In addition, by using the fixing structure and the structure of the enlarged opening, the through-hole portion of the door to be attached is configured with relatively thin bolts, which eliminates the need for screw hole processing and large-diameter fixing hole processing and makes it relatively easy. Door processing can be performed. In particular, in the door handle structure set, complicated torsional moments are generated from both sides, so that the mounting stability can be achieved by using elastic resin legs.

  In addition, it is preferable that the sum total of the contact area to the attachment target of the plurality of leg portions 2 is at least 50% or more of the projected area of the handle body 1 to the attachment target.

  By taking the above measures, it is excellent in texture and appearance without impairing the integrity of the appearance of the handle, and it is excellent in design with both securing the attachment strength to the door and downsizing the leg itself Could provide a door handle.
