Abstract

PROBLEM TO BE SOLVED: To provide at a low cost a masking material used to prevent a painting mist from being adhered to the edges of suspension member mounting holes provided at the fender apron of an automobile.SOLUTION: The masking material includes a square box body section 21 that is inserted between a fender 4 and the fender apron 6 and covers the suspension member mounting holes at the fender apron 6, finger insertion sections 22, 23 formed at upper/lower portions of the square box body section 21, and a box sub-body 24 that is extended from the internal side of the square box body section 21 and is inserted into a suspension member accommodation section provided inside the fender apron 6, and is formed by bending one sheet.

Description

  The present invention relates to a masking material used for preventing paint from adhering to the periphery of a suspension member mounting hole such as a link provided in a fender apron.

As shown in FIGS. 1 and 2, a fender 4 that covers the wheel 3 of the automobile 1 and forms the outer surface of the vehicle body 2 is disposed, and the wheel 3 is housed in a wheel house 5 inside the fender 4, A fender apron 6 is disposed on the inner side of the fender apron 6 and a suspension member accommodating portion 7 for accommodating a member such as a suspension link is set inside the fender apron 6. The fender apron 6 is provided with a suspension member mounting hole 8 for inserting a fastener such as a bolt for fixing the suspension member.
On the other hand, a protective paint such as polyvinyl chloride sol is applied to the bottom of the automobile 1 along the side sill 9 to prevent scratches caused by collisions (chipping) of pebbles and sand that are thrown up while the automobile is running. ing.
When spraying the protective paint, if a mist of paint adheres to the periphery of the suspension member mounting hole 8 of the fender apron 6, a fastener such as a bolt inserted and tightened through the mounting hole 8 and the periphery of the mounting hole 8 There arises a problem that a gap is generated or the fastening of the fastener is loosened.
Therefore, conventionally, adhesion of paint is prevented by sticking an adhesive tape or the like to the attachment hole and a portion where it is desired to prevent paint mist from adhering to the periphery.
