PURPOSE: To firmly secure a handle, to improve exchange serviceability, and to improve grip feeling by a method wherein a handle part mounted on a door body is divided into two sections and formed with inner and outer handle members, and the handle part is mounted on the door body by means of screws.

CONSTITUTION: A pair of fixing members 5 are temporarily locked to the back of a door body 1 by means of positioning protrusions 6 and 6 and positioning holes 4 and 4 on the door body 1 side and a handle base 8 are then engaged with a notch part 2. Small protrusions 20 and 20 formed on two mounting base parts 18 and 18 of a handle member 14 are engaged with engaging recesses 13 and 13 on the mounting pieces 9 and 9 side of the handle base 8 to mount the fixing members to a handle base 8. Finally, screws 21 and 21 are screwed in threaded holes 7 and 7 of the fixing members 5 and 5 through screw mounting holes 19 and 19 of the inner handle member 14, screw insertion holes 10 and 10 of the handle base 8, and mounting holes 3 and 3 of the door body 1. Thereafter, by injecting foamed urethane in the door body 1 to fill the door body therewith, the fixing members 5 and 5 are completely fixed by means of foamed urethane. Finally, an outer handle member 22 is engaged with the inner handle member 14 to complete a handle member.
