  However, in the above-mentioned conventional example, the pull handle is formed in a bottomed cylindrical shape in which the side surface and the bottom surface are integrated, and since the rigidity is large, the vehicle causes a side collision, and the armrest of the door interior material becomes an occupant. When it hits, there exists a problem that there exists a possibility that the input from an armrest to a passenger | crew may become large.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an armrest structure for a vehicle door that can alleviate input to an occupant when a side collision occurs.

In order to achieve the above object, according to the present invention, an opening is formed on the upper surface of an armrest that protrudes from the door interior material toward the vehicle interior side, and a pull handle that opens upward is accommodated in the opening. In the armrest structure of a vehicle door, the pull handle forms a side surface on the vehicle interior side, and has a handle main body having an opening formed at the bottom , and the handle main body so as to seal the opening of the handle main body. The bottom surface of the handle is detachably locked to the bottom surface of the handle. When a load greater than a predetermined value is input to the handle body toward the outside of the vehicle compartment, the handle body deforms and the bottom surface of the handle body is It is characterized in that it is configured to move downward.

  In the present invention, first, when the vehicle causes a side collision and the armrest portion hits the occupant, a reaction force acts on the armrest portion from the occupant at the same time. The reaction force from the occupant deforms the handle body, and the handle bottom surface moves away from the handle body. Thus, since the rigidity and strength of the entire pull handle at the time of a vehicle collision can be reduced, the input to the occupant can be greatly eased.
