Japanese Utility Model Publication No. 62-12758

  However, in the above-described conventional example, since the key insertion opening is disposed on the bottom wall of the handle receiving recess, the operation space of the unlocking key is set around the unlocking key with the unlocking key inserted into the key insertion opening. It is necessary to secure it. For this reason, when setting the depth and width dimensions of the handle housing recess, consideration for the operation space is required, and there is a drawback that the degree of freedom in designing the outer surface is reduced.

  The present invention has been made to solve the above-described drawbacks, and an object of the present invention is to provide an automobile door having an increased degree of freedom in designing the outer surface. Another object of the present invention is to provide a handle device that can be used for this door.

  The automobile door includes an operation handle 4 that provides a handle when the door is opened and closed, and a cylinder lock 7 that operates locking and unlocking of the door. The handle portion 3 of the operation handle 4 is used when the door of the automobile is not in use. It is accommodated in a handle accommodating recess 2 formed on the outer surface.

  On the other hand, the cylinder lock 7 is fixed to the bottom wall of the handle housing recess 2, and the unlocking operation is performed by rotating the unlocking key 6 inserted from the key insertion opening 5 of the cylinder lock 7. The locking / unlocking operation angle of the cylinder lock 7 is set to be less than 90 ° in the clockwise and counterclockwise directions centered on the neutral rotation position. The handle receiving recess 2 has a length of the key insertion opening 5 in the neutral rotation position. The side is fixed in a posture that faces the longitudinal direction of the operation handle 4.

  Therefore, in this invention, the unlocking key 6 is inserted into the cylinder lock 7 in such a posture that the width direction of the blade portion inserted into the cylinder lock 7 coincides with the longitudinal direction of the handle portion 3 of the handle. The locking stroke is unlocked by reciprocating the rotation stroke. In general, the operation head 6a for rotating the unlocking key 6 is formed in a cross-sectional shape that is long in the width direction of the blade portion from the center of rotation so as to easily apply rotational torque during operation. In the posture, the longitudinal direction of the operation head 6 a of the unlocking key 6 coincides with the longitudinal direction of the handle portion 3, that is, the longitudinal direction of the handle housing recess 2. As a result, even when the operation head 6a is inserted into the handle housing recess 2 while being inserted into the cylinder lock 7, the handle housing recess 2 can accommodate the operation head 6a. Interference between the portion 6a and the anti-dose housing recess wall surface can be prevented.

  Further, as shown in FIG. 10, when the operation angle of the cylinder lock 7 is θ and the distance from the rotation center of the operation head 6a is L, the cylinder lock 7 can be locked and unlocked without causing interference with the handle housing portion. In order to rotate it to such a rotational position, the width dimension of the handle housing recess 2 needs to be at least 2Lsinθ. In the present invention in which the operation angle is set to be less than 90 °, the width dimension of the handle housing recess 2 is 2L, that is, smaller than the arm length of the operation head 6a. 3 can be formed narrowly, and the degree of freedom in design increases.

  Further, in a so-called reversible key that allows the front and back to be reversed without regard to the insertion position of the unlocking key 6 into the cylinder lock 7, the cross-sectional center of the blade and the rotation center of the plug 11 are often shifted. However, even in this case, it is not necessary to increase the width dimension of the handle accommodating recess 2, that is, the handle portion 3 of the handle.

  According to the present invention, in order to absorb the operation space of the unlocking key in the longitudinal direction region of the handle housing recess, the handle housing recess, that is, the handle portion 3 of the operation handle 4 can be formed with a narrow width. Can increase the degree of design freedom.

  As shown in FIG. 1, a door for an automobile is formed by joining an inner panel 1a and an exterior panel 1b in a bag shape, and fixing a door trim (not shown) to the inner panel 1a as necessary. 1 and is horizontally rotated around a hinge 1c formed in front of the vehicle body (left side in FIG. 1) to open and close the opening of the vehicle body.

  The door panel structure 1 is provided with a latch device 12 that is locked to the vehicle body side and maintains a closed state, and a locking portion 14 that performs locking and unlocking operations under the control of the locking and unlocking control portion 13 mounted on the vehicle body. . The door opening operation from the closed state is based on the condition that the latch device 12 is unlocked, and the locking portion 14 allows the latch device 12 to shift to the unlocked state only in the unlocked state.

  Further, by fixing a handle device A, which will be described later, to the door panel structure 1, an escutcheon 10 in which the frame portion 9 is exposed on the surface of the exterior panel 1 b and a handle fitting opening 9 a formed in the frame portion 9 of the escutcheon 10. The operation handle 4 with the handle portion 3 exposed is disposed in the frame portion 9 so as to fit into the frame portion 9. The operation handle 4 is rotated so that the handle portion 3 is pulled out from the frame portion 9 during the door opening operation, and the latch device 12 is shifted to the unlocked state. In order to meet the design requirements, when the door is not opened, the handle portion 3, the frame portion 9, and the exterior panel 1b are arranged on substantially the same plane.

  Further, as shown in FIG. 1B, the operation handle 4 is disposed so that the door rotates about the hinge 1c at the front of the vehicle body as a rotation center, while being rotated about the rear of the vehicle body as the rotation center.

  The escutcheon 10 is equipped with a locking / unlocking operation switch 15 connected to the locking / unlocking control unit 13 via a harness 15a. When the locking / unlocking operation switch 15 is pressed, the locking / unlocking control unit 13 outputs a request signal as a wireless output, and prompts the user to output an authentication ID signal from a portable ID transmitter (not shown) possessed by the user. On the condition that authentication for the authentication ID output from the portable ID transmitter is established, the locking / unlocking control unit 13 operates the locking unit 14 to shift to either locking / unlocking state.

  Details of the handle device A are shown in FIG. As shown in FIG. 7, the handle device A includes a handle device body 16 in which the operation handle 4 is rotatably connected to the handle base 8, and an escutcheon 10 connected to the handle device body 16.
