  However, in the above-mentioned conventional example, when setting the inside handle device that does not use the lock knob, the boss for connecting the lock knob or the chamber is exposed to the outside only by removing the lock knob. There is a problem that the handle base, which is a main part of the device, needs to be newly set.

  The present invention has been made to solve the above drawbacks, and an object of the present invention is to provide an inside handle device for a vehicle that can share a handle base even if specifications are different.

According to the present invention, the above objects are
An inside handle device for a vehicle, wherein an operation handle 2 is rotatably connected to a tray-shaped handle base 1 fixed to the vehicle,
The handle base 1 is formed with a pair of knob rotation shaft forming portions 3 on opposite side wall portions and a lock knob arrangement region 5 having a knob access opening 4 on a bottom wall portion adjacent to the operation handle 2. With
Provided to the handle base 1 is an inside handle device for a vehicle, in which a cover member 6 that shields the knob access opening 4 and the knob rotation shaft forming portion 3 from an external line of sight is attached to the handle base 1 in a state of being fixed to the vehicle. It is achieved by

  The inside handle device of a vehicle has a handle base 1 which connects an operating handle 2 so as to be rotatable. The handle base 1 is provided with a lock knob placement area 5 adjacent to the operation handle 2. The lock knob arrangement area 5 is provided to secure a space for attaching the lock knob 9 when manufacturing the inside handle device having the specification in which the lock knob 9 is attached. Further, the lock knob 9 is freely rotatable in the lock knob arrangement area 5. A knob rotation shaft forming portion 3 for holding the knob rotation shaft is formed.

  By setting the cover member 6 having a shielding portion that shields the knob rotation shaft forming portion 3 formed on the handle base 1 from the external view, the lock knob 9 is removed from the specifications of the lock knob 9 and the cover member 6 is mounted. The inside handle device without the lock knob 9 can be formed by itself, and by removing the cover member 6 from this state and attaching the lock knob 9 to the knob rotation shaft forming portion 3, the inside handle device having the lock knob 9 specification can be obtained. can do.

  As a result, since the main handle base 1 occupying a large proportion in terms of cost can be shared with different specifications, it is not necessary to separately manufacture a manufacturing die or manage inventory. It becomes possible to reduce the manufacturing cost.

  The cover member 6 has a change in appearance when the lock knob 9 is detached from the lock knob 9 mounting device, that is, the knob rotation shaft forming portion 3 for mounting the lock knob 9 or the end of the knock knob is placed inside the door. The knob access opening 4 for guiding may be mounted only in a region that covers it, or almost the entire bottom wall portion of the handle base 1 including the mounting hole 1e may be formed.

Further, as another aspect of the present invention for achieving the above object,
An inside handle device of a vehicle is provided in which the cover member 6 is provided with a base locking portion 7 that locks with the knob rotation shaft forming portion 3 and restricts movement in a direction away from the handle base 1. You can

  In the present invention, the cover member 6 is mounted on the handle base 1 by locking an appropriate number of base locking parts 7 on the handle base 1, and one of the base locking parts 7 has a lock knob 9 mounted thereon. The lock knob 9 is locked to the knob rotation shaft forming portion 3 that serves as a shaft forming portion for connecting the lock knob 9 to the case.

  The knob rotation shaft forming portion 3 may be a shaft-shaped protruding portion or a hole shape, and in the corresponding base locking portion 7, the knob rotation shaft forming portion 3 is a protruding portion. In this case, it is formed into a hole that can be fitted into this, or is formed into a C-ring shape, and if the knob rotation shaft forming portion 3 is formed into a hole shape, it is formed into a projection shape that can be fitted into this. It

  Further, although the pair of knob rotation shaft forming portions 3 are arranged at opposing positions, the base locking portions 7 may be locked to both of them, or may be locked to only one of them.

  Further, the knob rotation shaft forming portion 3 may use the rotation shaft of the operation handle 2 other than the projection or the recess provided on the wall surface or the like.

  The cover member 6 projects into the knob access opening 4 in place of the knob rotation shaft forming portion 3 and is attached to the handle base 1 in order to restrict the rotation stroke of the lock knob 9 when the lock knob 9 is diverted to a specification in which the lock knob 9 is mounted. It can also be locked to the knob rotation restriction stopper 8 provided.

  As described above, by making the portion required for the lock knob 9 specifications the locking destination of the base locking portion 7, it is not necessary to form a new locking portion, and the structure is simplified.

Further, as another aspect of the present invention for achieving the above object,

  When the cover member 6 covers the knob access opening 4 formed as a through hole, the cover portion may be easily bent when a load is applied to cause a fragile feeling when the cover portion has low rigidity. In the above, since the apparent rigidity of the cover portion in the mounted state can be increased by supporting the central portion in the vertical direction of the portion that closes the knob access opening 4 of the cover member 6, it is not possible to press the cover portion when the cover portion is pressed. It is possible to completely prevent natural bending and the like.

  Further, when the support portion of the cover member 6 is formed in the knob access opening 4 region, it is necessary to consider interference with the mounted lock knob 9 in the lock knob 9 specification, but the knob rotation provided for the lock knob 9 specification is necessary. The structure can be simplified by extending the restriction stopper 8 to the vicinity of the vertical center of the knob access opening 4 region and using the knob rotation restriction stopper 8 as a support portion.

  According to the present invention, the handle base can be shared even if the specifications are different, so that the cost can be reduced.
