Technical problem to be solved by the utility model

However, in the sunshade device as described above, when external force such as vibration is applied during traveling of the vehicle, the front concave receiving portion and the rear concave receiving portion of the slide member may be displaced inside the guide rail. For example, in the case of the middle concave receiving portion, there is a case where the front concave receiving portion and the rear concave receiving portion are displaced so as to be separated from the lower rail. In this case, when the front concave receiving portion and the rear concave receiving portion, which are temporarily separated from the lower rail wall, return to the state of being in contact with the lower rail wall, an abnormal sound (collision sound) may be generated.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a solar protection devices, this solar protection devices can restrain the production of unusual sound under the circumstances of exogenic action.

Means for solving the problems

Means for solving the above problems and their operation and effects are described below.

A sunshade device for solving the above problems includes: a shade that shades light entering a room of a vehicle from a window opening formed in a roof of the vehicle; first and second guide rails extending in the vehicle front-rear direction at both ends of the window opening in the vehicle width direction; a first slide member that slides along the first guide rail while holding a first end of the sun shade in a vehicle width direction; and a second slide member that slides along the second rail while holding a second end of the sun shade in the vehicle width direction, the first rail and the second rail each having a first guide wall and a second guide wall that oppose each other in the vehicle vertical direction, the first slide member and the second slide member each having: a body portion that slides along the first guide wall and the second guide wall while being sandwiched between the first guide wall and the second guide wall; a holding portion that slides along the second guide wall in a state of holding an end portion of the sun shade in the vehicle width direction; and a coupling portion that couples the main body portion and the holding portion such that the holding portion is relatively displaceable with respect to the main body portion about a rotational axis extending in a vehicle width direction, wherein a housing hole that houses an end portion of the sun visor in the vehicle width direction is formed in the holding portion, the sun visor has an insertion portion that is press-fitted into the housing hole of the holding portion, one of a front end portion and a rear end portion of the insertion portion in the vehicle front-rear direction is raised upward or downward with respect to the vehicle than the other, and the holding portion is urged toward the second guide wall in a state where a space is left with respect to the first guide wall by a restoring force of the insertion portion that is press-fitted into the housing hole.

In the sunshade device having the above-described configuration, since the holding portion of the slide member is biased toward the second guide wall, even when an external force such as vibration during traveling of the vehicle acts on the sunshade device, the holding portion is less likely to be displaced in a direction away from the second guide wall. Therefore, even when an external force acts, the sunshade device can suppress the holding portion from being displaced and colliding against the second guide wall. In this way, the sunshade device can suppress the occurrence of abnormal sound due to contact between the holding portion and the guide rail. The holding portion of the slide member is biased toward the second guide wall by a restoring force of the insertion portion generated by pressing the insertion portions having different shapes of the front end portion and the rear end portion into the housing hole. Therefore, the holding portion of the slide member can be biased toward the second guide wall only by the work of attaching the slide member to the sunshade.

In the above sunshade device, it is preferable that the holding portion includes a front holding portion located at a vehicle front side of the main body portion and a rear holding portion located at a vehicle rear side of the main body portion, and the coupling portion includes a front coupling portion coupling the main body portion and the front holding portion and a rear coupling portion coupling the main body portion and the rear holding portion.

For example, in the case where the sunshade device includes only the front side holding portion, the front side holding portion is biased toward the second guide wall only in the vehicle front direction of the main body portion, and therefore there is a possibility that the sliding manner between the main body portion and the guide rail is affected. In this regard, in the sunshade device having the above-described configuration, the front holding portion and the rear holding portion located in front and rear of the main body portion are biased toward the second guide wall, and therefore, the above-described situation can be avoided.

In the sunshade device, it is preferable that the main body has a first sliding surface that slides along the second guide wall, the front side holding portion and the rear side holding portion have second sliding surfaces, respectively, the second sliding surface sliding along the second guide wall, the housing holes being formed in the front holding portion and the rear holding portion, respectively, the insertion portion including a front insertion portion and a rear insertion portion, the front insertion portion is press-fitted into the receiving hole of the front holding portion, and the rear insertion portion is press-fitted into the receiving hole of the rear holding portion, in a state where the front insertion portion is press-fitted into the housing hole of the front holding portion and the rear insertion portion is press-fitted into the housing hole of the rear holding portion, an angle formed between the first sliding surface and the second sliding surface is less than 180 degrees.

The sun shading device with the structure can ensure that the angle formed between the first sliding surface and the second sliding surface is less than 180 degrees only by assembling the sliding component on the sun shading component. When the sliding member is inserted into the guide rail, for example, when the angle formed between the first sliding surface and the second sliding surface is 180 degrees, the front holding portion and the rear holding portion of the sliding member tend to return to the state before insertion. That is, the front holding portion and the rear holding portion of the slide member tend to press the second guide wall of the guide rail. As a result, the front holding portion and the rear holding portion are biased toward the second guide wall in a state where the slide member is inserted into the guide rail. In this way, the sunshade device can bias the front holding portion and the rear holding portion toward the second guide wall without providing a separate biasing member such as a spring.

In the above sunshade device, it is preferable that the first guide wall is located above the second guide wall with respect to the vehicle, a front end portion of the front insertion portion is raised below the vehicle with respect to a rear end portion of the front insertion portion, and a rear end portion of the rear insertion portion is raised below the vehicle with respect to the front end portion of the rear insertion portion.

In the sunshade device having the above configuration, in a state where the sliding member is assembled to the sunshade, the front end portion of the front insertion portion is more easily compressed than the rear end portion in the accommodating hole of the front holding portion, and the rear end portion of the rear insertion portion is more easily compressed than the front end portion in the accommodating hole of the rear holding portion. Therefore, the front end portion of the front holding portion is pressed downward toward the vehicle by the front end portion of the front insertion portion that is compressed, and the rear end portion of the rear holding portion is pressed downward toward the vehicle by the rear end portion of the rear insertion portion that is compressed. As a result, the angle formed between the first sliding surface and the second sliding surface is less than 180 degrees. In this way, in the sunshade device, when the slide member is inserted into the guide rail, the front side holding portion and the rear side holding portion can be biased toward the second guide wall by the shape of the sunshade.

In the sunshade device, it is preferable that the front insertion portion and the rear insertion portion have first engaging portions, respectively, and the front holding portion and the rear holding portion have second engaging portions, respectively, and the second engaging portions are engaged with the first engaging portions.

In the sunshade device having the above configuration, when the front insertion portion and the rear insertion portion of the sunshade are pressed into the housing hole of the slide member, the first engagement portion is engaged with the second engagement portion. Therefore, the sunshade device can suppress the sliding member assembled to the sunshade from being detached from the sunshade.

Effect of the utility model

The sunshade device can restrain the generation of abnormal sound under the action of external force.

Detailed Description

An embodiment of a vehicle provided with a sunshade device will be described below.

As shown in fig. 1, a vehicle 10 includes a vehicle body 13, a sunroof apparatus 20, and a sunshade apparatus 30, the vehicle body 13 having a window opening 12 formed in a roof 11, the sunroof apparatus 20 opening and closing the window opening 12, and the sunshade apparatus 30 blocking light entering a room of the vehicle 10 through the window opening 12. In the following description, the components of the vehicle 10 will be described based on the direction in which the vehicle 10 is mounted. The vehicle longitudinal direction is also referred to as "longitudinal direction", the vehicle width direction is referred to as "width direction", and the vehicle vertical direction is referred to as "vertical direction".

The sunroof device 20 includes a glass panel 21, and the glass panel 21 moves between an open position where the window opening 12 is opened and a closed position where the window opening 12 is closed. The glass panel 21 is moved between the closed position and the open position by driving of an actuator not shown.

As shown in fig. 2, the sunshade device 30 includes a sunshade panel 40 that shades light entering the interior of the vehicle 10 from the window opening 12, guide rails 50 extending in the front-rear direction at both ends of the window opening 12 of the roof 11, and a slide member 60 that slides along the guide rails 50 while holding the ends of the sunshade panel 40 in the width direction.

First, the sunshade panel 40 will be described in detail. In the present embodiment, the sunshade panel 40 is an example of a "sunshade". As shown in fig. 3 and 4 (a), the sunshade panel 40 includes a panel main body 41 having a plate shape and a plurality of assembling portions 42 to which the slide members 60 are attached. As shown in fig. 2, a mounting hole 44 to which a handle 43 (see fig. 1) is attached is formed at the front end of the sunshade panel 40. The sunshade panel 40 is formed by, for example, pressing a laminate including a plurality of sheets having different materials, such as a skin layer, an inner skin layer, a glass fiber layer, a foamed polyurethane layer, and an adhesive film layer. That is, the sunshade panel 40 can be formed into a shape by a mold.

As shown in fig. 3, the assembling portions 42 are formed at four corners of the panel body 41, and include an assembling portion 42F near the front end and an assembling portion 42R near the rear end. The assembly portion 42 has a front insertion portion 45 and a rear insertion portion 46 that protrude outward in the width direction. The front insertion portion 45 and the rear insertion portion 46 are disposed with a gap in the front-rear direction, and the front insertion portion 45 is located closer to the front end of the panel main body 41 than the rear insertion portion 46. As shown in fig. 4 (a) to (c), the cross-sectional shapes of the front insertion portion 45 and the rear insertion portion 46 orthogonal to the protruding direction are substantially rectangular. A locking hole 451 as an example of the "first locking portion" is formed through the center portion of the front insertion portion 45 in the thickness direction of the panel body 41, and a locking hole 461 as an example of the "first locking portion" is formed through the center portion of the rear insertion portion 46 in the thickness direction of the panel body 41.

As shown in fig. 4 (b), the thickness W2 of the front end portion of the front insertion portion 45 is greater than the thickness W1 of the rear end portion. Specifically, the upper surface of the front insertion portion 45 is a flat surface, and the lower surface of the front end portion of the front insertion portion 45 is raised downward from the lower surface of the rear end portion of the front insertion portion 45. Similarly, as shown in fig. 4 (c), the rear end portion of the rear insertion portion 46 has a thickness W2 greater than the thickness W1 of the front end portion. Specifically, the upper surface of the rear insertion portion 46 is a flat surface, and the lower surface of the rear end portion of the rear insertion portion 46 is raised downward from the lower surface of the front end portion of the rear insertion portion 46. In the following description, the raised portion at the front end of the front insertion portion 45 is referred to as "thick portion 452", and the raised portion at the rear end of the rear insertion portion 46 is referred to as "thick portion 462".

Next, the guide rail 50 will be explained.

As shown in fig. 2, the guide rail 50 includes a first guide rail 50R and a second guide rail 50L, the first guide rail 50R being disposed at a first end of the window opening 12 in the width direction, and the second guide rail 50L being disposed at a second end of the window opening 12 in the width direction. The rail 50 preferably has a shape that conforms to the roof 11 of the vehicle 10. For example, the guide rail 50 may be a guide rail that extends linearly in the front-rear direction when the vehicle 10 is viewed from the side, or may be a guide rail that curves so as to protrude upward.

As shown in fig. 5, in a cross-sectional view orthogonal to the longitudinal direction, the guide rail 50 includes a first guide wall 51 and a second guide wall 52 intersecting with the vertical direction, and a third guide wall 53 intersecting with the width direction. First guide wall 51 is located at a position above second guide wall 52 with a space left between second guide wall 52. That is, the first guide wall 51 and the second guide wall 52 are opposed to each other in the vertical direction. The third guide wall 53 connects the end portions of the first guide wall 51 and the second guide wall 52 in the width direction to each other. In this manner, the guide rail 50 has a substantially C-shaped cross-sectional shape that opens inward in the width direction. The guide rail 50 includes, in addition to the first guide wall 51, the second guide wall 52, and the third guide wall 53, a wall portion that slides on a functional member for opening and closing the glass panel 21 of the sunroof apparatus 20, a wall portion to which an interior member is attached, a wall portion that is assembled to the vehicle body 13, and the like. Although the guide rail 50 shown in fig. 5 is the first guide rail 50R, the second guide rail 50L has the same shape except for the point of bilateral symmetry.

Next, the sliding member 60 will be explained.

As shown in fig. 3, the slide member 60 includes a slide member 60F and a slide member 60R, the slide member 60F is attached to the attachment portion 42F near the front end of the sunshade panel 40, and the slide member 60R is attached to the attachment portion 42R near the rear end of the sunshade panel 40. As shown in fig. 2, in the present embodiment, the two slide members 60F, 60R attached to the first end of the sunshade panel 40 in the width direction correspond to an example of a "first slide member", and the two slide members 60F, 60R attached to the second end of the sunshade panel 40 in the width direction correspond to an example of a "second slide member".

As shown in fig. 6 and 7, the slide member 60 includes a main body portion 61, a front holding portion 62, and a rear holding portion 63, the main body portion 61 slides along the first guide wall 51 and the second guide wall 52, and the front holding portion 62 and the rear holding portion 63 slide along the second guide wall 52. The slide member 60 includes a front coupling portion 64, a rear coupling portion 65, and a leaf spring 66, the front coupling portion 64 couples the main body portion 61 and the front holding portion 62, the rear coupling portion 65 couples the main body portion 61 and the rear holding portion 63, and the leaf spring 66 is assembled to the main body portion 61. The sliding member 60 is a resin molded product having appropriate elasticity. Although the slide member 60 shown in fig. 6 and 7 is the slide member 60 that slides along the first guide rail 50R, the slide member 60 that slides along the second guide rail 50L has the same shape except for the point of bilateral symmetry.

As shown in fig. 6 and 7, the body 61 has an upper wall 611 and a bottom wall 612 extending in the front-rear direction, and side walls 613 and 614 connecting the upper wall 611 and the bottom wall 612. The upper wall 611 has a beam-like structure supported at both ends by the side walls 613 and 614 at the front and rear ends. That is, the upper wall 611 is configured to be vertically movable with respect to both end portions at the center portion in the longitudinal direction. As shown in fig. 7, the upper wall 611 has a pressing part 615 at a central portion in the longitudinal direction, and the pressing part 615 slides along the first guide wall 51 in a state where the first guide wall 51 is pressed. On the other hand, the lower surface of the bottom wall 612 is the first sliding surface S1 that slides along the second guide wall 52.

As shown in fig. 6 and 7, the front holding portion 62 and the rear holding portion 63 each have an upper wall 671 and a bottom wall 67 extending in the front-rear direction, and side walls 673 and 674 connecting the upper wall 671 and the bottom wall 672. As shown in fig. 7, a receiving hole 621 into which the front insertion portion 45 of the sunshade panel 40 is press-fitted (inserted) is formed in the front holding portion 62, and a receiving hole 631 into which the rear insertion portion 46 of the sunshade panel 40 is press-fitted (inserted) is formed in the rear holding portion 63. The receiving holes 621 and 631 are portions that receive the end portions of the sunshade panel 40 in the width direction. The receiving holes 621 and 631 are opened inward in the width direction.

As shown in fig. 7, the upper wall 671 has a locking claw 675, and the locking claw 675 is an example of a "second locking portion" extending toward the bottom wall 672. The height of the portions of the front holding portion 62 and the rear holding portion 63 that are housed in the guide rail 50 is smaller than the height of the main body portion 61. Therefore, the upper walls 671 of the front side holding portion 62 and the rear side holding portion 63 do not have a portion that slides along the first guide wall 51 of the guide rail 50. On the other hand, the bottom surfaces of the bottom walls 672 of the front side holding portion 62 and the rear side holding portion 63 are second sliding surfaces S2 that slide along the second guide walls 52 of the guide rail 50. Here, when the sliding member 60 is viewed alone, the second sliding surfaces S2 of the front side holding portion 62 and the rear side holding portion 63 are flush with the first sliding surface S1 of the body portion 61. In other words, the angle θ formed between the second sliding surface S2 and the first sliding surface S1 is substantially 180 degrees.

In the front holding portion 62 and the rear holding portion 63, the housing holes 621 and 631 are spaces surrounded by the upper wall 671, the bottom wall 672, and the side walls 673 and 674. The upper and lower surfaces of the receiving holes 621 and 631 extend in the front-rear direction, and the side surfaces of the receiving holes 621 and 631 extend in the vertical direction. The front ends of the lower surfaces of the receiving holes 621 and 631 are inclined surfaces inclined upward as they extend forward, and the rear ends of the lower surfaces of the receiving holes 621 and 631 are inclined surfaces inclined upward as they extend rearward. Therefore, the distance between the upper and lower surfaces of the receiving holes 621 and 631 excluding the front and rear ends is substantially constant width W3.

As shown in fig. 4 and 7, in the present embodiment, the cross-sectional area of the receiving hole 621 of the front holding portion 62 of the slide member 60 is smaller than the cross-sectional area of the front insertion portion 45 of the sunshade panel 40, and the cross-sectional area of the receiving hole 631 of the rear holding portion 63 of the slide member 60 is smaller than the cross-sectional area of the rear insertion portion 46 of the sunshade panel 40. Specifically, the length of the receiving hole 621 of the front holding portion 62 is substantially equal to the length of the front insertion portion 45, and the length of the receiving hole 631 of the rear holding portion 63 is substantially equal to the length of the rear insertion portion 46 in the front-rear direction. In the vertical direction, width W3 of receiving hole 621 of front holding portion 62 is substantially equal to thickness W1 of the portion of front insertion portion 45 other than the front end portion, and width W3 of receiving hole 631 of rear holding portion 63 is substantially equal to thickness W1 of the portion of rear insertion portion 46 other than the rear end portion. Further, in the vertical direction, width W3 of receiving hole 621 of front holding portion 62 is shorter than thickness W2 of the front end portion of front insertion portion 45, and width W3 of receiving hole 631 of rear holding portion 63 is shorter than thickness W2 of the rear end portion of rear insertion portion 46. That is, since the thick portion 452 is formed in the front insertion portion 45, the cross-sectional area of the receiving hole 621 of the front holding portion 62 is smaller than the cross-sectional area of the front insertion portion 45, and since the thick portion 462 is formed in the rear insertion portion 46, the cross-sectional area of the receiving hole 631 of the rear holding portion 63 is smaller than the cross-sectional area of the rear insertion portion 46.

As shown in fig. 7, the front connecting portion 64 connects the lower portion of the side wall 613 of the body 61 and the lower portion of the side wall 674 of the front holding portion 62, and the rear connecting portion 65 connects the lower portion of the side wall 614 of the body 61 and the lower portion of the side wall 674 of the rear holding portion 63. That is, in the slide member 60, a gap GP is formed between the upper portion of the side wall 613 of the body 61 and the upper portion of the side wall 674 of the front holding portion 62, and a gap GP is formed between the upper portion of the side wall 614 of the body 61 and the upper portion of the side wall 674 of the rear holding portion 63. Therefore, the front connecting portion 64 connects the front holding portion 62 and the main body portion 61 such that the front holding portion 62 is rotatable about a rotation axis extending in the width direction with respect to the main body portion 61. Similarly, the rear connecting portion 65 connects the rear holding portion 63 and the main body portion 61 such that the rear holding portion 63 is rotatable about a rotation axis extending in the width direction with respect to the main body portion 61. However, the range in which the front holding portion 62 and the rear holding portion 63 can rotate is limited to the range in which the front coupling portion 64 and the rear coupling portion 65 can elastically deform.

Both ends of the plate spring 66 in the longitudinal direction are supported by the side walls 613 and 614 of the main body 61. The plate spring 66 biases the upper wall 611 (pressing portion 615) of the body 61 upward while being supported by the side walls 613 and 614 of the body 61. The force applied by the leaf spring 66 to the upper wall 611 of the main body 61 is proportional to the force required to move the sunshade panel 40 forward and backward in the sunshade 30.

Next, the assembly of the sunshade device 30 will be described.

As shown in fig. 3 and 8, when the sunshade device 30 is assembled, the slide member 60 is assembled to each assembling portion 42 of the sunshade panel 40. Specifically, the slide member 60 is pressed against the sunshade panel 40 in a state where the positions of the front insertion portion 45 and the rear insertion portion 46 of the sunshade panel 40 are aligned with the positions of the receiving holes 621 of the front holding portion 62 and the receiving holes 631 of the rear holding portion 63 of the slide member 60. Then, the front insertion portion 45 of the sunshade panel 40 is press-fitted into the receiving hole 621 of the front holding portion 62 of the slide member 60, and the rear insertion portion 46 of the sunshade panel 40 is press-fitted into the receiving hole 631 of the rear holding portion 63 of the slide member 60. Then, as shown in fig. 8 and 9, the locking claw 675 of the slide member 60 is locked in the locking holes 451, 461 of the sunshade panel 40.

When the front insertion portion 45 and the rear insertion portion 46 of the sunshade panel 40 are press-fitted into the receiving holes 621 and 631 of the slide member 60, the front insertion portion 45 and the rear insertion portion 46 are compressed and deformed. At this time, the front end portion of the front insertion portion 45 formed with the thick portion 452 and the rear end portion of the rear insertion portion 46 formed with the thick portion 462 are more largely compressed and deformed than other portions. Therefore, as shown by the solid arrows in fig. 10, the front end of the front insertion portion 45 presses the front end of the front holding portion 62 downward, and the rear end of the rear insertion portion 46 presses the rear end of the rear holding portion 63 downward. Then, as shown in fig. 10, the front holding portion 62 and the rear holding portion 63 are displaced from the state shown by the two-dot chain line to the state shown by the solid line. That is, the front holding portion 62 is inclined downward with respect to the body portion 61 with the front connecting portion 64 as a rotation center, and an angle θ formed between the second sliding surface S2 of the front holding portion 62 and the first sliding surface S1 of the body portion 61 is smaller than 180 degrees. Similarly, the rear holding portion 63 is inclined downward with respect to the body portion 61 with the rear coupling portion 65 as a rotation center, and the angle θ formed between the second sliding surface S2 of the rear holding portion 63 and the first sliding surface S1 of the body portion 61 is smaller than 180 degrees.

As shown in fig. 2 and 3, the sunshade 30 is configured by inserting a slide member 60 assembled to the sunshade 30 between the first guide wall 51 and the second guide wall 52 of the guide rail 50. In a state where the slide member 60 is inserted into the guide rail 50, the pressing portion 615 of the body portion 61 comes into contact with the first guide wall 51 and the first sliding surface S1 of the body portion 61 comes into contact with the second guide wall 52. In the same state, in a state where a space is formed between the front holding portion 62 and the rear holding portion 63 and the first guide wall 51, the second sliding surface S2 of the front holding portion 62 and the second sliding surface S2 of the rear holding portion 63 come into contact with the second guide wall 52. That is, when the sunshade panel 40 is moved in the front-rear direction, the pressing portion 615 of the main body portion 61 slides along the first guide wall 51, and the first sliding surface S1 of the main body portion 61 slides along the second guide wall 52. In this case, the front holding portion 62 and the rear holding portion 63 slide along the second guide wall 52 with a space left between them and the first guide wall 51.

The operation and effect of the present embodiment will be described.

(1) As shown in fig. 11, when the sliding member 60 is inserted into the guide rail 50, the front holding portion 62 and the rear holding portion 63 press the second guide wall 52, and the first sliding surface S1 of the main body portion 61, the second sliding surface S2 of the front holding portion 62, and the second sliding surface S2 of the rear holding portion 63 are flush with each other. Therefore, the front holding portion 62 and the rear holding portion 63 tend to return to the state before insertion into the guide rail 50 shown in fig. 10. That is, as shown by the solid arrows in fig. 11, the distal end of the front holding portion 62 is biased toward the second guide wall 52, and the rear end of the rear holding portion 63 is biased toward the second guide wall 52. In other words, the front holding portion 62 and the rear holding portion 63 are biased toward the second guide wall 52 by the restoring force of the front insertion portion 45 and the rear insertion portion 46 generated by press-fitting the front insertion portion 45 and the rear insertion portion 46 into the housing holes 621 and 631. Therefore, when an external force such as vibration is applied to the sunshade device 30 during traveling of the vehicle, the front holding portion 62 and the rear holding portion 63 of the slide member 60 are not easily moved inside the guide rail 50.

For example, even when an upward load acts on the sunshade panel 40, the front holding portion 62 and the rear holding portion 63 of the slide member 60 are biased downward, and therefore the front holding portion 62 and the rear holding portion 63 are less likely to separate from the second guide wall 52. Therefore, when the front holding portion 62 and the rear holding portion 63 separated from the second guide wall 52 come into contact with the second guide wall 52 again, the abnormal sound is less likely to be generated. In this way, the sunshade device 30 can suppress abnormal sounds (collision sounds) generated by the contact between the front holding portion 62 and the rear holding portion 63 and the second guide wall 52.

In a state where the slide member 60 is inserted into the guide rail 50, a space is formed between the front holding portion 62 and the rear holding portion 63, and the first guide wall 51. Therefore, the sunshade device 30 can also suppress the generation of abnormal sound (collision sound) due to the contact between the front holding portion 62 and the rear holding portion 63 and the first guide wall 51.

(2) For example, in the case where the sunshade device 30 includes only the front holding portion 62, the front holding portion 62 is biased toward the second guide wall 52 only in front of the main body portion 61, and therefore the main body portion 61 may be difficult to smoothly slide along the guide rail 50. For example, there is a possibility that the first sliding surface S1 of the main body portion 61 becomes partially unable to slide along the second guide wall 52. In this regard, in the sunshade device 30 of the present embodiment, the front holding portion 62 and the rear holding portion 63 located in the front and rear of the main body portion 61 are biased toward the second guide wall 52, and therefore, the above-described situation can be avoided.

(3) The sunshade device 30 is assembled to the sunshade panel 40 only by the sliding member 60, so that the angle θ formed between the first sliding surface S1 and the second sliding surface S2 is less than 180 degrees. Therefore, the sunshade device 30 can urge the front holding portion 62 and the rear holding portion 63 toward the second guide wall 52 only by inserting the slide member 60 into the guide rail 50 without providing an urging member such as a spring separately.

(4) In the sunshade 30, in a state where the slide member 60 is assembled to the sunshade panel 40, the front end portion of the front insertion portion 45 is more compressed and deformed than the rear end portion thereof, and the rear end portion of the rear insertion portion 46 is more compressed and deformed than the front end portion thereof, inside the housing holes 621 and 631. Therefore, the front end of the front insertion portion 45 presses the front end of the front holding portion 62 downward, and the rear end of the rear insertion portion 46 presses the rear end of the rear holding portion 63 downward. As a result, the angle θ formed between the first sliding surface S1 and the second sliding surface S2 is less than 180 degrees. As described above, when the slide member 60 is inserted into the guide rail 50, the sunshade device 30 can urge the front holding portion 62 and the rear holding portion 63 toward the second guide wall 52. That is, when considering the application of the sunshade device 30 to different vehicle types, it is not necessary to change the shape of the slide member 60 according to the vehicle type. In other words, in the sunshade device 30, unlike the sunshade panel 40, the slide member 60, which does not need to be changed in shape regardless of the size of the window opening 12, does not need to be changed in shape for each vehicle type.

(5) In the sunshade device 30, when the front insertion portion 45 and the rear insertion portion 46 of the sunshade panel 40 are press-fitted into the housing holes 621 and 631 of the slide member 60, the locking claw 675 is locked in the locking holes 451 and 461. Therefore, the sunshade device 30 can suppress the sliding member 60 assembled to the sunshade panel 40 from being detached from the sunshade panel 40.

(6) In the sunshade device 30, the sliding member 60 has a leaf spring 66, and the leaf spring 66 adjusts the force pressing the first guide wall 51. The front holding portion 62 and the rear holding portion 63 of the slide member 60 are configured not to contact the first guide wall 51. Therefore, the sunshade device 30 can easily manage the sliding resistance when the sunshade panel 40 is opened and closed, according to the elastic modulus and the elastic deformation amount of the plate spring 66.

This embodiment can be modified and implemented as follows. The present embodiment and the following modifications can be implemented in combination with each other within a range not technically contradictory.

The shapes of the front insertion portion 45 and the rear insertion portion 46 of the sunshade panel 40 may be appropriately changed. For example, the positions of the thick portions 452 and 462 may be changed. The thick portions 452 and 462 may have a shape in which the thickness gradually changes in the front-rear direction.

In the sunshade panel 40, the thick portion 452 of the front insertion portion 45 may be formed separately from the sunshade panel 40. For example, after the sunshade panel 40 is molded, a member corresponding to the thick portion 452 may be attached to the sunshade panel 40 to form a portion corresponding to the front insertion portion 45. The same applies to the thick portion 462 of the rear insertion portion 46.

The slide member 60 may have one of the front holding portion 62 and the rear holding portion 63. When the slide member 60 includes only the front holding portion 62, the front end portion of the front insertion portion 45 may be raised downward relative to the rear end portion as in the above-described embodiment, or the rear end portion of the front insertion portion 45 may be raised upward relative to the front end portion. In the case where the slide member 60 includes only the rear holding portion 63, the rear end portion of the rear insertion portion 46 may be raised downward relative to the front end portion as in the above-described embodiment, or the front end portion of the front insertion portion 45 may be raised upward relative to the rear end portion.

In the slide member 60, the main body 61, the front holding portion 62, and the rear holding portion 63 may be formed separately. In this case, for example, the front connecting portion 64 serves as a shaft that rotatably connects the main body portion 61 and the front holding portion 62, and the rear connecting portion 65 serves as a shaft that rotatably connects the main body portion 61 and the rear holding portion 63.

Preferably, the angle θ formed between the first sliding surface S1 and the second sliding surface S2 is appropriately set in a state where the sliding member 60 is assembled to the sunshade panel 40. For example, the angle θ may be set as appropriate according to the bending form of the guide rail 50 and the size of the input to the sunshade device 30.

The slide member 60 may be configured such that the front holding portion 62 and the rear holding portion 63 are biased toward the first guide wall 51 when inserted into the guide rail 50.

The sliding member 60 may not have the first sliding surface S1 and the second sliding surface S2. That is, the slide member 60 may have a portion other than a surface that slides along the second guide wall 52.

The sunshade panel 40 may be provided with a locking claw. In this case, it is preferable that the slide member 60 is provided with a locking hole to which the locking claw of the sunshade panel 40 is locked.

The locking holes 451, 461 may not be provided in the sunshade panel 40, or the locking claw 675 may not be provided in the slide member 60.

The sunshade device 30 may be an electric sunshade device that is opened and closed by driving an actuator.
