  In recent years, it has been desired to further improve the operability in the opening operation of the vehicle door, and in particular, it is desired to reduce the operating force required for the operation of swinging the door handle forward or backward of the vehicle. As a means for solving this problem, the present inventor has considered that the axial position on the door handle pivotally attached to the base of the door handle, that is, the position of the fulcrum is brought close to the pivot position of the link member, that is, the action point. It was done. According to this means, it is possible to reduce the operating force applied to the power point. However, as the distance between the fulcrum and the action point becomes shorter, the rotation distance of the action point becomes shorter, and the conclusion is that the movement stroke of the link member is insufficient to operate the lock release mechanism and the lock release is not performed. Reached.

  The present invention was created in view of the above-described problems, and reduces the door handle operating force while ensuring a sufficient movement stroke of the link member to enable unlocking of the door lock of the vehicle door. An object of the present invention is to provide a vehicle door handle structure.

  In order to achieve the above object, the present invention provides a door handle structure for performing unlocking operation of a door lock in a vehicle door, and the door handle has an operation force for performing opening / closing operation on the door handle. A handle portion to be added, a shaft portion pivotally attached to a base fixed to the vehicle door, and a link member in which one end is linked to a lock release mechanism and the other end of the link member is pivotally attached at a fixed distance from the shaft portion. And a pivot attachment portion, wherein the distance between the handle portion and the shaft portion is variable.

  The door handle preferably includes a pivot body having a shaft portion and a link member pivot portion, and a handle body having a handle portion, and the pivot body and the handle body are slidably engaged with each other. The distance between the handle portion and the shaft portion can be expanded and contracted.

  The handle body and the pivot attachment body are preferably engaged with each other so as to be relatively movable, and a spring damper is disposed between the handle body and the pivot attachment body, so that the handle body and the pivot attachment body are relative to each other. It is energized to the state that was immersive.

  According to the present invention, in the door handle structure for a vehicle, the door handle includes a handle body including a portion that applies an operating force to the door handle, that is, a handle portion serving as a power point, and a rotation center, that is, a fulcrum when the door handle is operated. The shaft portion and the link member are pivotally attached to a pivot attachment portion, that is, a pivot attachment including a force point, and the handle body and the pivot attachment are slidably engaged with each other. Because the distance between the power point and the fulcrum can be expanded and contracted, the distance between the power point and the fulcrum can be increased by extending the handle body from the pivot attachment during the opening operation of the vehicle door. The operating force required for unlocking the door lock at the door handle can be reduced.

  In addition, a spring damper is built in the pivot attachment, and when the handle body is immersed in the pivot joint to reduce the distance between the force point and the fulcrum, the spring damper causes the force point to move away from the fulcrum. When operating force is applied to the handle body and the handle body is urged, the urging force of the spring damper is released and the handle body inserted inside the pivoting body is pushed out, and the distance between the force point and the fulcrum By being configured to extend, the door handle can be extended only when the door handle is operated.
