JP 2016-22838 A

In the vehicle as described above, the components of the sunroof device, such as the guide rails, the functional parts, and the arms, are arranged side by side on both sides of the roof opening in the width direction. Therefore, in order to secure a wide opening for the roof opening, it is desirable to minimize the area occupied by the components of the sunroof device.

Means for solving the above problems and their effects will be described below.
A sunroof device that solves the above problems is a sunroof device that is positioned between a fully closed position that fully closes a roof opening of a vehicle, a tilt-up position in which the rear end is raised above the fully closed position, and a fully open position that fully opens the roof opening. a movable panel to be actuated; support brackets that support the movable panel on both sides in the width direction of the movable panel and extend in the front-rear direction; a rail unit that serves as a direction, a front support portion that supports the support bracket, a rear support portion that supports the support bracket behind the front support portion, and is displaced in the front-rear direction along the rail unit. a drive shoe for driving the front support and the rear support, a power transmission member for transmitting power from the drive shoe to the rear support, and a deflector for adjusting airflow around the roof opening, and the front support portion displaces in the front-rear direction along the rail unit based on the power transmitted from the drive shoe, thereby moving the movable panel between the tilt-up position and the fully-open position. The rear support portion has an actuated front link, and the rear support portion rotates about the axis extending in the width direction based on the power transmitted from the power transmission member, thereby moving between the fully closed position and the tilt-up position. and the deflector is deployed in a space in front of the roof opening when the movable panel is opened toward the fully open position, and the movable panel is actuated by the a screen that is retracted when closed toward a fully closed position; and a rail unit that is disposed on both sides of the roof opening in the width direction and supports the screen at a tip end while the base end is the rail unit. and an arm rotatably supported about the axis extending in the width direction, and in a situation in which the movable panel is positioned at the fully closed position, at least a part of the front link is connected to the arm and the Positioned side by side in the width direction, at least part of the rear link is positioned side by side with the arm in the longitudinal direction.

In the sunroof device configured as described above, the front link is displaced in the longitudinal direction along the rail unit when the movable panel is operated between the tilt-up position and the fully open position. At this time, since the front link and the rear link are shifted in the width direction, the amount of displacement of the front link in the front-rear direction can be increased. In addition, since the rear link and the arm are not shifted in the width direction, the area occupied by the components of the sunroof device is reduced in the width direction. Therefore, the sunroof device can have a wide roof opening.

In the sunroof device, it is preferable that the rear link is arranged inward of the front link in the width direction.
For example, when the four corners of the roof opening are rounded in plan view in the vertical direction, the length of the roof opening in the width direction may become shorter toward the rear. In this case, among the components of the sunroof device, those components that operate near the rear end of the roof opening are preferably arranged away from the side edges of the roof opening. In this regard, in the sunroof device having the above configuration, the rear link that is displaced between the tilted position and the upright position is arranged inward of the front link in the width direction. In other words, the sunroof device positions the rear link away from the side edges of the roof opening. Therefore, the sunroof device can arrange the rear link further rearward while avoiding interference between the rear link and the opening edge of the roof opening. Therefore, the amount of rearward movement of the front link when opening the movable panel is increased. As a result, when the movable panel is displaced to the fully open position, the portion of the roof opening not covered by the movable panel becomes wider. Specifically, the distance in the front-rear direction between the front end of the roof opening and the front end of the movable panel located at the fully open position increases.

In the sunroof device, the deflector has an arm biasing portion that biases the arm in the direction in which the screen is deployed, and the drive shoe displaces in the longitudinal direction along the rail unit. It is preferable to have a pressing portion that slides with the arm, and the pressing portion rotates the arm in a direction to retract the screen when the drive shoe is displaced forward.

In the sunroof device having the above configuration, the screen can be retracted by the pressing portion of the drive shoe. Here, since the pressing portion is displaced along the rail unit, the sunroof device can suppress excessive rotation of the arm when the screen is retracted. In other words, the sunroof device makes it easier to manage the position of the arm when the screen is retracted.

The sunroof device can have a wide roof opening.

The first recess 153 is located near the base end of the rear link 150 , and the second recess 154 is located near the tip of the rear link 150 .

The covering portion 152 has first sliding surfaces 155 and 156 and a second sliding surface 157 . The first sliding surface 155 includes the inner side surface of the first recess 153 , and the first sliding surface 156 includes the outer side surface of the covering portion 152 and the inner side surface of the first recess 153 . In other words, the first sliding surface 155 includes an inclined surface inclined with respect to the longitudinal direction of the rear link 150, and the first sliding surface 156 includes a horizontal surface extending in substantially the same direction as the longitudinal direction of the rear link 150 and the rear link. 150 and an inclined surface slanted with respect to the longitudinal direction. On the other hand, the second sliding surface 157 includes the inner side surface of the second concave portion 154 . In other words, second sliding surface 157 includes an inclined surface that is inclined with respect to the longitudinal direction of rear link 150 .

The tip of the rear link 150 supports the slider 161 via a connecting pin whose axial direction is the width direction. The slider 161 is rotatable around an axis extending in the width direction with respect to the rear link 150 . The rotation axis of the slider 161 intersects the bottom surface of the second recess 154 . The rear link 150 supports the slider 161 on the side opposite to the side on which the first recess 153 and the second recess 154 are provided.

The link support portion 162 supports the base end portion of the rear link 150 via a connecting pin whose axial direction is the width direction. Thus, the rear link 150 is rotatable around the axis extending in the width direction. In the following description, the position where the rear link 150 is tilted as shown in FIGS. 10 and 11 is also called the "tilted position", and the position where the rear link 150 is raised from the tilted position is also called the "upright position". That is, the rear link 150 is rotationally displaced between the tilted position and the standing position.

The link biasing portion 163 is formed in a block shape from an elastomer such as rubber or resin. The link biasing portion 163 is fixed at a position near the tip of the rear link 150 . Specifically, the link biasing portion 163 is fixed to the downward facing surface of the rear link 150 in the posture shown in FIG.

As shown in FIGS. 4 and 5, the rear support portion 140 is positioned at the rear end portion of the rail unit 60 where the intermediate wall 73 does not exist. In other words, the rear support portion 140 is housed across the first housing space 75 and the second housing space 76 of the rail unit 60 .

The slider 161 sandwiches the support bracket 100 from both the width direction and the vertical direction. Thus, the slider 161 movably supports the support bracket 100 . A portion of the support bracket 100 supported by the slider 161 is located behind a portion connected to the front link 130 . In this respect, it can be said that the rear support portion 140 supports the support bracket 100 behind the front support portion 120 . It is preferable that the manner in which the support bracket 100 is supported by the slider 161 is appropriately changed according to the cross-sectional shape of the support bracket 100 .

The link support portion 162 is preferably fixed to the bottom wall 71 of the main rail 70 using fastening members such as screws. The link support 162 does not move relative to the main rail 70 even when the drive shoe 110 is driven.

Although hidden by other components in FIGS. 4 and 5, the link biasing portion 163 is compressed between the rear link 150 and the bottom wall 71 of the rail unit 60 . Therefore, the link biasing portion 163 applies elastic force to the rear link 150 according to the amount of compressive deformation. That is, the link biasing portion 163 biases the rear link 150 positioned at the tilted position in the direction in which the rear link 150 rotates from the tilted position to the standing position.

<Power transmission member 170>
As shown in FIGS. 8 to 11, the power transmission member 170 includes a check rod 180 that transmits power from the drive shoe 110 to the drive link, and a check block 190 that switches the state of engagement between the drive shoe 110 and the check rod 180. , provided.

The check rod 180 is bent such that the rear end portion is shifted in the width direction more than the other portion. In the following description, the portion of the check rod 180 extending in the front-rear direction is also referred to as a rod main body 181 and the rear end portion of the check rod 180 is also referred to as a rear shoe 182 . The check rod 180 has a block biasing portion 183 that biases the check block 190, and a first sliding shaft 184 and a second sliding shaft 185 extending in the width direction from the rear shoe 182. As shown in FIG. The check rod 180 is formed, for example, by coating a bending metal plate with a resin material.

As shown in FIGS. 8 and 9 , the rod body 181 extends linearly like the main rail 70 . When the main rail 70 is slightly curved as in this embodiment, it is preferable that the rod body 181 is similarly curved. A cross-sectional shape perpendicular to the longitudinal direction of the rod body 181 has a rectangular shape with the width direction as the lateral direction and the vertical direction as the longitudinal direction.

The block biasing portion 183 functions as a so-called plate spring. The block biasing portion 183 is located near the tip of the rod body 181 and is supported on the surface of the rod body 181 facing outward in the width direction. The block biasing portion 183 has a fixed end at its proximal end and a free end at its distal end. In other embodiments, the block biasing portion 183 may be a torsion coil spring or other springs.

As shown in FIGS. 10 and 11, the rear shoe 182 extends rearward from the rear end of the rod body 181 while bending in the width direction. In a front view of the check rod 180 from the front, the rear shoe 182 is positioned inward of the rod body 181 in the width direction.

The first sliding shaft 184 and the second sliding shaft 185 extend outward in the width direction from the rear shoe 182 . That is, each of the first sliding shaft 184 and the second sliding shaft 185 has a fixed end at the base end and a free end at the tip. The first sliding shaft 184 is positioned rearward and upward of the second sliding shaft 185 in a side view from the width direction. The outer diameter of the first slide shaft 184 is smaller than the outer diameter of the second slide shaft 185 . In this embodiment, the first sliding shaft 184 does not include rollers 186 while the second sliding shaft 185 includes rollers 186 . The roller 186 is made of elastomer such as rubber and resin. The elastic modulus of the roller 186 is preferably lower than the elastic modulus of the covering portion 152 of the rear link 150 .

As shown in FIGS. 8 and 9, the check block 190 includes a block body 191, a clamping portion 192 bent and extending from the tip of the block body 191, and an engagement shaft 193 extending from the block body 191 in the width direction. have.

A portion of the check block 190 excluding the engaging shaft 193 is formed by coating a metal plate with a resin material, for example. In a side view from the width direction, the block body 191 has an oval shape. The holding portion 192 extends inward in the width direction from the tip of the block body 191 and then extends along the block body 191 . A gap formed between the holding portion 192 and the block body 191 is slightly larger than the thickness of the tip of the check rod 180 . The engagement shaft 193 extends outward in the width direction from the intermediate portion of the block body 191 . The engagement shaft 193 has a cylindrical shape.

The base end of the block body 191 is supported by the tip of the check rod 180 via a connecting pin whose axial direction is the width direction. Thus, the check block 190 is rotatable about the axis extending in the width direction with respect to the rod body 181 . The block body 191 is urged downward by the block urging portion 183 of the check rod 180 on the inner side of the rod body 181 in the width direction. The sandwiching portion 192 sandwiches the tip portion of the check rod 180 in the width direction.

As shown in FIGS. 4 and 5 , the power transmission member 170 is housed in the first housing space 75 and the second housing space 76 of the main rail 70 . Specifically, the rod body 181 of the check rod 180 is accommodated in the third guide groove 76c. A portion of the rear shoe 182 of the check rod 180 is accommodated in the first guide groove 75a. At the rear end of the main rail 70 , since the intermediate wall 73 that separates the first accommodation space 75 and the second accommodation space 76 does not exist, the check rod straddles the first accommodation space 75 and the second accommodation space 76 . 180 rear shoes 182 are arranged.

In the check rod 180, the first sliding shaft 184 is in contact with the rear link 150 positioned at the tilted position, and the second sliding shaft 185 is positioned in front of the rear link 150 positioned at the tilted position. The first sliding shaft 184 presses the first sliding surface 156 of the rear link 150 from above. Therefore, in the states shown in FIGS. 4 and 5, the rear link 150 is restricted from rotating from the tilted position. As described above, the link biasing portion 163 of the rear support portion 140 is compressed between the bottom wall 71 of the rail unit 60 and the rear link 150 . In this respect, the first slide shaft 184 sandwiches the rear link 150 together with the link biasing portion 163 . Here, it can also be said that the link biasing portion 163 biases the rear link 150 positioned at the tilted position toward the first sliding shaft 184 .

At a position near the front end of the first accommodation space 75 , the check block 190 is adjacent to the second sliding portion 112 of the drive shoe 110 in the width direction. As shown in FIG. 8 , the tip of the engaging shaft 193 of the check block 190 is engaged with the engaging groove 117 of the drive shoe 110 . In other words, check block 190 connects drive shoe 110 and check rod 180 . Therefore, in the state shown in FIGS. 4 and 5 , when the drive shoe 110 is displaced rearward, the power transmission member 170 is displaced rearward together with the drive shoe 110 . As shown in FIG. 8, the check block 190 is urged by the block urging section 183 . Inside the rail unit 60, the engagement shaft 193 of the check block 190 is in contact with the insertion portion 83 of the inner cap 80 shown in FIG. 6 from above.

<Deflector 200>
As shown in FIG. 1, deflector 200 is a device that regulates airflow around roof opening 25 . The deflector 200 suppresses wind noise generated when the vehicle is running under the condition that the movable panel 40 is displaced to the fully open position.

As shown in FIGS. 2 and 3, the deflector 200 is supported by an arm support portion 201 fixed to the main rail 70, an arm 202 rotatably supported by the arm support portion 201, and the tip of the arm 202. and a movable frame 203 . The deflector 200 also includes an arm biasing portion 204 that biases the arm 202 , a fixed frame 205 fixed to the front panel 23 , and a screen 206 supported by the movable frame 203 and the fixed frame 205 . Among the constituent parts of the deflector 200, the arm support part 201, the arm 202 and the arm biasing part 204 are parts arranged on both sides of the roof opening 25 in the width direction.

The arm 202 has a rod shape whose longitudinal direction is perpendicular to the width direction. A proximal end portion of the arm 202 is supported by an arm support portion 201 . The rotation axis of arm 202 extends in the width direction. The upper surface of the arm 202 is a surface that slides on the pressing portion 116 of the drive shoe 110 .

The movable frame 203 and the fixed frame 205 are rod-shaped with the width direction as the longitudinal direction. The tip of the arm 202 is connected to the movable frame 203 . The connection position of the movable frame 203 with the arm 202 is not at the end of the movable frame 203 but at a position shifted inward from the end of the movable frame 203 in the width direction. In this embodiment, the length of the movable frame 203 in the longitudinal direction is longer than the widthwise interval between the two arms 202 , in other words, the widthwise interval between the two arm support portions 201 .

The screen 206 is a belt-like member made of resin or fabric that can be folded. The screen 206 is deployed in the space in front of the roof opening 25 or stored in a folded state. In other embodiments, screen 206 may be panel-like. The upper end of the screen 206 is supported by the movable frame 203 over the width direction. On the other hand, the lower end of the screen 206 is supported by the fixed frame 205 over the width direction.

As shown in FIG. 2, deflectors 200 are positioned along the front and side edges of roof opening 25 . The arm support portion 201 is fixed to the bottom wall 71 of the main rail 70 . Specifically, as shown in FIG. 3, the arm support portion 201 is fixed forward of the front end of the inner wall 72 of the main rail 70 and inward of the intermediate wall 73 of the main rail 70 in the width direction. . The arm biasing portion 204 is arranged between the arm 202 and the bottom wall 71 of the main rail 70 . The arm biasing portion 204 biases the arm 202 in the direction in which the movable frame 203 is separated from the bottom wall 71 of the main rail 70 .

As shown in FIG. 12, the arm 202 extends along the main rail 70 in plan view from above. In the state shown in FIG. 12, the arm 202 is positioned side by side with at least part of the front link 130 in the width direction. The arm 202 is positioned side by side with at least part of the rear link 150 in the front-rear direction. Also, the arm 202 and the rear link 150 are positioned inward of the front link 130 in the width direction.

As shown in FIG. 3, when the movable panel 40 is positioned at the fully closed position, the arm 202 is in contact with the pressing portion 116 of the drive shoe 110 from below. Therefore, the arm 202 is restricted from rotating in the direction in which the screen 206 is deployed according to the biasing force of the arm biasing portion 204 . In other words, screen 206 is retracted.

The sunroof device 30 of this embodiment operates the movable panel 40 by displacing the drive shoe 110 in the front-rear direction. Specifically, when the drive shoe 110 is displaced rearward, the movable panel 40 is opened, and when the drive shoe 110 is displaced forward, the movable panel 40 is closed. In the following description, the position where the movable panel 40 fully closes the roof opening 25 is called the "fully closed position", and the position where the movable panel 40 fully opens the roof opening 25 is called the "fully open position". A position where the rear end of the movable panel 40 is raised above the fully closed position is called a "tilt-up position", and a position where the front end of the movable panel 40 is above the tilt-up position is called a "lift-up position".

Further, the position of the drive shoe 110 that displaces the movable panel 40 to the fully closed position is called the "fully closed position", and the position of the drive shoe 110 that displaces the movable panel 40 to the fully open position is called the "fully opened position". The position of the drive shoe 110 that displaces the movable panel 40 to the tilt-up position is called the "tilt-up corresponding position", and the position of the drive shoe 110 that displaces the movable panel 40 to the lift-up position is called the "lift-up corresponding position". . In the movement range of the drive shoe 110, the most forward position corresponds to the fully closed position, and the most rearward position corresponds to the fully open position. The tilt-up corresponding position and the lift-up corresponding position are positions between the fully closed corresponding position and the fully open corresponding position.

<Action of sunroof device 30>
The operation of the sunroof device 30 when the movable panel 40 is opened will be described below with reference to FIGS. 13 to 25. FIG.

In the state shown in FIG. 13, the drive shoe 110 is located at the fully closed corresponding position. As shown in FIG. 14, when the drive shoe 110 is positioned at the fully closed corresponding position, the front link 130 is positioned furthest forward in the front-rear direction and is most forwardly inclined. As shown in FIG. 15, the rear link 150 is positioned at the most forward tilted position. As a result, as shown in FIG. 13 , the support bracket 100 is positioned furthest forward in the front-rear direction and is furthest lowered. Therefore, the movable panel 40 is located at the fully closed position.

As shown in FIG. 16, when the drive shoe 110 is positioned at the fully closed corresponding position, the drive shoe 110 and the check block 190 overlap in the width direction. Specifically, the engagement shaft 193 of the check block 190 is engaged with the engagement groove 117 of the drive shoe 110 . That is, the drive shoe 110 is connected with the check rod 180 via the check block 190 . In other words, check rod 180 is displaceable with drive shoe 110 .

As shown in FIG. 13 , the pressing portion 116 of the drive shoe 110 is in contact with the tip portion of the arm 202 . Therefore, the arm 202 is restricted from rising, and the screen 206 is housed between the front panel 23 and the movable panel 40 .

As shown in FIG. 17 , when the drive shoe 110 moves rearward from the fully closed corresponding position, the power of the drive shoe 110 is transmitted only to the rear link 150 of the front link 130 and the rear link 150 . That is, the posture of the rear link 150 changes without substantially changing the position and posture of the front link 130 .

As shown in FIG. 14, the first guide hole 134a of the front link 130 extends in the movement direction of the drive shoe 110. As shown in FIG. 14, when the drive shoe 110 is displaced rearward from the fully closed corresponding position, the guide shaft 115 of the drive shoe 110 moves along the first guide hole 134a of the front link 130. Displace. Therefore, the power of the drive shoe 110 is not substantially transmitted to the front link 130, and the position and posture of the front link 130 are substantially unchanged. 8 is engaged with the restricting portion 94 of the outer cap 90 shown in FIG. 6, the front link 130 is less likely to be displaced rearward.

As shown in FIG. 16, the engagement shaft 193 of the check block 190 engages the engagement groove 117 of the drive shoe 110 . Therefore, when the drive shoe 110 is displaced rearward from the fully closed corresponding position, the power transmission member 170 is displaced rearward together with the drive shoe 110 . Then, as shown in FIG. 18, the first sliding shaft 184 and the second sliding shaft 185 of the check rod 180 push the first sliding surface 155 and the second sliding surface 157 of the rear link 150 rearward. , the rear link 150 rotates from the tilted position toward the upright position. Here, the first sliding shaft 184 pushes the first sliding surface 155 rearward while sliding on the first sliding surface 155 , and the rollers 186 of the second sliding shaft 185 push the second sliding surface 157 . While rolling upward, the second sliding surface 157 is pushed backward. In this embodiment, rolling is assumed to be one aspect of sliding.

The state in which the power of drive shoe 110 is transmitted only to rear link 150 of front link 130 and rear link 150 continues until drive shoe 110 reaches the tilt-up corresponding position. That is, until the drive shoe 110 reaches the tilt-up corresponding position, the position and posture of the front link 130 do not substantially change, and the posture of the rear link 150 changes.

As shown in FIG. 17, when the drive shoe 110 is displaced rearward from the fully closed corresponding position, the pressing portion 116 of the drive shoe 110 and the arm 202 slide. As a result, the engagement relationship between the pressing portion 116 and the arm 202 changes. However, since the holding portion 116 restricts the lifting of the arm 202, the screen 206 continues to be retracted.

As shown in FIGS. 19 and 20, when the drive shoe 110 is displaced to the tilt-up corresponding position, the rear link 150 is displaced to the upright position. Therefore, when the drive shoe 110 is displaced from the fully closed corresponding position to the tilt-up corresponding position, the rear end portion of the support bracket 100 rises with respect to the front end portion thereof. As a result, the movable panel 40 is displaced to a tilt-up position where the rear end portion is raised relative to the front end portion from the fully closed position.

When the rear link 150 is displaced from the tilted position to the upright position, the sliding modes between the two sliding shafts 184 and 185 and the two sliding surfaces 155 and 157 are the following first sliding mode and second sliding mode. It changes in order of the 2nd sliding mode and the 3rd sliding mode. The first sliding mode is a state in which the first sliding shaft 184 does not slide on the first sliding surface 155 while the second sliding shaft 185 slides on the second sliding surface 157 . The second sliding mode is a state in which the first sliding shaft 184 and the second sliding shaft 185 slide on the first sliding surface 155 and the second sliding surface 157, respectively. The third sliding mode is a state in which the first sliding shaft 184 slides on the first sliding surface 155 while the second sliding shaft 185 does not slide on the second sliding surface 157 . Therefore, when the rear link 150 is displaced to the upright position as shown in FIG. away from surface 157;

As shown in FIGS. 19 and 21, when the drive shoe 110 is displaced to the tilt-up corresponding position, the manner of engagement between the drive shoe 110 and the check block 190 changes. Specifically, the engagement shaft 193 of the check block 190 is no longer engaged with the engagement groove 117 of the drive shoe 110 .

As shown in FIG. 16 , the check block 190 slides on the insertion portion 83 of the rail unit 60 when the drive shoe 110 is displaced from the fully closed corresponding position to just before the tilt-up corresponding position. In other words, the check block 190 is in contact with the insertion portion 83 of the rail unit 60 to restrict rotation based on the biasing force of the block biasing portion 183 . On the other hand, as shown in FIG. 21 , when the drive shoe 110 is displaced to the tilt-up corresponding position, the engagement recess 85 of the rail unit 60 is positioned below the engagement shaft 193 of the check block 190 . Therefore, the check block 190 rotates with respect to the check rod 180 based on the biasing force of the block biasing portion 183 . As a result, the engagement shaft 193 of the check block 190 engages with the engagement recess 85 of the rail unit 60 but does not engage with the engagement groove 117 of the drive shoe 110 . In other words, the engagement target of the check block 190 changes from the drive shoe 110 to the rail unit 60, and the check block 190 is displaced from the connected position to the disconnected position. Therefore, when the drive shoe 110 is displaced rearward after the check block 190 is displaced to the cutting position, in other words, when the drive shoe 110 is displaced rearward from the tilt-up corresponding position, the power of the drive shoe 110 is applied to the check rod. 180.

When the engagement shaft 193 of the check block 190 engages with the engagement recess 85 of the rail unit 60, the check rod 180 cannot be displaced in the front-rear direction. Therefore, the state in which the rear link 150 is displaced to the upright position is maintained. In other words, an unexpected change in the posture of rear link 150, to which power transmission from drive shoe 110 is cut off, is suppressed.

When the drive shoe 110 is displaced rearward from the tilt-up corresponding position, the power of the drive shoe 110 is transmitted only to the front link 130 of the front link 130 and the rear link 150 . That is, the posture of the front link 130 changes without changing the posture of the rear link 150 .

As indicated by the two-dot chain line in FIG. 14, when the drive shoe 110 is positioned at the tilt-up corresponding position, the guide shaft 115 of the drive shoe 110 is positioned near the end of the first guide hole 134a of the front link 130. . In other words, the guide shaft 115 of the drive shoe 110 is located near the starting end of the second guide hole 134b of the front link 130. As shown in FIG. Therefore, when the drive shoe 110 is displaced rearward from the tilt-up corresponding position, the guide shaft 115 of the drive shoe 110 slides on the wall surface of the second guide hole 134 b of the front link 130 . As a result, as shown in FIGS. 22 and 23, the front link 130 rotates about the axis of the sliding protrusion 133 so that the front end of the front link 130 rises. At this time, the reason why the front link 130 rotates without being displaced rearward is that the engagement projection 132 of the front link 130 shown in FIG. 8 is engaged with the restricting portion 94 of the outer cap 90 shown in FIG. be. The engagement between the engaging protrusion 132 of the front link 130 and the restricting portion 94 of the outer cap 90 is released by the rotation of the front link 130 .

As shown in FIGS. 22 and 23, the rotation of the front link 130 is completed when the drive shoe 110 is displaced to the lift-up corresponding position. When the front link 130 rotates, the support shaft 104 of the support bracket 100 is displaced along the second guide grooves 81b, 91b of the inner cap 80 and the outer cap 90. As shown in FIG. Therefore, the front end portion of the support bracket 100 rises relative to the rear end portion thereof. As a result, the movable panel 40 is displaced from the tilt-up position to the lift-up position where the front end is raised.

As shown in FIG. 22, when the drive shoe 110 is displaced to the lift-up corresponding position, the pressing portion 116 of the drive shoe 110 and the arm 202 slide. As a result, in the arm 202, the contact position with the pressing portion 116 changes from a position closer to the distal end to a position closer to the proximal end. Therefore, when the drive shoe 110 moves rearward in the vicinity of the lift-up corresponding position, the arm 202 gradually rotates in the direction in which the screen 206 is deployed.

When the drive shoe 110 is displaced rearward from the lift-up corresponding position, the power of the drive shoe 110 is transmitted only to the front link 130 of the front link 130 and the rear link 150 . That is, the front link 130 is displaced rearward without changing the posture of the rear link 150 .

As shown in FIGS. 24 and 25 , when the drive shoe 110 is displaced rearward from the lift-up corresponding position, the front link 130 is displaced rearward together with the drive shoe 110 . At this time, since the guide shaft 115 of the drive shoe 110 is not relatively displaced with respect to the front link 130, the attitude of the front link 130 does not change. Accordingly, as the drive shoe 110 is displaced rearward, the support bracket 100 is displaced rearward while maintaining its posture. At this time, the support shaft 104 of the support bracket 100 slides on the second guide groove 76 b of the main rail 70 , and the lower flange 103 of the support bracket 100 slides on the slider 161 .

When the drive shoe 110 is displaced rearward from the lift-up corresponding position, the pressing portion 116 of the drive shoe 110 is separated from the arm 202 . As a result, screen 206 unfolds.
As shown in FIG. 24, when the drive shoe 110 reaches the fully open corresponding position, the movable panel 40 is displaced to the fully open position. At this time, as shown in FIG. 25, the rear end portion of the drive shoe 110 and the rear end portion of the front link 130 overlap the rear support portion 140 in the width direction.

In the sunroof device 30, the opening operation of the movable panel 40 from the fully closed position to the fully open position has been described above. In the following, the operation of the sunroof device 30 when the movable panel 40 is closed will be briefly described.

When the movable panel 40 is closed from the fully open position, the drive shoe 110 is displaced forward from the fully open corresponding position. When the drive shoe 110 is displaced from the fully open corresponding position to the lift-up corresponding position, the front link 130 is displaced forward together with the drive shoe 110 . As a result, the support bracket 100 is displaced forward, and the movable panel 40 is displaced from the fully open position to the lift-up position. Before the drive shoe 110 reaches the lift-up corresponding position, the pressing portion 116 of the drive shoe 110 begins to tilt the arm 202 of the deflector 200 . Therefore, the screen 206 begins to be retracted before the drive shoe 110 reaches the lift-up corresponding position.

When the drive shoe 110 is displaced from the lift-up corresponding position to the tilt-up corresponding position, the engagement target of the guide shaft 115 of the drive shoe 110 changes from the second guide hole 134b of the front link 130 to the first guide hole 134a. do. Therefore, the front link 130 rotates so that the front end of the front link 130 descends. As a result, the tip of the support bracket 100 is lowered, and the movable panel 40 is displaced from the lift-up position to the tilt-up position.

When the drive shoe 110 is displaced forward from the tilt-up corresponding position, the engagement target of the engagement shaft 193 of the check block 190 changes from the engagement recess 85 of the rail unit 60 to the engagement groove 117 of the drive shoe 110 . In other words, check block 190 is displaced from the disconnected position to the connected position. This is because the engagement shaft 193 of the check block 190 slides on the wall surface of the engagement groove 117 of the drive shoe 110, and the check block 190 rotates against the biasing force of the block biasing portion 183. . More specifically, this is because the check block 190 rotates as the engagement shaft 193 is guided deep into the engagement groove 117 . Thus, when the drive shoe 110 is displaced forward from the tilt-up corresponding position, the drive shoe 110 is connected with the check rod 180 via the check block 190 .

Under the condition that the drive shoe 110 is connected to the check rod 180 , when the drive shoe 110 is displaced to the fully closed corresponding position, the check rod 180 is displaced forward together with the drive shoe 110 . At this time, the first sliding shaft 184 of the check rod 180 pushes the first sliding surface 156 of the rear link 150 forward, thereby displacing the rear link 150 from the upright position to the tilted position. When the movable panel 40 is closed, unlike when the movable panel 40 is opened, the first sliding shaft 184 pushes the rear link 150 forward, while the second sliding shaft 185 pushes the rear link 150 forward. do not push forward.

When the drive shoe 110 reaches the fully closed corresponding position, the rear link 150 is displaced to the tilted position. As a result, the rear end portion of the support bracket 100 descends, displacing the movable panel 40 to the fully closed position.

<Effect of Sunroof Device 30>
(1) The sunroof device 30 switches the power transmission state from the drive shoe 110 to the check rod 180 by displacing the check block 190 between the connected position and the disconnected position. In other words, the sunroof device 30 does not use the deformation of the check rod 180 to switch the power transmission state from the drive shoe 110 to the check rod 180 . Therefore, since external force is suppressed from acting on the deformed check rod 180, stress concentration on the check rod 180 and buckling of the check rod 180 are less likely to occur. Therefore, the sunroof device 30 can enhance the durability of the check rod 180. FIG.

(2) When the drive shoe 110 supports the check block 190 , the shape of the rail unit 60 must be devised so that the check block 190 displaced together with the drive shoe 110 does not interfere with the rail unit 60 . In this regard, in the sunroof device 30, the check rod 180 supports the check block 190, so the shape of the rail unit 60 can be simplified. Further, the sunroof device 30 can switch the position of the check block 190 according to the direction in which the drive shoe 110 is displaced.

(3) When the drive shoe 110 is displaced between the fully closed corresponding position and the tilt-up corresponding position, the engagement shaft 193 of the check block 190 engages the engagement groove 117 of the drive shoe 110 to The shoe 110 and the check rod 180 are connected. On the other hand, when the drive shoe 110 is displaced between the tilt-up corresponding position and the fully open corresponding position, the engagement shaft 193 of the check block 190 is engaged with the engagement concave portion 85 of the rail unit 60, thereby causing the drive shoe 110 to move. and the check rod 180 are disconnected. Thus, the engagement shaft 193 of the check block 190 functions as a portion that engages with the drive shoe 110 and also functions as a portion that engages with the rail unit 60 . Therefore, in the sunroof device 30, the structure of the check block 190 can be simplified in that the check block 190 does not need to be provided with two engaging shafts.

(4) In the sunroof device 30, the check block 190 has a sandwiching portion 192 that sandwiches the front end portion of the check rod 180 in the width direction. Therefore, when the check block 190 is displaced between the connected position and the disconnected position, the check block 190 is less likely to move in the width direction with respect to the check rod 180 . Thus, the sunroof device 30 can smoothly displace the check block 190 between the connected position and the disconnected position.

(5) When moving the movable panel 40 between the lift-up position and the fully open position, the front link 130 is displaced along the rail unit 60 . At this time, since the front link 130 and the rear link 150 are shifted in the width direction, the amount of displacement of the front link 130 in the front-rear direction can be increased. Moreover, since at least a portion of the rear link 150 and the arm 202 of the deflector 200 overlap in the width direction, the area occupied by the components of the sunroof device 30 is reduced in the width direction. Therefore, the sunroof device 30 can make the roof opening 25 wider.

(6) For example, when the four corners of the roof opening 25 are rounded in plan view in the vertical direction, the length in the width direction of the roof opening 25 may become shorter toward the rear. In this case, among the components of the sunroof device 30 , those components that operate near the rear end of the roof opening 25 are preferably arranged away from the side ends of the roof opening 25 . In this regard, in the sunroof device 30, the rear link 150 that operates behind the front link 130 is arranged inward of the front link 130 in the width direction. Therefore, the sunroof device 30 can arrange the rear link 150 further rearward while avoiding interference between the rear link 150 and the rear panel 24 or the weather strip 26 . Therefore, the amount of rearward movement of the front link 130 when opening the movable panel 40 is increased. As a result, when the movable panel 40 is displaced to the fully open position, the portion of the roof opening 25 not covered by the movable panel 40 becomes wider. Specifically, the distance in the front-rear direction between the front end of the roof opening 25 and the front end of the movable panel 40 positioned at the fully open position is increased.

(7) The sunroof device 30 can store the screen 206 by the pressing portion 116 of the drive shoe 110 . Here, since the pressing portion 116 moves along the rail unit 60, the sunroof device 30 can suppress excessive rotation of the arm 202 when the screen 206 is retracted. In other words, the sunroof device 30 can easily manage the position of the movable frame 203 when the screen 206 is retracted. In addition, when compared with the configuration in which the movable panel 40 presses the arm 202, the deflector 200 and other driving components are less likely to protrude downward. Therefore, the sunroof device 30 can be made thin in the vertical direction of the entire device.

(8) In the sunroof device 30, the shape of the covering portion 152 can be relatively freely selected in that the covering portion 152 is made of a resin material. Therefore, in the sunroof device 30 , the shape of the covering portion 152 can be made according to the empty space around the rear link 150 while providing the covering portion 152 with the sliding surfaces 155 to 157 . Thus, the sunroof device 30 can utilize the empty space around the rear link 150 .

Also, in the rear link 150 , the sliding surfaces 155 to 157 are provided on the covering portion 152 that covers the base portion 151 . Therefore, the sunroof device 30 can easily provide the sliding surfaces 155 to 157 on the rear link 150 compared to the comparative example in which the sliding surfaces 155 to 157 are provided on the base portion 151 which has a high elastic modulus and is difficult to process. In this way, the sunroof device 30 can simplify the configuration of the rear link 150 .

(9) In the rear link 150, the first sliding surfaces 155, 156 and the second sliding surface 157 are provided only on one side of the base portion 151 in the width direction. Therefore, in the sunroof device 30, compared to the comparative example in which the sliding surfaces 155 to 157 are provided on both sides of the base portion 151 in the width direction, the thickness of the rear link 150 in the width direction can be reduced.

(10) The rear link 150 compresses the link biasing portion 163 at the tilted position. In other words, the rear link 150 is sandwiched between the link biasing portion 163 and the first slide shaft 184 at the tilted position. Therefore, the rear link 150 is less likely to rattle at the tilted position. In other words, at the tilted position, the posture of the rear link 150 is easily maintained constant. Therefore, the sunroof device 30 can suppress rattling of the movable panel 40 positioned at the fully closed position.

(11) In the sunroof device 30, the two sliding shafts 184, 185 of the power transmission member 170 slide on the two sliding surfaces 155, 157 of the rear link 150, respectively. Therefore, the sunroof device 30 can smoothly displace the rear link 150 between the tilted position and the upright position. Specifically, at the beginning of raising the rear link 150 from the tilted position, the second sliding shaft 185 and the second sliding surface 157 are caused to slide. Therefore, the distance from the center of rotation of rear link 150 to the point of action of force on rear link 150 can be increased. In other words, at the beginning of raising the rear link 150 from the tilted position, the above distance can be increased compared to the comparative example in which the first sliding shaft 184 and the first sliding surface 155 slide. Therefore, the moment of the force acting on the rear link 150 is increased, and the rear link 150 can be rotated smoothly at the beginning of standing up from the tilted position.

(12) If a manufacturing error occurs in the components of the sunroof device 30, the first sliding shaft 184 and the second sliding shaft 185 slide simultaneously on the first sliding surface 155 and the second sliding surface 157, respectively. Under such circumstances, the following problems may occur. That is, when displacing the rear link 150 between the tilted position and the standing position, an overload may be applied to the rear link 150 and the power transmission member 170 . In this regard, in the check rod 180 , the second sliding shaft 185 includes a roller 186 having a smaller elastic modulus than the covering portion 152 . Therefore, the sunroof device 30 can absorb the above-described manufacturing errors by deformation of the rollers 186 .

This embodiment can be implemented with the following modifications. This embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.
- In the rail unit 60 , the main rail 70 may have a structure corresponding to the engagement recess 85 of the inner cap 80 .

- The positional relationship between the support bracket 100, the drive shoe 110, the front support portion 120, the rear support portion 140, and the power transmission member 170 can be changed as appropriate. For example, the front support portion 120 may be arranged inward in the width direction of the rear support portion 140 and the arm 202 of the deflector 200 .

- The rear link 150 may have the first sliding surfaces 155, 156 and the second sliding surface 157 on both sides in the width direction. In this case, the check rod 180 has a first sliding shaft 184 and a second sliding shaft 184 that slide on the first sliding surfaces 155, 156 and the second sliding surface 157 provided on both sides in the width direction of the rear link 150, respectively. A shaft 185 is preferably provided.

- In the rear link 150, the base 151 may have a flange that bends along the sliding surfaces 155,156. In this case, the covering portion 152 covers the flange of the base portion 151 . According to this, the rigidity of the rear link 150 can be increased.

The link biasing portion 163 may bias the rear link 150 displaced to the tilted position toward the upright position. For example, the link biasing portion 163 may be installed on the bottom wall 71 of the main rail 70 . Also, the link biasing portion 163 may be a coil spring that biases the rear link 150 around the rotation axis.

In the above embodiment, the check rod 180 supports the check block 190, and the check block 190 engages with the drive shoe 110 to connect the drive shoe 110 and the check rod 180 together. On the other hand, in a modified example, drive shoe 110 may be configured to support check block 190 . Also, the check block 190 may be configured to connect the drive shoe 110 and the check rod 180 by engaging with the check rod 180 .

- The check rod 180 may have an engagement shaft that engages with the engagement groove 117 of the drive shoe 110 and an engagement shaft that engages with the engagement recess 85 of the rail unit 60 separately.
- The check rod 180 may support the check block 190 reciprocatingly in a certain direction instead of rotatably supporting it.

- In the check rod 180 , both the first sliding shaft 184 and the second sliding shaft 185 may be provided with rollers 186 . In the check rod 180 , both the first sliding shaft 184 and the second sliding shaft 185 may not have the rollers 186 .

• The check rod 180 may have a single sliding axis. In this case, the rear link 150 preferably has a single sliding shaft and a single sliding surface.
- In the deflector 200, if the screen 206 has a certain degree of rigidity, the deflector 200 does not need to be provided with the movable frame 203. In this case, the arm 202 preferably directly supports the screen 206 at its tip.

- If the drive shoe 110 does not have the pressing portion 116 , the screen 206 may be retracted by bringing the movable panel 40 , which is to be closed, into contact with the arm 202 of the deflector 200 .

- The length of the roof opening 25 in the width direction may gradually decrease toward the rear. In other words, the roof opening 25 may have a trapezoidal shape when viewed from above. In this case, if the rear end portion of the outer wall 74 is notched like the main rail 70 of this embodiment, the main rail 70 can be arranged near the side panel 22 . As a result, the roof opening 25 can be widened.

- The sunroof device 30 may be configured such that the movable panel 40 can be operated between the tilt-up position and the fully open position without going through the lift-up position.
