DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, a mounting structure for a window regulator unit according to an embodiment will be described with reference to the drawings. In each drawing, FR and RR respectively indicate the front and rear of the vehicle door in the longitudinal direction, IS and OS respectively indicate the inward and outward directions in the interior and exterior directions, and UP and DN respectively indicate the upward and downward directions in the vertical direction of the vehicle door. The forward direction in the longitudinal direction of the vehicle door refers to the direction in which a rotation axis (hinge) that rotatably supports the vehicle door relative to the vehicle body is provided in the vehicle door. The rear direction in the longitudinal direction of the vehicle door refers to the direction opposite to the direction in which the hinge is provided in the vehicle door. In the following description, the forward and rear directions in the longitudinal direction of the vehicle door, the upward and downward directions in the vertical direction of the vehicle door, and the inner and outer directions in the interior and exterior directions are simply referred to as "front," "rear," "upper," "lower," "interior," and "outer directions," respectively. Elements having the same functions are designated by the same reference numerals, and redundant descriptions will be omitted.

[0010] The mounting structure for a window regulator unit according to the embodiment can be used to mount a window regulator unit in a vehicle door of a passenger car or a light truck (SUV, pickup truck, etc.).

[0011] The mounting structure for a window regulator unit according to this embodiment includes a door inner panel 10, a guide member 50, and a support member 60, as shown in FIGS.

[0012] The vehicle door 1 is a door that separates the interior and exterior of a vehicle (not shown) and is attached to a vehicle entrance / exit opening so as to be able to open and close. In this embodiment, the vehicle door 1 is supported on the front side of the vehicle at the vehicle entrance / exit opening via a hinge (not shown) so as to be rotatable (rear-openable) in the interior / exit direction. However, for example, the vehicle door 1 may also be supported on the rear side of the vehicle at the vehicle entrance / exit opening via a hinge so as to be rotatable (front-openable).

[0013] As shown in FIG. 2 , the vehicle door 1 includes a door inner panel 10 and a door outer panel 20. The door inner panel 10 is a plate-like member that forms a wall surface on the interior side of the vehicle door 1 and has a substantially rectangular shape when viewed from the interior and exterior of the vehicle. An inner opening 10a is formed on the upper side of the door inner panel 10. The door inner panel 10 may include a reinforcing panel 10b that extends in the front-rear direction on the exterior side of the vehicle compartment and reinforces the door inner panel 10. The door outer panel 20 is a plate-like member that forms a wall surface on the exterior side of the vehicle compartment of the vehicle door 1 and has substantially the same shape as the door inner panel 10 when viewed from the interior and exterior of the vehicle, and has a bow-like cross-sectional shape that bulges outward from the cabin when viewed from the front and exterior of the vehicle. An outer opening 20a is formed on the upper side of the door outer panel 20. The edges of the inner opening 10a and the outer opening 20a substantially overlap when viewed from the interior and exterior of the vehicle.

[0014] The exterior portion of the vehicle door is formed by overlapping the door inner panel 10 and the door outer panel 20 in the interior-exterior direction of the vehicle, and the window portion of the vehicle door 1 is formed by the inner opening 10a and the outer opening 20a. A space S is formed between the door inner panel 10 and the door outer panel 20. The window portion is opened and closed by the window panel 30 moving up and down between this space S and the window portion. For example, when the window panel 30 is raised to the uppermost position, the window portion is blocked by the window panel 30 (closed state), and when the window panel 30 is lowered, the window portion is not blocked by the window panel 30 (open state).

[0015] 1 and 2, the window panel 30 is supported by a window regulator unit 40 disposed in the space S so that it can be raised and lowered. As shown in FIG. 3, the window regulator unit 40 includes a guide member 50, a support member 60, a lifting member 41, a drive unit 42, and a wire 43, and is disposed outside the vehicle compartment of the door inner panel 10. The center portion of the door inner panel 10 is formed to bulge toward the interior of the vehicle compartment so that the drive unit 42 can be accommodated therein. This makes it possible to prevent an increase in the thickness of the vehicle door 1 in the interior / exterior direction in the area that does not overlap with the drive unit 42 when viewed from the interior / exterior direction.

[0016] The guide member 50 is an elongated member that extends in the vertical direction outside the vehicle compartment of the door inner panel and has a hat-shaped cross section that opens outward in a plan view. As shown in Fig. 2, the guide member 50 has a shape that bulges outward toward the vehicle compartment when viewed in the front-rear direction of the vehicle door. A support member 60 is provided between an upper end 50U and a lower end 50D of the guide member 50, and the support member 60 abuts against and is fixed to the door inner panel 10, thereby supporting the guide member 50 on the door inner panel 10.

[0017] 8, the surface (contact surface 60a) of the support member 60 that contacts the door inner panel 10 is formed so that its peripheral edge is bent and raised toward the outside of the vehicle compartment. In other words, the peripheral edge of the surface (contact surface 60a) of the support member 60 that contacts the door inner panel 10 is curved toward the outside of the vehicle compartment. Therefore, a curved surface R that bends from the contact surface 60a toward the outside of the vehicle compartment is formed at the peripheral edge of the contact surface 60a.

[0018] The upper end portion 50U of the guide member 50 refers to a region including the upper edge of the guide member 50 and the vicinity thereof. Specifically, it refers to a region extending downward from the upper edge of the guide member 50 at a predetermined ratio to the vertical dimension of the guide member 50. The predetermined ratio can be set appropriately depending on the longitudinal or transverse dimension of the guide member 50, its position relative to the door inner panel 10, its installation structure, etc. For example, in one embodiment, the predetermined ratio to the vertical dimension of the guide member 50 may be one-fifth. In this embodiment, the upper end portion 50U is a portion of the guide member 50 that is located above an upper support member 60U, which will be described later.

[0019] The lower end portion 50D of the guide member 50 refers to a region including the lower edge of the guide member 50 and the vicinity thereof. Specifically, it refers to a region extending upward from the lower edge of the guide member 50 at a predetermined ratio to the vertical dimension of the guide member 50. The predetermined ratio can be set appropriately depending on the longitudinal or transverse dimension of the guide member 50, its position relative to the door inner panel 10, its installation method, and the like. For example, in one embodiment, the predetermined ratio to the vertical dimension of the guide member 50 may be one-fifth. In this embodiment, the lower end portion 50D is a portion of the guide member 50 that is located below a lower support member 60D (described later).

[0020] The illustrated support members 60 include an upper support member 60U located at the uppermost position and a lower support member 60D located at the lowermost position. However, the number of support members 60 may be one or two or more. In other words, it is sufficient that at least one support member 60 that supports the guide member 50 is provided between the upper end 50U and the lower end 50D of the guide member 50.

[0021] The lifting member 41 is a block-shaped member that is supported on the outer side of the vehicle compartment of the guide member 50 so as to be able to lift and lower. As shown in Figs. 1 and 2, a lower end of the window panel 30 is supported on the outer side of the vehicle compartment of the lifting member 41 via a fixing device such as a bracket. In other words, the window panel 30 is supported on the guide member 50 so as to be able to lift and lower. Therefore, when the lifting member 41 moves up and down along the guide member 50, the window panel 30 moves up and down between the window portion of the vehicle door 1 and the space S, thereby opening and closing the window portion.

[0022] The drive unit 42 is fixed via a bracket or other fixing device to the interior side of the vehicle at approximately the center in the up-down direction of the guide member 50. Furthermore, the interior side of the drive unit 42 is fixed to the door inner panel 10 via a bracket or other fixing device. The drive unit 42 also includes a motor 42a and a winding portion 42b.

[0023] The winding section 42b includes a cylindrical winding drum (not shown) having a central axis of a winding shaft that extends from the interior to the exterior of the vehicle inside the drive unit 42. The shaft rotation of the motor 42a is transmitted to the winding drum via a worm gear (not shown) and a reducer (not shown) attached to the shaft. Therefore, by controlling the rotation direction of the motor 42a, the rotation of the winding drum around the winding shaft can be controlled.

[0024] The wire 43 is composed of an ascending wire 43a and a descending wire 43b. One end of the ascending wire 43a is fixed to the lifting member 41. The ascending wire 43a extends upward from the lifting member 41, extends downward and forward along a guide pulley 51 journaled at the upper end of the guide member 50, and is wound around the winding drum a predetermined number of times, after which the other end is fixed to the winding drum. One end of the descending wire 43b is fixed to the lifting member 41. The descending wire 43b extends downward from the lifting member 41, extends upward and forward along a guide pulley 51 journaled at the lower end of the guide member 50, and is wound around the winding drum a predetermined number of times, after which the other end is fixed to the winding drum.

[0025] Therefore, by controlling the rotation of the motor 42a, the forward rotation (clockwise rotation in FIG. 3) or reverse rotation (counterclockwise rotation in FIG. 3) of the winding drum can be controlled, which in turn controls the winding or unwinding of the raising wire 43a or the lowering wire 43b, thereby controlling the raising and lowering of the lifting member 41. For example, by transmitting the driving force of the motor 42a to the winding drum and rotating the winding drum forward, the raising wire 43a can be wound onto the winding drum and the lowering wire 43b can be unwound from the winding drum, thereby lifting the lifting member 41. Since the lifting member 41 supports the lower end of the window panel 30, the window panel 30 also rises, allowing the window portion of the vehicle door 1 to be closed. In this way, the window regulator unit 40 can control the raising and lowering of the window panel 30 and switch the window portion of the vehicle door 1 between an open state and a closed state.

[0026] Next, the configuration of the guide member 50 will be described in more detail.

[0027] 1 to 5, an upper elastic member 70 is interposed between an upper end portion 50U of the guide member 50 and a region (upper opposing portion 11) of the door inner panel 10 that faces the upper end portion 50U of the guide member 50 in the interior / exterior direction of the vehicle cabin of the door inner panel 10. In the illustrated example, the upper elastic member 70 is fixed to the upper end portion 50U of the guide member 50, but the upper elastic member 70 may also be fixed to the upper opposing portion 11 of the door inner panel 10.

[0028] As shown in FIG. 5 , the upper elastic member 70 is disposed with a gap between it and the upper opposing portion 11 of the reinforcing panel 10b (door inner panel 10) in the interior-exterior direction. The size of the gap is not particularly limited, but is, for example, 0.1 mm to 1 mm. When the upper elastic member 70 is provided on the upper opposing portion 11, the upper elastic member 70 may be disposed with a gap between it and the upper end portion 50U in the interior-exterior direction. In other words, the upper elastic member 70 may be disposed spaced apart from either the upper opposing portion 11 of the door inner panel 10 or the upper end portion 50U of the guide member 50 in the interior-exterior direction. However, the upper end portion 50U and the upper elastic member 70 may be in contact with each other and the upper elastic member 70 may be in contact with the upper opposing portion 11 in the interior-exterior direction. Furthermore, the upper elastic member 70 may be disposed in a state in which it is deformed and distorted due to compression (compressed state) between the upper end portion 50U and the upper opposing portion 11.

[0029] The upper elastic member 70 shown in FIG. 4 is entirely made of a rubber material. The upper elastic member 70 may include an upper rubber member 70a made of a rubber material and provided on the cabin-side upper end 50U of the guide member 50. In the illustrated example, the upper rubber member 70a is directly fixed to the guide member 50. More specifically, grooves provided below the upper rubber member 70a of the upper elastic member 70 clamp the upper edge of the guide member 50, thereby directly fixing the upper rubber member 70a to the guide member 50. Alternatively, the upper rubber member 70a may be directly fixed to the cabin-side upper end 50U of the guide member 50 using an adhesive or other method, for example. This reduces the number of components in the window regulator unit 40 according to this embodiment, and simplifies the installation structure for the window regulator unit 40 according to this embodiment.

[0030] 1 to 3, in the window regulator unit 40 according to the embodiment, a lower elastic member 80 may be interposed between the lower end portion 50D of the guide member 50 and a region (lower opposing portion 12) of the door inner panel 10 that faces the lower end portion 50D in the interior and exterior directions of the vehicle. In the illustrated example, the lower elastic member 80 is fixed to the lower end portion 50D of the guide member 50 on the interior side of the vehicle, but the lower elastic member 80 may also be fixed to the lower opposing portion 12 of the door inner panel 10 on the exterior side of the vehicle.

[0031] The illustrated lower elastic member 80 has its exterior side fixed to the lower end 50D of the guide member 50 and its interior side pressed against the lower opposing portion 12 of the door inner panel 10. Therefore, the lower elastic member 80 is pressed by the lower end 50D and the lower opposing portion 12 in the interior-exterior direction of the vehicle and is therefore placed in a compressed state. In other words, the lower elastic member 80 is placed in a state of contact with both the lower opposing portion 12 of the door inner panel 10 and the lower end 50D of the guide member 50 in the interior-exterior direction of the vehicle and is also placed in a compressed state. However, the placement method is not limited to this, and the lower elastic member 80 fixed to the lower end 50D of the guide member 50 may be spaced apart from the door inner panel 10. Furthermore, when the lower elastic member 80 is fixed to the exterior side of the lower opposing portion 12 of the door inner panel 10, the lower elastic member 80 may be spaced apart from the guide member 50.

[0032] As shown in Figures 6 and 7, the lower elastic member 80 includes a leaf spring member 80b extending from the lower end portion 50D of the guide member 50 toward the interior of the vehicle cabin, and a lower rubber member 80a provided on the interior side of the leaf spring member 80b.

[0033] The leaf spring member 80b is a bent plate-like member having a substantially Z-shaped cross section when viewed in the front-rear direction. The front-rear dimension of the leaf spring member 80b is substantially the same as the front-rear dimension of the lower end portion 50D of the guide member 50. The upper side of the leaf spring member 80b is fixed to the interior side of the lower end portion 50D of the guide member 50. The lower side of the leaf spring member 80b extends upright from the guide member 50 toward the interior of the vehicle, and the tip is bent downward. In this manner, the leaf spring member 80b, which is elastic in the interior and exterior directions, is fixed to the lower end portion 50D of the guide member 50.

[0034] The lower rubber member 80a is made of a rubber material and has a substantially rectangular cross-sectional shape when viewed from the inside and outside of the vehicle. The longitudinal dimension of the lower rubber member 80a is slightly larger than the longitudinal dimension of the leaf spring member 80b. The exterior side of the lower rubber member 80a is fixed to the leaf spring member 80b. The interior side of the lower rubber member 80a has a lower rubber member surface that faces the lower opposing portion 12 of the door inner panel 10, and a recess 80c is formed on this surface. The recess 80c is a groove extending in the vertical direction on the surface of the lower rubber member and has a substantially rectangular shape when viewed from the inside and outside of the vehicle. The recess 80c forms an uneven surface on the surface of the lower rubber member. In one embodiment, the interior dimension of the lower rubber member 80a is approximately 10 mm, and the interior dimension of the recess 80c is approximately 2 mm. However, these dimensions are not limited to these.

[0035] Furthermore, the lower elastic member 80 is disposed with its rear side pressed more strongly against the door inner panel 10 than its front side. Therefore, the distal portion 80d of the lower elastic member 80 is disposed in a state of being compressed more than the proximal portion 80e. More specifically, for example, the lower rubber member may be disposed with a gradient in the front-to-rear direction on the surface so that the distal portion 80d is located closer to the interior of the vehicle than the proximal portion 80e when viewed in the up-down direction. The distal portion 80d is a region of the lower elastic member 80 that is farther from the rotation axis (hinge) of the vehicle door 1, and the proximal portion 80e is a region of the lower elastic member 80 that is closer to the rotation axis (hinge) than the distal portion 80d.

[0036] The elastic modulus of the lower elastic member 80 may be set lower than the elastic modulus of the upper elastic member 70. For example, in one embodiment, a rubber member with a Shore hardness (Hs) of 60 may be used as the lower rubber member 80a, and a rubber member with an Hs of 70 may be used as the upper rubber member 70a.

[0037] Next, with reference to FIGS. 9 and 10, the operation of the mounting structure for the window regulator unit 40 according to the embodiment when the vehicle door 1 is closed will be described.

[0038] When an occupant gets into or gets out of a vehicle, an operation is performed to change the vehicle door 1 from an open state to a closed state. Because the front of the vehicle door 1 is attached to the vehicle via a hinge, in this operation, the vehicle door 1 first rotates around the hinge toward the vehicle entrance / exit opening and approaches the vehicle entrance / exit opening at a speed facing inward into the vehicle compartment. Then, when the peripheral portion of the vehicle door 1 abuts against the peripheral portion of the vehicle entrance / exit opening, an external force facing outward from the vehicle compartment is input to the vehicle door 1. As a result, acceleration toward the outside of the vehicle compartment occurs in the vehicle door 1, and the vehicle door 1 abruptly reduces its speed and comes to a standstill relative to the vehicle. In other words, the vehicle door 1 that abuts against the vehicle entrance / exit opening at a speed facing inward into the vehicle compartment comes to a standstill relative to the vehicle due to the acceleration generated when the vehicle door 1 is closed. The acceleration when the vehicle door 1 is closed refers to the acceleration directed toward the outside of the vehicle compartment that occurs as a result of an external force being input to the vehicle door 1 toward the outside of the vehicle compartment when the peripheral edge of the vehicle door 1 abuts against the peripheral edge of the vehicle entrance / exit opening when the vehicle door 1 is closed.

[0039] When acceleration occurs when the vehicle door 1 is closed, an inertial force directed toward the interior of the vehicle cabin is generated in the window regulator unit 40. As a result of the inertial force, a load is input from the support member 60 to the door inner panel 10 in the direction of arrow B, as shown in FIG. 9 . This causes the door inner panel 10 to elastically deform, and the upper end 50U of the guide member 50 and the upper opposing portion 11 of the door inner panel 10 move relatively closer to each other. Also, the lower end 50D of the guide member 50 and the lower opposing portion 12 of the door inner panel 10 move relatively closer to each other. Note that the door inner panel 10 may elastically deform in various ways, such as rotating the upper opposing portion 11 and the lower opposing portion 12 of the door inner panel 10 in the direction of arrow C around the support member 60 as a fulcrum, or pushing the support member 60 against the door inner panel 10, causing the guide member 50 and the door inner panel 10 to move closer together as a whole.

[0040] (1) The mounting structure according to the embodiment is a mounting structure for a window regulator unit 40, and includes a door inner panel 10 that constitutes the interior side of a vehicle door 1, and a guide member 50 that extends in the vertical direction outside the vehicle compartment of the door inner panel 10 and supports the window panel 30 so that it can be raised and lowered. At least one support member 60 that is fixed to the door inner panel 10 and supports the guide member 50 is provided between an upper end 50U and a lower end 50D of the guide member 50, and an upper elastic member 70 is interposed between the upper end 50U of the guide member 50 and an upper opposing portion 11 of the door inner panel 10 that faces the upper end 50U in the interior and exterior directions of the vehicle, and is configured so that the upper end 50U and the upper opposing portion 11 approach each other and compress the upper elastic member 70 due to elastic deformation caused by acceleration at least when the vehicle door 1 is closed.

[0041] Therefore, as the upper end portion 50U of the guide member 50 and the upper opposing portion 11 of the door inner panel 10 relatively approach each other, the upper elastic member 70 and the upper opposing portion 11 come into contact with each other, and a compressive force is input to the upper elastic member 70 between the upper end portion 50U and the upper opposing portion 11. Then, a reaction force (restoring force) of the upper elastic member 70 in a compressed state is input to the upper end portion 50U and the upper opposing portion 11. At this time, a part of the load caused by the inertial force of the window regulator unit 40 directed toward the interior of the vehicle cabin due to acceleration generated when the vehicle door 1 is closed is input to the door inner panel 10 through the upper elastic member 70. Therefore, the load is distributed to the support member 60 and the upper elastic member 70 and input to the door inner panel 10. Therefore, the load input from the support member 60 of the window regulator unit 40 toward the door inner panel 10 when the vehicle door 1 is closed can be reduced. Furthermore, when the vehicle door 1 is closed, the window portion of the vehicle door 1 is often in a closed state. In such a case, since the window panel 30 is supported on the upper side of the guide member 50, the center of gravity of the window regulator unit 40 is located at a higher position in the vertical direction. Therefore, when acceleration occurs when the vehicle door 1 is closed, a larger inertial force is generated on the upper side of the guide member 50. Therefore, by providing the upper elastic member 70 at the upper end portion 50U, it is possible to reduce the number of components of the window regulator unit 40 according to the embodiment, while effectively distributing the load caused by the inertial force of the window regulator unit 40 to the support member 60 and the upper elastic member 70, and reducing the load input from the support member 60 toward the door inner panel 10.

[0042] (2) In the mounting structure according to the embodiment, the upper elastic member 70 includes an upper rubber member 70a provided on the upper end portion 50U of the guide member 50 on the side facing the interior of the vehicle.

[0043] As a result, the upper rubber member 70a absorbs the load distributed to the upper elastic member 70, which is caused by the inertial force of the window regulator unit when the vehicle door 1 is closed, and the generation of low-pitched noise due to contact between the upper opposing portion 11 and the upper elastic member 70 can be suppressed.

[0044] (3) In the mounting structure according to the embodiment, the upper rubber member 70a is fixed directly to the guide member 50.

[0045] Therefore, the number of parts required to configure the mounting structure for the window regulator unit 40 according to the embodiment can be reduced, and the mounting structure can be configured simply.

[0046] (4) In the mounting structure according to the embodiment, a lower elastic member 80 is interposed between the lower end portion 50D of the guide member 50 and the lower opposing portion 12 of the door inner panel 10 that faces the lower end portion 50D in the interior and exterior directions of the vehicle, and is configured so that the lower end portion 50D and the lower opposing portion 12 approach each other and compress the lower elastic member 80 due to elastic deformation caused by acceleration at least when the vehicle door 1 is closed.

[0047] Therefore, the lower end portion 50D of the guide member 50 and the lower opposing portion 12 of the door inner panel 10 come relatively close to each other, and a compressive force is input to the lower elastic member 80 between the lower end portion 50D and the lower opposing portion 12. Then, a reaction force (restoring force) of the lower elastic member 80 in a compressed state is input to the lower end portion 50D and the lower opposing portion 12. At this time, a part of the load caused by the inertial force of the window regulator unit 40 directed toward the interior of the vehicle compartment due to acceleration generated when the vehicle door 1 is closed is input to the door inner panel 10 through the lower elastic member 80. Therefore, the load is distributed among the support member 60, the upper elastic member 70, and the lower elastic member 80 and input to the door inner panel 10. Therefore, the load input from the support member 60 of the window regulator unit 40 toward the door inner panel 10 when the vehicle door 1 is closed can be more reliably reduced. Furthermore, when the window is open when the vehicle door 1 is closed, the window panel 30 is supported by the lower side of the guide member 50, so the center of gravity of the window regulator unit 40 is located at a lower position in the vertical direction. Therefore, when acceleration occurs when the vehicle door 1 is closed, a larger inertial force is generated on the lower side of the guide member 50. Therefore, when the vehicle door is closed, a larger load may be input to the lower support member 60D. Furthermore, due to design considerations, it may be difficult to increase the rigidity of the portion of the door inner panel 10 to which the lower support member 60D is fixed and its surrounding area. Even in such a case, the load is distributed to the lower elastic member 80, so that the load input from the lower support member 60D toward the door inner panel 10 can be more reliably reduced.

[0048] (5) In the mounting structure according to the embodiment, the elastic modulus of the lower elastic member 80 is lower than the elastic modulus of the upper elastic member 70 .

[0049] Therefore, the reaction force that the lower elastic member 80 in a compressed state applies to the lower end portion 50D and the door inner panel 10 is smaller than the reaction force that the upper elastic member 70 in a compressed state applies to the upper end portion 50U and the door inner panel 10. This prevents the sum of the reaction forces of the upper elastic member 70 and the lower elastic member 80 from becoming excessively large, and more reliably distributes the load caused by the inertial force of the window regulator unit 40 that occurs when the vehicle door 1 is closed to the support member 60, the upper elastic member 70, and the lower elastic member 80. In other words, the elastic modulus of the upper elastic member 70 is higher than the elastic modulus of the lower elastic member 80. Therefore, even when the window panel 30 is raised and the center of gravity of the window regulator unit 40 is located at a high position in the vertical direction, excessive compression of the upper elastic member 70 can prevent the load caused by the inertial force of the window regulator unit 40 from being excessively applied to the upper support member 60U when the vehicle door 1 is closed.

[0050] (6) In the mounting structure according to the embodiment, the upper elastic member 70 is positioned in a state spaced apart from either the upper opposing portion 11 of the door inner panel 10 or the upper end portion 50U of the guide member 50 in the interior / exterior direction of the vehicle, and the lower elastic member 80 is positioned in a state of contact with and compressed by both the lower opposing portion 12 of the door inner panel 10 and the lower end portion 50D of the guide member 50 in the interior / exterior direction of the vehicle.

[0051] The operation of such a configuration will be explained with reference to Figure 10 using an example mounting structure in which, for example, the upper elastic member 70 fixed to the interior side of the upper end portion 50U is positioned with a gap between it and the upper opposing portion 11 in the interior / exterior direction of the vehicle, and the lower elastic member 80 fixed to the interior side of the lower end portion 50D is pressed against the lower opposing portion 12 and positioned in a compressed state.

[0052] The horizontal axis X in FIG. 10 represents the relative movement (push amount) of the window regulator unit 40 with respect to the door inner panel 10 when the vehicle door 1 is closed. The vertical axis Y represents the sum (total reaction force) of the magnitude of the reaction force input by the lower elastic member 80 to the lower end portion 50D and the lower opposing portion 12 and the magnitude of the reaction force input by the upper elastic member 70 to the upper end portion 50U and the upper opposing portion 11 at a certain push amount. The solid line L represents the change in the total reaction force with respect to the change in push amount. The origin O represents a state in which there is no relative movement of the window regulator unit 40 with respect to the door inner panel 10. XC represents the push amount when the upper end portion 50U and the upper opposing portion 11 come relatively closer to each other as the vehicle door 1 is closed, causing the upper elastic member 70 and the upper opposing portion 11 to come into contact.

[0053] First, at the origin O, the upper elastic member 70 is not compressed and therefore does not exert a reaction force. On the other hand, the lower elastic member 80 is disposed in a compressed state and therefore exerts a predetermined reaction force of magnitude Y0. When the vehicle door 1 is closed and the pushing amount increases, the lower elastic member 80 is compressed more strongly, and the magnitude of the reaction force of the lower elastic member 80 increases to YC, as indicated by the change in the solid line L from the origin O to XC. In this state, the load caused by the inertial force of the window regulator unit 40 when the vehicle door 1 is closed is distributed to the support member 60 and the lower elastic member 80. Furthermore, after the upper elastic member 70 and the upper opposing portion 11 come into contact with each other at the pushing amount XC, when the pushing amount becomes greater than XC, the upper elastic member 70 is compressed between the upper end portion 50U and the upper opposing portion 11. At this time, the upper elastic member 70 and the lower elastic member 80 exert reaction forces, and therefore the total reaction force increases more significantly than when the pushing amount is equal to or less than XC. In this state, the load is distributed to the support member 60, the upper elastic member 70, and the lower elastic member 80. According to the above-described action, regardless of the position of the window panel 30 in the vertical direction, the load caused by the inertial force of the window regulator unit 40 generated when the vehicle door 1 is closed is first distributed to the support member 60 and the lower elastic member 80. Next, as the upper end portion 50U and the upper opposing portion 11 come relatively close to each other, the upper elastic member 70 and the upper opposing portion 11 come into contact with each other, and the load is further distributed to the upper elastic member 70 as well. Therefore, regardless of the position of the window panel 30 in the vertical direction, the load can be more reliably distributed to the support member 60, the upper elastic member 70, and the lower elastic member 80. Furthermore, for example, when the window portion of the vehicle door 1 is in a closed state and the center of gravity of the window regulator unit 40 is located at a high position in the vertical direction, after the upper elastic member 70 and the upper opposing portion 11 come into contact, a moment may be generated in which the window panel 30 rotates toward the inside of the vehicle cabin, with the upper elastic member 70 as a fulcrum, and the lower end portion 50D rotates toward the outside of the vehicle cabin. Even in such a case, the load can be more reliably distributed to the lower elastic member 80 before the moment is generated.

[0054] (7) In the mounting structure according to the embodiment, the lower elastic member 80 includes a leaf spring member 80b extending from the lower end portion 50D of the guide member 50 toward the interior of the vehicle cabin, and a lower rubber member 80a provided on the interior side of the leaf spring member 80b.

[0055] Therefore, when the vehicle door 1 is closed, the load caused by the inertial force of the window regulator unit 40 and distributed to the lower elastic member 80 can be absorbed by the leaf spring member 80b.

[0056] (8) In the mounting structure according to the embodiment, the lower rubber member 80a has a recess 80c on the surface of the lower rubber member 80a that faces the door inner panel 10.

[0057] This prevents the lower rubber member 80a from inputting excessive reaction force into the door inner panel 10. Furthermore, it is possible to prevent the lower rubber member 80a from sticking to the door inner panel 10, and also to prevent the generation of noise (attachment noise) that occurs when the lower rubber member 80a adheres to or peels off from the door inner panel.

[0058] (9) In the mounting structure according to the embodiment, the distal portion 80d of the lower elastic member 80, which is farther from the rotation axis of the vehicle door 1, is positioned in a more compressed state than the proximal portion 80e, which is closer to the rotation axis than the distal portion 80d.

[0059] For this reason, when the vehicle door 1 is closed, the load that the distal portion 80d of the lower elastic member 80 applies to the door inner panel 10 is greater than the load that the proximal portion 80e applies to the door inner panel 10. This makes it possible to prevent the window regulator unit 40 from rotating rearward about an axis in the vertical direction when the vehicle door is closed.

[0060] (10) In the mounting structure according to the embodiment, the peripheral edge of the surface of at least one support member 60 that abuts against the door inner panel 10 is bent outward toward the outside of the vehicle compartment.

[0061] Therefore, the load caused by the inertial force of the window regulator unit 40 when the vehicle door 1 is closed is distributed to the contact surface 60a or the curved surface R formed on the peripheral edge thereof, and is input to the door inner panel 10. Therefore, compared to when an edge is formed on the peripheral edge of the contact surface 60a, it is possible to prevent the load from being input in a concentrated manner.

[0062] Furthermore, in the above embodiment, passenger cars and light trucks have been used as examples, but it goes without saying that the mounting structure of the window regulator unit 40 according to the embodiment can also be used for window regulator units for vehicle doors of commercial vehicles such as large trucks.
