This engagement positions and attaches the case 6 to the support base 41.

(7) Configuration of the board 43 and switch unit 44 of the electrical component 4 The board 43 is supported at three points by support columns 412, 413, and 414 of the support base 41, and is sandwiched between a step portion (not shown) provided on the inner surface of the support base 41 and the support columns 412, 413, and 414, and is disposed within the case 6.
The substrate 43 includes an insulating substrate 431 and a terminal 432. A printed circuit board (PCB) is used as the substrate 43. The insulating substrate 431 is formed in a rectangular plate shape with the vehicle front-rear direction as the longitudinal direction, the vehicle up-down direction as the lateral direction, and the vehicle width direction as the thickness direction. For example, an epoxy resin substrate is used as the insulating substrate 431.
The terminals 432 are disposed on a surface (mounting surface) on the outer side in the vehicle width direction of the insulating substrate 431 and a surface (back surface) on the inner side in the vehicle width direction (not shown). The terminals 432 are formed of, for example, a copper (Cu) thin film. A plurality of terminals 432 are disposed, and the terminals 432 are electrically connected to wiring (not shown) that is arranged on the mounting surface, the back surface, or inside the insulating substrate 431.

A switch unit 44 serving as a switch is mounted on the intermediate portion in the vehicle front-rear direction on the mounting surface of the insulating substrate 431. Here, as the switch unit 44, a push button switch having a plunger on the outer side in the vehicle width direction is used.
An operating part (not shown) erected on the inner wall of the cover body 51 abuts against the plunger of the switch unit 44, and when the operating part moves from the outside in the vehicle width direction to the inside in the vehicle width direction, the operating part presses the plunger, thereby operating the switch unit 44. When the switch unit 44 is operated, a storage system is activated. The storage system stores the handle grip 2 at a storage position Ps inside the door panel 10 shown in Figure 5, and deploys the handle grip 2 at a deployment position Pd outside the door panel 10 shown in Figure 6. Note that the grip body 21 of the handle grip 2 is not shown in Figures 5 and 6.

Here, the storage position Ps is a position where most of the handle grip 2 is stored (housed) within the door panel 10 when the door is not opened or closed and the vehicle is parked, stopped, or traveling. As shown in Fig. 5, in this embodiment, when viewed from the bottom to the top in the vehicle vertical direction, the storage position Ps is set to a position where the outer surface of the grip cover 22 in the vehicle width direction coincides with the outer surface of the door panel 10 in the vehicle width direction (the outer surface of the door outer panel).
On the other hand, the deployed position Pd is a position where the handle grip 2 is deployed (protruded) outside the door panel 10 when the vehicle is parked or stopped, and is a position where the door can be opened or closed. In other words, the position where the operator can securely grip the handle grip and open or close the door is set to the deployed position Pd.

A light emitting source 45 is mounted on the substrate 43. The light emitting source 45 is mounted on a mounting surface on the front side of the insulating substrate 431 in the vehicle longitudinal direction. A light emitting diode (LED) is used as the light emitting source 45. The light emitting source 45 emits light, which passes through the light guide portion 63 of the case 6, and the transmitted light illuminates the area around the grip opening 21G toward the front side in the vehicle longitudinal direction.

One end of the wire harness 9 shown in Fig. 2 is electrically connected to three terminals 432 arranged on the rear side in the vehicle front-rear direction of the board 43 shown in Fig. 3 and arranged side by side in the vehicle up-down direction. The wire harness 9 extends from the electric component 4 toward the inside in the vehicle width direction, and the other end of the wire harness 9 is routed inside the door panel 10. In this embodiment, the wire harness 9 is configured by integrating three wires, ie, a wire 9A, a wire 9B, and a wire 9C.
For example, one end of the wire 9A is electrically connected to the positive terminal of the switch unit 44 via the terminal 432, and the other end is electrically connected to the electronic control device. One end of the wire 9B is electrically connected to the positive terminal of the light source 45 via the terminal 432, and the other end is electrically connected to the electronic control device. One end of the wire 9C is electrically connected to the negative terminal of the switch unit 44 and the negative terminal of the light source 45 via the terminal 432, and the other end is electrically connected to the body earth of the vehicle body.
When the switch unit 44 is turned on, the electronic control device detects the on signal from the switch unit 44 and drives the storage unit to move the handle grip 2 to the storage position Ps or the deployed position Pd.
The light source 45 emits light when power is supplied from a battery that is on/off controlled by an electronic control device.

The sealing portion 42 is formed by assembling the substrate 43 and the support base 41 inside the case 6 as described above, and then dripping and hardening a potting material (e.g., epoxy resin) from the central opening of the support base 41 with the cover 5 positioned downward. The sealing portion 42 is filled into the central opening of the support base 41 without any gaps, preventing water and other substances from entering the case 6 from the opening side of the support base 41.

(8) Configuration of the Harness Hanging Part 415 As shown in Figures 2 to 4, the harness hanging part 415 is disposed on the electric component 4 inside the handle grip 2, and the harness hanging part 415 is disposed on the inner side of the electric component 4 in the vehicle width direction. The harness hanging part 415 includes an extension part 415A and a wrapping body 415B as main components. Furthermore, the harness hanging part 415 is configured to include a bent part 415C and a locking part 415D.

3 and 4, the extension portion 415A of the harness hanging portion 415 is formed integrally or one-piece with the side wall on the front side in the vehicle front-rear direction of the frame body 411 of the support base 41. The extension portion 415A extends from the inner end of the frame body 411 in the vehicle width direction toward the inside in the vehicle width direction, and is formed in a rectangular column shape with the extension direction being the central axis of the column. The extension portion 415A may be formed in a cylindrical shape, an elliptical column shape, a triangular column shape, a pentagonal or higher polygonal column shape.
The wrapping body 415B extends from the rear end surface of the extension portion 415A in the vehicle front-rear direction rearward in the vehicle front-rear direction at the vehicle width direction intermediate portion of the extension portion 415A. This extending direction coincides with the central axis CC direction of the wrapping around which the wire harness 9 is wrapped. The wrapping central axis CC direction coincides with the longitudinal direction of the handle grip 2 and is the same direction as the vehicle front-rear direction. The wrapping body 415B is formed in a substantially cylindrical or substantially prismatic shape with the wrapping central axis CC direction being the central axis direction of the pillar.
2, one end of the wire harness 9 is wound around the wrapping body 415B. Here, the wire harness 9 is wound around the wrapping body 415B by one turn. The number of turns is set to two or less, preferably one, in order to allow the wire harness 9 to move freely in the length direction around the wrapping body 415B.

The bent portion 415C is a rear end portion of the wrapping body 415B in the vehicle front-rear direction, and is configured by bending the end portion of the wrapping body 415B in the direction of the central axis C-C of the wrapping outward in the vehicle width direction. This bending direction coincides with the deployment direction of the handle grip 2 from the storage position Ps (see FIG. 5) to the deployment position Pd (see FIG. 6).
When viewed from the bottom to the top of the vehicle in the vertical direction, the shape formed by including the hanging body 415B and the bent portion 415C is a 90-degree hook shape. Furthermore, the shape formed by including the extension portion 415A, the hanging body 415B, and the bent portion 415C is a 180-degree hook shape.

The locking portion 415D is configured by protruding the outer end of the bent portion 415C in the vehicle width direction downward in the vehicle up-down direction. This protruding direction is a direction intersecting the central axis C-C direction of the wrapping and the deployment direction of the handle grip 2, specifically, a direction perpendicular to each of them.
When viewed from the rear side in the vehicle longitudinal direction to the front side in the vehicle longitudinal direction, the shape formed by including the bent portion 415C and the engaging portion 415D is a 90-degree hook shape.

The extension portion 415A, the wrapping body 415B, the bent portion 415C, and the locking portion 415D of the harness hook portion 415 are integrally or integrally configured. Furthermore, in this embodiment, each component of the harness hook portion 415 is integrally or integrally configured with the support base 41.

(Part of the storage system)
The storage system of the door handle device 1 is constructed to include a moving arm 7, as shown in Figures 1, 2, 5 and 6. The moving arm 7 has an arm body 71, which has a front end portion 72, a rear end portion 73 and an intermediate portion 74.

The arm body 71 has its longitudinal direction roughly in the fore-and-aft direction of the vehicle, its short direction roughly in the width direction of the vehicle, and its thickness direction in the vertical direction of the vehicle, and is formed in a V-shape with the outer side in the vehicle width direction open when viewed from the lower side in the vertical direction of the vehicle to the upper side in the vertical direction of the vehicle.
The front end portion 72 is a portion of the arm body 71 on the front end side in the vehicle longitudinal direction, and is the other end of the moving arm 7, and is disposed within the handle grip 2. The front end portion 72 is rotatably connected to the rear pole portion 21B of the grip body 21. More specifically, the front end portion 72 is provided with a rotating shaft 75A whose axial direction is the vehicle vertical direction, and this rotating shaft 75A is fitted into a connecting hole 21E disposed in the rear pole portion 21B of the grip body 21. The front end portion 72 is rotatable about the rotating shaft 75A. As a result, the other end of the moving arm 7 is disposed on the vehicle rear side of the electric component 4 and the harness hanging portion 415.
On the other hand, the rear end portion 73 is a portion of the arm body 71 on the rear end side in the vehicle front-rear direction, is one end of the moving arm 7, and is disposed inside the door panel 10 (inside the door). The rear end portion 73 is rotatably connected inside the door panel 10. To explain in more detail, a rotation shaft 75B having an axial direction in the vertical direction of the vehicle is disposed in the rear end portion 73, and this rotation shaft 75B is fitted into a connecting hole (not shown) disposed in the door panel 10. The rear end portion 73 is rotatable around the rotation shaft 75B.

That is, as shown in Fig. 5, when the other end of the moving arm 7 rotates counterclockwise around the rotation shaft 75B, the handle grip 2 moves to the stored position Ps and is stored. Also, as shown in Fig. 6, when the other end of the moving arm 7 rotates clockwise around the rotation shaft 75B, the handle grip 2 moves to the deployed position Pd and is deployed.
The moving arm 7 is connected to an actuator (not shown) that constitutes a storage system, and is moved by driving the actuator based on a control signal from an electronic control unit (ECU) (not shown). In the door handle device 1 of this embodiment, the moving arm 7 disposed on the rear end side of the handle grip 2 in the vehicle longitudinal direction has been described, but a similar moving arm is also disposed on the front end side of the handle grip 2 in the vehicle longitudinal direction.

The intermediate portion 74 is a portion between the front end portion 72 and the rear end portion 73 of the arm body 71, and is disposed inside the electric component 4 and the harness hanging portion 415 in the vehicle width direction and on the rear side of the vehicle (on one longitudinal side of the handle grip 2). When the handle grip 2 is stored in the storage position Ps, the intermediate portion 74 is located inside the door panel 10 and disposed along the vehicle front-rear direction. When the handle grip 2 is deployed from the storage position Ps to the deployment position Pd, the intermediate portion 74 rotates clockwise around the rotation axis 75A and moves closer to the electric component 4 and the harness hanging portion 415.

2, a harness holding part 8 is attached to the intermediate portion 74. When the handle grip 2 is deployed from the storage position Ps to the deployment position Pd, the harness holding part 8 is configured to displace toward the front of the vehicle and approach the electric components 4 and the harness hanging part 415. The harness holding part 8 is configured to include a holding body 81, a holding part 82, and an engagement part 83.
The retaining body 81 is arranged along the upper surface of the intermediate portion 74 in the vertical direction of the vehicle, the inner side of the intermediate portion 74 in the vehicle width direction, and the lower surface of the intermediate portion 74 in the vertical direction of the vehicle, and is formed into a C-shape with the outer side in the vehicle width direction open when viewed from the front of the vehicle in the fore-and-aft direction.
The holding portion 82 holds a longitudinal middle portion of the wire harness 9 between itself and a side surface of the middle portion 74 on the inner side in the vehicle width direction via a protective tube 91. For example, a heat shrink tube is used as the protective tube 91. As a result, a portion between one end and the middle portion of the wire harness 9 extends from the harness hanging portion 415 toward the inner side and rear side in the vehicle width direction.
The engaging portions 83 are formed to penetrate the upper and lower surfaces of the holding body 81 in the vertical direction of the vehicle, and are engaged with engaged portions 76 formed at corresponding positions of the intermediate portion 74. This engagement allows the harness holding portion 8 to be attached to the moving arm 7 in a state in which the harness holding portion 8 holds an intermediate portion of a wire harness 9 whose one end is electrically connected to the electric component 4 and whose other end is routed inside the door panel 10.

(Action and Effect)
As shown in FIGS. 1 to 6, the door handle device 1 according to this embodiment includes a handle grip 2, a moving arm 7, a harness holding portion 8, electric components 4, and a wire harness 9.
The handle grip 2 is movable between a storage position Ps where the handle grip 2 is stored in the door panel 10 as shown in Fig. 5 and a deployment position Pd where the handle grip 2 is deployed outside the door panel 10 as shown in Fig. 6. The moving arm 7 has one end rotatably connected to the inside of the door panel 10 and the other end rotatably connected to the inside of the handle grip 2. The moving arm 7 moves the handle grip 2 between the storage position Ps and the deployment position Pd. The harness holding portion 8 is attached to the moving arm 7. The electric component 4 is disposed in the handle grip 2 and has a switch unit 44 (see Fig. 3) that stores or deploys the handle grip 2. The wire harness 9 has one end electrically connected to the electric component 4, a middle portion of which is held by the moving arm 7 via the harness holding portion 8, and the other end of which is routed in the door panel 10.

Figures 5, 7(A) and 7(B) show the handle grip 2 stored in the storage position Ps inside the door panel 10. At this time, the wire harness 9 is arranged so that no overload is generated in the portion from one end connected to the electrical component 4 of the wire harness 9 to the intermediate portion held by the harness holding portion 8.

Here, as shown in Figs. 2 to 4, the door handle device 1 has a harness hanging portion 415, and one end of the wire harness 9 is hung on the harness hanging portion 415. Specifically, one end of the wire harness 9 is wrapped around the harness hanging portion 415. The harness holding portion 8 is disposed on the vehicle rear side of the harness hanging portion 415 and holds the longitudinal middle portion of the wire harness 9. When the handle grip 2 moves from the stored position to the deployed position, the harness holding portion 8 is displaced toward the vehicle front side and approaches the harness hanging portion 415. Therefore, as shown in Fig. 6, when the handle grip 2 moves from the stored position to the deployed position, the portion of the wire harness 9 between the harness hanging portion 415 and the harness holding portion 8 in the wire harness 9 is bent, so that excessive bending of the wire harness 9 can be suppressed. Therefore, the overload of the wire harness 9 can be reduced.

Moreover, the harness hanging portion 415 has a wrapping body 415B extending in the vehicle front-rear direction, and one end of the wire harness 9 is wrapped around the wrapping body 415B. That is, the wire harness 9 is wrapped around the central axis C-C direction along the longitudinal direction of the handle grip 2. For this reason, as shown in Figures 6 and 8A, when the handle grip 2 moves from the stored position Ps to the deployed position Pd, the portion of the wire harness 9 from the harness hanging portion 415 to the intermediate portion can be deformed into a large arc shape toward the front side in the vehicle front-rear direction along the central axis C-C direction of the wrapping of the harness hanging portion 415.
Furthermore, in the event of an overload, as shown in FIG. 8B, the portion of the wire harness 9 that is wound around the harness hanging portion 415 can be deformed into a large arc shape that expands radially outward around the winding central axis CC.
Therefore, it is possible to effectively reduce the overload on the wire harness 9 that occurs when the handle grip 2 moves to each of the stored position Ps and the deployed position Pd.

If the wire harness 9 were to be repeatedly subjected to an overload, it could bend, causing damage to the insulating coating of the wires 9A to 9C, or even cause a break in the wires. The door handle device 1 according to this embodiment can solve this fundamental problem.

3 and 4, in the door handle device 1 according to this embodiment, the harness hanging portion 415 is formed in a hook shape having a wrapping body 415B and a bent portion 415C. The wrapping body 415B extends along the wrapping central axis C-C. The bent portion 415C is formed by bending the end of the wrapping body 415B in the wrapping central axis C-C direction toward the unfolding direction of the handle grip 2.
For this reason, when the handle grip 2 is deployed from the stored position Ps to the deployed position Pd (see FIGS. 5 and 6), the bent portion 415C is present in the wrapping body 415B along the moving direction of the moving arm 7 and the moving direction of the wire harness 9. In other words, even if the portion of the wire harness 9 wrapped around the harness hanging portion 415 moves or spreads radially outward around the central axis C-C of the wrapping, it is restrained by the bent portion 415C and can be prevented from coming off the wrapping from the harness hanging portion 415.

3 and 4, in the door handle device 1 according to the present embodiment, the harness hanging portion 415 further includes a locking portion 415D. The locking portion 415D is formed by protruding an end of the bent portion 415C of the harness hanging portion 415 in a direction intersecting with the central axis C-C of the winding and the deployment direction. To explain in detail, the locking portion 415D is formed by protruding an outer end of the bent portion 415C in the vehicle width direction downward in the vehicle up-down direction in a direction perpendicular to both the vehicle front-rear direction and the vehicle width direction.
For this reason, when the handle grip 2 is deployed from the stored position Ps to the deployed position Pd (see FIGS. 5 and 6), the locking portion 415D is present at the bent portion 415C in a direction different from the moving direction of the moving arm 7 and the moving direction of the wire harness 9. In other words, even if the portion of the wire harness 9 that is wound around the harness hanging portion 415 moves or spreads radially outward around the central axis C-C of the winding, it is held down by the locking portion 415D that is unrelated to the moving direction, and the winding can be prevented from coming off from the harness hanging portion 415.
7B, the wire harness 9 extending from the electric component 4 located outside the harness hanging portion 415 in the vehicle width direction is wound around the wrapping body 415B from the lower side in the vehicle vertical direction in a counterclockwise direction, and the wire harness 9 that has made one turn is stacked on the rear side in the vehicle front-rear direction, i.e., on the side of the bent portion 415C, and is wound around the wrapping body 415B so as to extend from the lower side in the vehicle vertical direction toward the harness holding portion 8. In contrast, by configuring the locking portion 415D to protrude downward in the vehicle vertical direction from the end of the bent portion 415C, it is possible to more effectively suppress or prevent the harness from coming off the wrapping from the harness hanging portion 415.

Furthermore, in the door handle device 1 of this embodiment, as shown in Figures 3 and 4, the electrical component 4 has a support base 41 on which the switch unit 44 is mounted, and the harness hanging portion 415 is formed integrally or integrally with the support base 41.
Therefore, the harness hanging portion 415 can be provided by utilizing the support base 41 of the electric component 4, and the structure of the electric component 4 including the harness hanging portion 415 can be simplified. In addition, the harness hanging portion 415 does not need to be provided as a separate component, and the number of components of the electric component 4 can be reduced. Furthermore, compared to a case in which the harness hanging portion 415 is provided on the case 6, for example, the harness hanging portion 415 does not get in the way when the board 43 is attached to the case 6, and assembling can be improved.
In the manufacturing method (assembly method) of the door handle device 1, the electrical components 4 can be assembled into the handle grip 2 in a state in which the wire harness 9 is wound around the harness hanging portion 415 (see FIG. 2). This improves the ease of assembly of the electrical components 4 and the wire harness 9 into the handle grip 2.

Second Embodiment
A door handle device 100 according to the second embodiment will be described with reference to Figures 9 to 12. The door handle device 100 of the second embodiment is configured similarly to the door handle 1 of the first embodiment, except for the following points. In Figures 9 to 12, the same reference numerals are used for parts configured similarly to the first embodiment. Also, in Figures 9 and 10, the grip body 21 of the handle grip 2 is not shown.

That is, in the second embodiment, the switch knob 3 is omitted in the door handle device 100. In addition, in the second embodiment, instead of the electric component 4, an electric component 110 is provided in the handle grip 2. The electric component 110 is configured as a touch sensor, and is configured to detect the touch of the occupant to the handle grip 2 by the electric component 110. An end holding portion 112 is provided at the vehicle width direction inner end of the housing 111 that constitutes the outer shell of the electric component 110, and a holding hole 112A that penetrates in the front-rear direction is formed in the end holding portion 112. Then, one end of the wire harness 9 extending from the vehicle width direction inner end of the electric component 110 is held by the end holding portion 112, and one end side portion of the wire harness 9 extends outward in the vehicle width direction from the end holding portion 112. Specifically, one end of the wire harness 9 is inserted into the holding hole 112A from the rear side of the vehicle, wound around the end holding portion 112, and folded back outward in the vehicle width direction. In the second embodiment, the wire harness 9 is composed of two wires, 9A and 9B.

In the second embodiment, the harness hook 415 is provided on the outer side of the electric component 110 in the vehicle width direction and protrudes from the electric component 110 toward the rear of the vehicle. The harness hook 415 is disposed near the rotating shaft 75A and on the vehicle front side of the rotating shaft 75A. That is, the harness hook 415 is disposed on the outer side of one end of the wire harness 9 in the vehicle width direction and on the vehicle front side of the moving arm 7. In the second embodiment, the extension portion 415A and the locking portion 415D are omitted in the harness hook 415, and the harness hook 415 is composed of the wrapping body 415B and the bent portion 415C. Specifically, the wrapping body 415B protrudes from the electric component 110 toward the rear of the vehicle, and the bent portion 415C is bent toward the outer side in the vehicle width direction at the tip of the wrapping body 415B.

Then, one end portion of the wire harness 9 extending from the end holding portion 112 to the outside in the vehicle width direction is hung on the harness hanging portion 415 and folded back to the inside in the vehicle width direction. Furthermore, the wire harness 9 folded back to the inside in the vehicle width direction by the harness hanging portion 415 is held at its middle portion by the harness holding portion 8. Also, the grip cover 22 of the handle grip 2 is disposed close to the outside in the vehicle width direction of the bent portion 415C of the harness hanging portion 415. More specifically, the distance between the bent portion 415C in the vehicle width direction and the handle grip 2 is set to be smaller than the outer diameter of the wiring 9A and wiring 9B. This results in a configuration in which the handle grip 2 prevents the wire harness 9 from coming loose from the harness hanging portion 415.

In the second embodiment, when the handle grip 2 moves from the stored position to the deployed position, the harness holding portion 8 is displaced toward the front of the vehicle and approaches one end of the wire harness 9. Therefore, when the handle grip 2 moves from the stored position to the deployed position, the portion of the wire harness 9 between the harness hanging portion 415 and the harness holding portion 8 bends, preventing the wire harness 9 from being excessively bent. Therefore, overload on the wire harness 9 can be reduced.

Moreover, in the second embodiment, one end of the wire harness 9 is held by the end holding portion 112, and the wire harness 9 extends from the end holding portion 112 toward the inside in the vehicle width direction. In addition, one end portion of the wire harness 9 extending from the end holding portion 112 is hung on the harness hanging portion 415 and folded back toward the inside in the vehicle width direction. Therefore, when the harness holding portion 8 (i.e., the middle portion of the wire harness 9) approaches one end of the wire harness 9 when the handle grip 2 moves from the stored position to the deployed position, the one end portion of the wire harness 9 is bent and deformed into a loop shape when viewed from the front-rear direction of the vehicle (see FIG. 12). Therefore, the overload of the wire harness 9 can be effectively reduced.

In addition, in the second embodiment, the grip cover 22 of the handle grip 2 is disposed close to the outer side of the bent portion 415C of the harness hanging portion 415 in the vehicle width direction, and the handle grip 2 prevents the wire harness 9 from coming off the harness hanging portion 415. Therefore, even if the wire harness 9 is simply hung on the harness hanging portion 415, the wiring state of the wire harness 9 within the handle grip 2 can be maintained in a good condition.

In addition, in the second embodiment, one end portion of the wire harness 9 extending from the end holding portion 112 is hung on the harness hanging portion 415 and folded back toward the inside in the vehicle width direction. Therefore, it is no longer necessary to wrap the wire harness 9 around the harness hanging portion 415 as in the first embodiment. This improves the workability when routing the wire harness 9.

In addition, in the second embodiment, the harness hanging portion 415 is disposed near the rotation axis 75A, so that the amount of deflection of the wire harness 9 can be reduced, and the overload of the wire harness 9 can be effectively reduced.

[Other embodiments]
The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit and scope of the present invention.
For example, in the harness hanging portion of the first embodiment, the shape of the end portion of the wrapping body on the outer side in the vehicle width direction may be formed into an arc shape concave inward in the vehicle width direction when viewed from the lower side to the upper side in the vehicle vertical direction.

Furthermore, in the harness hanging portion of the first embodiment, the protruding direction of the engaging portion may be set to the upper side in the vehicle vertical direction.
In the first embodiment, the wire harness 9 is wound around the winding body 415B in a counterclockwise direction as viewed from the rear side in the vehicle longitudinal direction, but may be wound around the winding body 415B in a clockwise direction as viewed from the rear side in the vehicle longitudinal direction. In that case, when the wire harness 9 is wound around the winding body 415B and made one turn, and the wire harness 9 is stacked on the bent portion 415C side as in the first embodiment and extends from the upper side of the winding body 415B in the vehicle vertical direction toward the harness holding portion 8, the locking portion 415D may be configured to protrude from the end of the bent portion 415C in the vehicle vertical direction upward, so that the wire harness 9 can be more effectively prevented from coming off the harness hanging portion 415.
In addition, in the present invention, the electrical components may be lighting devices, antenna devices, and other electrical components that have a wire harness that needs to be stored inside the handle grip 2, and the functions and uses of the electrical components are not limited.
