  By the way, in patent document 1, since it is the structure which controls a movement of a 2nd sliding member etc. by engaging the engagement protrusion of a check in the engagement groove of a guide block, it is within the tolerance of a check or a guide block. There is a possibility that the check on the guide block may rattle in the front-rear direction of the vehicle due to product variations and assembly variations in the vehicle. In this case, there is a possibility that the second sliding member connected to the check rattles in the front-rear direction of the vehicle together with the movable panel.

  The objective of this invention is providing the sunroof apparatus which can suppress the shaki of the movable panel to the front-back direction of a vehicle.

  A sunroof device that solves the above problems is connected to a guide rail provided at each edge in the vehicle width direction of an opening formed in the roof of the vehicle, and to each edge in the vehicle width direction of a movable panel that opens and closes the opening. A sliding member driven to move along the guide rail by an electric drive source; an engagement groove; a guide block provided in the guide rail; and the guide integrally formed with the movable panel. A second sliding member that is movable along the rail, and an engaging protrusion that can be engaged with the engaging groove and connected to the second sliding member, and the movable panel is fully closed. Then, when the engaging protrusion engages with the engaging groove and the sliding member moves forward of the vehicle, the movement of the second sliding member is restricted, and the sliding member further includes the vehicle. When moving to the rear of the vehicle after moving forward And a check for releasing the movement restriction of the second sliding member when the engaging protrusion moves out of the engaging groove, and the sliding member moves forward of the vehicle in the fully closed state. In the tilt-up state, and in the tilt-up state, the tilt-up state is maintained by engaging the second sliding member when the vehicle further moves forward and then moves rearward of the vehicle. A pressure contact surface and a pressure contact surface that are in pressure contact with each other in the state of movement restriction are formed on opposing surfaces of the guide block and the second sliding member in the width direction of the vehicle, respectively.

  According to this configuration, the movement of the second sliding member is restricted together with the movable panel when the engaging protrusion of the check is engaged in the engaging groove of the guide block. At this time, the pressure contact surface and the pressure contact surface of the guide block and the second sliding member are in a pressure contact state. Therefore, even if the check or the check block rattles in the front-rear direction of the vehicle due to product variations or assembly variations of the guide block, the static friction force generated between the pressure contact surface and the pressure contact surface The backlash of the second sliding member in the front-rear direction of the vehicle, and consequently the backlash of the movable panel connected to the second sliding member in the front-rear direction of the vehicle can be suppressed.

  In the sunroof device, the pressure contact surface is formed on a block side protruding portion protruding from the guide block in the width direction of the vehicle toward the second sliding member, and toward the guide block. It is preferable that the pressure contact surface is formed at a sliding member side protruding portion protruding from the second sliding member in the vehicle width direction.

  According to this configuration, the pressure contact surface is formed on the block side protrusion, or the pressure contact surface is formed on the sliding member side protrusion, so that the dimension of the corresponding protrusion in the longitudinal direction of the vehicle. By changing the above, it is possible to easily adjust the static friction force generated between the pressure contact surface and the pressure contact surface.

  With respect to the sunroof device, at least one of the guide block and the second sliding member may be configured such that the pressure contact surface and the pressure contact when the second sliding member moves forward of the vehicle with respect to the guide block. It is preferable to have a guide portion for guiding the pressure contact of the surface.

  According to this configuration, when the second sliding member moves to the front of the vehicle with respect to the guide block, that is, when the movable panel is closed while being tilted up, the guide portion causes the cover to be covered. The pressure contact surface and the pressure contact state of the pressure contact surface can be shifted more smoothly.

  In the sunroof device, the check is rotatably connected to the second sliding member around an axis extending in the front-rear direction of the vehicle, and in the fully closed state, the engagement protrusion is the engagement groove. And when the sliding member moves forward of the vehicle, the movement of the second sliding member is restricted and shifted to the tilt-up state. Further, rotation is allowed when moving forward of the vehicle, and then when the sliding member moves rearward of the vehicle, it is guided to rotate so that the engaging protrusion is removed from the engaging groove. The movement restriction of the second sliding member is released, and when the sliding member moves forward of the vehicle in the open state of the movable panel, the engagement protrusion engages with the engagement groove. When the sliding member is further guided forward and moved further forward of the vehicle Is preferably a rotary check for restricting the movement of said second sliding member.

  According to this configuration, since the engagement protrusion is engaged with the engagement groove according to the movement restriction of the second sliding member and the like by the rotation operation of the rotation check. It becomes difficult to secure a surface for suppressing backlash in the longitudinal direction of the vehicle between the groove and the engaging protrusion. For this reason, it becomes more effective to suppress the shakiness of the movable panel in the front-rear direction of the vehicle using the static friction force generated between the pressure contact surface and the pressure contact surface.

  The present invention has an effect of suppressing rattling of the movable panel in the front-rear direction of the vehicle.

  Hereinafter, an embodiment of the sunroof device will be described. Hereinafter, the front-rear direction of the vehicle is referred to as “front-rear direction”, and the upper direction and the lower direction of the vehicle height are referred to as “upward” and “lower”, respectively. Further, the inside in the width direction of the vehicle heading toward the inside of the vehicle interior is referred to as “vehicle inside”, and the outside in the width direction of the vehicle toward the outside of the vehicle interior is referred to as “vehicle outside”.

  As shown in FIG. 6, a substantially square opening 10 a is formed in a roof 10 of a vehicle such as an automobile, and a sunroof device 11 is mounted. The sunroof device 11 includes a substantially rectangular movable panel 12 made of, for example, a glass plate that moves in the front-rear direction to open and close the opening 10a.

  The movable panel 12 is attached so that a tilt-up operation in which the rear part rises with the front part as a fulcrum and a slide operation in the front-rear direction. In the opening / closing operation of the opening 10a by the movable panel 12, a so-called outer sliding type is employed in which the sliding operation is performed in the tilt-up state.

Next, the structure of the sunroof device 11 related to the opening / closing operation of the movable panel 12 will be described.
As shown in FIG. 7, a pair of guide rails 13 is disposed at both edges of the opening 10 a in the width direction of the vehicle. Each guide rail 13 is made of, for example, an extruded material of an aluminum alloy, has a constant cross section in the longitudinal direction, and extends in the front-rear direction. Each guide rail 13 supports and supports the functional component 20 so as to be movable in the front-rear direction. The movable panel 12 is linked to and supported by both functional parts 20 in a state of being bridged between them. The two functional components 20 cause the movable panel 12 to perform a tilt-up operation or a slide operation in accordance with the movement in the front-rear direction along the guide rail 13.

  The front ends of both guide rails 13 are connected via a front housing 14 that extends in the vehicle width direction. A motor 15 as an electric drive source having an output gear, for example, is installed in the longitudinal intermediate portion of the front housing 14. The motor 15 is connected to each functional component 20 through each of a pair of substantially belt-like drive belts 16 made of, for example, a resin material, and simultaneously moves both functional components 20 in the front-rear direction.

  As shown in FIGS. 3 (a) and 3 (b), each guide rail 13 is formed with a first rail portion 13a having a substantially C-shaped cross section that opens upward, and the vehicle of the first rail portion 13a. A second rail portion 13b is formed adjacent to the outside. The second rail portion 13b has a substantially T-shaped cross section in cooperation with the side wall of the first rail portion 13a, and communicates with the first rail portion 13a through an opening formed in the side wall. Each guide rail 13 is formed with a flange 17 above the vehicle outer side portion of the first rail portion 13a.

  As shown in FIG. 4, the flange 17 is formed with a substantially rectangular notch 17a at a predetermined position near the front of the vehicle. A guide block 60 is fixed to the guide rail 13. The guide block 60 is mounted on the outer side of the first rail portion 13 a and is fitted to the flange 17 in the notch 17 a. The guide block 60 is formed with an engagement groove 60 a that communicates from above to below the flange 17. That is, the engagement groove 60a is inclined downward toward the rear of the vehicle, and communicates below the flange 17 at its lower end.

  Further, as shown in FIGS. 1 and 3A, the front end portion of the guide block 60 is substantially protruded inward of the vehicle at a position sandwiched between the first rail portion 13a and the flange 17 in the height direction of the vehicle. Block-shaped block-side protrusions 61 are formed. The block-side protruding portion 61 protrudes further toward the vehicle inner side than the upper wall of the first rail portion 13a within the range of the flange 17, and the front end surface (vehicle inner side surface) that spreads in a substantially planar shape forms the pressure contact surface 61a. Form.

  As shown in FIG. 1, a drive shoe 21 as a sliding member in which, for example, a metal plate and a resin are integrated is mounted on the guide rail 13 (first rail portion 13a) so as to be movable in the front-rear direction. The drive shoe 21 is provided with a vertical wall portion 22 standing substantially over the entire length in the front-rear direction, and a substantially constant distance from the lower end portion of the vertical wall portion 22 to the vehicle outer side over the entire length in the front-rear direction. The protruding wall portion 23 is raised. The drive shoe 21 has a plurality (three) of extended pieces 24 that enter the second rail portion 13b on the vehicle exterior side. These extending pieces 24 are connected to the drive belt 16 that slides in the front-rear direction on the second rail portion 13b. The drive shoe 21 is moved in the front-rear direction along the first rail portion 13a by the motor 15 moving the drive belt 16 in the front-rear direction along the guide rail 13 (second rail portion 13b).

  As shown in FIGS. 2 (a) and 2 (b), the vertical wall portion 22 is formed with a guide groove 22a that is recessed from the vehicle outer end surface toward the vehicle inner side in the front-rear direction. The guide groove 22a is basically inclined so as to go upward as it goes rearward. Further, as shown in FIG. 3B, an engaging recess 26 that is recessed from the vehicle outer end surface toward the vehicle inner side is formed in the middle portion in the longitudinal direction of the protruding wall portion 23. The rear end surface of the engaging recess 26 forms a restricting portion 26a.

  On the other hand, as shown in FIG. 1, a support bracket 31 extending in the front-rear direction is fixed to the lower surface of the movable panel 12 at each edge in the width direction of the vehicle. The support bracket 31 extends over substantially the entire length of the movable panel 12 and has a vertical wall portion 32 made of a metal plate suspended from the lower surface of the movable panel 12. It has a resin-made molded portion 33 mainly embedding the lower edge portion.

  The support bracket 31 is arranged in parallel on the vehicle outer side of the vertical wall portion 22 so as to be basically disposed above the protruding wall portion 23 of the drive shoe 21. A mounting piece 31a bent toward the vehicle interior is formed at the front end of the support bracket 31, and a substantially cylindrical follower shoe 34 is formed at the tip of the mounting piece 31a. The driven shoe 34 is attached to the first rail portion 13a of the guide rail 13 so as to be movable in the front-rear direction in front of the drive shoe 21 in the vehicle. The movable panel 12 performs a tilt-up operation, for example, by rotating the support bracket 31 so that the rear part rises with the front part (driven shoe 34) as a fulcrum, and the rear part descends with the front part as a fulcrum. Tilt-down operation is performed by rotating to do. The drive shoe 21 and the driven shoe 34 constitute the functional component 20.

  As shown in FIG. 2 (a), a substantially cylindrical lifting guide pin 35 is integrally provided at the front end portion of the molding portion 33 so as to protrude into the vehicle interior and be movably fitted into the guide groove 22a. ing. The elevating guide pin 35 is set to be disposed at the lower end of the guide groove 22a when the movable panel 12 is fully closed. Accordingly, in this state, when the drive shoe 21 moves a predetermined distance forward of the vehicle with respect to the support bracket 31, the elevating guide pin 35 goes up the guide groove 22a and reaches the intermediate portion thereof. At this time, the movable bracket 12 performs a tilt-up operation by rotating the support bracket 31 so that the rear part rises with the front part as a fulcrum (first tilt-up state).

  Subsequently, when the drive shoe 21 further moves forward of the vehicle along the guide rail 13 (first rail portion 13a), as shown in FIG. 2 (b), the elevating guide pin 35 further moves up the guide groove 22a. Reaching its end. At this time, the movable bracket 12 further performs a tilt-up operation (second tilt-up state) by rotating the support bracket 31 so that the rear part is further raised with the front part as a fulcrum.

Note that a substantially long cylindrical locking pin 36 that protrudes outward from the vehicle is integrally provided at the front end of the molding portion 33 that is in front of the vehicle with respect to the lifting guide pin 35.
As shown in FIG. 1, the guide rail 13 (first rail portion 13 a) has a slide check 41 as a second sliding member made of, for example, a resin material adjacent to the outside of the support bracket 31 in the front-rear direction. It is mounted so as to be movable. That is, as shown in FIG. 3A, the slide check 41 has a shoe portion 42 that slides on the vehicle outer side of the first rail portion 13a, and between the support bracket 31 and the flange 17 in the vehicle width direction. It has the vertical wall part 43 standing upright. The slide check 41 slides the shoe portion 42 on the vehicle outer side portion of the first rail portion 13a in a state where the slide check 41 is positioned in the vehicle width direction by the support bracket 31 and the flange 17 that are in contact with or close to the vertical wall portion 43. Thus, it is movable in the front-rear direction along the guide rail 13.

  Further, the slide check 41 bulges a substantially step-shaped guide wall portion 44 from the lower end portion of the vertical wall portion 43 to the vehicle outer side over substantially the entire length in the front-rear direction. The slide check 41 is restricted from moving upward by contacting or approaching the lower surface of the flange 17 in the guide wall portion 44. In addition, the front end surface (vehicle outer side surface) spreading in a substantially flat shape at the front end portion of the guide wall portion 44 forms a pressure contact surface 44a. In the slide check 41 and the guide block 60, for example, when the movable panel 12 is fully closed, the pressure contact surface 44a and the pressure contact surface 61a are in pressure contact. That is, the pressure contact surface 61a and the pressure contact surface 44a are, for example, in the vehicle width direction of the block side protruding portion 61 (guide block 60) and the guide wall portion 44 (slide check 41) when the movable panel 12 is in the fully closed state. Each is formed on the opposing surface. In other words, in a state where the slide check 41 is separated from the guide block 60 toward the rear of the vehicle, the slide check 41 and the guide block 60 positioned in the vehicle width direction with respect to the guide rail 13 as described above. Is set so that the position in the width direction of the vehicle slightly overlaps at the front end portion of the guide wall portion 44 and the block side protruding portion 61.

  As shown in FIGS. 2A and 2B, a long hole-like allowable hole 43 a into which the locking pin 36 is movably fitted is formed at the front end portion of the vertical wall portion 43. The permissible hole 43a is inclined linearly so as to go upward as it goes rearward of the vehicle. That is, the slide check 41 is coupled to the support bracket 31 via the locking pin 36 that is fitted into the allowable hole 43a. The slide check 41 allows the movable panel 12 to be tilted (tilt-up operation or tilt-down operation) by causing the locking pin 36 to run idle in the allowable hole 43a. Further, the slide check 41 restricts the movement of the locking pin 36 (support bracket 31) in the front-rear direction at the allowance hole 43a when the tilting operation of the movable panel 12 is restricted. Therefore, the slide check 41 moves in the front-rear direction, thereby moving the movable panel 12 supported by the support bracket 31 integrally in the front-rear direction (sliding operation).

  The slide check 41 is provided with a substantially columnar support shaft 45 extending in the front-rear direction so as to be unable to rotate toward the rear of the vehicle. A substantially annular rotation check 46 as a check is pivotally supported at the front end of the support shaft 45 adjacent to the slide check 41. As shown in FIG. 3B, the rotation check 46 has a substantially serrated engagement protrusion 46a that protrudes radially outward at a predetermined angular position (the right-pointing angular position in the figure) with the support shaft 45 as the center. And a substantially triangular tooth-shaped pressed portion 46b that protrudes radially outward at a predetermined angular position (leftward-facing angular position in the figure) with the support shaft 45 as the center. Then, as illustrated by a two-dot chain line in FIG. 3B, the rotation check 46 is configured such that, for example, when the movable panel 12 is fully closed, the engagement protrusion 46 a is engaged with the guide block 60 above the flange 17. While being engaged with the groove 60a, the pressed portion 46b abuts or approaches the bottom surface of the first rail portion 13a and the vehicle outer surface of the protruding wall portion 23. Therefore, when the movable panel 12 is fully closed, the rotation check 46 is restricted by the bottom surface of the first rail portion 13a and the like with the engagement protrusion 46a engaging with the engagement groove 60a of the guide block 60. ing. Accordingly, the movement of the rotation check 46 in the front-rear direction is restricted, and the movement of the slide check 41 in the front-rear direction together with the rotation check 46 is restricted. The movement of the support bracket 31 connected to the slide check 41 via the allowance hole 43a and the like in the front-rear direction is also restricted, so that the movable panel 12 is only allowed to transition from the fully closed state to the tilted-up state. The The guide block 60, the slide check 41, the rotation check 46, and the like constitute a check mechanism 40.

  As described above, the engaging recess 26 is formed in the protruding wall portion 23 of the drive shoe 21. When the engagement recess 26 reaches the pressed portion 46b as the drive shoe 21 moves forward of the vehicle, the rotation check 46 is allowed to rotate within the engagement recess 26. Therefore, in this state, when the rotation check 46 is moved to the rear of the vehicle together with the drive shoe 21, the rotation check 46 is guided in the engagement groove 60a by the engagement protrusion 46a, as shown in FIG. Rotate clockwise as drawn by the solid line. Then, the engaging protrusion 46a enters below the flange 17 so as to be sandwiched between the first rail portion 13a. Thereby, the rotation of the rotation check 46 is restricted. At the same time, the pressed portion 46 b is engaged with the engagement recess 26. At this time, the pressed portion 46b is disposed on the movement locus in the front-rear direction of the restricting portion 26a of the drive shoe 21.

  As shown in FIG. 2A, a rotating cam 51 made of, for example, a resin material is pivotally supported at the rear end portion of the support shaft 45. On the other hand, a fixed cam 52 made of, for example, a resin material is installed on the drive shoe 21 so as to be coaxial with the rotating cam 51 behind the vehicle. The fixed cam 52 is separated from the rotary cam 51 at the position of the drive shoe 21 corresponding to at least the time when the movable panel 12 shifts from the fully closed state to the first tilt-up state. Further, as shown in FIG. 2B, the fixed cam 52 has a position in the front-rear direction relative to the rotary cam 51 at the position of the drive shoe 21 corresponding to when the movable panel 12 shifts to the second tilt-up state. overlapping. The rotating cam 51 and the fixed cam 52 constitute a known engagement / disengagement switching mechanism 50. The engagement / disengagement switching mechanism 50 switches from the disengaged state of the rotating cam 51 and the fixed cam 52 from the disengaged state to the engaged state by the pressing action between the rotating cam 51 and the fixed cam 52, or the rotating cam 51 and the fixed cam 52. Is switched from the engaged state to the disengaged state.

  With such a configuration, for example, when the drive shoe 21 moves to the front of the vehicle by the predetermined distance with respect to the support bracket 31 in the fully closed state of the movable panel 12, the locking pin 36 allows the slide check 41 to be allowed. The allowance hole 43a runs idly so as to rise along the hole 43a, and the elevating guide pin 35 goes up the guide groove 22a and reaches the intermediate portion thereof. Along with this, the movable panel 12 shifts to the first tilt-up state.

  As described above, at the position of the drive shoe 21 corresponding to when the movable panel 12 shifts from the fully closed state to the first tilt-up state, the rotating cam 51 and the fixed cam 52 of the engagement / disengagement switching mechanism 50 are They are separated in the front-rear direction (disengaged state of the rotating cam 51 and the fixed cam 52). Accordingly, when the drive shoe 21 moves rearward in the first tilt-up state of the movable panel 12, the allowance hole 43a is emptied so that the locking pin 36 descends along the allowance hole 43a of the slide check 41. At the same time, the elevating guide pin 35 moves down the guide groove 22a and reaches its end. Accordingly, the movable panel 12 performs a tilt-down operation in which the rear part descends with the front part of the support bracket 31 as a fulcrum, and shifts to the fully closed state.

  On the other hand, when the drive shoe 21 further moves forward of the vehicle with respect to the support bracket 31 in the first tilt-up state of the movable panel 12, the locking pin 36 further rises along the allowable hole 43 a of the slide check 41. Thus, the elevating guide pin 35 goes up the guide groove 22a and reaches its end. Along with this, the movable panel 12 shifts to the second tilt-up state. Further, as the driving shoe 21 moves forward of the vehicle, the engaging recess 26 reaches the pressed portion 46b, whereby the rotation check 46 is allowed to rotate.

  At this time, as described above, the rotation cam 51 and the fixed cam 52 of the engagement / disengagement switching mechanism 50 overlap in the front-rear direction. Therefore, after that, when the drive shoe 21 moves to the rear of the vehicle together with the fixed cam 52, the slide check 41 together with the rotary cam 51 is switched along with the switching to the engaged state by the pressing action between the rotary cam 51 and the fixed cam 52. And the rotation check 46 tries to move to the rear of the vehicle. Accordingly, the rotation check 46 that is allowed to rotate in the engagement recess 26 is guided by the engagement groove 46a so that the engagement protrusion 46a is positioned below the flange 17. Rotate to enter. The rotation check 46 is restricted in this state. Thereby, the restriction | limiting of the movement to the back of the vehicle of the slide check 41 is cancelled | released, and the movement limitation to the rear of the vehicle of the support bracket 31 connected with this slide check 41 via the allowance hole 43a etc. is also cancelled | released. At the same time, the pressed portion 46b enters the engaging recess 26 and is disposed on the movement locus in the front-rear direction of the restricting portion 26a.

  Therefore, when the drive shoe 21 moves to the rear of the vehicle, the slide check 41 moves to the rear of the vehicle together with the support bracket 31 and the rotation check 46 through the rotating cam 51 and the fixed cam 52 in the engaged state. At this time, the movable panel 12 supported by the support bracket 31 moves to the rear of the vehicle in the second tilt-up state to open the opening 10a. Thereby, the movable panel 12 will be in an open state.

  When the movable panel 12 is in the open state, the rotation check 46 is restricted in a state in which the engagement protrusion 46 a enters below the flange 17 as described above. And the to-be-pressed part 46b is arrange | positioned on the movement locus | trajectory in the front-back direction of the control part 26a. Accordingly, in this state, when the drive shoe 21 moves to the front of the vehicle, the restricting portion 26a presses the pressed portion 46b, so that the rotation check 46 moves together with the slide check 41 and the support bracket 31 to the front of the vehicle. To do. At this time, the movable panel 12 supported by the support bracket 31 moves to the front of the vehicle in the second tilt-up state, and closes the opening 10a.

  As the movable panel 12 closes, when the movable panel 12 approaches the initial state in which the movable panel 12 has shifted to the second tilt-up state, the rotation check 46 causes the engagement protrusion 46a to be guided to the engagement groove 60a. Thus, the engaging protrusion 46 a is rotated so as to enter above the flange 17 while removing the pressed portion 46 b from the engaging recess 26. Thereby, the movement of the rotation check 46 in the front-rear direction is restricted together with the slide check 41 and the support bracket 31. At this time, when the front end portion of the guide wall portion 44 reaches the block side protruding portion 61, the pressure contact surface 44a and the pressure contact surface 61a are in a pressure contact state.

  In this state, when the drive shoe 21 further moves forward of the vehicle, the fixed cam 52 further moves forward of the vehicle with respect to the rotary cam 51 whose movement in the front-rear direction is restricted together with the slide check 41. Accordingly, when the drive shoe 21 subsequently moves to the rear of the vehicle, the rotation check 46, the slide check 41, and the rotation check are performed in accordance with the switching to the disengaged state by the pressing action between the rotation cam 51 and the fixed cam 52. The drive shoe 21 moves to the rear of the vehicle together with the fixed cam 52 with the cam 51 left.

  At this time, the locking pin 36 runs idle in the allowable hole 43a so as to descend along the allowable hole 43a of the slide check 41, and the elevating guide pin 35 moves down the guide groove 22a and reaches its end. Accordingly, the movable panel 12 performs a tilt-down operation, and shifts to the fully closed state through the first tilt-up state.

Next, the operation of this embodiment will be described.
As described above, the movable panel 12 moves when the engagement protrusion 46a of the rotation check 46 is engaged with the engagement groove 60a of the guide block 60 in the fully closed state or the first tilt-up state, for example. Be regulated. At this time, the pressure contact surface 61a and the pressure contact surface 44a of the guide block 60 and the slide check 41 are in a pressure contact state. Therefore, even if the rotation check 46 rattles back and forth with respect to the guide block 60 due to product variation or assembly variation within the tolerance of the rotation check 46 or the guide block 60, the pressure contact surface 61a and the pressure contact surface 44a are not affected. The backlash of the slide check 41 in the front-rear direction is suppressed by the generated static friction force. Needless to say, the guide block 60 fixed directly to the guide rail 13 basically does not rattle in the front-rear direction.

  By the way, when the movable panel 12 is closed from the open state, the slide check 41 approaches the guide block 60 from the rear of the vehicle, so that the engagement protrusion 46a is engaged with the engagement groove 60a. The pressure contact surface 61a and the pressure contact surface 44a are in a pressure contact state. In the present embodiment, as shown in an enlarged view in FIG. 5, a substantially arc-shaped chamfered portion 62 as a guide portion is formed at a corner portion of the rear end of the block-side protruding portion 61 on the vehicle inner side. Therefore, as shown by the change from FIG. 5A to FIG. 5B, even if the front end portion of the guide wall portion 44 and the position of the block side protruding portion 61 in the vehicle width direction are slightly overlapped, When the front end surface of the guide wall portion 44 starts to come into contact with the block side protruding portion 61 from the chamfered portion 62, the pressure contact between the pressure contact surface 61a and the pressure contact surface 44a is guided by the chamfered portion 62. In FIG. 5B, the pressure contact state of the pressure contact surface 61a and the pressure contact surface 44a is indicated by hatching for convenience.

  On the other hand, when the movable panel 12 is opened in the second tilt-up state, the slide check 41 is moved to the rear of the vehicle with a driving force exceeding the static friction force generated between the pressed contact surface 61a and the pressed contact surface 44a in the pressed contact state. It will be. The dimension in the front-rear direction of the block-side protrusion 61 that correlates with the static friction force is set in consideration of the driving force required for the motor 15 and the like.

As described above in detail, according to the present embodiment, the following effects can be obtained.
(1) In the present embodiment, the back and forth of the slide check 41 is rattled by the static friction force generated between the pressure contact surface 61 a of the guide block 60 and the pressure contact surface 44 a of the slide check 41. The shakiness in the front-rear direction of the movable panel 12 connected via the can be suppressed. And generation | occurrence | production of the abnormal noise resulting from such rattling can be suppressed.

  (2) In this embodiment, the pressure contact surface 61a is formed on the block-side protruding portion 61, so that the size of the block-side protruding portion 61 in the front-rear direction is changed, so that the pressure-contacted surface 61a in the pressure contact state is changed. And the static friction force generated between the pressure contact surfaces 44a can be easily adjusted. Thereby, for example, the necessity of increasing the driving force required to start the movement of the slide check 41 relative to the guide block 60 with the opening operation of the movable panel 12 is reduced.

  Further, when the pressure contact surface 61a and the pressure contact surface 44a start to come into pressure contact during the closing operation from the open state of the movable panel 12, the driving force required for the motor 15 increases. Therefore, for example, when the driving force of the motor 15 has a function of determining the pinching by the movable panel 12 when the driving force exceeds a predetermined threshold value, the pinching may be erroneously determined due to the increase of the driving force. However, by adjusting the arrangement position of the block-side protruding portion 61 in the front-rear direction, for example, by pressing the pressure contact surface 61a and the pressure contact surface 44a within a range that does not require pinching determination, such erroneous determination of pinching is suppressed. be able to.

  (3) In the present embodiment, when the slide check 41 moves forward of the vehicle with respect to the guide block 60, that is, when the movable panel 12 is closed in the second tilt-up state, the chamfer 62 The pressure contact surface 61a and the pressure contact surface 44a can be more smoothly shifted to the pressure contact state.

  (4) In this embodiment, since the engagement protrusion 46a is engaged with the engagement groove 60a related to the movement restriction of the slide check 41 and the like by the rotation operation of the rotation check 46, these engagement grooves 60a. In addition, it is difficult to secure a surface for suppressing backlash in the front-rear direction between the engaging protrusions 46a. For this reason, it becomes more effective to suppress the back-and-forth movement of the movable panel 12 using the static friction force generated between the pressed surface 61a and the pressed surface 44a.

In addition, you may change the said embodiment as follows.
In the embodiment, the chamfered portion 62 is formed on the guide block 60 (block side protruding portion 61). Instead of this, or in addition to this, a substantially arc-shaped chamfered portion as a guide portion may be formed at a corner portion of the front end of the guide wall portion 44 on the vehicle outer side.

In the embodiment, the chamfered portion 62 of the guide block 60 (block side protruding portion 61) may be omitted.
In the embodiment, the block-side protruding portion 61 is provided to protrude from the front end portion of the guide block 60, and the pressure contact surface 61 a is formed on the block-side protruding portion 61. Instead of this, or in addition to this, a sliding member side protruding portion is provided in the front end portion of the guide wall portion 44 toward the guide block 60 in the width direction of the vehicle, and is pressed against the sliding member side protruding portion. A surface may be formed. Even in this case, the static friction force generated between the pressure contact surface and the pressure contact surface in the pressure contact state can be easily adjusted by changing the dimension in the front-rear direction of the sliding member side protrusion.

  -In the said embodiment, the to-be-contacted surface formed over the substantially full length of the front-back direction of the guide block 60 may be sufficient. That is, the pressure contact surface may be formed without unevenness of the guide block 60 in the width direction of the vehicle.

In the embodiment, the guide block 60 may be provided integrally with the guide rail 13 (flange 17) by, for example, outsert molding.
In the above-described embodiment, the guide block and the check constituting the check mechanism are engaged with the engagement protrusion in the engagement groove of the guide block by, for example, raising and lowering the engagement protrusion without rotating the check. Alternatively, the engagement protrusion may be removed from the engagement groove.

In the embodiment described above, the fixed cam 52 and the rotating cam 51 are disposed on the drive shoe 21 and the slide check 41, but the disposition relationship between them may be reversed.
In the above embodiment, the rotation check 46 and the engagement / disengagement switching mechanism 50 (the rotation cam 51 and the fixed cam 52) are arranged coaxially, but these axes may be different from each other as long as they extend in the front-rear direction. .

  In the above-described embodiment, the two steps of the first tilt-up state and the second tilt-up state in which the movable panel 12 is further tilted up than the first tilt-up state are adopted as the tilt-up state of the movable panel 12. On the other hand, the posture in the initial tilt-up state when the movable panel 12 shifts from the fully closed state may coincide with the posture in the tilt-up state when the movable panel 12 slides.

  -In the said embodiment, the connection aspect of the drive shoe 21 and the support bracket 31 (movable panel 12) is an example. For example, a guide groove opposite to the guide groove 22 a may be formed in the support bracket 31 (vertical wall portion 32), and an elevating guide pin that is movably fitted in the guide groove may be fixed to the drive shoe 21.
