  The door opening degree adjusting device is attached to the mounting wall in a state of being in contact with the mounting wall, and the stopper portion in a state where the check link is inserted and released from the adjusting member is contacted. Therefore, it is preferable to provide a door check that restricts the opening operation associated with the rotation of the door in one direction at the fully open position.

  According to this configuration, the opening operation accompanying the rotation of the door in one direction is restricted at the fully opened position by the stopper portion being in contact with the door check being released from the adjustment member. . At this time, a load input from the stopper portion to the door check is input to the wall portion via the mounting wall. In this case, the wall portion receives a load from the entire surface of the mounting wall in contact with the wall portion. For example, the holding strength of the wall portion is further increased as compared with a case where the load is concentrated from the door check. can do.

  With respect to the door opening degree adjusting device, the adjustment member may be arranged in a plurality of stages so that the check links can be sandwiched in a parallel direction different from the moving direction of the check links and the extending direction of the guide holes. A pair of adjustment walls provided with a stepped portion and a plurality of guide protrusions, and the guide member includes a pair of support walls formed with the guide holes so as to sandwich the adjustment member in the juxtaposed direction. The check link preferably includes a pair of the stopper portions so as to be able to abut against any one of the plurality of step portions of the two adjustment walls.

  According to this configuration, in the opening operation accompanying the rotation of the door in one direction, both the stopper portions of the check link are in contact with any one of the plurality of stepped portions of the adjustment walls. It is regulated by that. The adjusting member with which both the stopper portions abut is adjusted by opening the plurality of guide protrusions into each of the guide holes while being sandwiched between the both support walls. Beyond that, the door can be more firmly controlled from opening. In this case, the check link can further stabilize the posture of the check link by bringing the stopper portions into contact with the adjustment walls (step portions) that sandwich the check link in the juxtaposed direction. it can. Further, the guide member has the plurality of guide protrusions inserted into the guide holes of the two support walls that sandwich the adjustment member in the juxtaposed direction, so that the adjustment member is removed from the stopper portions. It is possible to more firmly support the load input to the two-sided state.

  Hereinafter, an embodiment of a door opening adjustment device will be described. Hereinafter, the upper direction and the lower direction in the height direction of the vehicle are referred to as “upper” 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”. In particular, the width direction of the vehicle with respect to the door (the vehicle inner side, the vehicle outer side) refers to that considered to be closed.

  As shown in FIG. 1, an opening 2 for getting on and off is formed in a side portion of a body 1 of the vehicle, and an edge 2 a in front of the opening 2 is arranged in parallel in the height direction of the vehicle. A door 4 is rotatably connected by a pair of door hinges 3. The door 4 is opened and closed by rotating in one direction and the other direction around the door hinge 3.

  In addition, a base end portion of a substantially long check link 11 made of, for example, a molding material obtained by integrating resin with a metal rod is connected to the edge portion 2a so as to be rotatable in accordance with the opening / closing direction of the door 4. The door 4 is fastened with a door check 16 through which a tip portion of the check link 11 entering the door 4 is movably inserted in the longitudinal direction. The check link 11 and the door check 16 constitute the door check mechanism 10.

  The check link 11 moves relative to the door check 16 (door 4) in the longitudinal direction while swinging about the base end portion in accordance with the opening / closing operation of the door 4. That is, as shown in FIGS. 2 (a) and 2 (b), the edge 2a is formed with a substantially flat mounting surface 5 that is recessed toward the inside of the vehicle, and the mounting surface 5 is made of, for example, a metal plate. A bracket 12 is fastened. On the other hand, the door 4 has a door outer panel 6 that extends so as to face the outside of the vehicle, and a box-shaped door inner panel 7 that is disposed on the inside of the vehicle. The edge of the door outer panel 6 and the opening of the door inner panel 7 are provided. A substantially sealed internal space is formed by joining the ends. Note that the door 4 is opened and closed by rotating about the shaft 3 a of each door hinge 3.

  The base end portion of the check link 11 is connected to the bracket 12 so as to be rotatable around an axis extending in the vehicle height direction, and the front end portion of the check link 11 is opposed to the rear of the mounting surface 5. It enters the door 4 through the wall portion 8 of the door inner panel 7. On the other hand, the door check 16 is fastened to the wall portion 8 in the door 4, and the tip end portion of the check link 11 entering the door 4 is inserted. As described above, the check link 11 moves relative to the door check 16 in the longitudinal direction while swinging about the base end portion in accordance with the opening / closing operation of the door 4. Then, as shown by a change from FIG. 2A to FIG. 2B, for example, when the door 4 is opened, the check link 11 is retracted from the door 4 through the door check 16 or the like. Conversely, when the door 4 is closed, the check link 11 enters the door 4 through the door check 16 or the like. That is, the relative position of the check link 11 to the door check 16 uniquely corresponds to the opening / closing position (opening) of the door 4. Specifically, the opening degree decreases as the length L of the check link 11 protruding from the door check 16 into the door 4 increases, and conversely, the opening degree increases as the length L decreases.

  As shown in FIG. 3, the check link 11 has a plurality of upper and lower pairs of valleys 13 and 14 formed at intervals in the longitudinal direction, and the door check 16 has one of the pair of valleys 13 and 14. A pair of rollers (not shown in the figure) are incorporated that slightly restrict the movement of the check link 11 in the longitudinal direction by sandwiching 14. Therefore, when the movement of the check link 11 in the longitudinal direction is slightly restricted by the door check 16, the door 4 is slightly held at the corresponding opening / closing position (opening).

  Further, as shown in FIG. 4, a pair of protruding piece-like stopper portions 15 that extend to both sides in the width direction of the vehicle are formed at the tip of the check link 11. These stopper portions 15 contact the door check 16 when the check link 11 tries to retract from the door 4 through the door check 16 or the like with the opening operation of the door 4, so The opening operation is restricted (see FIG. 2B). The open / close position (opening degree) of the door 4 at this time corresponds to the fully open position.

  A guide member 20 made of, for example, a metal plate is attached to the wall portion 8 of the door 4. The guide member 20 includes a substantially band-shaped mounting wall 21 extending in the height direction of the vehicle, and a pair of support walls extending rearward from both ends (the vehicle outer end and the vehicle inner end) of the mounting wall 21 in the vehicle width direction. 22 and has a substantially U-shape opening rearward. The guide member 20 is fastened (so-called joint fastening) to the wall portion 8 together with the door check 16 in a state where the mounting wall 21 is sandwiched between the wall portion 8 and the door check 16. The mounting wall 21 has an area sufficiently larger than the contact surface so as to surround the door check 16.

  Each support wall 22 is formed with a substantially rectangular guide hole 23 extending in the height direction of the vehicle. In addition, the guide member 20 has a top plate portion 24 that connects the upper edges of the tip portions of the support walls 22. A substantially circular insertion hole 25 that opens in the height direction of the vehicle is formed at the center of the top plate portion 24.

  As shown in FIG. 5, an adjustment member 30 made of, for example, a metal plate is supported on the guide member 20 while being sandwiched between the support walls 22. The adjustment member 30 has a pair of adjustment walls 31 that spread along the inner wall surfaces of the support walls 22. The distance in the vehicle width direction between the two adjustment walls 31 is basically set to be larger than the distance between the tips of the stopper portions 15 of the check link 11. Each adjustment wall 31 is formed in a substantially L shape in which the rearward extension length of the upper end portion 32 is longer than the rearward extension length of the lower end portion 33. Both adjustment walls 31 have a substantially L-shaped extending piece 34 that extends further rearward from the lower end of the upper end portion 32 and bends in the vehicle width direction from the rear end. The rear end surface of each extending piece 34 forms a first stepped portion 34a. Moreover, both the adjustment walls 31 have the substantially L-shaped extension piece 35 which bends in the width direction of the vehicle which extends further back from the vehicle height direction intermediate part of the lower end part 33, and approaches mutually from a rear end. A rear end surface of each extending piece 35 forms a second stepped portion 35a. That is, the distance in the vehicle width direction between the two adjustment walls 31 is reduced at the positions of the step portions 34a and 35a. The distance in the direction between both stepped portions 34 a and the distance in the direction between both stepped portions 35 a are equal to each other, and are set smaller than the distance between the tips of both stopper portions 15 of the check link 11. It goes without saying that the second stepped portion 35a is positioned forward and below the first stepped portion 34a.

  Each adjustment wall 31 is formed with a pair of substantially circular mounting holes 36 and 37 spaced in the height direction of the vehicle. The mounting holes 36 and 37 are arranged in front of the extending pieces 34 and 35 (steps 34 a and 35 a), respectively, and their inner diameters are set to be equal to the opening width of the guide hole 23 in the short direction. Yes. Moreover, the adjustment member 30 has the top-plate part 38 which connects the upper edges of both the adjustment walls 31 (upper end part 32). A substantially circular insertion hole 39 that opens in the height direction of the vehicle is formed at the center of the top plate portion 38.

  The adjustment member 30 is supported by the guide member 20 movably in the vehicle height direction by a pair of guide pins 41 and 42 as a pair of guide protrusions arranged in parallel in the vehicle height direction on each adjustment wall 31. ing. That is, the guide pins 41 and 42 have substantially disc-shaped head portions 41 a and 42 a having a diameter larger than the opening width in the short direction of the guide hole 23 and are equivalent to the opening width in the short direction of the guide hole 23. And substantially cylindrical insertion portions 41b and 42b protruding from the center of the heads 41a and 42a. The adjustment member 30 is supported by the guide member 20 by inserting and fastening the insertion portions 41b and 42b of the guide pins 41 and 42 inserted through the guide holes 23 from the outside of the support walls 22 into the mounting holes 36 and 37, respectively. Is done. At this time, the adjustment member 30 moves in the height direction of the vehicle with respect to the guide member 20 in a range from a position where the insertion portion 41 b contacts the upper end of the guide hole 23 to a position where the insertion portion 42 b contacts the lower end of the guide hole 23. Is possible.

  The insertion hole 39 of the adjustment member 30 is set so as to be substantially concentric with the insertion hole 25 of the guide member 20 and face the vehicle in the height direction. And between the top plate parts 24 and 38, the compression spring 43 which consists of coil springs, for example is interposed. Both ends of the compression spring 43 are in pressure contact with the peripheral portions of the insertion holes 25 and 39, respectively, and always urge the adjustment member 30 downward against the guide member 20.

  The lower end 45 of the cable 44 that basically extends in the height direction of the vehicle is sequentially inserted into the insertion holes 25 and 39 together with the compression spring 43. The terminal 45 is secured to the top plate portion 38 below the insertion hole 39. The terminal on the upper side of the cable 44 is connected to an adjustment dial 46 exposed in the passenger compartment (for example, on the door trim), and the vehicle between the top plate portion 24 and the terminal 45 is operated by turning the adjustment dial 46. The distance in the height direction is configured to be extendable. In other words, the adjustment member 30 urged downward by the compression spring 43 reduces the distance between the top plate portion 24 and the terminal 45 with respect to the guide member 20 as the adjustment dial 46 rotates in one direction. As the distance between the top plate portion 24 and the terminal 45 extends as the adjustment dial 46 rotates in the reverse direction, the adjustment dial 46 descends with respect to the guide member 20. At this time, the movement of the adjusting member 30 is guided by sliding the guide pins 41 and 42 in the respective guide holes 23. The adjustment dial 46 only needs to be equipped with a known mechanism that winds and unwinds the cable 44 in accordance with, for example, the turning operation.

Next, the operation of this embodiment will be described.
First, as shown in FIG. 6A, the position of the adjustment member 30 is adjusted by rotating the adjustment dial 46, and the extension piece 34 (first step Assume that a step 34a) is arranged. In this state, the opening operation of the door 4 is restricted by the stopper portions 15 of the check link 11 retracting from the door 4 coming into contact with the first stepped portion 34a. At this time, the length L of the check link 11 protruding from the door check 16 into the door 4 is L1, and the opening operation of the door 4 is restricted by the first opening. The guide pin 41 is arranged on an extension line E1 that connects the stopper portion 15 and the first stepped portion 34a in the moving direction of the check link 11. Therefore, the load input from the stopper portion 15 to the first stepped portion 34a is supported between the guide pin 41 and the guide hole 23 in the acting direction.

  Further, as shown in FIG. 6B, the position of the adjustment member 30 is adjusted by the turning operation of the adjustment dial 46, and the extension piece 35 (second step of the second stage) is moved on the movement track forward of the check link 11. It is assumed that the stepped portion 35a) is arranged. In this state, the opening operation of the door 4 is restricted by the check link 11 retracted from the door 4 or each stopper portion 15 coming into contact with the second stepped portion 35a. At this time, the length L of the check link 11 protruding from the door check 16 into the door 4 is L2 (<L1), and the opening operation of the door 4 is performed at a second opening larger than the first opening. Be regulated. The guide pin 42 is disposed on an extension line E2 that connects the stopper portion 15 and the second stepped portion 35a in the moving direction of the check link 11. Accordingly, the load input from the stopper portion 15 to the second stepped portion 35a is supported between the guide pin 42 and the guide hole 23 in the acting direction.

  Further, as shown in FIG. 6C, the position of the adjustment member 30 is adjusted by rotating the adjustment dial 46, and the adjustment member 30 (strictly, the extended piece 35) is disposed above the door check 16. Suppose that In this state, the opening operation of the door 4 is restricted when both stopper portions 15 of the check link 11 retracted from the door 4 come into contact with the door check 16. At this time, the length L of the check link 11 protruding from the door check 16 into the door 4 becomes zero, and the opening operation of the door 4 is restricted at the fully open position.
