Japanese Unexamined Patent Publication No. 2005-264525

In the outside handle as described above, the handle case has a pair of side walls that limit the rotation range of the handle body by coming into contact with the handle body. Therefore, depending on the shape of the pair of side walls, stress may be concentrated on a part of the side walls when the user strongly operates the handle body. An object of the present invention is to provide a vehicle door handle device capable of suppressing stress concentration on a side wall of a case that limits the amount of rotation of the door handle.

Hereinafter, means for solving the above problems and their actions and effects will be described.
The vehicle door handle device for solving the above problems includes a case configured to be attached to the vehicle door and a door handle rotatably supported by the case, and the door handle is attached to the case. The case has a rotating portion that is rotatably supported, a handle that extends from the rotating portion to the outside of the vehicle door, and a lever that extends from the rotating portion to the inside of the vehicle door. Has a penetrating portion in which a through hole into which the lever is inserted is formed, and the penetrating portion has a pair of side walls that define a rotation range of the door handle by contacting the lever, and the pair of side walls. It is configured to include a pair of connecting walls connecting the pair of side walls so that the through holes are formed between the side walls, and the pair of side walls separate from each other toward the tip from the base end thereof. The rotating portion extends in a direction and has a cylindrical outer peripheral surface centered on the rotation axis of the door handle, and the lever has a pair of contact planes in contact with each of the pair of side walls. The pair of contact planes extend from the outer peripheral surface in the tangential direction of the outer peripheral surface so as to sandwich the rotating portion, and extend in a direction approaching each other from the base end of the lever toward the tip end .

In a vehicle door handle device, when a lever comes into contact with one side wall due to rotation of the door handle, a load acts on the one side wall. In this respect, the vehicle door handle device having the above configuration distributes the load acting on one side wall to a pair of connecting walls connected to one side wall, or distributes the load acting on one side wall to the pair of connecting walls, or the other connected via the pair of connecting walls. It can be dispersed on the side wall. Therefore, the vehicle door handle device can suppress stress concentration on the side wall of the case.

For example, when a pair of side walls assume a case of modification extending parallel in the extending direction of the pair of side walls, the distance between the pair of side walls is constant. Therefore, in the case of the modified example, in order to secure the rotation range of the lever, it is necessary to increase the distance between the pair of side walls or reduce the wall thickness of the pair of side walls. In this respect, in the case of the above configuration, since the pair of side walls extends in the direction away from the proximal end toward the distal end, it is possible to suppress the problem in the case of the above modified example.

According to the above configuration, the length in the width direction of the lever orthogonal to the longitudinal direction of the lever gradually decreases from the base end of the lever, that is, from the rotating portion toward the tip of the lever. In other words, the lever has no portion in the longitudinal direction where the length in the width direction is extremely small. Therefore, when the reaction force from the side wall of the case acts on the lever, stress concentration is unlikely to occur locally. Therefore, the vehicle door handle device can improve the durability of the lever.

The vehicle door handle device for solving the above problems includes a case configured to be attached to the vehicle door and a door handle rotatably supported by the case, and the door handle is attached to the case. The case has a rotating portion that is rotatably supported, a handle that extends from the rotating portion to the outside of the vehicle door, and a lever that extends from the rotating portion to the inside of the vehicle door. Has a penetrating portion in which a through hole into which the lever is inserted is formed, and the penetrating portion has a pair of side walls that define a rotation range of the door handle by contacting the lever, and the pair of side walls. A pair of connecting walls connecting the pair of side walls so that the through holes are formed between the side walls is included in the lever so as to cover the inner opening of the through holes. The front end surface of the pair of connecting walls provided with a shielding member is an arc surface centered on the rotation axis of the door handle, and the distance from the rotation axis to the arc surface is the rotation axis. It has shorter than the distance to the shield member from.
In a vehicle door handle device, when a lever comes into contact with one side wall due to rotation of the door handle, a load acts on the one side wall. In this respect, the vehicle door handle device having the above configuration distributes the load acting on one side wall to a pair of connecting walls connected to one side wall, or distributes the load acting on one side wall to the pair of connecting walls, or the other connected via the pair of connecting walls. It can be dispersed on the side wall. Therefore, the vehicle door handle device can suppress stress concentration on the side wall of the case.

In order to relieve the stress generated on the side wall due to the contact with the lever, it is conceivable to extend the pair of connecting walls inward to increase the rigidity of the penetrating portion. However, if the pair of connecting walls is extended inward, the pair of connecting walls may interfere with the shielding member that rotates together with the door handle (lever). In this respect, according to the above configuration, the rigidity of the penetrating portion can be increased by extending the pair of connecting walls inward while avoiding interference between the pair of connecting walls and the shielding member.

The vehicle door handle device for solving the above problems includes a case configured to be attached to the vehicle door and a door handle rotatably supported by the case, and the door handle is attached to the case. The case has a rotating portion that is rotatably supported, a handle that extends from the rotating portion to the outside of the vehicle door, and a lever that extends from the rotating portion to the inside of the vehicle door. Has a penetrating portion in which a through hole into which the lever is inserted is formed, and the penetrating portion has a pair of side walls that define a rotation range of the door handle by contacting the lever, and the pair of side walls. It is configured to include a pair of connecting walls connecting the pair of side walls so that the through holes are formed between the side walls, and each of the pair of side walls has a regulating surface in contact with the lever. It has the regulating surface, rather than the proximal end of said pair of side walls Ru is formed at a position closer to the tip.
In a vehicle door handle device, when a lever comes into contact with one side wall due to rotation of the door handle, a load acts on the one side wall. In this respect, the vehicle door handle device having the above configuration distributes the load acting on one side wall to a pair of connecting walls connected to one side wall, or distributes the load acting on one side wall to the pair of connecting walls, or the other connected via the pair of connecting walls. It can be dispersed on the side wall. Therefore, the vehicle door handle device can suppress stress concentration on the side wall of the case.

According to the above configuration, the size of the regulated surface can be easily controlled in that the area of the regulated surface is smaller than that in the case where the regulated surface is formed from the base end to the tip of the pair of side walls. As a result, the vehicle door handle device can easily define the end position of the rotation range of the door handle.

The vehicle door handle device for solving the above problems includes a case configured to be attached to the vehicle door and a door handle rotatably supported by the case, and the door handle is attached to the case. The case has a rotating portion that is rotatably supported, a handle that extends from the rotating portion to the outside of the vehicle door, and a lever that extends from the rotating portion to the inside of the vehicle door. Has a penetrating portion in which a through hole into which the lever is inserted is formed, and the penetrating portion has a pair of side walls that define a rotation range of the door handle by contacting the lever, and the pair of side walls. It is configured to include a pair of connecting walls connecting the pair of side walls so that the through holes are formed between the side walls, and the distance between the pair of connecting walls is the rotation axis of the door handle. towards the middle than at both ends in the circumferential direction of not narrow.
In a vehicle door handle device, when a lever comes into contact with one side wall due to rotation of the door handle, a load acts on the one side wall. In this respect, the vehicle door handle device having the above configuration distributes the load acting on one side wall to a pair of connecting walls connected to one side wall, or distributes the load acting on one side wall to the pair of connecting walls, or the other connected via the pair of connecting walls. It can be dispersed on the side wall. Therefore, the vehicle door handle device can suppress stress concentration on the side wall of the case.
According to the above configuration, the vehicle is passed through the through hole in that the distance between the central portions of the pair of connecting walls is narrower than that when the distance between the pair of connecting walls is constant in the circumferential direction of the rotation axis. It becomes difficult for running wind and foreign matter to enter from the outside to the inside of the door. Further, as compared with the case where the distance between the pair of connecting walls is constant in the circumferential direction of the rotation axis, the distance between both ends of the pair of connecting walls is widened, so that the pair of side walls and the pair of connecting walls intersect. It becomes easy to provide a large R shape in the corner. That is, the vehicle door handle device can increase the degree of freedom in the design and manufacture of the case.
The vehicle door handle device includes a shielding member provided on the lever so as to cover the inner opening of the through hole.

According to the vehicle door handle device having the above configuration, stress concentration on the side wall of the case that limits the amount of rotation of the door handle can be suppressed.

Further, the slide door 10 includes a transmission member 13 that mechanically connects the lock device 11 and the remote control device 12, and an outer panel 14 that constitutes the outer surface of the slide door 10.

The lock device 11 has a fully closed lock 111 that restrains the slide door 10 in the fully closed position, and a fully open lock 112 that restrains the slide door 10 in the fully open position. The fully closed lock 111 is provided at the front and rear of the slide door 10, and the fully open lock 112 is provided at the front of the slide door 10. The transmission member 13 is composed of, for example, a wire cable, a rod, a link, and the like. Further, the lock device 11 releases the restraint of the slide door 10 based on the operation of the door handle device 20 of the user. In this way, the user can open and close the slide door 10.

As shown in FIGS. 2A and 2B, the outer panel 14 is formed with a recess 141 recessed inward of the slide door 10. A mounting hole 142 for mounting the door handle device 20 is formed through the recess 141 at the center thereof. The mounting hole 142 has a substantially oval shape with the vertical direction of the vehicle as the longitudinal direction and the front-rear direction of the vehicle as the lateral direction. Further, in the following description, the inside of the slide door 10 is also referred to as "inside X1", and the outside of the slide door 10 is also referred to as "outside X2". The inner X1 is a direction from the outer panel 14 toward the inside of the slide door 10, and the outer X2 is a direction from the outer panel 14 toward the outside of the slide door 10. In this embodiment, the inner X1 and the outer X2 are also in the width direction of the vehicle.

Next, the door handle device 20 will be described in detail. The door handle device 20 of the present embodiment is an outside door handle provided on the outside of the slide door 10.
As shown in FIGS. 2A and 2B, the door handle device 20 has a door handle 30 gripped by the user, a case 40 that rotatably supports the door handle 30, and a door handle 30 in a neutral position. A spring 21 (see FIG. 7) for urging the door handle device 20 and a shielding member 22 for closing the opening formed in the door handle device 20 are provided. Further, the door handle device 20 includes a connecting member 23 for connecting the transmission member 13 and the door handle 30, and a sealing member 24 provided between the case 40 and the outer panel 14. In the door handle device 20, at least the door handle 30 and the case 40 are formed by resin molding. Therefore, it is preferable that the door handle 30 and the case 40 are appropriately provided with lightening and stealing so as not to cause molding defects such as sink marks and warps.

In the following description, in the front view of the door handle device 20, the direction in which the rotation axis of the door handle 30 extends is also referred to as the "height direction" of the door handle device 20, and the direction orthogonal to the height direction is referred to as the door handle device 20. Also called "width direction". The width direction is also a direction orthogonal to both the inner X1 and outer X2 directions.

As shown in FIGS. 3 (a) and 3 (b) and FIGS. 4 (a) and 4 (b), the door handle 30 is rotatably supported by the case 40 from the rotating portion 31 and the rotating portion 31. It has a handle 32 extending outward X2 and a lever 33 extending inward X1 from the rotating portion 31. The door handle 30 has a substantially axisymmetric shape in a plan view at a height.

The rotating portion 31 has a substantially cylindrical shape with the extending direction of the rotating axis RX as the height direction, and has a circumferential surface 311 centered on the rotating axis RX. An insertion hole 312 centered on the rotation axis RX is formed through the rotating portion 31 in the height direction.

The handle 32 has a hollow columnar shape whose height is the direction in which the rotation axis RX extends. The handle 32 has a height equivalent to that of the rotating portion 31. The handle 32 has a grip portion 321 gripped by the user and a surface 322 constituting the design surface of the door handle device 20.

The lever 33 has a flat plate shape with the height direction as the thickness direction, and extends inward X1 from the central portion in the height direction of the rotating portion 31. The lever 33 has a pair of contact planes 331 that come into contact with the case 40 when the door handle 30 rotates, and a holding portion 332 that holds the shielding member 22. A connecting hole 333 for fixing the connecting member 23 is formed through the tip of the lever 33 in the direction in which the rotation axis RX extends. Further, as shown in FIG. 4A, the lever 33 tapers from the proximal end toward the distal end in a plan view in the height direction. Therefore, the pair of contact planes 331 extend from the circumferential surface 311 of the rotating portion 31 in the tangential direction of the circumferential surface 311 so as to sandwich the rotating portion 31, and move from the base end to the tip of the lever 33. It extends to get closer to each other.

As shown in FIGS. 5A and 5B and FIGS. 6A to 6D, the case 40 protects the base 41 attached to the outer panel 14 and the handle 32 of the door handle 30 from the height direction. A portion 42, an accommodating portion 43 accommodating a part of the door handle 30, and a penetrating portion 50 in which a through hole 60 into which the lever 33 of the door handle 30 is inserted are formed. Further, as shown in FIG. 7, the case 40 includes a support shaft 44 that supports the door handle 30.

As shown in FIGS. 5A and 5B, the base 41 has a thin plate shape curved along the recess 141 of the outer panel 14, and has a shape slightly larger than the mounting hole 142 of the recess 141 of the outer panel 14. ing. In the central portion of the base 41, an accommodating hole 411 that exposes the accommodating portion 43 to the outside X2 is formed. The protective portions 42 are provided on the outside of the base 41 so as to form a pair on both sides of the base 41 in the height direction. The protection unit 42, together with the door handle 30, constitutes the design surface of the door handle device 20.

As shown in FIGS. 5A and 5B, the accommodating portion 43 has a semi-cylindrical first wall portion 431 having an axial direction in the height direction and one end in the axial direction of the first wall portion 431. It has a second wall portion 432 that covers the second wall portion 432 and a third wall portion 433 that covers the other end of the second wall portion 432 in the axial direction. A penetrating portion 50 is integrally formed at the central portion of the first wall portion 431 in the height direction. A support hole 434 for supporting the support shaft 44 is formed through the second wall portion 432 and the third wall portion 433 in the height direction.

As shown in FIGS. 6A to 6C, the penetration portion 50 includes a pair of side walls 51, 52 (first side wall 51 and second side wall 52) and a pair of connecting walls extending from the first wall portion 431. 53, 54 (first connecting wall 53 and second connecting wall 54) are provided. The pair of side walls 51 and 52 have a substantially rectangular plate shape. As shown in FIG. 6 (c), the pair of side walls 51 and 52 are separated from each other toward the tip from the base end connected to the first wall portion 431 so as to face each other in the circumferential direction of the rotation axis RX. It extends in the direction. The pair of side walls 51 and 52 have a regulating surface 55 that defines the rotation range of the door handle 30 by coming into contact with the lever 33 of the door handle 30 that rotates about the rotation axis RX. The regulation surfaces 55 of the pair of side walls 51 and 52 are formed so as to face each other in the circumferential direction of the rotation axis RX. As shown in FIG. 6D, the regulation surface 55 of the pair of side walls 51 and 52 is formed at a position closer to the tip than the base end of the pair of side walls 51 and 52.

Further, as shown in FIGS. 6 (c) and 6 (d), the second side wall 52 has a flat surface 521 chamfered substantially parallel to the extending direction of the first side wall 51. As shown in FIG. 6C, when the penetration portion 50 is viewed from the extending direction of the rotation axis RX, the distance D1 between the pair of side walls 51 and 52 in the direction orthogonal to the plane 521 is the pair of side walls in the width direction. It is shorter than the interval D2 of 51 and 52.

As shown in FIG. 6 (c), the pair of connecting walls 53 and 54 form an annular fan-shaped plate and extend inward X1 from the first wall portion 431 so as to face each other in the height direction. Therefore, the tip surfaces of the pair of connecting walls 53 and 54 are arc surfaces 56 centered on the rotation axis RX. Here, as shown in FIGS. 4A and 6C, the distance L2 from the rotation axis RX to the arc surface 56 of the case 40 is from the rotation axis RX to the holding portion 332 of the door handle 30. It is shorter than the distance L1.

As shown in FIG. 6A, the pair of connecting walls 53, 54 has a protruding portion 57 protruding toward the other connecting wall facing the other connecting wall at the central portion in the circumferential direction of the rotation axis RX. Therefore, in the height direction of the pair of connecting walls 53 and 54, the distance D3 at the center portion in the circumferential direction of the rotation axis RX is shorter than the distance D4 at both ends.

As shown in FIGS. 6A to 6C, the pair of connecting walls 53, 54 has a width of the pair of side walls 51, 52 so that a through hole 60 is formed between the pair of side walls 51, 52. Connect both ends in the direction. As a result, the penetration portion 50 is formed with a through hole 60 surrounded by a pair of side walls 51, 52 and a pair of connecting walls 53, 54. As shown in FIG. 6A, corners R are provided at the four corners 58 where the pair of side walls 51 and 52 and the pair of connecting walls 53 and 54 intersect.

Then, as shown in FIG. 7, with the door handle 30 and the spring 21 housed in the case 40, the door handle 44 is passed through the support hole 434 of the accommodating portion 43 and the insertion hole 312 of the door handle 30. 30 is rotatably supported in the first rotation direction R1 and the second rotation direction R2 with respect to the case 40. When the door handle 30 rotates from the neutral position to the first rotation direction R1, the spring 21 applies a force corresponding to the amount of rotation to the second rotation direction R2 of the door handle 30, and the door handle 30 causes the door handle 30 to rotate. When rotating in the second rotation direction R2 from the neutral position, a force corresponding to the rotation amount is applied to the first rotation direction R1 of the door handle 30. Here, the neutral position of the door handle 30 is the position of the door handle 30 shown in FIG. 7, where the surface 322 of the handle 32 of the door handle 30 is flush with the surface of the protective portion 42 of the case 40. be.

Further, as shown in FIGS. 8A and 8B, when the door handle 30 and the spring 21 are assembled to the case 40, the lever 33 of the door handle 30 protrudes from the through hole 60 of the case 40. A shielding member 22 is attached to the holding portion 332 of the lever 33 protruding from the case 40. The shielding member 22 has a plate shape curved around the rotation axis RX and covers the opening of the inner X1 of the through hole 60. Further, the connecting member 23 connected to the transmission member 13 is connected to the connecting hole 333 of the lever 33 protruding from the case 40.

The door handle device 20 thus assembled is attached to the mounting hole 142 of the recess 141 of the slide door 10. Specifically, the penetration portion 50 of the case 40 of the door handle device 20 is inserted into the mounting hole 142 of the recess 141. Here, as shown in FIG. 6C, the door handle device 20 of the present embodiment is a pair in a direction orthogonal to the plane 521 by chamfering the second side wall 52 of the penetration portion 50 of the case 40. The distance D1 between the side walls 51 and 52 is shorter than the distance D2 between the pair of side walls 51 and 52 in the width direction. Therefore, even if the distance in the width direction of the mounting holes 142 of the recess 141 is less than the distance D2 in the width direction of the penetration portion 50 of the case 40, the door handle device 20 can be slightly tilted around the rotation axis RX. The situation where the penetration portion 50 of the case 40 of the door handle device 20 cannot be inserted into the mounting hole 142 is avoided.

Hereinafter, the operation and effect of this embodiment will be described.
(1) When the user operates the door handle 30 in the first rotation direction R1 and the second rotation direction R2, the lever 33 of the door handle 30 pulls the transmission member 13, and the user's operating force is fully closed. It is transmitted to the lock 111 and the fully open lock 112. As a result, when the slide door 10 is located in the fully closed position, the slide door 10 can move in the opening direction from the fully closed position, and when the slide door 10 is located in the fully open position, the slide door 10 is fully opened. It becomes possible to move in the closed direction from the position. Further, when the user finishes the operation on the door handle 30, the door handle 30 returns to the neutral position due to the elastic force of the spring 21 deformed by the rotation of the door handle 30.

Here, when the user operates the door handle 30, the lever 33 of the door handle 30 comes into contact with one side wall of the case 40. For example, as shown in FIG. 8B, when the lever 33 (contact surface 331) comes into contact with the first side wall 51 (regulatory surface 55) due to the rotation of the door handle 30 in the second rotation direction R2, A load acts on the first side wall 51. In this respect, the door handle device 20 of the present embodiment distributes the load acting on the first side wall 51 to the pair of connecting walls 53 and 54 connected to the first side wall 51, or distributes the load acting on the pair of connecting walls 53. , 54 can be dispersed in the second side wall 52 connected via 54. Therefore, the door handle device 20 can suppress stress concentration on the side wall (first side wall 51) of the case 40 that limits the amount of rotation of the door handle 30.

(2) Unlike the present embodiment, assuming a modified door handle device including a case in which a pair of side walls extend in parallel, the distance between the pair of side walls is constant in the direction in which the pair of side walls extend. Therefore, as in the case 40A of the door handle device 20A according to the modification shown in FIG. 9A, it is necessary to increase the distance between the pair of side walls 51A and 52A in order to secure the rotation range of the lever 33. Occurs. Further, as in the case 40B of the door handle device 20B according to the modified example shown in FIG. 9B, the thickness of the tips of the pair of side walls 51B and 52B is thinned in order to secure the rotation range of the lever 33. It will be necessary to do it. In this respect, in the case 40 of the present embodiment, the pair of side walls 51 and 52 extend in a direction away from the base end toward the tip end. Therefore, the door handle device 20 secures the rotation range of the lever 33 and increases the distance between the pair of side walls 51A and 51B in the width direction as in the case 40A shown in FIG. 9A. Deterioration of the insertability of the recess 141 of the slide door 10 into the mounting hole 142 is suppressed. Further, the door handle device 20 can prevent the strength of the tip portions of the pair of side walls 51B and 52B from being lowered as in the case 40B shown in FIG. 9B.

(3) In the door handle device 20, the length in the width direction of the lever 33 orthogonal to the longitudinal direction of the lever 33 gradually decreases from the base end of the lever 33, that is, from the rotating portion 31 toward the tip of the lever 33. .. In other words, the lever 33 does not have a portion where the length in the width direction is locally reduced in the longitudinal direction. Therefore, when the reaction force from the side wall of the case 40 acts on the lever 33, stress concentration is unlikely to occur locally. Therefore, the door handle device 20 can improve the durability of the lever 33.

(4) In order to relieve the stress generated on the side walls 51 and 52 of the case 40, it is conceivable to extend the pair of connecting walls 53 and 54 inward X1 to increase the rigidity of the penetrating portion 50. However, when the pair of connecting walls 53, 54 is extended inward X1, the pair of connecting walls 53, 54 may interfere with the shielding member 22 that rotates together with the door handle 30 (lever 33). In this respect, in the present embodiment, the distance L2 from the rotation axis RX to the arc surface 56 is less than the distance from the rotation axis RX to the shielding member 22, that is, the distance L1 from the rotation axis RX to the holding portion 332. It has become. As a result, as shown in FIG. 8B, a gap is formed between the connecting wall 53 (connecting wall 54) and the shielding member 22. Therefore, the rigidity of the penetrating portion 50 can be increased by extending the pair of connecting walls 53 and 54 inward X1 while avoiding interference between the pair of connecting walls 53 and 54 and the shielding member 22.

(5) In the door handle device 20, the regulation surface 55 of the pair of side walls 51 and 52 is formed at a position closer to the tip than the base end of the side walls 51 and 52. Therefore, as compared with the case where the regulation surface 55 is formed from the base end to the tip of the pair of side walls 51 and 52, the area of the regulation surface 55 becomes smaller, which makes it easier to control the dimensions of the regulation surface 55. .. As a result, the door handle device 20 can easily define the end position of the rotation range of the door handle 30.

(6) In the pair of connecting walls 53 and 54, the distance D3 at the center is narrower than the distance D4 at both ends in the circumferential direction of the rotation axis RX. Therefore, as compared with the case where the distance between the pair of connecting walls 53 and 54 is constant in the circumferential direction of the rotation axis RX, the distance between the central portions of the pair of connecting walls 53 and 54 becomes narrower, and the through hole is formed. Traveling wind and foreign matter are less likely to enter from the outside to the inside of the vehicle door via the 60.

Further, as compared with the case where the distance between the pair of connecting walls 53 and 54 is constant in the circumferential direction of the rotation axis RX, the distance between both ends of the pair of connecting walls 53 and 54 becomes wider, so that the pair of side walls It becomes easy to provide a large R shape (corner R) at the corner 58 where the 51, 52 and the pair of connecting walls 53, 54 intersect. That is, the door handle device 20 can increase the degree of freedom in designing and manufacturing the penetration portion 50 of the case 40, and can increase the strength of the penetration portion 50. Further, even if a relatively large R shape is provided at the corner portion 58 where the pair of side walls 51, 52 and the pair of connecting walls 53, 54 intersect, the regulation surface 55 that comes into surface contact with the pair of contact planes 331 of the lever 33 is provided. It can be taken relatively long in the height direction.

This embodiment can be modified and implemented as follows. The present embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.
The door handle device 20 may be a modified example shown in FIGS. 9A and 9B. Specifically, as shown in FIG. 9A, the door handle device 20 may be a door handle device 20A provided with a connecting wall 53A connecting a pair of side walls 51A and 52A, or as shown in FIG. 9B. The door handle device 20B may be provided with a connecting wall 53B connecting the pair of side walls 51B and 52B. The effect (1) of the above embodiment can also be obtained in the door handle devices 20A and 20B according to the modified example. Although only one connecting wall 53A and 53B is shown in FIGS. 9A and 9B, the door handle devices 20A and 20B are provided with a pair of connecting walls.

The shapes of the case 40 and the door handle 30 of the door handle device 20 in the above embodiment are examples, and the shapes may be changed as appropriate.
The door handle device 20 does not have to have the shielding member 22. In this case, it is preferable that the pair of connecting walls 53 and 54 extend inward X1 within a range that does not come into contact with the constituent members of the slide door 10 such as the inner panel. In other words, the tip surface of the pair of connecting walls 53, 54 does not have to be an arc surface 56 centered on the rotation axis RX.

The door handle device 20 may be provided inside the vehicle of the sliding door 10 as an inside door handle, or may be provided on the front door and the back door. In this case, the door handle device 20 may be attached to the door so that the rotation axis RX of the door handle 30 is tilted with respect to the height direction of the vehicle.
