It is configured to be pressed against the hole wall surface.
Therefore, the force conversion part and the first locking part have a simple configuration.

According to the invention described in claim 3, the force conversion portion can be disposed in a non-contact state in the hole of the first locking portion, and the force conversion portion and the first locking portion are Both are non-circular. And the force conversion part rotates with respect to the 1st latching | locking part, and it has the structure which a part of force conversion part press-contacts to a part of hole edge of a 1st latching | locking part.
Therefore, since the force conversion portion and the first locking portion are both non-circular, the force conversion portion can be pressed against the first locking portion with an easy configuration.
Further, the force conversion part may be disposed in a non-contact state in the hole of the first locking part. Therefore, it is easy to install the force conversion part in the hole of the first locking part. Thus, it is easy to attach the fastener to the ceiling panel.

According to the fourth aspect of the present invention, the restraining means for positioning the bearing member so as not to rotate with respect to the main body member is provided between the main body member and the bearing member. And the press contact state with respect to the 1st latching | locking part of a force conversion part and the press contact state with respect to the 2nd latching | locking part of an engaging part are comprised by the restraining means.
Therefore, the fastener is stably attached to the ceiling panel by the restraining means.
By the way, the structure for converting the rotational torque into the sliding force is provided between the force converting portion provided in the bearing member and the first locking portion formed in the ceiling panel (see claim 1). On the other hand, the restraining means according to the present invention is provided between the bearing member and the main body member. Therefore, the structure for converting the rotational torque into the sliding force and the restraining means can be provided without being affected by each other. Thus, the construction of the fastener is facilitated.

  According to the present invention, the structure of the support for attaching a spindle of a vehicle sun visor is simplified.

An embodiment of the present invention will be described with reference to FIGS.
As shown in FIG. 1, the vehicle sun visor 13 includes a plate-like visor body 13 a that forms a light shielding portion, a support shaft 14 that rotatably supports the visor body 13 a, and a support shaft 14 that is attached to the ceiling panel 10. And a fastener 1 to be used.

The vertical axis 14b is attached to the ceiling panel 10 via the fastener 1 so as to be rotatable in the direction around the axis. Therefore, by rotating the support shaft 14 around the vertical axis 14b, the visor body 13a rotates to the front position along the front glass surface 11 and the side position along the side glass surface 12.

As shown in FIG. 2, the fastener 1 includes a main body member 3 and a bearing member 2.
The main body member 3 is provided with a fitting insertion hole 3a at a substantially central position, and has an engaging portion 31 at a part of the outer peripheral edge.
The insertion hole 3a penetrates the main body member 3 in a circular shape in the thickness direction, and a part of the bearing member 2 is rotatably inserted.
The engaging portion 31 is configured to protrude from the upper surface of the main body member 3 toward the ceiling panel 10, and is configured to be inserted into the second locking portion 10 b of the ceiling panel 10.

As shown in FIG. 2, the bearing member 2 includes a main body cylinder portion 20, a flange portion 21, a neck portion (force conversion portion) 22, a head portion 23, and a cylinder head portion 24. An insertion hole 2 a is formed at the shaft center of the bearing member 2.
The insertion hole 2a is configured to penetrate the bearing member 2 in the vertical direction, and the vertical axis 14b is penetrated from below. The vertical axis 14b is supported by the bearing member 2 so as to be rotatable about the axis.
The main body cylinder portion 20 is formed in a cylindrical shape. And the main-body cylinder part 20 is rotatably supported by the main-body member 3 by being inserted by the insertion hole 3a.
The flange portion 21 is provided on the outer peripheral surface of the main body cylinder portion 20 and is disposed on the upper surface side of the main body member 3. And when the fastener 1 is installed in the ceiling panel 10, the flange part 21 is installed in the through-hole 15a of the lining material 15 affixed on the lower surface of the ceiling panel 10. FIG.

The neck portion 22 is provided between the flange portion 21 and the head portion 23. The neck portion 22 is disposed at the same height as the first locking portion 10 a of the ceiling panel 10 when the fastener 1 is installed on the ceiling panel 10. That is, the neck portion 22 is disposed in the first locking portion 10a.
The neck portion 22 has a non-circular configuration as shown in FIG. And it has press surface 22a, 22c and press-contact surface 22b, 22d, 22e.
The pressing surfaces 22a and 22c are positioned farther from the center position than other portions, that is, have a swollen configuration. Further, the pressure contact surfaces 22b and 22d have a smaller curvature than other portions and are substantially flat. The pressure contact surface 22e has a substantially arc shape in cross section.

As shown in FIG. 8, the first locking portion 10a in which the neck portion 22 is provided has a non-circular shape, for example, a substantially polygonal shape (such as a triangle), and penetrates the ceiling panel 10 (hole shape). Is configured). And the neck part 22 is inserted in the 1st latching | locking part 10a, and is arrange | positioned in the non-contact state in the hole of the 1st latching | locking part 10a. And the neck part 22 forms the clearance gap 16 between the 1st latching | locking parts 10a in the state inserted by the 1st latching | locking part 10a.
The neck portion 22 rotates with respect to the ceiling panel 10 together with the support shaft 14 by rotating the support shaft 14 in the arrow X direction as described below. And the neck part 22 rotates in the 1st latching | locking part 10a. Thereby, the pressing surface 22a of the neck part 22 is pressed by the hole wall surface 10a1 of the 1st latching | locking part 10a. Then, the pressing surface 22c is pressed against the hole wall surface 10a2.

Each of the hole wall surfaces 10a1 and 10a2 is directed obliquely in the arrow Y direction (in the direction of the second locking portion 10b of the ceiling panel 10) and also in the direction facing each other. Accordingly, the neck 22 is pressed against the hole wall surfaces 10a1 and 10a2 and is pressed in the direction of the arrow Y by receiving pressure from the hole wall surfaces 10a1 and 10a2. Thus, the neck portion 22 receives a sliding force in the arrow Y direction.
In other words, the neck portion 22 is a non-circular cam body. And the cam action arises between the neck 22 and the 1st latching | locking part 10a because the neck 22 rotates with respect to the 1st latching | locking part 10a. The neck portion 22 receives a sliding force in the direction of arrow Y by the cam action.

In a state where the neck portion 22 has finished rotating with respect to the first locking portion 10a, the press contact surfaces 22b, 22d, 22e are pressed against the hole wall surfaces 10a1, 10a2, 10a3 as shown in FIG.
As shown in FIG. 2, the head 23 is configured in a non-circular column shape, for example, a triangular column shape, and is configured to be slightly smaller than the first locking portion 10 a of the ceiling panel 10. The head portion 23 has three retaining portions 23a at the corners as shown in FIG.

Between the main body member 3 and the bearing member 2, as shown in FIG. 2, the restraining means (20a, 32) which positions the bearing member 2 so that rotation is impossible is provided.
The restraining means includes a movable restraining portion 20 a provided on the bearing member 2 and a fixed restraining portion 32 provided on the main body member 3.
As shown in FIG. 2, the movable restraining portion 20 a has a configuration in which a part of the outer surface of the main body cylinder portion 20 is recessed.
The fixed restraint part 32 has the extension part 32a and the nail | claw part 32b. The extending portion 32a extends in a cantilever shape from a part of the hole edge of the fitting insertion hole 3a, and is configured to be easily elastically deformed. The nail | claw part 32b protrudes toward the insertion insertion hole 3a from the extension part 32a, and becomes a structure which can be inserted in the movable restraint part 20a.

Between the bearing member 2 and the support shaft 14, torque transmission means (14e, 25) are provided as shown in FIG. The torque transmission means includes a torque applying portion 14 e provided on the support shaft 14 and a torque receiving portion 25 provided on the bearing member 2.
The torque applying portion 14e protrudes from the outer peripheral surface of the vertical axis 14b toward the inner peripheral surface of the main body cylinder portion 20 (see FIG. 2), and the torque receiving portion 25 is supported from the inner surface of the main body cylinder portion 20 of the bearing member 2. It protrudes toward the shaft 14 (see FIG. 3). Therefore, the torque application part 14e pushes the torque receiving part 25 by rotating the support shaft 14 around the vertical axis 14b. For this reason, the rotational torque is transmitted to the bearing member 2 through the torque transmitting means.

The support shaft 14 has a flange 14d and a groove 14c as shown in FIG.
The flange 14d is configured to swell radially on the outer peripheral surface of the vertical axis 14b. The flange 14d is disposed on the lower surface of the main body member 3 to cover and close the lower opening of the fitting insertion hole 3a.
As shown in FIG. 2, the groove 14c is formed near the tip of the vertical axis 14b.

Next, a method for attaching the spindle 14 to the ceiling panel 10 by the fastener 1 will be described.
First, the main body cylinder portion 20 of the bearing member 2 is inserted into the insertion hole 3a of the main body member 3 (see FIG. 2). Then, the vertical axis 14 b is inserted into the insertion hole 2 a of the bearing member 2. And C ring 4 is attached to the groove part 14c distribute | arranged above the bearing member 2 (refer FIG. 4). As a result, the support shaft 14 is prevented from being removed from the fastener 1.
Next, as shown in FIGS. 4 and 5, the bearing member 2 is inserted into the first locking portion 10a, and the engaging portion 31 is inserted into the second locking portion 10b. Thereby, the fastener 1 is installed on the lower surface of the ceiling panel 10.

Next, the support shaft 14 is rotated in the arrow X direction (see FIG. 5). As a result, the support shaft 14 rotates around the vertical axis 14b. Then, the rotational torque is transmitted to the bearing member 2 by the torque transmission means (14e, 25) (see FIG. 6). Then, the bearing member 2 rotates with respect to the main body member 3.
And the movable restraint part 20a of the bearing member 2 rotates from the position of FIG. 7 to the position shown in FIG. Thereby, the extension part 32a of the fixed restraint part 32 returns elastically, and the claw part 32b fits into the movable restraint part 20a. Thus, the movable restraint portion 20 a is locked to the fixed restraint portion 32, and the bearing member 2 is positioned so as not to rotate with respect to the main body member 3.

The neck 22 rotates from the position shown in FIG. 8 to the position shown in FIG. Thereby, the neck part 22 rotates in the 1st latching | locking part 10a. And the sliding force to the arrow Y direction of the bearing member 2 generate | occur | produces by the neck part 22 and the 1st latching | locking part 10a.
Then, the main body member 3 slides in the arrow Y direction together with the bearing member 2. Then, the engaging portion 31 is pressed against the second locking portion 10 b of the ceiling panel 10. When the main body member 3 is further slid in the arrow Y direction, the engaging portion 31 is elastically deformed. Thereby, the distance 40 between the engaging portion 31 and the bearing member 2 is narrowed.

On the other hand, the neck portion 22 is urged in the direction opposite to the arrow Y direction by the elastic repulsive force of the engaging portion 31. As a result, the pressure contact surfaces 22b and 22d of the neck portion 22 are strongly pressed against the hole wall surfaces 10a1 and 10a2 of the first locking portion 10a. Thus, the neck portion 22 and the engaging portion 31 are strongly pressed against the first locking portion 10a and the second locking portion 10b.
The head 23 rotates from the position shown in FIG. 5 to the position shown in FIG. As a result, the three retaining portions 23a formed on the head 23 rotate from the inner position of the first locking portion 10a to the outer position of the first locking portion 10a. Then, the three retaining portions 23 a project from the upper surface of the ceiling panel 10. This prevents the fastener 1 from coming off the ceiling panel 10.

  The main body member 3 is formed with an opening window 3b as shown in FIG. The opening window 3 b opens the lower side surface of the fixed restraining portion 32. An operation portion 32 c that protrudes toward the opening window 3 b is formed on the lower surface of the fixed restraining portion 32. Therefore, the fastener 1 can be easily removed from the ceiling panel 10. That is, the movable restraint portion 20a is elastically deformed by operating the operation portion 32c from the opening window 3b. In this state, the support shaft 14 and the bearing member 2 are rotated. Thereby, the fastener 1 can be removed from the ceiling panel 10.

The fastener 1 is configured as described above.
That is, the bearing member 2 rotates with respect to the main body member 3 by inputting a rotation torque (see FIG. 6). Then, the turning torque is converted into the sliding force of the bearing member 2 by the neck portion 22 (force conversion portion) (see FIGS. 8 and 12). Then, the main body member 3 slides with respect to the ceiling panel 10 together with the bearing member 2, and the engaging portion 31 of the main body member 3 is pressed against the second locking portion 10 b of the ceiling panel 10.
Accordingly, as shown in FIG. 12, the fastener 1 is attached to the ceiling panel 10 by pressure contact with the first locking portion 10a of the neck portion 22 and pressure contact with the second locking portion 10b of the engagement portion 31. These pressure contact states are formed by the neck portion 22 that converts the rotational torque into a sliding force (see FIG. 12). The neck portion 22 generates a sliding force in cooperation with the first locking portion 10a. Therefore, the configuration on the side of the neck portion 22 becomes an easy configuration by using the first locking portion 10 a of the ceiling panel 10. Thus, the construction of the fastener 1 is facilitated.

Further, the neck portion 22 is inserted into a first locking portion 10a formed in a hole shape in the ceiling panel 10, and is configured to be pressed against the hole wall surface of the first locking portion 10a by rotating in the hole. It has become. Therefore, the neck portion 22 and the first locking portion 10a have a simple configuration.
Further, as shown in FIG. 8, the neck portion 22 is configured to be disposed in a non-contact state in the hole of the first locking portion 10a, and the neck portion 22 and the first locking portion 10a are both non-contact. It is configured in a circular shape. The neck portion 22 is rotated with respect to the first locking portion 10a, so that a part of the neck portion 22 is pressed against a part of the hole edge of the first locking portion 10a.
Therefore, since the neck 22 and the first locking portion 10a are both non-circular, the neck 22 can be pressed against the first locking portion 10a with an easy configuration.
Moreover, the neck part 22 may be arrange | positioned in the non-contact state in the hole of the 1st latching | locking part 10a. Therefore, it is easy to install the neck portion 22 in the hole of the first locking portion 10a. Thus, it is easy to attach the fastener 1 to the ceiling panel 10.

Moreover, between the main body member 3 and the bearing member 2, as shown in FIG. 11, the restraining means (20a, 32) which positions the bearing member 2 non-rotatably with respect to the main body member 3 is provided. And the press contact state with respect to the 1st latching | locking part 10a of the neck part 22 and the press-contact state with respect to the 2nd latching | locking part 10b of the engaging part 31 are comprised by the restraining means (refer FIG. 12).
