Sunroof device

Abstract

The invention provides a sunroof device capable of inhibiting thickness increase in the vertical direction caused by a retainer. The power transmission member (200) has a stopper (250) that rotates about an axis extending in the longitudinal direction of the guide unit (60) between an engaged position at which power can be transmitted from the drive shoe (100) to the rear support section (150) and a released position at which power cannot be transmitted from the drive shoe (100) to the rear support section (150). The guide unit (60) has an inner sliding surface that rotates the stopper (250) from the engagement position to the release position by sliding the stopper (250) when the shoe (100) is driven rearward toward the upwarp corresponding position. The drive shoe (100) has an outer sliding surface on which the stopper (250) slides when the drive shoe (100) moves forward from the upwarp-corresponding position, thereby causing the stopper (250) to rotate from the release position to the engagement position.

Description

Technical Field

[0001] The invention relates to a skylight device. Background Art

[0002] Patent document 1 describes a vehicle equipped with a sunroof device. The sunroof device includes: a movable panel for opening and closing a roof opening, a guide rail extending in the front-rear direction, and a driving shoe moving in the front-rear direction along the guide rail. In addition, the sunroof device includes: a functional bracket fixed to the movable panel, a rear support portion supporting the functional bracket, and a stopper for switching the transmission state of power from the driving shoe to the rear support portion.

[0003] The movable panel moves between a fully closed position in which the roof opening is fully closed, a tilted position in which the rear end is raised compared to the fully closed position, and a fully open position in which the roof opening is fully opened. The functional bracket has a guide pin that slides along the guide rail at the front end. The functional bracket moves in the front-to-back direction along the guide rail based on the power transmitted from the driving slide, so that the movable panel moves between the tilted position and the fully open position. The rear support part supports the rearward part of the functional bracket compared to the guide pin. The rear support part rotates around an axis extending in the width direction based on the power transmitted from the driving slide, so that the movable panel moves between the fully closed position and the tilted position. When the movable panel moves between the fully closed position and the tilted position, the stopper transmits power from the driving slide to the rear support part, and when the movable panel moves between the tilted position and the fully open position, the stopper does not transmit power from the driving slide to the rear support part.

[0007] In the above-mentioned sunroof device, generally, the stopper switches the transmission state of the power from the driving shoe by moving in the up-down direction of the vehicle. That is, the above-mentioned sunroof device needs to ensure the moving range of the stopper in the up-down direction. In other words, the above-mentioned sunroof device still has room for improvement in terms of thinning in the up-down direction. Summary of the invention

[0008] Technical means for solving technical problems

[0009] The following describes technical means for solving the above-mentioned technical problems and their effects.

[0010] The sunroof device for solving the above technical problems comprises: a movable panel, which moves between a fully closed position, a tilted position and a fully open position, wherein the movable panel completely closes the roof opening of the vehicle in the fully closed position, the rear end of the movable panel rises compared with the fully closed position in the tilted position, the fully open position is a position closer to the rear than the tilted position, and the movable panel completely opens the roof opening in the fully open position; a guide unit, which extends in the front-to-back direction; a front support portion, which supports the movable panel; and a rear support portion, which is located at a position closer to the rear than the front support portion. The rear support of the movable panel; a driving shoe, which drives the front support part and the rear support part by moving along the guide unit; and a power transmission component, when the movable panel moves between the fully closed position and the tilted position, the power transmission component transmits power from the driving shoe to the rear support part, and when the movable panel moves between the tilted position and the fully open position, the power transmission component does not transmit power from the driving shoe to the rear support part, and when the driving shoe moves backward, the movable panel moves from the fully closed position to the fully open position via the tilted position. The movable panel is opened by the sliding movement, and when the driving shoe moves forward, the movable panel is closed from the fully open position via the tilted position to the fully closed position. The front supporting part moves the movable panel in the front-to-rear direction based on the power transmitted from the driving shoe, and the rear supporting part raises and lowers the rear end of the movable panel based on the power transmitted from the driving shoe via the power transmission component, so that the movable panel moves between the fully closed position and the tilted position. The power transmission component has a stopper, which is in an engagement position capable of transmitting power from the driving shoe to the rear supporting part. and a release position in which power cannot be transmitted from the drive shoe to the rear support portion, and when the position of the drive shoe when the movable panel is in the tilted position is set to the tilted corresponding position, at least one of the guide unit and the drive shoe has a sliding surface, and when the drive shoe moves rearward toward the tilted corresponding position or when the drive shoe moves forward from the tilted corresponding position, the sliding surface allows the stopper to slide, so that the stopper rotates from one of the engaged position and the released position toward the other position.

[0011] The sunroof device is provided with a stopper for switching the transmission of power from the driving shoe to the rear support. The stopper rotates between an engaged position and a released position. In the engaged position, power can be transmitted from the driving shoe to the rear support, and in the released position, power cannot be transmitted from the driving shoe to the rear support. That is, by the fact that the stopper does not move greatly in the up-down direction between the engaged position and the released position, the sunroof device can suppress the increase in thickness in the up-down direction. In addition, when the driving shoe moves rearward toward the corresponding position of the tilting, the stopper rotates to the released position by sliding along the sliding surface. Alternatively, when the driving shoe moves forward from the corresponding position of the tilting, the stopper rotates to the engaged position by sliding along the sliding surface. Therefore, the sunroof device can switch the position of the stopper according to the movement of the driving shoe.

[0012] Effects of the Invention

[0013] The sunroof device can suppress an increase in thickness in the up-down direction caused by the stopper. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0053] Hereinafter, one embodiment of the sunroof device will be described.

[0054] <Structure of this embodiment>

[0055] like Figure 1 As shown, the vehicle 10 includes a vehicle body 20 and a sunroof device 30. In the drawings, the extending direction of the X-axis indicates the width direction of the vehicle 10, the extending direction of the Y-axis indicates the front-rear direction of the vehicle 10, and the extending direction of the Z-axis indicates the up-down direction of the vehicle 10. In the following description, the width direction of the vehicle 10, the front-rear direction of the vehicle 10, and the up-down direction of the vehicle 10 are also referred to as the width direction, the front-rear direction, and the up-down direction, respectively. In addition, the direction away from the center of the vehicle 10 in the width direction is also referred to as the outside, and the direction close to the center of the vehicle 10 in the width direction is also referred to as the inside.

[0056] <Body 20>

[0057] like Figure 2 As shown in FIG. 1 , the vehicle body 20 includes a roof structure 21 constituting a roof. The roof structure 21 includes two side panels 22 extending in the front-rear direction, a front panel 23 connecting the front ends of the two side panels 22, and a rear panel 24 connecting the rear ends of the two side panels 22. In addition, the roof structure 21 includes a roof opening 25 divided by the two side panels 22, the front panel 23, and the rear panel 24. In a top view viewed from above, the roof opening 25 is rectangular in shape with the width direction as the long side direction and the front-rear direction as the short side direction.

[0058] <Skylight device 30>

[0059] like Figure 2 As shown, the sunroof device 30 includes a movable panel 40, an actuator 50, two guide units 60, two drive shoes 100, two front support parts 110, two rear support parts 150, and two power transmission members 200. Most of the components of the sunroof device 30 are symmetrical in shape and are arranged on the right and left sides of the roof opening 25. Therefore, in the following description, the components on the right side of the sunroof device 30 are described with respect to the components that are symmetrical in shape.

[0060] <Movable panel 40>

[0061] like Figure 2 As shown, the movable panel 40 includes a panel body 41 , two front brackets 42 , and two rear brackets 43 .

[0062] The panel body 41 is made of a light-transmitting material such as glass or resin. The panel body 41 has a size and shape corresponding to the roof opening 25. The two front brackets 42 are located in front of the two rear brackets 43. The two front brackets 42 are located on both sides of the width direction of the panel body 41. Similarly, the two rear brackets 43 are located on both sides of the width direction of the panel body 41. The two front brackets 42 and the two rear brackets 43 are joined to the lower surface of the panel body 41.

[0063] <Actuator 50>

[0064] The actuator 50 includes a motor 51, two cables 52 driven by the motor 51, and a conversion mechanism 53 that converts the rotational motion of the output shaft of the motor 51 into the forward and backward motion of the cables 52. The motor 51 and the conversion mechanism 53 are fixed to the center portion in the width direction of the front panel 23. The cables 52 are push-pull cables that can push and pull the sliding shoe 100. The cables 52 are arranged along the front panel 23 and the guide unit 60.

[0065] <Guide unit 60>

[0066] like Figure 3 to Figure 5 As shown, the guide unit 60 includes a guide rail 70 , an inner front guide 80 , and an outer front guide 90 .

[0067] The guide rail 70 has a front-to-back direction as a long side direction. In a side view in the width direction, the guide rail 70 is curved in such a way that the central portion in the long side direction is located above the two end portions in the long side direction. In the present embodiment, the guide rail 70 extending in the front-to-back direction includes a guide rail 70 extending in a curved manner in addition to a guide rail 70 extending in a straight line.

[0068] In the following description, the long side direction of the guide rail 70 is referred to as the "first reference direction", and the direction orthogonal to the first reference direction and the width direction is referred to as the "second reference direction". When the guide rail 70 is bent, the tangent direction of the guide rail 70 is equivalent to the first reference direction, and the normal direction of the guide rail 70 is equivalent to the second reference direction. That is, when the guide rail 70 is bent, the first reference direction and the second reference direction are oriented in different directions depending on the position of the guide rail 70. The guide rail 70 is formed by extruding a metal material such as an aluminum alloy, for example.

[0069] like Figure 5As shown, the guide rail 70 includes a bottom wall 71, an inner wall 72, and an outer wall 73. The bottom wall 71 is a flat plate having a first reference direction as a long side direction and a width direction as a short side direction. The inner wall 72 extends from a position closer to the inner end than the outer end in the width direction of the bottom wall 71. The inner wall 72 includes a first inner wall 72a extending upward from the bottom wall 71, a second inner wall 72b extending from the top end of the first inner wall 72a to the outer side in the width direction, and a third inner wall 72c extending from the first inner wall 72a to the outer side in the width direction below the second inner wall 72b. The outer wall 73 extends from a position closer to the outer end than the inner end in the width direction of the bottom wall 71. The outer wall 73 has: a first outer wall 73a extending upward from the bottom wall 71, a second outer wall 73b extending inward in the width direction from the top end of the first outer wall 73a, and a third outer wall 73c extending inward in the width direction from the first outer wall 73a below the second outer wall 73b.

[0070] like Figure 5 and Figure 6 As shown, the inner front guide 80 has an extension portion 81 constituting the front end portion of the guide unit 60, an insertion portion 82 inserted into the guide rail 70, and a connection portion 83 connected to the outer front guide 90. The extension portion 81 has a guide groove 84 extending upward as it moves backward. The guide groove 84 has a width direction as a depth direction.

[0071] like Figure 6 As shown, the insertion portion 82 extends rearward from the extension portion 81. The insertion portion 82 has a side wall 85 with the width direction as the plate thickness direction, and a first inner engaging wall 86 and a second inner engaging wall 87 protruding outward in the width direction from the side wall 85. The surface of the side wall 85 facing outward in the width direction is a curved surface 85a convex in the same direction.

[0072] In the first reference direction, the length of the first inner engaging wall 86 is smaller than the length of the side wall 85. The front end of the first inner engaging wall 86 is flush with the front end of the side wall 85. On the other hand, the rear end of the first inner engaging wall 86 is located forward compared to the rear end of the side wall 85. The lower end of the first inner engaging wall 86 is located above the lower end of the side wall 85.

[0073] The first inner engaging wall 86 has an inner limiting surface 86a, an inner auxiliary sliding surface 86b and an inner clamping surface 86c that intersect with the protruding direction protruding relative to the side wall 85. The inner limiting surface 86a is a surface that intersects with the second reference direction and is a surface along the first reference direction. The inner auxiliary sliding surface 86b intersects with both the first reference direction and the second reference direction. In detail, the inner auxiliary sliding surface 86b is inclined in an upward direction as it advances backward. The front end of the inner auxiliary sliding surface 86b is connected to the rear end of the inner limiting surface 86a. The inner clamping surface 86c extends along the second reference direction. The inner clamping surface 86 preferably intersects with the first reference direction at an angle close to a right angle. The lower end of the inner clamping surface 86c is connected to the rear end of the inner auxiliary sliding surface 86b.

[0074] The second inner engaging wall 87 protrudes from the rear end of the side wall 85. The second inner engaging wall 87 is located rearward compared to the first inner engaging wall 86. The second inner engaging wall 87 has an inner sliding surface 87a and an inner clamping surface 87b that intersect with the protruding direction relative to the side wall 85. The inner sliding surface 87a intersects with both the first reference direction and the second reference direction. In detail, the inner sliding surface 87a is inclined in an upward manner as it advances backward. The inner clamping surface 87b extends along the second reference direction. The inner clamping surface 87b preferably intersects with the first reference direction at an angle close to a right angle. The lower end of the inner clamping surface 87b is connected to the rear end of the inner sliding surface 87a.

[0075] The inner auxiliary sliding surface 86b of the first inner engaging wall 86 is opposite to the inner sliding surface 87a of the second inner engaging wall 87. Similarly, the inner clamping surface 86c of the first inner engaging wall 86 is opposite to the inner clamping surface 87b of the second inner engaging wall 87. The first inner engaging wall 86 is equivalent to the "second restricting portion", the inner auxiliary sliding surface 86b is equivalent to the "second auxiliary sliding surface", and the inner clamping surface 86c is equivalent to the "clamping portion". The inner sliding surface 87a is equivalent to the "sliding surface" and the "first sliding surface", and the inner clamping surface 87b is equivalent to the "clamping portion".

[0076] like Figure 5 As shown, the outer front guide 90 has an extension portion 91 constituting the front end portion of the guide unit 60, an insertion portion 92 inserted into the guide rail 70, and a connection portion 93 connected to the inner front guide 80. The extension portion 91 has a guide groove 94 extending upward as it moves backward. The guide groove 94 has a width direction as a depth direction. In the first reference direction, the length of the insertion portion 92 is much shorter than the length of the insertion portion 82 of the inner front guide 80.

[0077] like Figure 4 and Figure 5As shown, the connecting portion 83 of the inner front guide member 80 and the connecting portion 93 of the outer front guide member 90 are connected by a fastening member such as a screw or a bolt. Therefore, the inner front guide member 80 and the outer front guide member 90 are integrated. The insertion portion 82 of the inner front guide member 80 and the insertion portion 92 of the outer front guide member 90 are inserted into the top end portion of the guide rail 70. In this way, the guide groove 84 of the inner front guide member 80 is connected to the space between the second inner wall 72b and the third inner wall 72c of the guide rail 70. On the other hand, the guide groove 94 of the outer front guide member 90 is connected to the space between the second outer wall 73b and the third outer wall 73c of the guide rail 70.

[0078] like Figure 2 As shown, the guide unit 60 is fixed to the vehicle body 20 so as to be adjacent to the side panel 22. Thus, the guide unit 60 extends in the front-rear direction on both sides of the roof opening 25 in the width direction.

[0079] <Drive shoe 100>

[0080] like Figure 7 to Figure 9 As shown, the drive shoe 100 includes a bottom portion 101 , a first side wall 102 and a second side wall 103 , a first sliding portion 104 , a second sliding portion 105 , an outer engaging wall 106 , a first sliding shaft 107 , and a second sliding shaft 108 .

[0081] The bottom 101 is in a plate shape with the second reference direction being the plate thickness direction. The first side wall 102 and the second side wall 103 extend upward from the bottom 101. The first side wall 102 is located on the inner side in the width direction compared to the second side wall 103. In the width direction, the first side wall 102 is thinner than the second side wall 103, and in the first reference direction, the first side wall 102 is longer than the second side wall 103. The first sliding portion 104 extends from the upper end of the first side wall 102 to the inner side in the width direction. The second sliding portion 105 extends from the upper end of the second side wall 103 to the outer side in the width direction.

[0082] like Fig. 9 and Fig.10 As shown in FIG. 1 , the outer engaging wall 106 protrudes from the rear end of the first side wall 102 toward the inner side in the width direction. Fig.10 As shown, the outer engaging wall 106 has: a contact surface 106a, a retreat surface 106b, a first outer limiting surface 106c, an outer auxiliary sliding surface 106d, a first pressing surface 106e, a second outer limiting surface 106f, a third outer limiting surface 106g, a second pressing surface 106h and an outer sliding surface 106i.

[0083] The contact surface 106a is the front end surface of the outer engaging wall 106. The contact surface 106a extends along the second reference direction. The contact surface 106a preferably intersects the first reference direction at an angle close to a right angle. The retreat surface 106b intersects both the first reference direction and the second reference direction. In detail, the retreat surface 106b is inclined downward as it moves backward. The front end of the retreat surface 106b is connected to the lower end of the contact surface 106a. The first outer limiting surface 106c extends along the first reference direction. The front end of the first outer limiting surface 106c is connected to the rear end of the retreat surface 106b.

[0084] The outer auxiliary sliding surface 106d intersects with both the first reference direction and the second reference direction. In detail, the outer auxiliary sliding surface 106d is inclined in a manner that it is directed upward as it is advanced backward. The front end of the outer auxiliary sliding surface 106d is connected to the rear end of the first outer limiting surface 106c. The first pressing surface 106e extends along the second reference direction. The first pressing surface 106e preferably intersects with the first reference direction at an angle close to a right angle. The lower end of the first pressing surface 106e is connected to the rear end of the outer auxiliary sliding surface 106d. The second outer limiting surface 106f intersects with both the first reference direction and the second reference direction. In detail, the second outer limiting surface 106f is inclined in a manner that it is directed upward as it is advanced backward. The front end of the second outer limiting surface 106f is connected to the upper end of the first pressing surface 106e.

[0085] The third outer limiting surface 106g extends along the first reference direction. The third outer limiting surface 106g preferably intersects with the second reference direction at an angle close to a right angle. The front end of the third outer limiting surface 106g is connected to the rear end of the second outer limiting surface 106f. The second pressing surface 106h extends along the second reference direction. The second pressing surface 106h preferably intersects with the first reference direction at an angle close to a right angle. The upper end of the second pressing surface 106h is connected to the rear end of the third outer limiting surface 106g. The outer sliding surface 106i intersects with both the first reference direction and the second reference direction. In detail, the outer sliding surface 106i is inclined in a manner downward as it advances forward. The rear end of the outer sliding surface 106i is connected to the lower end of the second pressing surface 106h. The front end of the outer sliding surface 106i is located below the first outer limiting surface 106c.

[0086] In the outer engaging wall 106, the first outer restricting surface 106c corresponds to the "first rear restricting surface", the outer auxiliary sliding surface 106d corresponds to the "first auxiliary sliding surface", and the outer sliding surface 106i corresponds to the "sliding surface" and the "second sliding surface".

[0087] like Figure 8As shown, the first sliding shaft 107 protrudes outward from the first side wall 102 in the width direction. The cross-sectional shape of the first sliding shaft 107 perpendicular to the protruding direction is circular. The second sliding shaft 108 protrudes inward from the second side wall 103 in the width direction. The second sliding shaft 108 is located rearward of the first sliding shaft 107. The cross-sectional shape of the second sliding shaft 108 perpendicular to the protruding direction is rectangular.

[0088] like Figure 3 and Figure 4 As shown, the driving shoe 100 is accommodated in the guide rail 70. At this time, the bottom 101 of the driving shoe 100 is located above the bottom wall 71 of the guide rail 70. The first sliding portion 104 of the driving shoe 100 is accommodated between the second inner wall 72b and the third inner wall 72c of the guide rail 70 in the up-down direction. The second sliding portion 105 of the driving shoe 100 is accommodated between the second outer wall 73b and the third outer wall 73c of the guide rail 70 in the up-down direction. In addition, the driving shoe 100 is sandwiched by the first inner wall 72a and the first outer wall 73a of the guide rail 70 in the width direction. In this way, the driving shoe 100 is restricted by the guide rail 70 to move in a direction orthogonal to the long side direction. On the other hand, the driving shoe 100 can move relative to the guide rail 70 along the long side direction of the guide rail 70. In addition, the cable 52 of the actuator 50 is connected to the first sliding portion 104 of the driving shoe 100.

[0089] <Front support part 110>

[0090] like Figure 7 to Figure 9 As shown, the front support portion 110 includes a first front link 120 , a second front link 130 , and a bracket holding portion 140 .

[0091] The first front link 120 is in the shape of an elongated plate. The first front link 120 includes: a first guide shaft 121 and a swing shaft portion 122 with the width direction as the axial direction, and a first sliding groove 123 and a second sliding groove 124 with the width direction as the depth direction. The first guide shaft 121 is located at the front end of the first front link 120. The swing shaft portion 122 is located at the rear end of the first front link 120. The first sliding groove 123 is provided on the inner side of the first front link 120 in the width direction.

[0094] like Figure 3 and Figure 4 As shown, the front support portion 110 is accommodated in the guide unit 60. At this time, the first guide shaft 121 of the first front link 120 is inserted into the guide groove 84 of the inner front guide member 80. On the other hand, the second guide shaft 131 and the third guide shaft 132 of the second front link 130 are inserted into the guide groove 94 of the outer front guide member 90. In addition, the first front link 120 is located between the first sliding portion 104 and the second sliding portion 105 of the driving shoe 100 in the width direction. Moreover, the first sliding shaft 107 of the driving shoe 100 is inserted into the first sliding groove 123 of the first front link 120, and the second sliding shaft 108 of the driving shoe 100 is inserted into the second sliding groove 124 of the first front link 120. In addition, the swing shaft portion 122 of the first front link 120 is located between the bottom wall 71 and the second outer wall 73b of the guide rail 70 in the up-down direction. In addition, the front bracket 42 of the movable panel 40 is fixed to the bracket holding portion 140. In this regard, the front support portion 110 supports the front end portion of the movable panel 40 .

[0095] <Rear Support 150>

[0096] like Figure 11 to Figure 13 As shown, the rear support portion 150 includes a first rear link 160 , a second rear link 170 , and a rear link support portion 180 .

[0097] like Fig.12 and Fig.13As shown, the first rear link 160 is rod-shaped. The first rear link 160 has a third sliding groove 161 and a fourth sliding groove 162 with the width direction as the depth direction. The third sliding groove 161 is provided on the inner side in the width direction of the first rear link 160. The fourth sliding groove 162 is provided on the outer side in the width direction of the first rear link 160. The third sliding groove 161 and the fourth sliding groove 162 extend in a manner along the long side direction of the first rear link 160.

[0098] like Fig.12 and Fig.13 As shown, the second rear link 170 is rod-shaped. The cross-sectional shape of the second rear link 170 perpendicular to the longitudinal direction is U-shaped. The second rear link 170 has two connecting shafts 171 with the width direction as the axial direction, a fourth sliding shaft 172, and two fourth guide shafts 173. The two connecting shafts 171 are located at the top end of the second rear link 170. The fourth sliding shaft 172 is located at the center of the second rear link 170 in the longitudinal direction. The two fourth guide shafts 173 are located at the rear end of the second rear link 170.

[0099] like Fig.12 and Fig.13 As shown, the base end of the first rear link 160 is rotatably supported by the rear link support portion 180. In this way, the first rear link 160 can rotate around an axis extending in the width direction. The fourth sliding shaft 172 of the second rear link 170 is inserted into the fourth sliding groove 162 of the first rear link 160.

[0100] like Fig.11 As shown, the rear support portion 150 is accommodated in the guide rail 70. In detail, the first rear link 160 and the second rear link 170 are located between the inner wall 72 and the outer wall 73 of the guide rail 70. In addition, the rear link support portion 180 is fixed to the rear end portion of the guide rail 70. In addition, the two fourth guide shafts 173 of the second rear link 170 support the rear bracket 43 of the movable panel 40 so as to be slidable. In this regard, the rear support portion 150 supports the movable panel 40 at the rear side compared with the front support portion 110.

[0101] <Power transmission member 200>

[0102] like Figure 7 to Figure 9 , Fig.12 and Fig.13 As shown, the power transmission member 200 includes a stopper lever 210 , a stopper 250 , a rotation restricting portion 260 , a retaining ring 271 , a biasing member 272 , and a cover 273 .

[0103] The stopper lever 210 includes a lever body 220 , an extension shaft 230 , and a rear shoe 240 .

[0104] like Figure 7 to Figure 9As shown in FIG. 1 , the rod body 220 is in the shape of a rod with the first reference direction as the longitudinal direction. The rod body 220 is curved in the same manner as the guide rail 70. Fig.14 and Fig.15 As shown, the extension shaft 230 extends from the top end of the rod body 220 along the first reference direction. The extension shaft 230 has: a first shaft portion 231 in a cylindrical shape, a second shaft portion 232 in a polygonal column shape, and a flange 233 that divides the first shaft portion 231 and the second shaft portion 232. The first shaft portion 231 extends rearward from the flange 233, and the second shaft portion 232 extends forward from the flange 233. In this embodiment, the cross-sectional shape of the second shaft portion 232 is a hexagonal shape. The flange 233 is in the shape of a circular plate. The outer diameter of the first shaft portion 231 and the outer diameter of the second shaft portion 232 are smaller than the outer diameter of the flange 233.

[0105] like Fig.12 and Fig.13 As shown, the rear sliding shoe 240 is connected to the rear end of the rod body 220. The rear sliding shoe 240 includes: a first sliding portion 241 and a second sliding portion 242 positioned at intervals in the width direction, a retaining wall 243 extending upward from the first sliding portion 241, and a third sliding shaft 244 extending in the width direction from the retaining wall 243. The first sliding portion 241 is located on the inner side of the second sliding portion 242 in the width direction. The first sliding portion 241 includes an engaging recess 245 recessed upward from the bottom surface of the first sliding portion 241. Similarly, the second sliding portion 242 includes an engaging recess 245 recessed upward from the bottom surface of the second sliding portion 242.

[0106] like Fig.14 and Fig.15 As shown, the stopper 250 is a columnar member with the first reference direction as the axial direction. The stopper 250 includes: a cylindrical base 251, an inner protrusion 252 and an outer protrusion 253 protruding from the base 251 in a direction orthogonal to the axial direction of the base 251. The base 251 includes a support hole 254 penetrating in the axial direction. The cross-sectional shape of the support hole 254 is a circle.

[0107] like Fig.14 As shown, the inner protrusion 252 tapers in the protruding direction from the base 251. The inner protrusion 252 has an inner front surface 252a, an inner rear surface 252b, an inner upper surface 252c, an inner lower surface 252d, and an inner cam surface 252e.

[0108] The inner front surface 252a is the front end surface of the inner protrusion 252, and is a surface intersecting the first reference direction. The inner front surface 252a preferably intersects the first reference direction at an angle close to a right angle. The inner front surface 252a is located slightly behind the front end surface of the base 251. The inner rear surface 252b is the rear end surface of the inner protrusion 252, and is a surface intersecting the first reference direction. The inner rear surface 252b preferably intersects the first reference direction at an angle close to a right angle. The inner rear surface 252b is located slightly ahead of the rear end surface of the base 251.

[0109] The inner upper surface 252c is the upper surface of the inner protrusion 252 and is a surface along the first reference direction. The front end of the inner upper surface 252c is connected to the upper end of the inner front surface 252a, and the rear end of the inner upper surface 252c is connected to the upper end of the inner rear surface 252b. The inner lower surface 252d is the lower surface of the inner protrusion 252 and is a surface along the first reference direction. The front end of the inner lower surface 252d is connected to the lower end of the inner front surface 252a. The inner cam surface 252e intersects both the first reference direction and the second reference direction. In other words, the inner cam surface 252e is inclined in a manner that it moves toward the upper side as it moves backward. The front end of the inner cam surface 252e is connected to the rear end of the inner lower surface 252d, and the rear end of the inner cam surface 252e is connected to the lower end of the inner rear surface 252b.

[0110] like Fig.15 As shown, the outer protrusion 253 tapers in the protruding direction from the base 251. The outer protrusion 253 has an outer front surface 253a, an outer rear surface 253b, an outer upper surface 253c, an outer lower surface 253d, a first outer cam surface 253e, and a second outer cam surface 253f.

[0111] The outer front surface 253a is the front end surface of the outer protrusion 253, and is a surface intersecting the first reference direction. The outer front surface 253a preferably intersects the first reference direction at an angle close to a right angle. The outer rear surface 253b is the rear end surface of the outer protrusion 253, and is a surface intersecting the first reference direction. The outer rear surface 253b preferably intersects the first reference direction at an angle close to a right angle. The outer upper surface 253c is the upper surface of the outer protrusion 253, and is a surface along the first reference direction. The rear end of the outer upper surface 253c is connected to the upper end of the outer rear surface 253b. The outer lower surface 253d is the lower surface of the outer protrusion 253, and is a surface along the first reference direction. The front end of the outer lower surface 253d is connected to the lower end of the outer front surface 253a.

[0112] The first outer cam surface 253e intersects with both the first reference direction and the second reference direction. In other words, the first outer cam surface 253e is inclined in a manner that it is moved toward the upper side as it moves toward the rear. The front end of the first outer cam surface 253e is connected to the rear end of the outer lower surface 253d, and the rear end of the first outer cam surface 253e is connected to the lower end of the outer rear surface 253b. The second outer cam surface 253f intersects with both the first reference direction and the second reference direction. In other words, the second outer cam surface 253f is inclined in a manner that it is moved toward the upper side as it moves toward the rear. The front end of the second outer cam surface 253f is connected to the upper end of the outer front surface 253a, and the rear end of the second outer cam surface 253f is connected to the front end of the outer upper surface 253c.

[0113] The first shaft portion 231 of the extension shaft 230 is inserted into the support hole 254 of the stopper 250. In this way, the stopper 250 can rotate relative to the extension shaft 230. On the other hand, the stopper 250 is clamped by the flange 233 and the retaining ring 271 in the axial direction of the extension shaft 230. Therefore, the stopper 250 cannot move in the axial direction of the extension shaft 230.

[0114] like Fig.14 and Fig.15 As shown, the rotation limiting portion 260 includes: a cylindrical base portion 261 and a pressing portion 262 extending rearward from the base portion 261. The base portion 261 includes a sliding hole 263 penetrating in the axial direction. The cross-sectional shape of the sliding hole 263 corresponds to the cross-sectional shape of the second shaft portion 232 of the extension shaft 230. That is, the cross-sectional shape of the sliding hole 263 is a hexagonal shape. The pressing portion 262 is plate-shaped. The pressing portion 262 has a pressing surface 262a facing the axis of the sliding hole 263. The pressing surface 262a has a shape corresponding to the outer upper surface 253c of the stopper 250. The second shaft portion 232 of the extension shaft 230 is inserted into the sliding hole 263 of the rotation limiting portion 260. In this way, the rotation limiting portion 260 cannot rotate relative to the extension shaft 230. On the other hand, the rotation limiting portion 260 can move along the axial direction of the extension shaft 230. In addition, as long as the base 261 cannot rotate relative to the second shaft portion 232 of the extension shaft 230, the cross-sectional shape of the sliding hole 263 and the cross-sectional shape of the second shaft portion 232 can be appropriately changed. For example, the cross-sectional shape of the sliding hole 263 and the cross-sectional shape of the second shaft portion 232 can also be circular. The rotation limiting portion 260 is equivalent to the "first limiting portion", and the pressing surface 262a is equivalent to the "first front limiting surface".

[0115] The cover 273 has the same shape as the base 261 of the rotation limiting portion 260. The cover 273 is fixed to the front end of the extension shaft 230. The force applying member 272 is a coil spring. The second shaft portion 232 of the extension shaft 230 is inserted into the force applying member 272. The force applying member 272 is compressed between the cover 273 and the rotation limiting portion 260. In this way, the force applying member 272 applies force to the rotation limiting portion 260 toward the flange 233. That is, the restoring force of the force applying member 272 always acts on the rotation limiting portion 260.

[0116] like Figure 4 and Fig.11 As shown, the power transmission component 200 is accommodated in the guide rail 70. At this time, the portion of the power transmission component 200 except the rear shoe 240 is located between the bottom wall 71 and the second inner wall 72b of the guide rail 70 in the up-down direction. The rear shoe 240 of the power transmission component 200 is located between the inner wall 72 and the outer wall 73 in the width direction. In addition, in the up-down direction, the first sliding portion 241 of the rear shoe 240 is located between the bottom wall 71 and the inner wall 72 of the guide rail 70, and the second sliding portion 242 of the rear shoe 240 is located between the bottom wall 71 and the outer wall 73 of the guide rail 70. In this way, the movement of the power transmission component 200 relative to the guide rail 70 in the width direction and the up-down direction is restricted. On the other hand, the power transmission component 200 can move in the front-back direction along the guide rail 70.

[0117] like Figure 4 As shown in FIG. 1 , the stopper 250 of the power transmission component 200 is engaged with the outer engaging wall 106 of the driving shoe 100. In this way, the power transmission component 200 can transmit power from the outer engaging wall 106 of the driving shoe 100 via the stopper 250. Fig.12 and Fig.13 As shown, the rear shoe 240 of the power transmission component 200 engages with the first rear link 160 and the second rear link 170 of the rear support 150. In detail, the third sliding shaft 244 of the rear shoe 240 is inserted into the third sliding groove 161 of the first rear link 160. The two connecting shafts 171 of the second rear link 170 are respectively inserted into the two engaging recesses 245 of the rear shoe 240. In this way, the rear shoe 240 of the power transmission component 200 can transmit power to the first rear link 160 and the second rear link 170 via the two connecting shafts 171 and the third sliding shaft 244. In other words, the power is indirectly transmitted from the driving shoe 100 to the rear support 150 via the power transmission component 200. On the other hand, the power is directly transmitted from the driving shoe 100 to the front support 110 without passing through the power transmission component 200.

[0118] <Function of this embodiment>

[0119] The operation of the sunroof device 30 will be described.

[0120] The operation of the sunroof device 30 when the movable panel 40 is opened will be described.

[0121] Fig.16 FIG. 4 shows the sunroof device 30 when the movable panel 40 is in the fully closed position. Fig.16 In the state shown, the driving shoe 100 is located at the fully closed corresponding position at the frontmost in the range of movement in the front-back direction. When the driving shoe 100 is located at the fully closed corresponding position, the first front link 120 and the second front link 130 are located at the frontmost in the range of movement in the front-back direction, and are laid down along the guide rail 70. In addition, when the driving shoe 100 is located at the fully closed corresponding position, the power transmission component 200 is located at the frontmost in the range of movement in the front-back direction. Moreover, when the power transmission component 200 is located at the frontmost in the range of movement in the front-back direction, the first rear link 160 and the second rear link 170 are laid down in a manner along the guide rail 70.

[0122] According to the above, when the driving shoe 100 is located at the fully closed corresponding position, the front end of the movable panel 40 supported by the first front link 120 is lowered by the first front link 120 falling down. In addition, the rear end of the movable panel 40 supported by the second rear link 170 is lowered by the second rear link 170 falling down. Moreover, the first front link 120 is located at the frontmost position in its moving range, and the movable panel 40 is also located at the frontmost position in its moving range. As a result, the movable panel 40 is located at the fully closed position.

[0123] When the movable panel 40 is opened from the fully closed position, the actuator 50 moves the driving shoe 100 backward. When the driving shoe 100 moves backward from the fully closed corresponding position, the first sliding shaft 107 and the second sliding shaft 108 of the driving shoe 100 move along the first sliding groove 123 and the second sliding groove 124 of the first front link 120 in the front support 110. Therefore, when the driving shoe 100 moves backward from the fully closed corresponding position, the first front link 120 hardly moves.

[0124] When the driving shoe 100 is located at the fully closed corresponding position, the driving shoe 100 is engaged with the stopper 250 of the power transmission member 200. Therefore, when the driving shoe 100 moves backward from the fully closed corresponding position, the power transmission member 200 and the driving shoe 100 move backward together. When the power transmission member 200 moves backward, in the rear support 150, the third sliding shaft 244 of the stopper lever 210 slides along the third sliding groove 161 of the first rear link 160. Then, the first rear link 160 stands up relative to the guide rail 70.

[0125] In addition, when the power transmission member 200 moves backward, the rear shoe 240 pushes the two connecting shafts 171 of the second rear link 170 backward, and the fourth sliding shaft 172 of the second rear link 170 slides along the fourth sliding groove 162 of the first rear link 160. As a result, the second rear link 170 stands up relative to the guide rail 70. According to the above, when the driving shoe 100 moves backward from the fully closed corresponding position, the first rear link 160 and the second rear link 170 stand up. Therefore, the rear end of the movable panel 40 supported by the two fourth guide shafts 173 of the second rear link 170 rises.

[0126] When the driving shoe 100 reaches Fig.17 When the driving shoe 100 reaches the tilting corresponding position, the first rear link 160 and the second rear link 170 are in the most upright state relative to the guide rail 70. As a result, the movable panel 40 is arranged in the tilting position in which the rear end portion is raised compared to the fully closed position. When the driving shoe 100 reaches the tilting corresponding position, the engagement between the driving shoe 100 and the stopper 250 of the power transmission component 200 is released. Therefore, when the driving shoe 100 moves backward from the tilting corresponding position, the power of the driving shoe 100 is not transmitted to the rear support portion 150 via the power transmission component 200. Therefore, the posture of the first rear link 160 and the second rear link 170 does not change.

[0127] When the driving shoe 100 reaches the tilting corresponding position, the first sliding shaft 107 of the driving shoe 100 reaches near the rear end of the first sliding groove 123 of the first front link 120 in the front support portion 110. Similarly, the second sliding shaft 108 of the driving shoe 100 reaches near the rear end of the second sliding groove 124 of the first front link 120. Therefore, when the driving shoe 100 moves backward from the tilting corresponding position, the driving shoe 100 pulls the first front link 120 backward, thereby the first front link 120 moves backward.

[0128] At this time, the first guide shaft 121 of the first front link 120 moves rearward along the guide groove 84 of the inner front guide member 80, and the second guide shaft 131 of the second front link 130 moves rearward along the guide groove 94 of the outer front guide member 90. Further, the third guide shaft 132 of the second front link 130 moves rearward along the guide rail 70. As a result, the first front link 120 rotates around the swing shaft portion 122, and the front end portion of the second front link 130 rises relative to the rear end portion. As a result, the first front link 120 and the second front link 130 stand up relative to the guide rail 70. Therefore, the front end portion of the movable panel 40 supported by the first front link 120 rises via the bracket holding portion 140.

[0129] When the driving shoe 100 reaches Fig.18When the first front link 120 and the second front link 130 are in the raised corresponding position shown in the figure, the first front link 120 and the second front link 130 are in the most upright state relative to the guide rail 70. As a result, the movable panel 40 is arranged in the raised position where the front end portion is raised compared to the tilted position. When the driving shoe 100 moves backward from the raised position, the first guide shaft 121 and the swing shaft portion 122 of the first front link 120 move backward along the guide rail 70. Similarly, the second guide shaft 131 and the third guide shaft 132 of the second front link 130 move backward along the guide rail 70. That is, the first front link 120 and the second front link 130 move backward while maintaining their posture. Therefore, the movable panel 40 also moves backward while maintaining their posture. At this time, the rear bracket 43 of the movable panel 40 slides along the two fourth guide shafts 173 of the second rear link 170. That is, the movable panel 40 moves backward relative to the second rear link 170.

[0130] When the driving shoe 100 reaches Fig.19 In the fully open corresponding position shown, the first front link 120 is located at the rearmost position in its moving range. As a result, the movable panel 40 is located at the fully open position which is located at a position rearward of the raised position and fully opens the roof opening 25. In this way, the movable panel 40 performs an opening operation from the fully closed position to the fully open position via the tilted position and the raised position.

[0131] The function of the power transmission member 200 when the movable panel 40 is opened will be described.

[0132] Fig. 20 yes Fig.16 The sectional view along the AA line of FIG. 1 is a sectional view passing through the stopper 250 when the driving shoe 100 is in the fully closed corresponding position. Fig. 20 and Fig.21 As shown, when the driving shoe 100 is in the fully closed corresponding position, the inner upper surface 252c of the stopper 250 contacts the inner limiting surface 86a of the inner front guide 80. In addition, the inner lower surface 252d of the stopper 250 contacts the bottom wall 71 of the guide rail 70. Fig. 20 and Fig. 22 As shown, the outer upper surface 253c of the stopper 250 is in contact with the third outer limiting surface 106g of the drive shoe 100. At this point, the drive shoe 100 cannot rotate in both the first rotation direction R1 and the second rotation direction R2.

[0133] like Fig. 22As shown, in the front-to-back direction, the outer front surface 253a of the stopper 250 is opposite to the first pressing surface 106e of the drive shoe 100. That is, the drive shoe 100 is in a state where a force toward the rear can be transmitted to the stopper 250. In addition, the rotation limiting portion 260 is forced toward the rear by the force applying member 272. Therefore, the pressing portion 262 of the rotation limiting portion 260 is in contact with the contact surface 106a of the drive shoe 100. On the other hand, the pressing portion 262 of the rotation limiting portion 260 is not in contact with the stopper 250. In the following description, in the moving range of the rotation limiting portion 260, the position where the pressing surface 262a of the rotation limiting portion 260 is not in contact with the outer upper surface 253c of the stopper 250 is referred to as the "rotation allowing position".

[0134] According to the above, when the driving shoe 100 moves backward from the fully closed corresponding position, the first pressing surface 106e of the driving shoe 100 presses the outer front surface 253a of the stopper 250 backward. Therefore, the stopper 250 moves backward together with the driving shoe 100. In other words, the power transmission component 200 moves backward together with the driving shoe 100. The position when the stopper 250 and the driving shoe 100 are engaged is called an "engaged position". When the stopper 250 is located at the engaged position, the stopper 250 can move in the front-rear direction based on the power transmitted from the driving shoe 100.

[0135] Fig.23 and Fig.24 1 is a cross-sectional view of the driving shoe 100 when it moves backward from the fully closed corresponding position. Fig.23 As shown, when the driving shoe 100 moves rearward from the fully closed corresponding position, the inner protrusion 252 of the stopper 250 contacts the inner sliding surface 87a of the inner front guide 80. Here, the inclination of the inner cam surface 252e of the stopper 250 relative to the second reference direction is gentler than the inclination of the inner sliding surface 87a of the inner front guide 80 relative to the second reference direction. Therefore, the boundary between the inner rear surface 252b of the stopper 250 and the inner cam surface 252e contacts the inner sliding surface 87a of the inner front guide 80. The inner sliding surface 87a of the inner front guide 80 is inclined in a manner that it faces upward as it moves backward. Therefore, when the driving shoe 100 moves from the fully closed corresponding position, the inner protrusion 252 of the stopper 250 contacts the inner sliding surface 87a of the inner front guide 80. Fig.23 When moving rearward in the state shown, the stopper 250 slides along the inner sliding surface 87 a of the inner front guide 80 .

[0136] Fig.25 and Fig.26 2 is a cross-sectional view of the stopper 250 when it has finished sliding along the inner sliding surface 87a of the inner front guide 80. Fig.25As shown in FIG. 1 , the inner protrusion 252 of the stopper 250 is displaced upward by sliding the stopper 250 along the inner sliding surface 87a of the inner front guide 80. Fig.26 As shown in FIG. 2 , the outer protrusion 253 of the stopper 250 is displaced downward. That is, the stopper 250 rotates in the second rotation direction R2.

[0137] like Fig.25 As shown in FIG. 1 , when the stopper 250 finishes sliding along the inner sliding surface 87a of the inner front guide 80, the inner rear surface 252b of the stopper 250 contacts the inner clamping surface 87b of the inner front guide 80. In addition, when the stopper 250 finishes sliding along the inner sliding surface 87a of the inner front guide 80, as shown in FIG. Fig.26 As shown in FIG. 1 , the outer auxiliary sliding surface 106d of the driving shoe 100 contacts the second outer cam surface 253f of the stopper 250. Here, the outer auxiliary sliding surface 106d of the driving shoe 100 and the second outer cam surface 253f of the stopper 250 are both inclined upward as they move backward. Fig.26 When the state shown moves backward, the outer auxiliary sliding surface 106d of the driving shoe 100 slides along the second outer cam surface 253f of the stopper 250. Then, the outer protrusion 253 of the stopper 250 is displaced downward, and the inner protrusion 252 of the stopper 250 is displaced upward. That is, the stopper 250 further rotates in the second rotation direction R2.

[0138] Figure 27 to Figure 29 yes Fig.17 The cross-sectional view taken along line AA of FIG. 1 is a cross-sectional view passing through the stopper 250 when the driving shoe 100 is located at the corresponding position of the tilting. Figure 27 to Figure 29 This is also a cross-sectional view after the outer auxiliary sliding surface 106d of the driving shoe 100 has finished sliding along the second outer cam surface 253f of the stopper 250.

[0139] like Fig.29 As shown in FIG. 1 , when the driving shoe 100 is located at the corresponding position of the tilting, the stopper 250 does not exist behind the outer auxiliary sliding surface 106d of the driving shoe 100. Therefore, even if the driving shoe 100 moves backward, the power will not be transmitted to the stopper 250. Figure 27 to Figure 29 The position of the stop member 250 shown is referred to as the "release position". Fig. 27 As shown, the release position is a state where the stopper 250 is most rotated in the second rotation direction R2.

[0140] like Fig.28As shown, when the driving shoe 100 is located at the corresponding position of the tilting, the inner protrusion 252 of the stopper 250 is located between the two inner clamping surfaces 86c and 87b of the inner front guide 80. That is, the inner front surface 252a of the stopper 250 is opposite to the inner clamping surface 86c of the inner front guide 80, and the inner rear surface 252b of the stopper 250 is opposite to the inner clamping surface 87b of the inner front guide 80. Therefore, the stopper 250 cannot move in the front-to-back direction relative to the inner front guide 80. That is, the power transmission component 200 cannot move in the front-to-back direction. As a result, the postures of the first rear link 160 and the second rear link 170 are maintained.

[0141] like Fig. 27 and Fig.29 As shown, the outer protrusion 253 of the stopper 250 is located below the drive shoe 100. That is, the outer upper surface 253c of the stopper 250 contacts the first outer limiting surface 106c of the drive shoe 100. Therefore, the stopper 250 cannot rotate in the first rotation direction R1 from the release position.

[0142] Fig.30 2 is a cross-sectional view of the driving shoe 100 when it moves backward from the corresponding position of the tilting. Since the stopper 250 is located at the release position, the driving shoe 100 moves backward relative to the stopper 250. At this time, the first outer limiting surface 106c of the driving shoe 100 slides along the outer upper surface 253c of the stopper 250. On the other hand, the rotation limiting portion 260, which is biased backward by the force-applying component 272, moves backward together with the driving shoe 100. Therefore, as the rotation limiting portion 260 moves backward, the pressing surface 262a of the rotation limiting portion 260 contacts the outer upper surface 253c of the stopper 250. Here, the front end of the second outer cam surface 253f of the stopper 250 is inclined in a manner that it moves downward as it moves forward. Therefore, it becomes easy for the stopper 250 to penetrate below the pressing portion 262 of the rotation limiting portion 260.

[0143] So, from Fig.29 The state shown in FIG. 1 is that only the driving shoe 100 is in contact with the outer upper surface 253c of the stopper 250. Fig.30 The driving shoe 100 and the rotation limiting portion 260 shown in the figure are both in contact with the outer upper surface 253c of the stopper 250. As the driving shoe 100 moves rearward, the contact area between the driving shoe 100 and the stopper 250 becomes smaller, and the contact area between the rotation limiting portion 260 and the stopper 250 becomes larger. In the following description, the position where the pressing surface 262a of the rotation limiting portion 260 contacts the outer upper surface 253c of the stopper 250 within the moving range of the rotation limiting portion 260 is referred to as the "rotation limiting position".

[0144] When the rotation restricting portion 260 contacts the flange 233 of the extension shaft 230, the rotation restricting portion 260 cannot move backward. Therefore, after the rotation restricting portion 260 contacts the flange 233, even if the drive shoe 100 moves backward, the rotation restricting portion 260 does not move backward.

[0145] like Fig.31 As shown, when the driving shoe 100 is Fig.30 When the rotation limiting part 260 moves backward, the contact surface 106a of the driving shoe 100 moves backward relative to the outer protrusion 253 of the stopper 250. That is, the first outer limiting surface 106c of the driving shoe 100 cannot slide along the outer upper surface 253c of the stopper 250. As a result, only the pressing surface 262a of the rotation limiting part 260 is in contact with the outer upper surface 253c of the stopper 250.

[0146] The operation of the sunroof device 30 during the closing operation of the movable panel 40 will be briefly described.

[0147] like Fig.19 As shown, when the movable panel 40 is closed from the fully open position, the actuator 50 drives the driving shoe 100 forward. When the driving shoe 100 moves forward from the fully open corresponding position, the driving shoe 100 and the front support portion 110 move forward together. At this time, the front support portion 110 moves forward while maintaining the posture relative to the guide unit 60. As a result, the movable panel 40 moves forward from the fully open position while maintaining the posture relative to the guide unit 60.

[0148] like Fig.18 As shown in FIG. 1 , when the driving shoe 100 reaches the corresponding position for raising, the movable panel 40 is arranged in the raised position. When the driving shoe 100 moves forward from the corresponding position for raising, the posture of the front support portion 110 changes. Specifically, the first front link 120 and the second front link 130 are displaced in a manner of falling relative to the guide unit 60. As a result, the front end portion of the movable panel 40 is lowered.

[0149] like Fig.17As shown, when the driving shoe 100 reaches the tilting corresponding position, the movable panel 40 is configured at the tilting position. When the driving shoe 100 moves forward from the tilting corresponding position, the posture of the front support portion 110 does not change. On the other hand, when the driving shoe 100 moves forward from the tilting corresponding position, the driving shoe 100 engages with the stopper 250 of the power transmission component 200. Therefore, the power transmission component 200 becomes a state in which the power of the driving shoe 100 can be transmitted to the rear support portion 150. As a result, when the driving shoe 100 moves forward from the tilting corresponding position, the posture of the rear support portion 150 changes. In detail, the first rear link 160 and the second rear link 170 are displaced in a manner of falling relative to the guide unit 60. As a result, the rear end portion of the movable panel 40 descends.

[0150] like Fig.16 As shown, when the driving shoe 100 reaches the fully closed corresponding position, the movable panel 40 is arranged in the fully closed position. In this way, the movable panel 40 performs a closing action from the fully open position through the raised position and the tilted position to the fully closed position.

[0151] The function of the power transmission member 200 during the closing operation of the movable panel 40 will be described.

[0152] like Fig.19 As shown, when the drive shoe 100 is located at the fully open corresponding position, the stopper 250 is located at the release position, and the rotation restricting portion 260 is located at the rotation restricting position. Therefore, the stopper 250 cannot rotate from the release position toward the engagement position.

[0153] When the driving shoe 100 passes through the corresponding position of the lifting and moves toward the corresponding position of the tilting, the engagement relationship between the driving shoe 100 and the stopper 250 changes. Fig.31 and Fig.30 As shown, as the drive shoe 100 moves forward, the first outer limiting surface 106c of the drive shoe 100 contacts the outer upper surface 253c of the stopper 250. Here, since the retreat surface 106b of the drive shoe 100 is inclined downward as it moves backward, the outer upper surface 253c of the stopper 250 easily penetrates below the retreat surface 106b of the drive shoe 100 and the first outer limiting surface 106c.

[0154] So, from Fig.31 The state shown in FIG. 1 is that only the rotation restricting portion 260 is in contact with the outer upper surface 253c of the stopper 250. Fig.30The driving shoe 100 and the rotation limiting portion 260 shown in the figure are both in contact with the outer upper surface 253c of the stopper 250. When the driving shoe 100 moves further forward, the contact surface 106a of the driving shoe 100 contacts the pressing portion 262 of the rotation limiting portion 260. After the driving shoe 100 contacts the rotation limiting portion 260, the rotation limiting portion 260 and the driving shoe 100 move forward together. When the rear end of the pressing portion 262 of the rotation limiting portion 260 moves forward compared to the front end of the outer upper surface 253c of the stopper 250, the pressing surface 262a of the rotation limiting portion 260 does not contact the outer upper surface 253c of the stopper 250. That is, only the first outer limiting surface 106c of the driving shoe 100 contacts the outer upper surface 253c of the stopper 250.

[0155] Fig.32 and Fig.33 1 is a cross-sectional view of the driving shoe 100 when it moves forward from the corresponding position of the warping. Fig.33 As shown, when the driving shoe 100 moves forward from the corresponding position of the tilting, the first outer limiting surface 106c of the driving shoe 100 does not contact the outer upper surface 253c of the stopper 250. That is, the stopper 250 can rotate from the release position to the first rotation direction R1. Next, the outer sliding surface 106i of the driving shoe 100 contacts the outer protrusion 253 of the stopper 250. Here, the inclination of the first outer cam surface 253e of the stopper 250 relative to the second reference direction is gentler than the inclination of the outer sliding surface 106i of the driving shoe 100 relative to the second reference direction. Therefore, the boundary between the outer rear surface 253b of the stopper 250 and the first outer cam surface 253e contacts the outer sliding surface 106i of the driving shoe 100 moving forward. The outer sliding surface 106i of the driving shoe 100 is inclined in a manner that it faces upward as it moves backward. Therefore, when the driving shoe 100 moves from Fig.33 When moving forward in the state shown, the stopper 250 slides along the outer sliding surface 106 i of the driving shoe 100 .

[0156] Fig.34 and Fig.35 2 is a cross-sectional view of the stopper 25 when the sliding along the outer sliding surface 106i of the driving shoe 100 is completed. Fig.35 As shown in FIG. 1 , the stopper 250 slides along the outer sliding surface 106i of the driving shoe 100, and the outer protrusion 253 of the stopper 250 is displaced upward. Fig.34 As shown in FIG. 2 , the inner protrusion 252 of the stopper 250 is displaced downward. That is, the stopper 250 rotates in the first rotation direction R1.

[0157] like Fig.35As shown in FIG. 1 , when the sliding of the stopper 250 along the outer sliding surface 106i of the driving shoe 100 ends, as shown in FIG. Fig.34 As shown in FIG. 1 , the boundary between the inner front surface 252a and the inner upper surface 252c of the stopper 250 contacts the inner auxiliary sliding surface 86b of the inner front guide 80. Here, the inner auxiliary sliding surface 86b of the inner front guide 80 is inclined upward as it moves backward. Therefore, when the driving shoe 100 continues to move forward, the stopper 250 slides along the inner auxiliary sliding surface 86b of the inner front guide 80.

[0158] Fig.36 and Fig.37 2 is a cross-sectional view of the stopper 250 when the sliding of the stopper 250 along the inner auxiliary sliding surface 86b of the inner front guide 80 is completed. As the stopper 250 slides along the inner auxiliary sliding surface 86b of the inner front guide 80, the inner protrusion 252 of the stopper 250 is displaced downward, and the outer protrusion 253 of the stopper 250 is displaced upward. That is, the stopper 250 further rotates in the first rotation direction R1. In this way, the stopper 250 rotates to the engagement position.

[0159] like Fig.37 As shown in FIG. 1 , when the stopper 250 is in the engaged position, the outer rear surface 253b of the stopper 250 contacts the second pressing surface 106h of the driving shoe 100. That is, the driving shoe 100 is in a state where the force toward the front can be transmitted to the power transmission member 200 via the stopper 250. Fig.36 and Fig.37 When the drive shoe 100 moves forward in the state shown, the second pressing surface 106h of the drive shoe 100 presses the outer rear surface 253b of the stopper 250 forward. Therefore, the stopper 250 moves forward together with the drive shoe 100. In other words, the power transmission member 200 moves forward together with the drive shoe 100.

[0160] In addition, when the driving shoe 100 moves forward, the inner limiting surface 86a of the inner front guide member 80 is located directly above the inner upper surface 252c of the stopper 250. Therefore, the inner protrusion 252 of the stopper 250 cannot be displaced upward. In other words, the stopper 250 cannot rotate from the engaged position to the released position.

[0161] <Effects of the present embodiment>

[0162] (1) The stopper 250 rotates between an engagement position in which power can be transmitted from the drive shoe 100 to the rear support portion 150 and a release position in which power cannot be transmitted from the drive shoe 100 to the rear support portion 150. That is, since the stopper 250 does not move in the up-down direction between the engagement position and the release position, the sunroof device 30 can suppress an increase in thickness in the up-down direction. In addition, since the stopper 250 does not move in the width direction between the engagement position and the release position, the sunroof device 30 can suppress an increase in size in the width direction.

[0163] Furthermore, when the driving shoe 100 moves rearward toward the tilting corresponding position, the stopper 250 rotates toward the releasing position by sliding along the inner sliding surface 87a of the guide unit 60. On the other hand, when the driving shoe 100 moves forward from the tilting corresponding position, the stopper 250 rotates toward the engaging position by sliding along the outer sliding surface 106i of the driving shoe 100. Therefore, the sunroof device 30 can rotate the stopper 250 to a desired position according to the moving direction of the driving shoe 100.

[0164] The first rotation direction R1 and the second rotation direction R2 as the directions in which the stopper 250 operates are different from the first reference direction as the direction in which power is transmitted from the drive shoe 100. Therefore, the sunroof apparatus 30 can suppress malfunction of the stopper 250 based on the power transmitted from the drive shoe 100.

[0165] (2) The power transmission member 200 includes a rotation limiting portion 260 that limits the rotation of the stopper 250 from the release position toward the engagement position when the drive shoe 100 is located rearward of the tilting corresponding position. Therefore, in the sunroof device 30, when the drive shoe 100 is located rearward of the tilting corresponding position, the position of the stopper 250 can be suppressed from changing from the release position. Therefore, in the sunroof device 30, when the drive shoe 100 moves forward from the tilting corresponding position, the outer sliding surface 106i of the drive shoe 100 can be brought into contact with the stopper 250.

[0166] (3) The guide unit 60 includes the first inner engaging wall 86, which restricts the rotation of the stopper 250 from the engaging position toward the releasing position when the driving shoe 100 is located forward of the tilting corresponding position. Therefore, in the sunroof device 30, when the driving shoe 100 is located forward of the tilting corresponding position, the position of the stopper 250 can be suppressed from changing from the engaging position. Therefore, in the sunroof device 30, when the driving shoe 100 moves rearward toward the tilting corresponding position, the stopper 250 can be brought into contact with the inner sliding surface 87a of the inner front guide member 80.

[0167] (4) The stopper 250 and the rotation limiting portion 260 are supported by the stopper rod 210. Therefore, the sunroof device 30 can easily manage the positional relationship between the stopper 250 and the rotation limiting portion 260. In addition, the rotation limiting portion 260 is displaced between the rotation allowing position and the rotation limiting position by the axial movement of the stopper rod 210. In other words, the position of the rotation limiting portion 260 in the up-down direction when it is displaced between the rotation allowing position and the rotation limiting position hardly changes. Therefore, the sunroof device 30 can suppress the increase in thickness in the up-down direction in order to ensure the movement range of the rotation limiting portion 260.

[0168] (5) In the sunroof device 30, when the driving shoe 100 is located forward of the tilt-up corresponding position, the first outer limiting surface 106c of the driving shoe 100 limits the rotation of the stopper 250. On the other hand, when the driving shoe 100 is located backward of the tilt-up corresponding position, the pressing surface 262a of the rotation limiting portion 260 limits the rotation of the stopper 250. Furthermore, when the object that limits the rotation of the stopper 250 is switched from one of the driving shoe 100 and the rotation limiting portion 260 to the other, there is a state in which both the driving shoe 100 and the rotation limiting portion 260 limit the rotation of the stopper 250. Therefore, in the sunroof device 30, when the state in which one of the driving shoe 100 and the rotation limiting portion 260 is in contact with the stopper 250 is shifted to the state in which the other is in contact with the stopper 250, it is possible to suppress a significant change in the posture of the stopper 250 or the generation of abnormal noise.

[0169] (6) The power transmission member 200 includes the urging member 272 that urges the rotation restricting portion 260 from the rotation allowing position toward the rotation restricting position. That is, the power transmission member 200 can move the rotation restricting portion 260 between the rotation allowing position and the rotation restricting position in conjunction with the position of the drive shoe 100.

[0170] (7) In the sunroof device 30, when the drive shoe 100 is located behind the tilt-up corresponding position, the two inner clamping surfaces 86c and 87b of the guide unit 60 clamp the stopper 250 in the front-rear direction. Therefore, when the drive shoe 100 is located behind the tilt-up corresponding position, the front-rear movement of the power transmission member 200 is restricted. Therefore, the sunroof device 30 can suppress the power transmission member 200 from moving due to the load acting on the rear support portion 150, or the rear support portion 150 from moving due to the load acting on the power transmission member 200.

[0171] (8) The two inner clamping surfaces 86c, 87b of the guide unit 60 intersect the first reference direction at an angle close to a right angle. Therefore, even if an external force in the front-rear direction acts on the power transmission component 200, it is difficult for the stopper 250 to slide along the two inner clamping surfaces 86c, 87b of the guide unit 60. In other words, it is difficult for the stopper 250 to move in the up-and-down direction relative to the two inner clamping surfaces 86c, 87b of the guide unit 60. In this regard, the sunroof device 30 can further limit the movement of the stopper 250 in the release position.

[0172] (9) The stopper 250 rotates from the engaged position to the released position by the drive shoe 100 moving rearward toward the tilted position. Specifically, the stopper 250 starts to rotate from the engaged position by sliding along the inner sliding surface 87a of the guide unit 60. Thereafter, the stopper 250 rotates to the released position by sliding along the outer auxiliary sliding surface 106d of the drive shoe 100. In this way, the sunroof device 30 causes the stopper 250 to slide along the outer auxiliary sliding surface 106d of the drive shoe 100 in addition to the inner sliding surface 87a of the guide unit 60. As a result, the sunroof device 30 can arrange the stopper 250 between the two inner clamping surfaces 86c and 87b of the guide unit 60 at the released position.

[0173] (10) The inner front guide 80 of the guide unit 60 has the inner sliding surface 87a, and the drive shoe 100 has the outer sliding surface 106i. Therefore, compared with a case where one of the guide unit 60 and the drive shoe 100 has a structure corresponding to both the inner sliding surface 87a and the outer sliding surface 106i, the complexity of the structure of the device can be suppressed.

[0174] (11) When the drive shoe 100 moves rearward, the first pressing surface 106e of the drive shoe 100 presses the outer front surface 253 of the stopper 250 rearward. On the other hand, when the drive shoe 100 moves forward, the second pressing surface 106h of the drive shoe 100 presses the outer rear surface 253b of the stopper 250 forward. Here, the first pressing surface 106e and the second pressing surface 106h of the drive shoe 100 intersect the outer front surface 253a and the outer rear surface 253b of the stopper 250 at an angle close to a right angle to the first reference direction. Therefore, when the drive shoe 100 presses the stopper 250 in the front-rear direction, it is difficult for a torque to be generated in the stopper 250. Therefore, in the sunroof device 30, when the drive shoe 100 presses the stopper 250 in the front-rear direction, it is possible to suppress an increase in the sliding resistance between the stopper 250 and the guide rail 70.

[0175] (12) The stopper 250 is clamped in the front-to-back direction by the two inner clamping surfaces 86c and 87b of the inner front guide 80 at the release position. Specifically, the inner front surface 252a of the stopper 250 is opposite to the inner clamping surface 86c of the inner front guide 80, and the inner rear surface 252b of the stopper 250 is opposite to the inner clamping surface 87b of the inner front guide 80. Therefore, when a force toward the front acts on the power transmission member 200, a load toward the rear acts on the inner front surface 252a of the stopper 250 through contact with the inner clamping surface 86c. In addition, when an external force toward the rear acts on the power transmission member 200, a load toward the front acts on the inner rear surface 252b of the stopper 250 through contact with the inner clamping surface 87b. As a result, stress concentration may occur near the opening of the support hole 254 of the stopper 250. In this regard, in the stopper 250, the outer front surface 253a is recessed rearward relative to the front end surface of the base 251, and the outer rear surface 253b is recessed forward relative to the rear end surface of the base 251. Therefore, the sunroof device 30 can alleviate the stress concentration generated near the opening of the support hole 254 of the stopper 250.

[0176] <Change Example>

[0177] This embodiment can be implemented by modification as follows. This embodiment and the following modification examples can be implemented in combination with each other within the range that there is no technical contradiction.

[0178] The inner sliding surface 87a of the guide unit 60 and the outer auxiliary sliding surface 106d of the driving shoe 100 are structures for rotating the stopper 250 from the engagement position to the release position by sliding the stopper 250 when the driving shoe 100 moves backward. Therefore, one of the inner sliding surface 87a of the guide unit 60 and the outer auxiliary sliding surface 106d of the driving shoe 100 can be omitted. For example, when the inner sliding surface 87a of the guide unit 60 is omitted, the outer auxiliary sliding surface 106d of the driving shoe 100 is equivalent to the "first sliding surface". In addition, when the inner sliding surface 87a of the guide unit 60 is omitted, the shape of the outer auxiliary sliding surface 106d of the driving shoe 100 is preferably changed appropriately.

[0179] Similarly, the outer sliding surface 106i of the driving shoe 100 and the inner auxiliary sliding surface 86b of the guide unit 60 are structures for rotating the stopper 250 from the release position to the engagement position by sliding the stopper 250 when the driving shoe 100 moves forward. Therefore, one of the outer sliding surface 106i of the driving shoe 100 and the inner auxiliary sliding surface 86b of the guide unit 60 can be omitted. For example, when the outer sliding surface 106i of the driving shoe 100 is omitted, the inner auxiliary sliding surface 86b of the guide unit 60 is equivalent to the "second sliding surface". In addition, when the outer sliding surface 106i of the driving shoe 100 is omitted, the shape of the inner auxiliary sliding surface 86b of the guide unit 60 is preferably changed appropriately.

[0180] In the sunroof device 30 , the inner front guide 80 and the outer front guide 90 can be omitted. In this case, the guide rail 70 preferably includes a structure corresponding to the inner restriction surface 86a , the inner auxiliary sliding surface 86b , and the inner clamping surfaces 86c , 87b of the inner front guide 80 .

[0181] The inner holding surfaces 86c and 87b of the inner front guide 80 may be omitted. In this case, the sunroof device 30 preferably further includes a structure for preventing the posture of the rear support portion 150 from changing when the drive shoe 100 moves between the tilt-up corresponding position and the fully open corresponding position.

[0182] The outer engaging wall 106 of the driving shoe 100 has a plurality of surfaces for pushing the stopper 250 or for the stopper 250 to slide. Furthermore, when the driving shoe 100 moves in the front-rear direction, the surface of the plurality of surfaces of the outer engaging wall 106 of the driving shoe 100 that contacts the stopper 250 is switched. Therefore, the inclination of the plurality of surfaces of the outer engaging wall 106 of the driving shoe 100 is preferably set in a manner that does not generate abnormal sound and resistance. For example, the plurality of surfaces of the outer engaging wall 106 of the driving shoe 100 may also be curved surfaces. The same is true for the plurality of surfaces of the inner front guide 80.

[0183] The rotation restricting portion 260 does not necessarily restrict the rotation of the stopper 250 by surface contact. For example, the rotation restricting portion 260 may restrict the rotation of the stopper 250 by point contact or line contact. The same is true for the first outer restricting surface 106c of the drive shoe 100.

[0184] The rotation restricting portion 260 may restrict the rotation of the stopper 250 in other ways. For example, the stopper 250 may be formed as a magnetic body and the rotation of the stopper 250 may be restricted by using magnetic force.

[0185] The pressing portion 262 of the rotation restricting portion 260 only needs to restrict the rotation of the stopper 250, and does not need to be in contact with the outer upper surface 253c of the stopper 250. For example, the pressing portion 262 of the rotation restricting portion 260 may restrict the rotation of the stopper 250 by contacting the inner lower surface 252d of the stopper 250. In this case, the pressing portion 262 of the rotation restricting portion 260 may be located between the bottom wall 71 of the guide rail 70 and the inner lower surface 252d of the stopper 250 when restricting the rotation of the stopper 250.

[0186] The urging member 272 does not need to be a coil spring as long as it can urge the rotation restricting portion 260. For example, the urging member 272 may be an elastic body.

[0187] One of the inner sliding surface 87a and the outer sliding surface 106i, which are structures for rotating the stopper 250, can be omitted. For example, in the case where the inner sliding surface 87a of the guide unit 60 is omitted, the sunroof device 30 preferably includes a force-applying component that applies force to the stopper 250 toward the release position. Thus, when the drive shoe 100 moves rearward toward the corresponding position of the tilting, the stopper 250 rotates toward the release position by the force of the force-applying component. On the other hand, when the drive shoe 100 moves forward from the corresponding position of the tilting, the stopper 250 rotates toward the engagement position by sliding along the outer sliding surface 106i of the drive shoe 100. Examples of the force-applying component include a spring and a magnet. In addition, in the case where the inner sliding surface 87a of the guide unit 60 is omitted, the rotation limiting portion 260 can also be omitted.

[0188] The first inner engaging wall 86 and the rotation restricting portion 260, which are structures for restricting the rotation of the stopper 250, can be omitted. In this case, the difference between the outer diameter of the first shaft portion 231 of the stopper lever 210 and the outer diameter of the support hole 254 of the stopper 250 can be reduced so that the stopper 250 rotates only when a sufficient torque acts on the stopper 250. In addition, when one of the first inner engaging wall 86 and the rotation restricting portion 260 is omitted, as described above, the stopper 250 can be urged in the corresponding rotation direction by the urging member.

[0189] In the movable panel 40, the front bracket 42 and the rear bracket 43 may be connected in the front-rear direction. That is, the front bracket 42 and the rear bracket 43 may be integrally formed.

[0190] The front and rear of the sunroof device 30 may not coincide with the front and rear of the vehicle 10. For example, the front of the sunroof device 30 may be the rear of the vehicle 10, and the rear of the sunroof device 30 may be the front of the vehicle 10.

The movable panel is moved in a forward and backward direction from the fully open position to the fully closed position when the driving shoe moves forward. The front supporting part moves the movable panel in the front-to-rear direction based on the power transmitted from the driving shoe. The rear supporting part raises and lowers the rear end of the movable panel based on the power transmitted from the driving shoe via the power transmission component, so that the movable panel moves between the fully closed position and the tilted position. The power transmission component has a stopper, which is in an engagement position and a stopper capable of transmitting power from the driving shoe to the rear supporting part.

When the driving shoe moves forward toward the corresponding position to be tilted, the driving shoe transfers from a state where only the first front limiting surface is in contact with the stopper via a state where both the first front limiting surface and the first rear limiting surface are in contact with the stopper to a state where only the first rear limiting surface is in contact with the stopper.

[0205] [Method 7]

[0206] In the sunroof device described in Method 5 or Method 6, the power transmission component has a force-applying component, which applies force to the first limiting portion from the rotation allowing position toward the rotation limiting position. When the driving shoe moves forward, the first limiting portion is displaced toward the rotation allowing position by being pushed by the driving shoe. On the other hand, when the driving shoe moves backward, the first limiting portion is displaced toward the rotation limiting position by being force-applied by the force-applying component.
