ABSTRACT:
A screw grommet 1 which is capable of dealing with a change in the thickness of panel comprises a grommet member 3 and a holding member 2 to hold the grommet member. The holding member comprises a flange formed larger than a mounting hole of a panel 33 and a leg portion 4 which extends downward from the flange, is formed with, in its center, a space to receive the grommet member, and passes through the mounting hole of the panel so as to extend to the bottom side of the panel. The grommet member 3 comprises a head 17 which is fixed so as to be prevented from vertical movements when received in the leg portion of the holding member, a tubular portion 19 which is received vertically movably in the leg portion of the holding member and is formed with a hole for a tapping screw 5 to be screwed thereinto, and a pair of connection arms 20 which connect the tubular portion to the head and bend so as to project radially outwardly in mid portions 25 thereof when the tubular portion is brought closer to the head. When the tapping screw 5 is screwed in, the mid portions 25 of the connection arms 20 project outwardly to sandwich the panel 33 and an ornamental member 34 associatedly with the flange 6 to connect them together.
