Here, as shown in FIG. 8, the sunshade 33 is allowed to slide backward in the vehicle when the first wire 64 moves as indicated by an arrow G.
Thereby, the movement of the first wire 64 from the wire release position P6 toward the wire locking position P5 is prevented, so that the sunshade 33 can be prevented from sliding to the rear of the vehicle.

Therefore, when the right sun visor 35 is disposed at the downward anti-glare position P2, the sun shade 33 can be restricted from sliding toward the occupant.
Thereby, it can prevent that the right sun visor 35 arrange | positioned at the glare-proof position P2 approaches a passenger | crew side.

By the way, when the lock mechanism 37 is configured to lock the first wire 64 with the engagement member 83, the engagement member 83 can be locked at an arbitrary position of the first wire 64.
As a result, when the right sun visor 35 is disposed in the downward anti-glare position P2 in a state where the sun shade 33 (see FIG. 4) is disposed at an arbitrary position, the engagement member 83 is engaged with the first wire 64. Thus, the sliding movement of the sunshade 33 can be restricted.

By the way, when the sun shade 33 is pulled strongly with the lock mechanism 37 engaged with the first wire 64, the tensile force generated by the pull is transmitted from the sun shade 33 to the first wire 64.
Here, since the first wire 64 is engaged with the lock mechanism 37, the tensile force transmitted to the first wire 64 can be supported (blocked) by the lock mechanism 37 so as not to be transmitted to the right sun visor 35.

Therefore, the right sun visor 35 can be prevented from swinging from the anti-glare position P2 to the folding position P1.
Thereby, when the sun shade 33 is pulled strongly, there is no possibility that the right sun visor 35 swings from the anti-glare position P2 to the folding position P1.
Therefore, the engagement of the first wire 64 by the lock mechanism 37 can be prevented and the sliding movement of the sunshade 33 toward the occupant side can be restricted.

On the other hand, as shown in FIG. 10, when a tensile force F <b> 2 is applied to the first wire 64 in a state in which the first wire 64 is locked by the engaging member 83, the engaging member 83 is connected to the first spring member 84. It moves (drives) toward the wire release position P6 against the urging force.
Accordingly, the first wire 64 is allowed to move from the wire locking position P5 toward the wire release position P6 (in the direction of arrow C shown in FIG. 8).

Here, as shown in FIG. 8, the sunshade 33 is allowed to slide forward in the vehicle when the first wire 64 moves as indicated by an arrow C.
Accordingly, by allowing the first wire 64 to move from the wire locking position P5 toward the wire release position P6, the sunshade 33 can be allowed to slide forward in the vehicle.

  That is, as described above, the lock mechanism 37 is a mechanism that can prevent the sunshade 33 from sliding to the rear of the vehicle.

As described above, the sunshade structure 20 shown in FIGS. 7 to 10 changes the relative positions of the first and second wires 64 and 65 with respect to the sunshade 33 in accordance with the sliding movement of the sunshade 33, thereby changing the first wire 64. An engaging lock mechanism 37 is provided on the sunshade 33.
Therefore, the driving of the first wire 64 can be regulated by engaging the lock mechanism 37 with the first wire 64.
Thereby, it can suppress that the relative position of the 1st wire 64 with respect to the sun shade 33 changes, and can control the sliding movement of the sun shade 33. FIG.

  Further, the sun shade 33 is provided with a lock mechanism 37 and a right sun visor 35. Then, the operation unit (that is, the operation button) 94 of the lock mechanism 37 can be operated by swinging the right sun visor 35.

As described above, by directly operating the operation button 94 by the swing movement of the right sun visor 35, it is not necessary to provide a complicated mechanism (for example, a mechanism for transmitting an electrical signal) or the like as the operation unit of the lock mechanism 37.
Thereby, since the operation part of the lock mechanism 37 can be simplified, the lock mechanism 37 can be made compact.

On the other hand, when the operation part of the lock mechanism is provided on the vehicle body side, for example, it is necessary to provide a complicated mechanism for transmitting an electric signal in order to operate the operation part with an electric signal or the like.
For this reason, it is difficult to simplify the operation part of the lock mechanism, and it is difficult to make the lock mechanism compact.

Further, the sun shade structure 20 includes the first and second wires 64 and 65 to form the sun visor synchronization mechanism 36, so that when the lock mechanism 37 is locked to the first wire 64, the left and right sliding portions 41, 42 can be kept stationary in a synchronized state.
Therefore, the sunshade 33 can be stopped in a state in which the posture is maintained parallel to the vehicle longitudinal direction.
Thereby, when the locking state of the lock mechanism 37 with respect to the first wire 64 is released, the sliding movement of the sunshade 33 in the vehicle front-rear direction can be started smoothly.

As shown in FIG. 6, the right sun visor 35 has a sun visor clip 108 attached to the shaft support mechanism 45.

Thereby, in the state where the right sun visor 35 is disposed at the folding position P1, a restoring force is generated in which the flat locking piece 108a tries to restore toward the flat portion 45a.

With this restoring force, a biasing force (hereinafter referred to as “clip biasing force”) is generated in the sun visor clip 108, and the right sun visor 35 can be biased toward the folding position P1 with this clip biasing force.
That is, the right sun visor 35 can be held at the folding position P1 by the clip biasing force.

As shown in FIG. 11, the right sun visor 35 includes a sun visor clip 108 arranged in an operation button 94 (button portion 94b) in the vehicle front-rear direction.
Specifically, the sun visor clip 108 and the operation button 94 are arranged side by side in the vehicle front-rear direction, and the sun visor clip 108 is provided in front of the operation button 94 in the vehicle.
In other words, the operation button 94 is disposed within the range of the clip width W of the sun visor clip 108.

Therefore, as shown by the imaginary line in FIG. 6, the clip urging force of the sun visor clip 108 can be efficiently transmitted to the operation button 94 in a state where the right sun visor 35 is disposed at the folding position P1.
