Description

  The present invention relates to a vehicle sunroof device in which a sunroof panel for opening and closing a roof opening opened in a vehicle roof is composed of a front panel and a rear panel.

In recent years, in a sunroof device for a vehicle, development of a technique for increasing the opening amount of the roof opening as much as possible has been advanced. In the method of opening and closing the roof opening with one sunroof panel, there is a limit to increasing the opening amount. On the other hand, a method of subdividing the sunroof panel is conceivable. However, it is not a good idea because the composition becomes complicated if it is subdivided too much. Therefore, a technique of a system in which the sunroof panel is divided into the front panel and the rear panel in the front and rear directions has been developed (see, for example, Patent Document 1).
Japanese Utility Model Publication 4-26254

A conventional vehicle sunroof device disclosed in Patent Document 1 is configured to open and close a front panel and a rear panel separately by a wire cable by pushing and pulling a wire cable (transmission member) with a motor. . Specifically, the front panel and the rear panel in the fully closed state are opened in the following order.
First, the rear end of the front panel tilts upward (tilt up).
Next, the front panel retracts along the outer surface of the roof and opens to the half-open position.
Next, the rear panel descends below the inner surface of the roof.
Finally, the rear panel retracts along the inner surface of the roof and opens to the fully open position, while the front panel retracts along the outer surface of the roof and opens to the fully opened position.

As described above, when the front panel moves backward and approaches the rear panel, the fully closed rear panel starts to descend. For this reason, the timing for the rear panel to move backward is delayed by the amount of lowering. Since the front panel and the rear panel are interlocked via the wire cable, the front panel approaches the rear panel that is being lowered. Care must be taken so that the retracted front panel does not hit the rear panel.
On the other hand, it is conceivable to advance the timing at which the rear panel starts to open. However, if the opening start timing is advanced, the front panel does not yet reach the fully open position when the rear panel reaches the fully open position. In this case, since both the front panel and the rear panel cannot be fully opened, the roof opening cannot be opened largely.

  It is an object of the present invention to provide a technique capable of opening and closing a roof opening largely without causing interference between a front panel and a rear panel.

In the invention according to claim 1, the sunroof panel for opening and closing the roof opening opened in the roof of the vehicle is composed of the front panel and the rear panel, and the front panel and the rear panel are in a fully closed state. Sometimes, depending on the driving force of the electric motor, after the rear end of the front panel is tilted upward, the front panel moves backward along the outer surface of the roof to be in a half-open state, and then the rear panel Is a vehicle sunroof device that is fully opened by retreating along the inner surface of the roof and retreating the front panel along the outer surface of the roof,
A rear panel drive mechanism for raising and lowering and opening and closing the rear panel is provided. The rear panel drive mechanism is configured to raise the front end of the rear panel that restricts the rise of the front end of the rear panel when the rear end of the rear panel in the fully closed state is lowered. It is characterized by having a regulation part.

  According to a second aspect of the present invention, in the first aspect, the rear panel drive mechanism includes a rear panel support stay that supports the rear panel, and the rear panel support stay is slidable back and forth on the roof and swingable up and down. The panel front end rise restricting portion is provided on the roof at a position in front of the rear panel when in the fully closed state, and a stay extension portion extending from the rear panel support stay toward the front panel. It is provided with a stopper member that restricts movement and restricts the upper limit of swing of the stay extension.

  According to a third aspect of the present invention, in the second aspect, when the rear panel is in a fully closed state, the stopper member restricts the upper and lower slides of the stay extension portion in addition to restricting the upper swing limit of the stay extension portion. When the front end portion of the rear panel is lowered, the stay extension portion is allowed to slide back and forth.

  According to a fourth aspect of the present invention, in the third aspect, the stopper member has a substantially arc-shaped guide groove that guides the tip of the stay extension portion, and one end of the guide groove is formed on the rear panel. When the front end portion of the guide groove is lowered, the tip end portion is opened so as to be able to enter and exit, the other end of the guide groove is disposed higher than one end of the guide groove, and the rear panel is fully closed. Further, the front end portion is closed so as to restrict the ascent and the front / rear slide.

  In the invention according to claim 1, when the fully closed rear panel is retracted along the inner surface of the roof, the rear end portion of the rear panel is controlled by the panel front end rise restricting portion so that the front end portion of the rear panel does not rise. Can be lowered. Since the front end portion does not rise when the rear end portion is lowered, there is no fear of hitting the rear panel even if the front panel is retracted by that much. It is only necessary to start opening the rear panel when the retracted front panel approaches the front end of the rear panel. That is, the timing at which the rear panel starts to open can be delayed by the amount that the front end of the rear panel does not rise. By delaying the opening start timing, the front panel and the rear panel can reach the fully open position simultaneously. Since both the front panel and the rear panel can be fully opened, a large roof opening can be opened widely. As a result, the opening amount when the sunroof panel is fully opened increases.

In the invention according to claim 2, a panel front end rise restricting portion having a simple structure comprising a combination of a stay extension portion provided on a rear panel support stay for supporting the rear panel and a stopper member for restricting an upper swing limit of the stay extension portion. Thus, the front end portion of the rear panel can be reliably regulated so as not to rise.
In addition, since the stopper member is provided at a position in front of the rear panel when in the fully closed state, the movement of the stopper member is restricted with respect to the roof, so that the front end portion of the rear panel can be more reliably restricted. can do.

In the invention according to claim 3, when the rear panel is in the fully closed state, the upper limit of swing and the front / rear slide of the stay extension portion are restricted by the stopper member. For this reason, the front-end part of a rear panel can be reliably maintained in a fully closed state.
On the other hand, when the front end portion of the rear panel is lowered, the stay extension portion can freely slide back and forth. For this reason, the roof opening can be smoothly opened and closed by sliding the rear panel back and forth.

In the invention which concerns on Claim 4, the stopper member has a substantially circular arc-shaped guide groove for guiding the front-end | tip part of a stay extension part. The substantially arc-shaped guide groove has a closed other end (closed end) disposed higher than an open end (open end). For this reason, when the rear panel is in the fully closed state, the tip portion is restricted from rising and sliding back and forth by the closed end. When the front end portion of the rear panel is lowered, the front end portion can freely enter and exit from the open end. The rear panel protruding from the open end can be slid back and forth along the inner surface of the roof. Furthermore, the substantially arc-shaped guide groove allows the tip portion to be moved extremely smoothly between the closed end at the upper limit position and the open end at the lower limit position.
Thus, the opening / closing operation of the front end portion of the rear panel can be smoothly performed with only a very simple configuration in which the tip portion of the stay extension portion is guided by the substantially arc-shaped guide groove whose upper end is closed. it can.

  The best mode for carrying out the present invention will be described below with reference to the accompanying drawings. "Front", "Rear", "Left", "Right", "Up", "Down" follow the direction seen from the driver, Fr is front, Rr is rear, Le is left, Ri is right CL indicates the vehicle width center (vehicle body center).

The speed reducer 36 operates to pull out the pair of left and right wire cables 37, 37 toward the front panel drive mechanisms 38, 38, and on the other hand pulls back the left and right wire cables 37, 37.

  The wire cables 37, 37 (push-pull cables 37, 37) are pulled back by the speed reducer 36, thereby pulling the front sliders 50, 50 in the left and right front panel drive mechanisms 38, 38 backward (arrow Pr direction). . Further, the wire cables 37 and 37 are pushed out from the speed reducer 36 to push the left and right front sliders 50 and 50 forward (in the direction of the arrow Pf).

The left and right front panel drive mechanisms 38 and 38 are mechanisms for opening and closing the front panel 32. The left and right rear panel drive mechanisms 39, 39 are mechanisms that open and close the rear panel 33 in conjunction with the left and right front panel drive mechanisms 38, 38, and are arranged behind the left and right front panel drive mechanisms 38, 38. .
According to such a vehicle sunroof device 30, the front panel 32 and the rear panel 33 can be opened and closed by an automatic operation mode or a manual operation mode by the electric motor 35.

The vehicle sunroof device 30 opens and closes as shown in FIGS. 2 to 4 according to the driving force of the electric motor 35.
FIGS. 2A and 2B show the vehicle sunroof device 30 when both the front panel 32 and the rear panel 33 are in a fully closed state. As shown in FIG. 2A, when both the front panel 32 and the rear panel 33 are in a fully closed state (closed), the panels 32 and 33 have the following relationship with respect to the roof opening 12. The front end surface of the front panel 32 is sealed and in contact with the front end edge of the roof opening 12. The rear end surface of the front panel 32 is sealed and in contact with the front end surface of the rear panel 33. The rear end surface of the rear panel 33 is sealed and in contact with the rear end edge of the roof opening 12.
Hereinafter, the position FPc of the front end surface of the front panel 32 in the fully closed state is referred to as “a fully closed position FPc” of the front panel 32. Further, the position RPc of the front end surface of the rear panel 33 in the fully closed state is referred to as a “fully closed position RPc” of the rear panel 33.

  3A to 3C show the vehicle sunroof device 30 when only the front panel 32 is in a half-open state. As shown in FIG. 3A, when the front panel 32 is in a half open state (half open), the front end face of the front panel 32 is at a position FPh. Hereinafter, the position FPh of the front end face of the front panel 32 in the half-open state is referred to as “half-open position FPh” of the front panel 32.

  FIG. 4 shows the vehicle sunroof device 30 when both the front panel 32 and the rear panel 33 are fully open. When both the front panel 32 and the rear panel 33 are fully opened (full open), the front end face of the front panel 32 is at the position FPo. At this time, the front end face of the rear panel 33 is at the position RPo. Hereinafter, the position FPo of the front end face of the front panel 32 in the fully opened state is referred to as “fully opened position FPo” of the front panel 32. Further, the position RPo of the front end face of the rear panel 33 in the fully open state is referred to as a “fully open position RPo” of the rear panel 33.

The sunroof panel 31 is opened (opened) as follows.
Now, as shown in FIG. 2A, both the front panel 32 and the rear panel 33 are in a fully closed state. Thereafter, for example, by fully opening an operation switch (not shown), the electric motor 35 (see FIG. 1) rotates forward. As a result, first, the rear end of the front panel 32 tilts upward (becomes indicated by an imaginary line). Next, the front panel 32 moves backward along the outer surface 11a of the roof 11 and is in a half-open state as shown in FIG. Next, the rear panel 33 is retracted along the inner surface 11 b of the roof 11, and the front panel 32 is retracted along the outer surface 11 a of the roof 11, so that the fully open state is achieved as shown in FIG. 4.

As shown in FIG. 4, the opening length from the front end edge (position FPc) to the rear end edge in the roof opening 12 is L1. On the other hand, when the sunroof panel 31 is in the fully open state, the separation dimension from the front end edge (position FPc) of the roof opening 12 to the front end face (position FPo) of the front panel 32 is L2. Accordingly, the opening ratio Ro (%) of the roof opening 12 is obtained by the following equation.
Ro = (L2 / L1) × 100

The sunroof panel 31 is closed (closed) as follows.
Now, as shown in FIG. 4, both the front panel 32 and the rear panel 33 are fully open. Thereafter, for example, by fully closing an operation switch (not shown), the electric motor 35 (see FIG. 1) is reversed. As a result, first, the rear panel 33 moves forward along the inner surface 11 b of the roof 11, and the front panel 32 moves forward along the outer surface 11 a of the roof 11. As a result, as shown in FIG. 3A, the rear panel 33 is in the original fully closed state, and the front panel 32 is in the half open state. Next, the front panel 32 further moves forward along the outer surface 11a of the roof 11, and returns to the original fully closed position shown in FIG. Next, the front panel 32 is closed by returning the rear end of the tilted state to the original height.

Here, it defines as follows. Tilting the rear end of the front panel 32 upward is called “tilt up”. The tilting of the rear end of the front panel 32 to the upper limit is referred to as “tilt up completion”. On the other hand, lowering the rear end of the front panel 32 tilted upward and returning it to the original height is called “tilt down”. The fact that the rear end of the front panel 32 returns to the original height is called “tilt down completion”.
Opening the front panel 32 and the rear panel 33 by sliding them backward is called “sliding open”. The completion of the backward slide is called “slide fully open”. Closing the front panel 32 and the rear panel 33 by sliding them forward is called “sliding closing”. The completion of the forward slide is called “slide fully closed”.

Next, the left side frame member 22 and the left front panel drive mechanism 38 will be described. Since the right side frame member 22 and the right front panel drive mechanism 38 have the same configuration as the left (symmetric configuration), description thereof is omitted.
5 shows an exploded view of the left front panel drive mechanism 38 shown in FIG. FIG. 6 shows an assembly configuration of the left front panel drive mechanism 38 shown in FIG. In FIG. 6, in order to facilitate understanding of the description, the configuration of the front panel drive mechanism 38 is shown separately in (a) and (b).

  As shown in FIG. 5, the left side frame member 22 has a guide groove 22a extending in the front-rear direction. The guide groove 22a is open at the top and has flanges 22b and 22b on the left and right edges that are open.

  As shown in FIGS. 5 and 6, the left front panel drive mechanism 38 includes a front slider 50, a stay slider 60, a connection link 70, a stopper member 80, a front panel support stay 90, and a retracting arm 100.

  The front slider 50 is a member that can slide back and forth with respect to the roof 11, and includes a horizontal plate-like slide plate 51 and a vertical plate-like lift guide plate 52. The slide plate 51 is a member that is guided by the guide groove 22a so as to be slidable back and forth, and has an engaging groove 53 at the front. The engaging groove 53 is open at the top and extends in the vehicle width direction. The lift guide plate 52 is a flat plate that stands up and down from the slide plate 51 and has a lift guide groove 54 formed on a side surface, and an arm hooking projection 55 that extends laterally from the rear end portion. Yes. The lift guide groove 54 is an inclined groove formed to have a downward slope toward the rear. The lift guide groove 54 may be a long hole penetrating in the vehicle width direction.

  The stay slider 60 is a member that is disposed in front of the front slider 50 and that can slide back and forth with respect to the roof 11. The stay slider 60 is a longitudinally elongated member disposed in the guide groove 22a so as to be slidable in the front-rear direction, and includes a connecting pin 61 extending from the rear side to a side, a support recess 62 formed at the front end, and a side surface. The swing guide groove 63 is formed.

  The connecting link 70 is a member that is elongated in the front-rear direction and capable of connecting the front slider 50 and the stay slider 60. The connecting link 70 is formed on the first engaging convex portion 71 extending laterally from the rear lower side surface, the second engaging convex portion 72 extending laterally from the rear upper side surface, and the front side surface. Connecting hole 73 formed. The first engagement convex portion 71 can be engaged with the engagement groove 53 of the front slider 50. With respect to the first engaging convex portion 71, the second engaging convex portion 72 extends in the same direction. The connection hole 73 is fitted to the connection pin 61 of the stay slider 60.

The stopper member 80 is a member that is disposed rearward of the stay slider 60 and is attached to the left flange 22b and elongated in the front-rear direction. The stopper member 80 has a cam groove 81 on the lower surface and a cam crest 82 on the upper surface.
The cam groove 81 faces the guide groove 22 a of the side frame member 22. The cam groove 81 can be engaged with the first engagement convex portion 71 of the connection link 70. The front surface of the stopper member 80 is the top of the surface of the cam crest 82, and is formed as a sloped surface that descends from the top toward the rear. The surface of the cam crest 82 can be engaged with the second engaging convex portion 72 of the connecting link 70.

  The front panel support stay 90 is a member that supports the front panel 32 and is capable of sliding back and forth with respect to the roof 11 and swinging up and down. The front panel support stay 90 is elongated in the front-rear direction, and includes a swing pin 91 that extends laterally from the front end, a guide pin 92 that extends laterally behind the swing pin 91, and a rearward direction relative to the guide pin 92. , A lift pin 93 extending laterally, and an engagement pin 94 extending laterally from the rear end portion.

  The swing pin 91 is fitted into the support recess 62 of the stay slider 60. The guide pin 92 is fitted in the swing guide groove 63 of the stay slider 60. The lift pin 93 is fitted in the lift guide groove 54 of the front slider 50. The combined structure of the lift guide groove 54 and the lift pin 93 that is movable by being guided by the lift guide groove 54 forms a swing guide mechanism 96.

  Because of the above configuration, the front panel support stay 90 can swing up and down using the swing pin 91 at the front end as a swing base end. When the front slider 50 slides back and forth, the lift pin 93 is guided in the lift guide groove 54, whereby the front panel support stay 90 is driven to swing up and down. Thus, the front slider 50 can swing the rear end of the front panel support stay 90 up and down via the swing guide mechanism 96.

  The retractable arm 100 is a member that is elongated in the front and rear direction. The pull-in groove 101 is an inclined groove that is formed so that the front end is open and has a downward slope, and the engagement pin 94 of the front panel support stay 90 can be fitted therein.

The lead-in groove 101 has the following two functions.
The first function is when the front panel 32 is opened, and when the rear end of the front panel 32 starts to tilt upward, the engagement pin 94 (the rear end portion of the front panel support stay 90) is guided upward. It is to support with.
The second function is to close the front panel 32 and pull it downward while supporting the rear end of the front panel support stay 90 when the rear end of the tilted state has been returned to its original height. It is.
Since it has the 1st and 2nd function, when the front panel 32 is swung up and down, it can prevent that the front panel 32 fluctuates up and down by the influence of running wind.

  The reason why the retractable arm 100 is formed of a separate member with respect to the front slider 50 is as follows. That is, when the front panel 32 is slid rearward and fully opened, the rear end of the retractable arm 100 can hit the rear edge of the frame-side opening 21 (see FIG. 1). The retractable arm 100 that hits the rear edge can move forward against the elastic force of the compression coil spring 102. Therefore, the front slider 50 and the retracting arm 100 do not interfere with the rear edge of the opening 21. This is the reason why the retractable arm 100 is formed of a separate member with respect to the front slider 50.

  Next, the operation of the front panel drive mechanism 38 will be described based on FIGS. 6 to 8 with reference to FIGS. 7 and 8, the structure of the front panel drive mechanism 38 is divided into (a) and (b), as in FIG. 6, in order to facilitate understanding of the description.

  FIG. 6 shows the front panel drive mechanism 38 when the front panel 32 is fully closed. As shown in FIGS. 2A and 6A, the front panel support stay 90 is at the lowest position in the fully closed state. The front panel support stay 90 has a lift pin 93 at the rear portion of the lift guide groove 54 and an engagement pin 94 at the rear portion of the retracting groove 101.

As shown in FIG. 6B, the second engaging convex portion 72 of the connecting link 70 is in contact with the vicinity of the top portion of the cam peak 82 of the stopper member 80. For this reason, while the 1st engagement convex part 71 is fitted in the cam groove 81 of the stopper member 80, the lower part protrudes below.
On the other hand, the front slider 50 is located close to the stay slider 60. For this reason, the engagement groove 53 of the front slider 50 is located in front of the stopper member 80.

  Thereafter, for example, when an operation switch (not shown) is fully opened, the electric motor 35 (see FIG. 1) rotates forward and pulls the wire cable 37 back. The wire cable 37 slides the front slider 50 by pulling it backward (in the direction of the arrow Pr). As a result, the engagement groove 53 approaches the first engagement protrusion 71. At the same time, the lift guide groove 54 and the retracting groove 101 move backward. The front panel support stay 90 swings upward at the rear end portion with the swing pin 91 as a swing base end. The rear end of the front panel 32 swings upward (tilts up). The result is shown in FIG.

FIG. 7 shows the front panel drive mechanism 38 when the rear end of the front panel 32 is tilted upward to the upper limit (in a tilt-up completed state). As shown in FIG. 7A, the front panel support stay 90 has the lift pin 93 at the front portion of the lift guide groove 54 and the engagement pin 94 in the upper position after coming out of the pull-in groove 101. At this time, the engagement groove 53 engages with the first engagement protrusion 71 protruding downward from the cam groove 81.
Thereafter, the wire cable 37 slides the front slider 50 further rearward. As a result, when the front edge of the engagement groove 53 hits the first engagement protrusion 71, the first engagement protrusion 71 comes out of the cam groove 81 and fits into the engagement groove 53. The result is shown in FIG.

  FIG. 8 shows the front panel drive mechanism 38 when the rear end of the front panel 32 starts moving backward with the rear end tilted upward. The state shown in FIG. 8A is almost the same as the state shown in FIG. In FIG. 8B, the stay slider 60 is connected to the front slider 50 via the connection link 70 because the first engagement protrusion 71 is disengaged from the cam groove 81 and fits into the engagement groove 53. Indicates the state. In this state, the second engaging convex portion 72 can move rearward while descending the top of the cam peak 82.

  Thereafter, the wire cable 37 slides the front slider 50 further rearward. The stay slider 60 connected to the front slider 50 via the connection link 70 also slides backward. As a result, the front panel 32 moves rearward together with the front slider 50, the stay slider 60, and the front panel support stay 90 until the front panel 32 is fully opened. When the front panel 32 is fully opened, the electric motor 35 (see FIG. 1) stops.

  Thereafter, for example, when an operation switch (not shown) is fully closed, the electric motor 35 (see FIG. 1) reverses and pushes out the wire cable 37. The wire cable 37 slides the front slider 50 by pushing it forward (arrow Pf direction). The stay slider 60 connected to the front slider 50 via the connection link 70 also slides forward. As a result, the front panel 32 moves forward together with the front slider 50, the stay slider 60, and the front panel support stay 90. At the same time, the first and second engaging protrusions 71 and 72 in the connection link 70 also move forward. The result is shown in FIG.

  As shown in FIG. 7, when the first engaging convex portion 71 moves to a position directly below the cam groove 81 of the stopper member 80, the second engaging convex portion 72 is guided by the cam crest 82 and moved forward and upward. Moving. As a result, the rear end portion of the connecting link 70 swings upward, so that the first engagement convex portion 71 comes out of the engagement groove 53 of the front slider 50 and fits into the cam groove 81.

  At this point, the connection state of the connection link 70 and the stay slider 60 to the front slider 50 is released. Even if the front slider 50 slides further forward, the stay slider 60 remains stopped. When the stay slider 60 stops, the front panel support stay 90 and the front panel 32 stop moving forward. That is, the front panel 32 has moved forward to the original fully closed position by the slide.

  Thereafter, the wire cable 37 slides the front slider 50 further forward. For this reason, the lift guide groove 54 and the retracting groove 101 move forward. The lift pins 93 of the front panel support stay 90 are guided by the lift guide grooves 54 and descend. The front panel support stay 90 swings downward at the rear end portion with the swing pin 91 as a swing base end. The rear end of the front panel 32 swings downward (tilts down). The result is shown in FIG.

  As shown in FIG. 6A, the swing of the front panel support stay 90 stops when the lift pin 93 is guided to the lift guide groove 54 and lowered to the lowest end. As a result, the front panel 32 returns to the original fully closed state. Thereafter, the electric motor 35 (see FIG. 1) stops.

  Next, the left side frame member 22 and the left rear panel drive mechanism 39 (see FIG. 2) will be described. Since the right side frame member 22 and the right rear panel drive mechanism 39 have the same configuration as the left (symmetric configuration), description thereof is omitted.

  FIG. 9 is an exploded view of the left rear panel drive mechanism 39 shown in FIG. FIG. 10 shows an assembly configuration around the front portion of the rear slider 110 in the rear panel drive mechanism 39 shown in FIG. In FIG. 10, in order to facilitate understanding of the description, the configuration around the rear slider 110 is divided into (a), (b), and (c).

  As shown in FIG. 9, the left rear panel drive mechanism 39 includes a rear slider 110, a swing member 120, a fixing member 130, a biasing member 141, a slider connecting portion 150, a rear panel support stay 170, and a stopper member 180.

  As shown in FIGS. 2 and 10, the rear slider 110 is a member that can slide back and forth with respect to the roof 11, and is disposed behind the front slider 50. The rear slider 110 drives the rear panel support stay 170 back and forth and swings up and down with respect to the roof 11. The rear panel support stay 170 is a member that supports the rear panel 33. Details of the rear panel support stay 170 will be described later.

As shown in FIG. 9, the rear slider 110 includes a pair of front and rear horizontal slide plates 111 and 111 and a pair of left and right vertical plate lift guide plates 112 and 112.
The front and rear slide plates 111 are members that are guided in the guide groove 22a so as to be slidable in the front-rear direction. The left and right lift guide plates 112 and 112 are elongate flat plates standing from the slide plates 111 and 111 and have a pair of front and rear pins 113 and 114. The front pin 113 arranged at the front part of the lift guide plates 112 and 112 and the rear pin 114 arranged at the rear part of the lift guide plates 112 and 112 are arranged horizontally so as to extend in the vehicle width direction. One of the left and right lift guide plates 112, 112 has an extension 115 extending toward the front slider 50. The extension 115 has a spring hook 116 that extends laterally from the side surface, and a long hole 117 formed in the extension tip. The long hole 117 penetrates laterally and is formed to be elongated vertically.

  9 and 10, the swing member 120 is attached to the front pin 113 of the rear slider 110 so as to extend from the rear slider 110 toward the front slider 50 (particularly toward the rear end of the lift guide plate 52). It is an elongate vertical plate that is mounted so that it can swing up and down. The mass of the swing member 120 is set to be smaller than the mass of the front slider 50 and the mass of the rear slider 110.

  The swing member 120 has a pin 121 (swing pin 121) at a swing tip portion. The swing pin 121 is arranged in parallel to the front pin 113, extends through the swing member 120 to both the left and right sides, and a portion extending to one side is covered with the buffer member 122. The buffer member 122 is made of an elastic pipe such as rubber. The swing pin 121 is fitted into the long hole 117 of the rear slider 110 via the buffer member 122. As a result, the swing member 120 can swing up and down within the range of the long hole 117. Hereinafter, the swing pin 121 will be described as “swing tip 121” as appropriate.

  As shown in FIGS. 2, 9, and 10, the fixing member 130 is disposed rearward of the front slider 50 when positioned at the fully closed position FSc (see FIG. 2) and forward of the rear slider 110. Arranged and attached to the right flange 22b. As a result, the fixing member 130 is fixed to the roof 11 via the left side frame member 22. The fixing member 130 is a vertical plate-like member, and has a locking groove 131 on a side surface facing the guide groove 22a.

  The overall shape of the locking groove 131 is generally arcuate when viewed from the side (vehicle width direction). That is, the locking groove 131 is a substantially arc-shaped groove opened so that one end 132 (rear end 132) faces the swing tip 121. More specifically, one end 132 of the locking groove 131 is open so that the swing tip 121 can enter and exit. The other end 133 (upper end 133) of the locking groove 131 has an open configuration or a closed configuration, and is disposed higher than the one end 132. The locking groove 131 includes a substantially horizontal lateral groove portion 134 that communicates with the opened one end 132, an arc-shaped corner groove portion 135 that communicates with the lateral groove portion 134 and extends upward while being curved, and the corner groove portion 135. It consists of a substantially longitudinal longitudinal groove 136 that communicates and extends to the other end 133. The swing member 120 can hang the swing tip 121 on the locking groove 131.

The urging member 141 is a member that urges the locking groove 131 in the direction Up (upward) in which the swing member 120 is hooked. Become.
As shown in FIG. 9, the combination structure of the swing member 120, the fixing member 130, and the urging member 141 constitutes a rear fully closed lock portion 161. The rear fully closed lock portion 161 locks the rear slider 110 so as to be kept in a stopped state at a predetermined rear panel fully closed position RSc (see FIG. 10B).

  As shown in FIGS. 9 and 10, the slider connecting portion 150 includes a connecting groove provided at the rear end portion of the lift guide plate 52 in the front slider 50. Hereinafter, the slider connecting portion 150 will be described as “connecting groove 150” as appropriate.

  The overall shape of the connecting groove 150 is generally an arch shape when viewed from the side (vehicle width direction), and is generally a shape that is vertically inverted with respect to the locking groove 131. That is, the connecting groove 150 is a substantially arc-shaped groove that is open so that one end 151 (rear end 151) faces the swing tip 121. More specifically, one end 151 of the connecting groove 150 is open so that the swing tip 121 can enter and exit. The other end 152 (lower end 152) of the connecting groove 150 is closed, and is disposed below the one end 151, and is set at the same height as the one end 132 and the lateral groove 134 of the locking groove 131. . The connecting groove 150 communicates with the substantially horizontal lateral groove portion 153 communicating with the open end 151, the arc-shaped corner groove portion 154 communicating with the lateral groove portion 153 and extending downward, and communicating with the corner groove portion 154. And a substantially longitudinal longitudinal groove portion 155 extending to the other end 152.

  Next, the interlocking relationship between the front slider 50 and the rear slider 110 will be described with reference to FIGS. 10 to 12 with reference to FIGS. In FIGS. 11 and 12, the configuration around the rear slider 110 is divided into (a), (b), and (c) in the same manner as in FIG. 10 to facilitate understanding of the description.

2 and 10 show the position RSc of the rear slider 110 when the rear panel 33 is located at the predetermined fully closed position RPc. Note that FIG. 10B corresponds to FIG.
In this state, since the swing member 120 is urged by the urging member 141, the swing tip 121 is fitted in the vertical groove 136 of the locking groove 131. That is, the swing tip 121 is in a state of being hooked on the locking groove 131 (locked state). For this reason, the rear fully closed lock portion 161 (see FIG. 9) locks the rear slider 110 so as to be kept stopped at a predetermined rear panel fully closed position RSc. The swing member 120 cannot move in the front-rear direction. In addition, the swing tip 121 is in contact with the upper end of the long hole 117, so that the upward swing is restricted. Hereinafter, the position Sro where the swing tip 121 is locked by being hooked on the vertical groove 136 of the locking groove 131 is referred to as “lock position Sro”.

  Thereafter, the front slider 50 slides in the opening direction (arrow Pr direction) from the fully closed position FSc, thereby reaching the position indicated by the imaginary line shown in FIG. 10C, that is, the lock position Sro. As a result, the swing tip 121 enters the one end 151 of the connecting groove 150. The state in which the front slider 50 is further slid in the opening direction thereafter is shown in FIGS.

3 and 11 show a state in which the front slider 50 has reached the predetermined half-open position FSh by sliding in the opening direction from the fully closed position Fsc. In addition, FIG.11 (b) respond | corresponds with FIG.3 (b), and FIG.11 (c) respond | corresponds with FIG.3 (c).
When the front slider 50 reaches the half-open position FSh, the front panel 32 also reaches the predetermined half-open position FPh. When the front slider 50 slides from the fully closed position Fsc to the half-open position FSh, the connecting groove 150 guides the swing tip 121 to be detached from the locking groove 131 and latches the guided swing tip 121. . That is, the swing member 120 swings downward to near the lower end of the long hole 117 against the urging force of the urging member 141.

  In other words, when the front slider 50 moves in the direction of the arrow Pr, the arc-shaped corner groove portion 154 in the connecting groove 150 guides the swing tip portion 121 downward. That is, the swing member 120 swings downward. As a result, the swing tip 121 is displaced from the horizontal groove 153 to the vertical groove 155 in the connecting groove 150. At the same time, the swing tip 121 is displaced from the vertical groove 136 to the horizontal groove 134 in the locking groove 131. Accordingly, the rear fully closed lock portion 161 is unlocked and the rear slider 110 is connected to the front slider 50. In this state, as shown in FIG. 11 (c), the swing tip 121 is slightly lower than the horizontal. Hereinafter, the position Sun in which the swing tip 121 is engaged with the lateral groove 134 of the locking groove 131 and unlocked is referred to as “unlock position Sun”.

  Thereafter, the front slider 50 further slides in the opening direction, whereby the front slider 50 slides and drives the rear slider 110 backward via the swing member 120 and the front pin 113. The result of the front slider 50 moving further in the opening direction is shown in FIG.

FIG. 12 shows a state in which the front slider 50 is further slid in the opening direction from the half-open position FSh (see FIG. 3). The swing tip 121 is pulled out from one end 132 of the locking groove 131. Thereafter, as shown in FIG. 4, the front slider 50 slides to the fully open position FSo, and the rear slider 110 also slides to the fully open position RSo.
When the front slider 50 stops at the fully open position FSo, the rear slider 110 also stops at the fully open position RSo. The swing tip 121 is maintained connected to the connecting groove 150.

  Thereafter, as shown in FIG. 4, when the front slider 50 returns from the fully open position FPo in the closing direction (arrow Pf direction), the rear slider 110 is pulled by the front slider 50 and slides forward as shown in FIG. . As a result, the swing tip 121 enters the one end 132 of the locking groove 131. In this way, the connecting groove 150 guides the swing tip 121 so as to enter the locking groove 131. The results are shown in FIGS.

  As shown in FIGS. 3 and 11, after that, the front slider 50 further slides in the closing direction, so that the rear slider 110 also slides in the closing direction. For this reason, the connecting groove 150 guides the swing tip 121 that has entered the locking groove 131 further forward. The swing tip 121 moves through the lateral groove 134 and advances to the corner groove 135. The swing tip 121 that has reached the corner groove 135 is guided further forward by the connecting groove 150. At this time, the swing tip 121 rises by the biasing force of the biasing member 141 while being guided by the corner groove 135. That is, the swing member 120 swings upward. When the swing member 120 swings by a certain swing angle, the swing tip 121 is positioned at one end 151 of the connection groove 150 and enters the vertical groove 136 in the lock groove 131. The results are shown in FIGS.

As shown in FIGS. 3 and 10, the swing tip 121 is disengaged from the connecting groove 150 and is also restricted (locked) by the locking groove 131. In other words, the locking groove 131 guides the swing tip 121 that has entered the locking groove 131 to move away from the connecting groove 150 and shift to the locked state.
As described above, when the front slider 50 moves from the fully open position FSo in the closing direction and returns to the half-open position FSh, the rear slider 110 is detached from the front slider 50, and the rear fully closed lock portion 161 is returned to the original locked state. Return. Thereafter, only the front slider 50 returns to the fully closed position FSc (see FIG. 2), and the front panel 32 is returned to the fully closed state.

  As shown in FIG. 9, the combined structure of the locking groove 131 and the connecting groove 150 forms a slider detaching portion 162. That is, the slider detaching portion 162 is configured to serve as both the locking groove 131 and the connecting groove 150. The slider detaching portion 162 separates the rear slider 110 from the front slider 50 when the front slider 50 moves from the fully open position FSo (see FIG. 4) in the closing direction and returns to the half-open position FSh (see FIG. 3). Then, the rear fully closed lock part 161 is returned to the original locked state.

The above description is summarized as follows (see FIGS. 2 to 4, 9, and 10).
When the front slider 50 retracts from the fully closed position FSC (see FIG. 2) to the half-open position FSh (see FIG. 3), the slider connecting portion 150 (connecting groove 150) releases the locked state of the rear fully closed locking portion 161. In addition, the rear slider 110 is connected to the front slider 50. As a result, the front slider 50 and the rear slider 110 can be moved back to the fully open positions FSo, RSo (see FIG. 4) in direct linkage. Therefore, the front panel 32 in the half-open state and the rear panel 33 in the fully-closed state can be directly linked to open to the fully open positions FPo and RPo.

  Thereafter, when the front slider 50 moves forward from the fully open position FSo (see FIG. 4) to the half-open position FSh (see FIG. 3), the slider detaching portion 162 detaches the rear slider 110 from the front slider 50 and locks the rear fully closed. The unit 161 is returned to the original locked state. As a result, the rear slider 110 is detached from the front slider 50 and stopped. Thereafter, only the front slider 50 further advances to the fully closed position FSc (see FIG. 2). Therefore, it is possible to close only the front panel 32 to the fully closed position FPc in a state where the fully closed rear panel 33 is stopped.

  As described above, since the vehicle sunroof device 30 is provided with the slider connecting portion 150 and the slider detaching portion 162, the rear slider 110 can be directly interlocked with the operation of the front slider 50 with good timing and can be released with good timing. it can. As a result, the front panel 32 and the rear panel 33 can be directly linked with good timing and can be released with good timing. Furthermore, regardless of the state of the wire cable 37 (see FIG. 1), the interlocking state between the front panel 32 and the rear panel 33 can be maintained in a more appropriate state over a long period of time. In addition, this can be achieved with a simple configuration in which the slider connecting portion 150 and the slider detaching portion 162 are provided.

  Further, as shown in FIG. 9, the slider coupling portion 150 has a simple configuration including only the coupling groove 150 provided in the front slider 50. In addition, the slider detachment portion 162 has a simple configuration that serves as both the connection groove 150 of the slider connection portion 150 and the locking groove 131 of the rear fully closed lock portion 161. For this reason, the interlocking state of the front panel 32 and the rear panel 33 can be maintained in a more appropriate state over a long period of time with a very simple configuration with a small number of parts.

  Furthermore, as shown in FIG. 10, the swing member 120 extending from the rear slider 110 toward the front slider 50, a substantially arc-shaped locking groove 131 opened so that one end 132 faces the swing tip 121, and one end The interlocking state between the front panel 32 and the rear panel 33 can be made more appropriate by an extremely simple configuration in which the substantially arc-shaped connecting groove 150 opened so that 151 faces the swing tip 121 is combined. Can be maintained for a long time.

  Furthermore, as shown in FIG. 10, the mass of the swing member 120 is set to be smaller than the mass of the front slider 50 and the mass of the rear slider 110. For this reason, when the front slider 50 is retracted from the fully closed position FSc (see FIG. 2), the connecting groove 150 first hits the swing member 120 that is stopped, and immediately after that, the swing member 120 is swung by the connecting groove 150. Then, the rear slider 110 is moved backward. Since the mass of the swing member 120 is small, the impact when the connecting groove 150 hits the swing member 120 can be small. For this reason, generation | occurrence | production of a collision sound can be suppressed.

Next, the relationship among the rear slider 110, the rear panel support stay 170, and the stopper member 180 in the left rear panel drive mechanism 39 will be described.
FIG. 13A shows the left rear panel drive mechanism 39 when the rear panel 33 is fully closed. FIG. 13B shows a process in which the rear panel 33 is opened. FIG. 13C shows the left rear panel drive mechanism 39 when the rear panel 33 has been lowered. FIG. 14 shows a main part around the rear panel support stay 170 and the stopper member 180.

  As shown in FIG. 13, when the rear panel drive mechanism 39 opens the fully closed rear panel 33, the rear end 33b of the rear panel 33 is moved to the inner surface 11b of the roof 11 at a time earlier than the front end 33a of the rear panel 33. In other words, the rear end 33b of the rear panel 33 is lowered and retracted along the inner surface 11b of the roof 11.

As shown in FIG. 9, FIG. 13 (a) and FIG. 14, the rear panel support stay 170 is formed of a longitudinally long flat plate and has a pair of front and rear cam grooves on the side surface of the front end portion 170a and the side surface of the rear end portion 170b. 171 and 172. The front and rear cam grooves 171 and 172 are long and narrow elongated holes, and penetrate the rear panel support stay 170 from side to side. Both ends in the longitudinal direction of these long holes 171 and 172 are closed.
The first cam groove 171 formed in the front end portion 170 a is fitted to the front pin 113 of the rear slider 110. The first cam groove 171 is guided by the front pin 113 (guide pin 113). A second cam groove 172 formed in the rear end portion 170 b is fitted to the rear pin 114 of the rear slider 110. The second cam groove 172 is guided by the rear pin 114 (guide pin 114).

As shown in FIG. 14, the first cam groove 171 includes a first horizontal groove portion 171a on a substantially horizontal front side, a first inclined groove portion 171b extending while curving backward from the rear end of the first horizontal groove portion 171a, The first vertical groove portion 171c extends from the rear end of the first inclined groove portion 171b while being curved upward, and is continuous.
The second cam groove 172 includes a second horizontal groove portion 172a on the substantially horizontal front side, a second inclined groove portion 172b extending from the rear end of the second horizontal groove portion 172a while curving backward, and a rear side of the second inclined groove portion 172b. It consists of a second vertical groove portion 172c that extends while curving upward from the end, and is continuous.

  The overall shapes and dimensions of the first cam groove 171 and the second cam groove 172 are substantially the same as each other, but are greatly different in the following points. The inclination angle θ1 of the first inclined groove 171b is set smaller than the inclination angle θ2 of the second inclined groove 172b. In the first cam groove 171, the curved corner portion between the rear end of the first inclined groove portion 171 b and the lower end of the first vertical groove portion 171 c is greatly curved with a radius rc. On the other hand, the corner portion of the second cam groove 172 is slightly curved.

  Further, as shown in FIGS. 9, 13A and 14, the rear panel support stay 170 is directed from the front end portion 170a toward the front panel 32 (particularly toward the rear end of the lift guide plate 52 in the front slider 50). And a stay extension 173 extending. The stay extension 173 has a pin 174 at the tip. The pin 174 is disposed in parallel with the front pin 113. Hereinafter, the pin 174 will be described as “the tip 174 of the stay extension 173” as appropriate.

  The stopper member 180 is disposed at a position in front of the rear panel 33 (position near the front panel 32) when in the fully closed state, and is attached to the left flange 22b. As a result, the stopper member 180 is fixed to the roof 11 via the left side frame member 22. That is, the stopper member 180 is provided such that its movement is restricted with respect to the roof 11. The stopper member 180 is a plate-like member, and has a guide groove 181 on a side surface facing the guide groove 22a. The guide groove 181 is a groove for hooking and guiding the distal end portion 174 of the stay extension 173.

  As shown in FIG. 14, the overall shape of the guide groove 181 is generally a bow shape when viewed from the side (vehicle width direction). That is, the guide groove 181 is a substantially arc-shaped groove that is open so that one end 182 (rear end 182) faces the front end 174. More specifically, one end 182 of the guide groove 181 is open so that the front end 174 can enter and exit when the front end 33a of the rear panel 33 is lowered. The other end 183 (upper end 183) of the guide groove 181 is disposed higher than the one end 182 of the guide groove 181, and restricts the tip 174 from rising when the rear panel 33 (see FIG. 2) is fully closed. To be closed.

  The guide groove 181 communicates with the substantially horizontal lateral groove portion 184 communicated with the opened one end 182, an arcuate corner groove portion 185 communicating with the lateral groove portion 184 and extending upward, and communicated with the corner groove portion 185. And a substantially longitudinal longitudinal groove portion 186 extending to the other end 183. The corner groove portion 185 is set such that the lower half radius r1 connected to the horizontal groove portion 184 is large and the lower half radius r2 connected to the vertical groove portion 186 is small.

  As shown in FIGS. 13 and 14, the combined structure of the front pin 113 and the first cam groove 171 forms a first rear stay interlocking portion 191. Further, the combination structure of the rear pin 114 and the second cam groove 172 forms a second rear stay interlocking portion 192. The first and second rear stay interlocking portions 191 and 192 are interlocked so that the rear panel support stay 170 is retracted while being lowered in accordance with the backward movement of the rear slider 110.

  The combined structure of the stay extension 173 and the stopper member 180 forms a restricting portion 193. When the rear end portion 170b of the rear panel support stay 170 is lowered and retracted, the regulating portion 193 moves backward while the front end portion 170a of the rear panel support stay 170 is lowered, behind the rear end portion 170b of the rear panel support stay 170. It regulates to do. Further, the restricting portion 193 restricts the swing upper limit of the stay extension portion 173.

Next, the operational relationship among the rear slider 110, the rear panel support stay 170, and the stopper member 180 will be described (see FIGS. 13 and 14).
As shown in FIGS. 13A and 14, when the rear panel 33 is fully closed, the front pin 113 of the rear slider 110 is fitted in the first lateral groove 171 a of the first cam groove 171. Further, the rear pin 114 of the rear slider 110 is fitted in the second lateral groove portion 172 a of the second cam groove 172. Further, the front end portion 174 of the rear panel support stay 170 is fitted into the vertical groove portion 186 of the guide groove 181 and the upward swing is restricted by the closed other end 183 (closed end 183).

  Thereafter, by moving the rear slider 110 rearward, the front pin 113 and the rear pin 114 also move rearward. The inclination angle θ1 of the first inclined groove 171b is set smaller than the inclination angle θ2 of the second inclined groove 172b. For this reason, as the rear slider 110 moves rearward, the rear panel support stay 170 is guided by the front and rear pins 113 and 114, and the rear end portion 170b tends to retreat while descending before the front end portion 170a. In addition, the restricting portion 193 restricts the front end portion 170a to be retracted while being lowered later than the rear end portion 170b.

For this reason, when the rear slider 110 moves rearward, the rear end portion 170b moves backward while descending below the roof 11 before the front end portion 170a. Therefore, as shown in FIG. 13B, when the fully closed rear panel 33 is opened, the rear end 33b of the rear panel 33 is lowered before the front end 33a of the rear panel 33.
Further, since the upward swing of the front end portion 174 of the rear panel support stay 170 is restricted by the restriction portion 193, the front end portion 33a of the rear panel 33 rises when the rear end portion 33b of the rear panel 33 descends. There is nothing.
Then, as shown in FIG. 13C, the rear panel 33 is lowered to the inner surface 11 b of the roof 11. At this time, the rear end portion 33 b of the rear panel 33 is in a state of entering the rear of the rear edge of the roof opening 12.

  In the state where the lowering is completed, the front and rear pins 113 and 114 of the rear slider 110 are fitted into the vertical groove portions 171c and 172c (see FIG. 14) of the first and second cam grooves 171 and 172, respectively. Further, the front end portion 174 of the rear panel support stay 170 comes out of one end 182 of the guide groove 181.

  As the rear slider 110 further moves rearward, the rear panel support stay 170 also moves rearward. As a result, the rear panel 33 moves rearward along the inner surface 11b of the roof 11 and opens.

  Thereafter, by moving the rear slider 110 forward, the rear panel support stay 170 also moves forward. As a result, the rear panel 33 moves forward along the inner surface 11b of the roof 11 and returns to the state shown in FIG. That is, the rear panel 33 is in a state in which only the rear end portion 33 b enters rearward from the rear edge of the roof opening 12. At this time, the front end 174 of the rear panel support stay 170 enters one end 182 of the guide groove 181.

  As the rear slider 110 moves further forward, the front end portion 174 of the rear panel support stay 170 is guided by the guide groove 181 and moves forward and upward. At this time, the rear panel support stay 170 is guided by the front and rear pins 113 and 114, and moves forward while the front end 170a rises before the rear end 170b. Accordingly, as shown in FIG. 13B, when the rear panel 33 is closed, the front end portion 33a rises before the rear end portion 33b. As a result of completion of the raising of the rear panel 33, the rear panel 33 returns to the fully closed state of FIG.

The above description is summarized as follows.
As shown in FIG. 13, when the fully closed rear panel 33 is opened, the rear panel drive mechanism 39 lowers the rear end 33 b of the rear panel 33 to the inner surface 11 b of the roof 11 before the front end 33 a of the rear panel 33. Can be made. Therefore, the rear end 33b of the rear panel 33 can be lowered along the inner surface 11b of the roof 11. As a result, the timing at which the rear panel 33 moves backward can be advanced. Therefore, the rear end portion 33b of the rear panel 33 can be inserted into the inner surface 11b of the roof 11 in a shorter time than in the conventional case where the entire rear panel 33 is once lowered and then retracted. Furthermore, when the rear end portion 33b of the rear panel 33 is lowered, the front end portion 33a of the rear panel 33 can be restricted by the restriction portion 193.

  In this way, the rear end 33b of the rear panel 33 is allowed to enter the inner surface 11b of the roof 11 in a short time, and the front end 33a of the rear panel 33 is regulated so as not to rise, whereby the front panel 32 and the rear panel 33 are mutually connected. The roof opening 12 can be opened and closed quickly and without interference.

  In other words, when the fully closed rear panel 33 moves backward along the inner surface 11b of the roof 11, the restricting portion 193 (panel front end rising restricting portion 193) restricts the front end portion 33a of the rear panel 33 from rising. The rear end 33b of the rear panel 33 can be lowered. Since the front end portion 33a does not rise when the rear end portion 33b is lowered, there is no fear of hitting the rear panel 33 even if the front panel 32 is retracted accordingly. It is only necessary to start opening the rear panel 33 when the retracted front panel 32 approaches the front end portion 33a of the rear panel 33. That is, the timing at which the rear panel 33 starts to open can be delayed by the amount that the front end 33a of the rear panel 33 does not rise. By delaying the opening start timing, the front panel 32 and the rear panel 33 can simultaneously reach the fully opened position. Since both the front panel 32 and the rear panel 33 can be fully opened, the large roof opening 12 can be opened widely. As a result, the opening amount when the sunroof panel 31 is fully opened increases.

  Further, the rear panel includes a restriction portion 193 having a simple structure including a combination of a stay extension portion 173 provided on the rear panel support stay 170 that supports the rear panel 33 and a stopper member 180 that restricts the swing upper limit of the stay extension portion 173. The front end portion 33a of 33 can be reliably regulated so as not to rise.

  Moreover, since the stopper member 180 is provided in a position in front of the rear panel 33 when the stopper member 180 is in the fully closed state, the movement of the stopper member 180 is restricted with respect to the roof 11, so that the front end portion 33a of the rear panel 33 rises. It is possible to regulate more reliably.

  Furthermore, when the rear panel 33 is in the fully closed state, the stopper member 180 restricts the swing upper limit of the stay extension 173 and also restricts the front and rear slides of the stay extension 173, and the front end 33a of the rear panel 33 is lowered. In this state, the stay extension portion 173 is configured to allow sliding back and forth.

Therefore, when the rear panel 33 is in the fully closed state, the stay extension portion 173 is restricted by the stopper member 180 from the swing upper limit and the front / rear slide. For this reason, the front end 33a of the rear panel 33 can be reliably maintained in the fully closed state.
On the other hand, when the front end 33a of the rear panel 33 is in the lowered state, the stay extension 173 can freely slide back and forth. For this reason, the roof opening 12 can be smoothly opened and closed by sliding the rear panel 33 back and forth.

  Furthermore, the stopper member 180 has a substantially arc-shaped guide groove 181 for guiding the tip 174 of the stay extension 173. The substantially arc-shaped guide groove 181 has a closed other end 183 (closed end 183) disposed higher than an open end 182 (open end 182). For this reason, when the rear panel 33 is in the fully closed state, the leading end 174 is restricted from rising and sliding forward and backward by the closed end 183. When the front end portion 33 a of the rear panel 33 is in the lowered state, the front end portion 174 can freely enter and exit from the open end 182. The rear panel 33 protruding from the open end 182 can be slid back and forth along the inner surface 11 b of the roof 11. Furthermore, the substantially arcuate guide groove 181 allows the tip 174 to be moved very smoothly between the closed end 183 at the upper limit position and the open end 182 at the lower limit position.

  As described above, the opening / closing operation of the front end portion 33a of the rear panel 33 can be smoothly performed with only a very simple configuration in which the tip end portion 174 of the stay extension portion 173 is guided by the substantially arc-shaped guide groove 181 whose upper end is closed. Can be done.

  Furthermore, as described above, when the fully closed rear panel 33 is opened, the rear end portion 33b is lowered before the front end portion 33a and is retracted along the inner surface 11b of the roof 11. For this reason, as shown in FIG. 13B, the rear end portion 33b of the fully closed rear panel 33 starts from the descent start time Ts when the descent starts to the descent completion time Te that enters the inner surface 11b of the roof 11. The trailing edge lowering time Tmd can be shortened. That is, the rear end portion 33b of the rear panel 33 can be inserted into the inner surface 11b of the roof 11 in a shorter time than in the conventional case where the entire rear panel 33 is once lowered and then retracted.

  When the lowering speed of the rear panel 33 is reduced in order to reduce the burden on the electric motor 35, the lowering time of the rear panel 33 becomes longer, but this can be compensated for by reducing the rear end lowering time Tmd. . That is, when considering the descent completion time Te as a reference, the descent start time Ts can be delayed by the amount by which the rear end descent time Tmd is shortened. Therefore, even if the lowering start timing of the rear panel 33 is not advanced, there is no fear that the front panel 32 being retracted will hit the rear panel 33 being lowered.

  Further, since the lowering start timing of the rear panel 33 is not advanced, the timing at which the rear panel 33 reaches the fully open position RPo is not accelerated. When the rear panel 33 reaches the fully open position RPo, the front panel 32 also reaches the fully open position FPo. Since both the front panel 32 and the rear panel 33 can be fully opened, even the large roof opening 12 can be opened widely. As a result, the amount of opening when the sunroof panel 31 is fully opened increases, which increases the feeling of opening and refreshing for the occupant.

  Moreover, despite the large roof opening 12, it can be quickly and reliably opened and closed between the fully open state and the fully closed state. Furthermore, since the lowering speed and the rising speed of the rear panel 33 can be reduced, the burden on the electric motor 35 can be suppressed.

Further, the rear panel 33 is quickly and surely lowered and retracted by the rear panel drive mechanism 39 having a simple configuration including a combination of the rear slider 110, the rear panel support stay 170, the rear stay interlocking portions 191, 192, and the restriction portion 193. be able to.
Furthermore, the rear panel support stay 170 is lowered while being lowered by the rear stay interlocking portions 191 and 192 having a very simple configuration including the guide pins 113 and 114 and the cam grooves 171 and 172 in accordance with the backward movement of the rear slider 110. Can be linked to
Further, the front end portion 170a of the rear panel support stay 170 is moved backward while being lowered with respect to the rear end portion 170b by the restricting portion 193 having a very simple configuration including the guide groove 181 and the extension portion 173 of the stopper member 180. be able to.
