Therefore, the grip portion 30 is smoothly rotated around the core rod 50.
[0030]
Therefore, when the handle 2 of the door handle 1 is grasped and the door 2 is opened, as shown in FIG. 5, with the conventional door handle, if the handle is not slid in the palm of the hand, In this door handle 1, the grip portion 3 is rotatable, so that the hand is in the position indicated by the solid line without sliding the grip portion in the palm of the hand.
[0031]
[Embodiment 3]
As shown in FIGS. 6 and 7, the door handle 11 according to the third embodiment has support members 49 and 59 that are rotatably provided on the door surface fixing legs 4 and 5, respectively. It is inserted into the open end.
[0032]
As shown in FIGS. 6 and 7, the grip portion 33 is formed in a cylindrical shape with a hard synthetic resin, and is slightly smaller than the center hole 33b by the width of a support main body 49a described later from each end portion. A large enlarged diameter hole 33a is provided.
[0033]
As shown in FIGS. 7 and 8, the door surface fixing leg 4 includes a first member 47 that mainly forms an inner wall 47a and both end walls 47b and 47c, and a second member 48 that mainly forms an outer wall 48a. And a support member 49 attached to the one end wall 47c of the first member 47 so as to be rotatable and prevented from coming off. In the assembled state shown in FIG. It is formed in a shape. The door surface fixing legs 4 are made of an elastic synthetic resin.
[0034]
As shown in FIGS. 7 and 8, the first member 47 has a reinforcing rib 47h on the inner wall 47a, an insertion hole 47g for attaching the assembly hole 47f and the support member 49 to the one end wall 47c, and the other end. The wall 47b is provided with an assembly hole 47d and a screw insertion hole 47e for attaching to the door.
