Therefore, the strength of the coupling portion is reduced. For this reason, for example, when a large force is applied to the connecting portion between the support shaft 103 and the rotor 107r of the damper 107 when the occupant tries to rotate the sun visor body 101 with a strong operating force, the connecting portion may be damaged. .

  The present invention has been made to solve the above problems, and the technical problem of the present invention is that even when a large force is applied to the connecting portion between the support shaft and the rotor of the damper, the connecting portion is damaged. It is to avoid.

The above-described problems are solved by the inventions of the claims.
The invention of claim 1 is attached to a sun visor main body and a ceiling surface of the passenger compartment, and the sun visor main body can be rotated between a storage position along the ceiling surface of the passenger compartment and a use position where light can be shielded. A sun visor for a vehicle comprising a support shaft that supports a rotation center position and a damper that applies a braking force when the sun visor body rotates, wherein the damper is rotatable about a rotor and its axis. And the support shaft includes a large-diameter portion on the proximal end side, a small-diameter portion on the distal end side, and a taper whose diameter is gradually changed between the large-diameter portion and the small-diameter portion. The rotor includes a cylindrical portion into which the small-diameter portion of the support shaft is inserted, and the cylindrical portion protrudes in an axial direction from an end surface of the rotor case. For the sun visor body In relatively non-rotatable state, are held in the sun visor body, the outer peripheral surface of the support shaft is achieved retaining the support shaft from the sun visor body from the proximal end of the small diameter portion to the tapered portion A protrusion is formed so as to protrude radially outward, and the protrusion of the support shaft is fitted from the axial direction to the protruding end of the cylindrical portion of the rotor protruding in the axial direction from the end surface of the rotor case. A rotation stop notch is formed, and the protrusion of the support shaft and the rotation stop notch of the protruding end portion of the cylindrical portion of the rotor are fitted to each other so that the support shaft and the cylindrical portion of the rotor Are held in a relatively non-rotatable manner.

According to the present invention, the rotor of the damper includes a cylindrical portion into which the support shaft is inserted. The cylindrical portion of the rotor is provided with a protruding end portion that protrudes in the axial direction from the end surface of the rotor case. In other words, the rotor of the damper is configured to have a larger diameter than the support shaft, and the support shaft is inserted. For this reason, the intensity | strength of the connection part of the rotor of a damper and a spindle can be made comparatively large. For this reason, even if a passenger | crew tries to rotate a sun visor main body with a strong operation force and a big force is added to the connection part of a spindle and a rotor of a damper, a connection part becomes difficult to be damaged.
Further, since the protrusion for preventing the spindle from coming off from the sun visor body can be used to prevent the spindle and the damper rotor from rotating, the number of parts can be reduced.

Further, between the urging start position M and the use limit position P, the sun visor body 20 receives a holding force that is held at the rotation stop position so that the sun visor body 20 does not rotate due to the rotating force due to its own weight. In the state where the sun visor body 20 is between the bias start position M and the use limit position P, the sun visor body 20 can block sunlight, and this position is the use position of the sun visor body 20.
Further, the sun visor main body 20 is moved to the position of the door window 8 as shown by the two-dot chain line in FIG. Can do.

<About the spindle 30>
The support shaft 30 is composed of a solid shaft body. As shown in FIG. 3, the horizontal axis 32 of the support shaft 30 includes a large-diameter portion 321 on the base end portion side formed in a large diameter and a small-diameter portion on the distal end side formed in a smaller diameter than the large-diameter portion 321. 322. A tapered portion 321t whose diameter is gradually changed is provided at a boundary position between the large diameter portion 321 and the small diameter portion 322 of the horizontal shaft 32. Further, a detent protrusion 323 that is a protrusion protruding radially outward is provided from the tapered portion 321t to the proximal end portion of the small diameter portion 322.
The tip portion of the large-diameter portion 321 of the horizontal shaft 32, that is, the position in the vicinity of the tapered portion 321t is a portion that passes through a bearing portion 25 of the sun visor body 20 described later, and is one place in the circumferential direction of the outer peripheral surface of this portion. Is flattened to form a leaf spring contact flat surface 321b.

<About the sun visor body 20>
The sun visor body 20 is formed in a hollow plate shape by combining a shell-like front shell 21 (see FIG. 1) and a back shell 22 (see FIG. 4 and the like). The front side shell 21 and the back side shell 22 are molded by, for example, injecting resin into a mold. Here, the front side of the sun visor body 20 refers to a surface on the side facing the occupant when the sun visor body 20 is in a use position where light can be shielded.
As shown in FIG. 1, a square recess 21h is formed on the surface of the front shell body 21 of the sun visor body 20 at a position on the right side of the center, and the square mirror unit 20m is fitted into the square recess 21h. It has become.
Further, as shown in FIG. 4, a bearing portion 25 and a damper 26 are provided inside the back side shell 22 of the sun visor body 20 at a position corresponding to the upper right side of the sun visor body 20.

<About the bearing 25>
The bearing portion 25 supports the large-diameter portion 321 of the horizontal shaft 32 of the support shaft 30 and applies a rotational force in the storage position K direction between the storage position K and the bias start position M to the sun visor body 20. A holding force that can be held at the current position can be applied between the force start position M and the use limit position P.
As shown in FIGS. 4 and 5, the bearing portion 25 includes a bearing case 250 formed integrally with the back shell 22 of the sun visor body 20, and a plate spring 24 accommodated in the bearing case 250. . The bearing case 250 is formed in a substantially H-shaped side surface, and a bearing body 253 through which the large-diameter portion 321 of the horizontal shaft 32 of the support shaft 30 passes is formed at the left and right ends of the upper portion of the bearing case 250. A rectangular notch 253k is formed at the lower end position of the bearing body 253. As a result, when the horizontal shaft 32 of the support shaft 30 is passed through the bearing body 253, the anti-rotation protrusion 323 of the horizontal shaft 32 can pass through the rectangular cutout portion 253k.

  The leaf spring 24 of the bearing portion 25 is fitted between the left and right bearing bodies 253 of the bearing case 250. As shown in FIGS. 6 and 7, the leaf spring 24 includes a substantially trapezoidal surrounding portion 241 that presses the outer peripheral surface of the large-diameter portion 321 of the horizontal shaft 32 at two locations at intervals of about 120 ° in the circumferential direction. The U-shaped spring part 244 bent into a hairpin shape continuously to the surrounding part 241 and the other end side of the U-shaped spring part 244 are provided at intervals of about 120 ° with respect to the surrounding part 241 in the circumferential direction. And a flat plate portion 245 that presses the outer peripheral surface of the large-diameter portion 321 of the horizontal shaft 32 from the position where the shaft is placed. The width dimension of the flat plate portion 245 of the plate spring 24 (the width dimension in the direction along the axis of the horizontal shaft 32) is the axial length of the plate spring contact plane 321b formed in the large diameter portion 321 of the horizontal shaft 32. It is set equal to the vertical dimension (see FIG. 5). Further, the width dimension of the surrounding part 241 and the U-shaped spring part 244 of the plate spring 24 is set to a value sufficiently larger than the width dimension of the flat plate part 245.

When the sun visor body 20 is in the use position (between the bias start position M and the use limit position P), as shown in FIG. 7A, the surrounding portion 241 and the flat plate portion 245 of the leaf spring 24 are Both press the outer peripheral surface of the large-diameter portion 321 of the horizontal shaft 32, and the spring force applied to the central direction of the large-diameter portion 321 of the horizontal shaft 32 is balanced in the circumferential direction. For this reason, the large-diameter portion 321 of the horizontal shaft 32 is tightened from the periphery by the spring force of the leaf spring 24, and rotation by the weight of the sun visor body 20 relative to the horizontal shaft 32 of the support shaft 30 is prohibited. That is, the sun visor body 20 is held at the use position.
Further, when the sun visor body 20 is between the retracted position K and the bias start position M, the surrounding portion 241 of the leaf spring 24 is connected to the large diameter portion 321 of the horizontal shaft 32 as shown in FIG. In contrast to pressing the outer peripheral surface, the flat plate portion 245 presses a part of the leaf spring contact flat surface 321b of the large diameter portion 321. Thereby, the balance of the spring force applied to the large-diameter portion 321 of the horizontal shaft 32 is broken in the circumferential direction, and a rotational force in the storage position K direction is applied to the sun visor body 20.

<About damper 26>
The damper 26 applies a braking force to the rotation of the sun visor body 20 in the retracted position K direction so that no unpleasant noise is generated when the sun visor body 20 contacts the ceiling surface 4 of the passenger compartment at the retracted position K. Is for. As shown in FIGS. 4 and 5, the damper 26 includes a cylindrical rotor 270 and a rotor case 260 that supports the rotor 270 so as to be rotatable about its axis.
The rotor case 260 of the damper 26 is formed with a flange portion 261 that is screwed to the back shell 22 of the sun visor body 20 at a lower position.
In addition, a bearing portion (not shown) that supports the rotor 270 so as to be rotatable around the shaft center and a ring-shaped hydraulic chamber (not shown) around the bearing portion are provided at an upper position of the rotor case 260 of the damper 26. Is provided.

As shown in FIG. 5, the rotor 270 includes a cylindrical rotor body 272 through which the small-diameter portion 322 of the horizontal shaft 32 of the support shaft 30 passes. As shown in FIG. 5, the right end portion of the rotor main body 272 protrudes in the axial direction from the rotor case 260, and a detent protrusion 323 formed on the horizontal shaft 32 of the support shaft 30 is fitted into the protruding end portion. A non-rotating cutout 272k is formed. That is, in the rotor 270, the small diameter portion 322 of the horizontal shaft 32 of the support shaft 30 is inserted into the rotor main body 272, and the anti-rotation protrusion 323 of the horizontal shaft 32 is engaged with the non-rotation notch 272 k of the rotor main body 272. Thus, the shaft 30 is held so as not to rotate relative to the horizontal shaft 32 of the support shaft 30.
On the outer peripheral surface of the rotor main body 272 of the rotor 270, a hydraulic pressure receiving portion (not shown) formed in a flange shape is provided coaxially. Then, in a state where the rotor main body 272 of the rotor 270 is accommodated in the bearing portion of the rotor case 260, the hydraulic pressure receiving portion of the rotor 270 is accommodated in the hydraulic chamber of the rotor case 260.
That is, the rotor main body 272 corresponds to the cylindrical portion of the present invention.

<Assembly of sun visor body 20 and spindle 30>
Next, assembly of the sun visor body 20 and the support shaft 30 will be described.
First, as shown in FIGS. 4 and 5, the damper 26 is attached to a predetermined position of the back shell 22 of the sun visor body 20. At this time, as shown in FIG. 8, the phase of the rotation-stop notch 272 k of the rotor 270 of the damper 26 is matched with the phase of the notch 253 k provided in the bearing body 253 of the bearing case 250 of the bearing 25. That is, the rotor 270 of the damper 26 is rotated to hold the rotation-stop notch 272k downward. 8A shows the VIIIA-VIIIA sectional view of FIG. 4, FIG. 8B shows the VIIIB-VIIIB sectional view of FIG. 5, and FIG. 8C shows the VIIIC-VIIIC sectional view of FIG. FIG. 8D shows a sectional view taken along the line VIIID-VIIID of FIG.
In this state, the sun visor body 20 is configured by combining the front side shell 21 and the back side shell 22.
Next, with the anti-rotation protrusion 323 of the horizontal shaft 32 of the support shaft 30 facing downward as shown in FIG. 8, the horizontal shaft 32 is inserted from the right side of the sun visor body 20 to the upper side position of the sun visor body 20. To do. At this time, since the distal end side of the horizontal shaft 32 of the support shaft 30 is a small diameter portion 322, the small diameter portion 322 is smoothly passed through the bearing body 253 and the leaf spring 24 of the bearing portion 25, and the large diameter portion 321 is passed through. It can be led to the position of the bearing body 253 and the leaf spring 24. Here, the rotation prevention protrusion 323 formed between the small-diameter portion 322 and the large-diameter portion 321 of the horizontal shaft 32 is held downward, and the phase of the notch portion 253k formed in the bearing body 253 of the bearing portion 25. It is adapted to. For this reason, the detent protrusion 323 of the horizontal shaft 32 can pass through the notch 253k of the right bearing body 253 (see FIG. 8B), and the large-diameter portion 321 of the horizontal shaft 32 is the bearing portion 25. Can be inserted into.
That is, the large-diameter portion 321 of the horizontal shaft 32 that has passed through the right bearing body 253 is inserted into the leaf spring 24 in the process of being pushed in the left direction, and further the bearing body 253 on the left side (damper 26 side) (FIG. 8C). Inserted). Then, after the non-rotating protrusion 323 of the horizontal shaft 32 passes through the notch 253k of the left bearing body 253, it fits with the notch 272k of the anti-rotation of the damper 26 (rotor body 272) in phase with the notch 253k. (See FIG. 8D). This position is the insertion limit position of the horizontal shaft 32, and the plate spring contact plane 321 b formed in the large-diameter portion 321 of the horizontal shaft 32 has a position in the axial direction of the flat plate provided on the plate spring 24 of the bearing portion 25. It coincides with the position of the portion 245 in the axial direction.

Further, the small diameter portion 322 on the distal end side of the horizontal shaft 32 that has passed through the bearing portion 25 is passed through the rotor main body 272 of the rotor 270 of the damper 26, and then the distal end portion thereof is separated from the rotor main body 272 as shown in FIG. Projects to the left.
In this way, with the horizontal shaft 32 of the support shaft 30 inserted into the sun visor main body 20 to the insertion limit position, the sun visor main body 20 is rotated about the axis with respect to the horizontal shaft 32. As a result, the rotor case 260 of the damper 26 attached to the sun visor body 20 rotates with respect to the rotor 270 of the damper 26 engaged with the horizontal shaft 32 of the support shaft 30. Similarly, the bearing portion 25 attached to the sun visor main body 20 rotates with respect to the horizontal shaft 32 of the support shaft 30. As a result, the anti-rotation protrusion 323 of the horizontal shaft 32 that has passed through the notch 253k of the bearing body 253 on the left side (damper 26 side) of the bearing portion 25 rotates with respect to the notch 253k of the bearing body 253. The main body 253 is hung on the outside. Thereby, the horizontal shaft 32 of the support shaft 30 is prevented from coming off from the sun visor body 20.
For this reason, the damper 26 and the bearing portion 25 of the sun visor body 20 are held so as not to move relative to the horizontal shaft 32 of the support shaft 30 in the axial direction.

<About the operation of the sun visor 10 according to this embodiment>
Next, the operation of the sun visor 10 according to the present embodiment will be described.
When the sun visor 10 is used, the sun visor body 20 at the storage position K is held and rotated to the use position. At this time, until the biasing start position M is exceeded, the rotational torque of the leaf spring 24 that tries to rotate in the storage position K direction with respect to the sun visor main body 20 works, so the sun visor main body 20 is moved with a force exceeding the rotational torque. Rotate.
When the sun visor body 20 exceeds the urging start position M, the spring force of the leaf spring 24 is balanced in the circumferential direction and acts in the direction of tightening the horizontal shaft 32 of the support shaft 30. Accordingly, when the rotation of the sun visor body 20 is stopped at the use position, the sun visor body 20 is held at the current position by the spring force of the leaf spring 24.

  When storing the sun visor 10, the sun visor body 20 in the use position is rotated to the urging start position M against the clamping force (holding force) of the leaf spring 24 and the braking force of the damper 26. And since the rotational torque of the leaf | plate spring 24 which is going to rotate to the storage position K direction with respect to the sun visor main body 20 is added from the urging | biasing start position M, the sun visor main body 20 is set to the storage position K with the rotational torque of the leaf | plate spring 24. Will come back.

<Advantages of the sun visor 10 according to this embodiment>
According to the sun visor 10 according to the present embodiment, the rotor 270 of the damper 26 includes the rotor body 272 tubular portion into which the support shaft 30 (horizontal shaft 32) is inserted. That is, the rotor 270 of the damper 26 is configured to have a larger diameter than the horizontal shaft 32 and the horizontal shaft 32 is inserted. For this reason, the strength of the connecting portion between the rotor 270 of the damper 26 and the horizontal shaft 32 can be made relatively large. For this reason, even if a passenger | crew tries to rotate the sun visor main body 20 with a strong operation force and a big force is added to the connection part of the horizontal shaft 32 and the rotor 270 of the damper 26, a connection part becomes difficult to be damaged.
Further, since the projection 323 for preventing the support shaft 30 (horizontal shaft 32) from coming off from the sun visor body 20 can be used to prevent the rotation of the horizontal shaft 32 and the rotor 270 of the damper 26, the number of parts can be reduced. Become.

<Example of change>
Here, the present invention is not limited to the above-described embodiment, and can be modified without departing from the gist of the present invention. For example, in the present embodiment, as a rotation stop of the horizontal shaft 32 of the support shaft 30 with respect to the rotor 270 of the damper 26, a notch 272k for rotation prevention is formed on the rotor 270, and a rotation stop protrusion 323 is provided on the horizontal shaft 32. The example which fits 272k, 323 is shown.
However, as shown in FIG. 9 (A), a protruding portion 272e is formed on the inner peripheral surface of the rotor body 272 of the rotor 270, and the protruding portion 272e is fitted on the outer peripheral surface of the small diameter portion 322 of the horizontal shaft 32. It is possible to prevent rotation by forming 322f. Further, as shown in FIG. 9B, it is possible to prevent rotation by forming the inner side of the rotor body 272 into a square shape and forming the small diameter portion 322 of the horizontal shaft 32 into a prism shape. Further, as shown in FIG. 9C, a through hole that is continuous in the radial direction is formed from the rotor main body 272 of the rotor 270 to the small diameter portion 322 of the horizontal shaft 32, and a detent pin 272p is inserted into the through hole. But it is possible.
Further, in the present embodiment, an example in which the horizontal shaft 32 of the support shaft 30 is inserted through the rotor 270 of the damper 26 is shown. However, depending on the type of sun visor, as shown in FIGS. 10A and 10B, a configuration in which the tip of the horizontal shaft 32 of the support shaft 30 is held in the rotor 270 of the damper 26 is also possible.
In the present embodiment, as shown in FIGS. 4 and 5, the damper 26 and the bearing portion 25 are fixed to the sun visor body 20, and the damper 26 and the bearing portion 25 are fixed to the horizontal shaft 32 of the support shaft 30. An example in which relative movement is impossible in the axial direction is shown. However, for example, a configuration in which the damper 26 and the bearing portion 25 are slidably held with respect to the sun visor body 20 along the upper side of the sun visor body 20 is also possible.
In the present embodiment, an example in which the damper 26 is screwed to the sun visor main body 20 has been shown. However, the damper 26 can be connected to the bearing portion 25 by screws or welding. Further, for example, it is possible to connect by using another part such as an E-ring.
Moreover, in this embodiment, the example which comprises the spindle 30 from a solid shaft was shown. However, the support shaft 30 can also be configured from a hollow shaft. Further, the horizontal axis 32 can be formed long along the slide rail 23 so that the sun visor body 20 can slide relative to the horizontal axis 32 of the support shaft 30.
