaining zone that is made up of above-mentioned three regions of periphery covering above-mentioned transverse axis portion integrated and leave predetermined distance along the direction intersected with the axis direction in above-mentioned transverse axis portion from this bolster retaining zone produces region;

  • Above-mentioned application force produces the installation portion that region is set to be installed on by above-mentioned force retaining member in above-mentioned visor body,Above-mentioned bolster retaining zone comprises;

    under using state and receiving state, toward each other and bounce-back shape ground clamping above-mentioned transverse axis portion two clamping zones formed by clinoplane;

    And in a state of use with under receiving state, bear the 3rd contact area in above-mentioned transverse axis portion, above-mentioned two clamping zones exert a force towards the 3rd contact area, and the 3rd contact area bears the force of above-mentioned two clamping zones,The normal direction of the clinoplane of above-mentioned two clamping zones is set to towards the 3rd contact area and mutually intersects, above-mentioned two clamping zones and the 3rd contact area in the circumference in transverse axis portion to set roughly at equal intervals,In a state of use, above-mentioned two clamping zones contact with linear contact lay in fact in the axial direction with the abutting in transverse axis portion,On the axis direction in above-mentioned transverse axis portion, the width of a clamping zone in above-mentioned two clamping zones is less than the width of another clamping zone and above-mentioned 3rd contact area,Above-mentioned transverse axis portion has the par of nick shaped in the assigned position of circumferencial direction,When above-mentioned visor body turns to the accepting regions of regulation around above-mentioned transverse axis portion, an above-mentioned clamping zone contacts with the par in above-mentioned transverse axis portion, above-mentioned visor body is held in this accepting regions, when above-mentioned visor body turns to the region beyond above-mentioned accepting regions, an above-mentioned clamping zone contacts with the circular portion in above-mentioned transverse axis portionThe above-mentioned force retaining member processed by the plate-shaped spring bends of integrated comprises the 1st arm, the 2nd arm and forms the central bend portion that application force produces region, and above-mentioned two clamping zones lay respectively on above-mentioned 1st arm and the 2nd arm.
