  The present invention has been made in view of the above circumstances, and it is a technical problem to be solved to provide a storage body that can easily open and close the lid with a simple configuration that does not use a motor. .

  The storage body of the present invention that solves the above problems includes a main body having an opening and a guide, a lid that is supported by the main body so as to be able to open and close the opening, and the lid as the lid opens and closes. A rail that moves with the body, a rack provided on the rail, a pinion that meshes with the rack, a rail that is reciprocally held along the rail, and pivotally supports the pinion, A pin portion that is guided by engaging with the guide portion, and reciprocates along the rail by meshing of the rack and the pinion with the opening and closing movement of the lid, and the guide portion and the A slider that moves along the guide portion by engagement with the pin portion, one end is fixed to the main body side or the lid body side, and the other end is fixed to the slider, and as the lid body opens and closes, Expansion and contraction With accumulating a biasing force in Rukoto, it is characterized in that a biasing member for biasing at least one of the opening operation and closing operation of the lid member by 該付 force.

  In this storage body, the rail moves together with the lid body as the lid body opens and closes. Then, the pin portion of the slider held so as to be reciprocally movable with respect to the rail is guided by the guide portion of the main body, so that the slider moves along the guide portion, and the pinion and rail pivotally supported by the slide The slider reciprocates along the rail by meshing with the rack provided on the rail. That is, in this storage body, as the lid body opens or closes, the slider moves along the guide portion and moves forward along the rail (movement from one end of the rail to the other end). Or it moves backward (movement from the other end side of a rail to one end side). When the slider moves in this way, the urging member having one end fixed to the main body or the lid and the other end fixed to the slider expands and contracts, and the urging force is accumulated in the urging member.

  Here, the magnitude of the urging force accumulated in the urging member (the amount of expansion / contraction of the urging member), the direction of the urging force, the timing for accumulating the urging force, and the timing for releasing the accumulated urging force are Varies with shape. For this reason, if the shape of the guide part is appropriately set, the urging force accumulated in the urging member moves the slider along the guide part, thereby opening the lid together with the rail holding the slider. It can be closed.

  As described above, in the storage body according to the present invention, the urging force is accumulated in the urging member by opening and closing the lid, and the opening and closing operations of the lid are urged by the accumulated urging force. . In this way, the opening and closing operations of the lid can be performed using the biasing force accumulated in advance with the opening and closing movement of the lid, so that it is not necessary to separately provide an expensive drive source such as a motor. For this reason, it is possible to easily open and close the lid with a simple configuration without using a motor. Therefore, it is possible to prevent an increase in cost due to the use of an expensive drive source such as a motor.

  Further, by appropriately setting the shape of the guide portion, the strength and timing for energizing the opening and closing movement of the lid can be set as desired, and the degree of freedom in design is increased.

  In a preferred aspect, the storage body of the present invention is held by the slider, and the first damper that buffers the opening or closing operation of the lid, and the slider is interposed between the pinion and the first damper. And a clutch that turns on / off torque transmission between the pinion and the first damper.

  In this storage body, the torque transmission is turned on between the pinion and the first damper via the clutch, so that the function of the first damper works, and the opening or closing operation of the lid is buffered and shocks, etc. It can be lost. Then, when it is not desired to activate the first damper in some of the opening and closing operations of the lid, the torque transmission between the pinion and the first damper may be turned off by the clutch. For this reason, the opening operation and the closing operation of the lid body are smooth.

  In a preferred aspect of the storage body of the present invention, the clutch is a one-way clutch gear pivotally supported by the slider.

  In this storage body, torque transmission between the pinion and the first damper is turned on / off by the one-way clutch gear. Since this one-way clutch gear is pivotally supported by the slider and does not move, it operates stably and quietly.

  In a preferred aspect of the storage body of the present invention, the clutch reciprocates in the elongated hole formed in the slider by meshing with the pinion, so that either the opening operation or the closing operation of the lid is performed. The movable clutch gear is engaged with the first damper and separated from the other.

  In this storage body, the torque transmission between the pinion and the first damper is turned on / off when the movable clutch gear reciprocates in the elongated hole by meshing with the pinion.

  In a preferred aspect, the storage body of the present invention includes a second damper that has one end coupled to the rail and the other end coupled to the main body side, and cushions the opening or closing operation of the lid. .

  In this storage body, the opening operation or closing operation of the lid body is buffered by the second damper, so that an impact or the like during the opening operation or the closing operation can be eliminated. For this reason, the opening operation or closing operation of the lid is smooth.

  Here, the storage body of the present invention is held by the slider, and the slider is interposed between the first damper that buffers one of the opening operation and the closing operation of the lid, and the pinion and the first damper. And a clutch for turning on / off torque transmission between the pinion and the first damper, one end of which is coupled to the rail and the other end is coupled to the main body, and the lid body is opened and closed. It is more preferable to include a second damper that cushions the other of the two.

  In this storage body, torque transmission is turned on between the pinion and the first damper via the clutch, so that the function of the first damper works, and one of the opening and closing operations of the lid is buffered, The impact at the time of opening operation or closing operation can be eliminated. Then, when it is not desired to activate the first damper in some of the opening and closing operations of the lid, the torque transmission between the pinion and the first damper may be turned off by the clutch. Further, the other of the opening operation and the closing operation of the lid body is buffered by the second damper, so that an impact or the like during the opening operation or the closing operation can be eliminated. For this reason, the opening operation and the closing operation of the lid body are smoother.

  Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.

(Embodiment 1)
In the present embodiment, the storage body of the present invention is applied to a grab box provided on an instrument panel of a vehicle such as an automobile.

  As schematically shown in FIGS. 1 to 5, the storage body of the present embodiment includes a main body 1, a lid body 2, a rail 3, a rack 4, a pinion 5, a slider 6, and a biasing member. 7, a one-way clutch gear 8, a first damper 9, and a second damper 10.

  As shown in FIGS. 1 and 4, the main body 1 includes a synthetic resin box-shaped main body 11 having an opening 11 a and a substrate 12 made of a metal plate. The material of the substrate 12 is not particularly limited as long as it has a desired strength, and a synthetic resin or the like may be adopted. The substrate 12 is fixed to one side surface of the box-shaped main body 11 by bolts 13 by retrofitting. A groove-shaped guide portion 14 having a predetermined shape (substantially triangular shape in the present embodiment) is formed on the substrate 12.

  As shown in an enlarged view in FIG. 5, the guide portion 14 includes a closed end 15 at an uppermost position farthest from the opening 11 a of the box-shaped main body 11 in a state where the substrate 12 is fixed to the box-shaped main body 11. And an open end portion 16 at the lowest position closest to the opening portion 11a and an inflection portion 17 at the uppermost position away from the opening portion 11a. The closed end portion 15 and the open end portion 16 are communicated with each other by a lower first connecting portion 18. The open end portion 16 and the inflection portion 17 are communicated with each other by an upper second communication portion 19. The inflection part 17 and the closed end part 15 are communicated by the upper third communication part 20. The first connecting portion 18 is formed such that the distance from the closed end portion 15 toward the open end portion 16 is gradually shortened to a fixed end (a spiral base end portion 7a) of the urging member 7 described later. The second connecting portion 19 is formed such that the distance from the open end portion 16 toward the inflection portion 17 gradually increases to a fixed end (spiral base end portion 7a) of the biasing member 7 described later. The third connecting portion 20 is formed such that the distance from the inflection portion 17 toward the closed end portion 15 is gradually shortened to a fixed end (a spiral base end portion 7a) of the urging member 7 described later. . In terms of the distance to the fixed end (spiral base end portion 7a) of the urging member 7 described later, the open end portion 16 is the shortest and the inflection portion 17 is the longest.

  The second connecting portion 19 that connects the open end portion 16 and the inflection portion 17 has a groove depth gradually increased from the inflection portion 17 toward the open end portion 16. It is the deepest. As a result, a step portion 21 is provided between the open end portion 16 and the first connecting portion 18, and a pin portion (described later) dropped from the first connecting portion 18 to the open end portion 16 by the step portion 21. It is regulated that the one communication unit 18 is retrograde.

  A rail 3, a rack 4, a pinion 5, a slider 6, a biasing member 7, a one-way clutch gear 8, a first damper 9, and a second damper 10 are integrally provided on the substrate 12. That is, in the storage body of this embodiment, the rail 3, the rack 4, the pinion 5, the slider 6, the biasing member 7, the one-way clutch gear 8, the first damper 9 and the second damper 10 are first assembled to the substrate 12. The integrated product 22 is fixed to the box-shaped main body 11 and the lid 2 is attached to the box-shaped main body 11 and the like.

  The lid 2 is supported by the box-shaped main body 11 so that the opening 11a of the box-shaped main body 11 can be opened and closed. Specifically, the lid body 2 has a pivot portion 23 at the lower end, and the pivot portion 23 is pivotally supported at the lower end near the opening 11 a of the box-shaped main body 11. Thereby, the cover body 2 opens and closes the opening part 11a by rotating around the pivot part 23. In addition, the opening / closing direction of the cover body 2 is an arrow A direction in FIG. In the present embodiment, since the lid body 2 rotates about the pivot portion 23, the direction in which the lid body 2 opens and closes (A direction) is an arc direction around the pivot portion 23. Further, a lock mechanism (not shown) for locking the lid 2 to the box-shaped main body 11 of the main body 1 at a position where the opening 11a is closed is provided.

  The rail 3 has a pivot portion 24 at the lower end, and the pivot portion 24 is pivotally supported at the lower end of the substrate 12. In the storage body of this embodiment, the pivot portion 24 of the rail 3 and the pivot portion 23 of the lid body 22 are coaxial. And the leg part 25 provided in the lower end of the cover body 2 is being fixed to the lower end part of the rail 3 with the volt | bolt etc. which are not shown in figure. In addition, while attaching the said integrated product 22 to the box-shaped main body 11, and pivoting the pivot part 23 of the cover body 2 on the lower end of the box-shaped main body 11, the leg part 25 and the rail 3 of the cover body 2 are fixed. . Thereby, the rail 3 moves together with the lid body 2 as the lid body 2 opens and closes. That is, the lid 2 and the rail 3 are always interlocked.

  The rail 3 is provided with a rack 4 extending along the rail 3, and a slider 6 is held so as to be reciprocally movable along the rail 3. The means for holding the slider 6 so as to be able to reciprocate with respect to the rail 3 is not particularly limited, but a slide groove extending along the rail 3 is formed in one of the two, and the slide groove is prevented from falling off. As described above, it is possible to employ a means or the like that forms an engaging projection on the other of the two that engages with the slide groove and can reciprocate within the slide groove.

  A pinion 5 that meshes with the rack 4 is rotatably supported on the slide 6. The pinion 4 reciprocates (lifts) on the rack 4 while rotating while meshing with the rack 4, so that the slider 6 reciprocates (lifts) along the rail 3.

  The slider 6 is provided with a pin portion 26 that is engaged with and guided by the guide portion 14. One end of the urging member 7 is attached and fixed to the pin portion 26 of the slider 6. In the present embodiment, the urging member 7 is formed of a spiral spring, and the spiral base end portion 7 a is fixed in the vicinity of the lower end portion of the rail 3 that is interlocked with the lid body 2. Further, when the pin portion 26 of the slider 6 is present at the open end portion 16 of the guide portion 14, the urging member 7 is substantially in a natural state, and the urging force is hardly stored in the urging member 7. The presence or absence of the urging force of the urging member 7 when the pin portion 26 is present at the open end portion 16 is not questioned. However, if the biasing force stored in the biasing member 7 when the pin portion 26 is at the open end portion 16 is large, a large force is required when the operator returns the lid body 2 in the open state to the closed state. Therefore, the operability is reduced.

  Note that the type of the urging member 7 is not particularly limited, and a coil spring, a leaf spring, rubber, or the like may be employed. Further, the fixing positions of both ends of the biasing member 7 are not limited to those described above, and the spiral base end portion 7a is fixed to the main body 1 side (preferably, the substrate 12) instead of the rail 3 which is the lid body 2 side. Alternatively, the one end of the urging member 7 may be fixed to another portion of the slide 6 instead of the pin portion 26.

  Further, the slider 6 is a clutch that is held by the slider 6 so as to be interposed between the first damper 9 and the pinion 5 and the first damper 9, and turns on / off torque transmission between the pinion 5 and the first damper 9. The one-way clutch gear 8 is provided. The one-way clutch gear 8 is rotatably supported by the slider 6.

  The first damper 9 meshes with the pinion 5 via the one-way clutch gear 8 (for example, by meshing with a large gear of the one-way clutch gear 8 as described later) when the one-way clutch gear 8 is turned on. Then, torque is transmitted between the pinion 5 and the first damper 9 via the one-way clutch gear 8, whereby an appropriate brake is applied to the rotation of the pinion 5 and the rotation speed of the pinion 5 is reduced. The specific configuration of the first damper 9 is not particularly limited. For example, the first damper 9 may include a gear that is rotatably supported in the oil chamber. According to the first damper 9 having such a configuration, the damper function can be exhibited by reducing the rotational speed of the gear by the viscous resistance of the oil. In the storage body of the present embodiment, the first damper 9 buffers the movement of the slider 6 to buffer the opening operation of the lid 2 as will be described later.

  The one-way clutch gear 8 is turned on when the pinion 5 is rotated counterclockwise in FIGS. 1 to 4 while descending the rack 4, while the pinion 5 is elevated in the rack 4 and FIGS. 1 to 4. When it rotates in the clockwise direction, it is configured to be in an off state. If the one-way clutch gear 8 is turned off, torque is not transmitted between the pinion 5 and the first damper 9, and as a result, the first damper 9 does not function.

  The configuration of the one-way clutch gear 8 is not particularly limited as long as it is alternatively turned on or off depending on the rotation direction of the pinion 5. For example, the one-way clutch gear 8 is not limited to the rotation shaft and the rotation shaft. When the small gear that is fixed and rotates with the rotating shaft and the small gear rotates in one direction (for example, counterclockwise direction), it does not mesh with the rotating shaft, and when the small gear rotates in the other direction (for example, clockwise direction) A clutch that meshes with the rotation shaft and a large gear that is connected to the clutch and rotates together with the clutch can be provided. When the one-way clutch gear 8 having such a configuration is adopted, the pinion 5 and the small gear of the one-way clutch gear 8 are engaged with each other, and the first damper 9 and the large gear of the one-way clutch gear 8 are engaged and engaged. Thus, when the pinion 5 rotates in the clockwise direction, the small gear rotates in the counterclockwise direction, so that the one-way clutch gear 8 can be turned off, and the pinion 5 rotates in the counterclockwise direction. When this is done, the small gear rotates in the clockwise direction, so that the one-way clutch gear 8 can be turned on.

  Furthermore, the storage body of the present embodiment includes a second damper 10 having one end coupled to the vicinity of the upper end of the rail 3 and the other end coupled to the substrate 12 on the main body 1 side.

  The type of the second damper 10 is not particularly limited, and for example, a shock absorber can be employed. In the storage body of the present embodiment, the second damper 10 buffers the movement of the rail 3 to buffer the closing operation of the lid 2 as will be described later.

  The storage body of the present embodiment having the above configuration operates as follows.

  As shown in FIG. 1, the pin portion 26 of the slider 6 to which one end of the urging member 7 is attached is the guide portion 14 in a state where the lid 2 is disposed at the closed position (closed state) by a lock mechanism (not shown). Is located at the closed end 15. At this time, the urging member 7 is expanded and contracted by a predetermined amount from the natural state, and a predetermined urging force is accumulated in the urging member 7. Further, in this closed state, the slider 6 is located near the upper end of the rail 3 and is in the raised position with respect to the rail 3.

  When the lock is released by operating a lock mechanism (not shown) in this closed state, the lid 2 is moved downward about the pivot portion 23 (the timepiece of FIG. 1) by the urging force of the urging member 7 and the weight of the lid 2. Rotate in the rotation direction) and start opening the opening 11a. When the lid body 2 is rotated, the rail 3 fixed to the leg portion 25 of the lid body 2 is interlocked with the lid body 2 and the rail 3 is rotated in the clockwise direction in FIG. Then, the pin portion 26 of the slider 6 held so as to be reciprocally movable with respect to the rail 3 is guided to the guide portion 14 of the main body 1, so that the pin portion 26 extends along the first communication path 18 of the guide portion 14. While moving to the open end portion 16, the pinion 5 that is pivotally supported by the slide 6 and the rack 4 provided on the rail 3 are engaged, so that the pinion 5 moves down on the rack 4 and the slider 6 moves along the rail 3. (The open state shown in FIG. 2). At this time, the pinion 5 is lowered on the rack 4 while rotating counterclockwise in FIG. 1 due to meshing with the rack 4, so that the one-way clutch gear 8 is turned on, and the pinion 5 is connected via the one-way clutch gear 8. And the first damper 9 mesh with each other. Then, torque is transmitted between the pinion 5 and the first damper 9 via the one-way clutch gear 8, whereby an appropriate brake is applied to the rotation of the pinion 5 and the rotation speed of the pinion 5 is reduced. As a result, the first damper 9 functions to buffer the opening operation of the lid body 2 and eliminate the impact associated with the opening operation.

  In the process in which the lid 2 is changed from the closed state to the open state, the pin portion 26 of the slider 6 moves from the closed end portion 15 to the open end portion 16 along the first communication path 18 of the guide portion 14. Since the distance from the closed end portion 15 toward the open end portion 16 toward the fixed end of the biasing member 7 (the spiral base end portion 7a) is gradually shortened, the pin portion 26 is connected to the first connecting path 18 in the first connection path 18. As it moves from the closed end 15 to the open end 16 along the path 18, the biasing member 7 contracts while gradually releasing the biasing force. When the pin portion 26 of the slider 6 is in the open state, the distance between the pin portion 26 of the slider 6 and the fixed end (spiral base end portion 7a) of the biasing member 7 in the guide portion 14 is the shortest. The urging member 7 is almost in a natural state, and the urging force 7 hardly stores the urging force.

  When the lid 2 is returned from the open state to the closed state, first, the operator manually lifts the lid 2 upward so that the lid 2 is centered on the pivot portion 23 (counterclockwise direction in FIG. 1). ) To rotate. When the lid body 2 rotates, the rail 3 fixed to the leg portion 25 of the lid body 2 is interlocked with the lid body 2 and the rail 3 rotates about the pivot portion 24 in the counterclockwise direction of FIG. Then, the pin portion 26 of the slider 6 held so as to be reciprocally movable with respect to the rail 3 is guided to the guide portion 14 of the main body 1, so that the pin portion 26 extends along the second communication path 19 of the guide portion 14. While moving toward the inflection part 17, the pinion 5 is pivoted on the slide 6 and the rack 4 provided on the rail 3 is engaged, so that the pinion 5 rises on the rack 4 and the slider 6 moves to the rail 3. Ascend along. At this time, the pinion 5 moves upward on the rack 4 while rotating clockwise in FIG. 1 due to the meshing with the rack 4, so that the one-way clutch gear 8 is turned off. For this reason, the first damper 9 does not function when the lid 2 is closed.

  In the first stage of the process in which the lid 2 is changed from the open state to the closed state (the phase in which the lid 2 is rotated upward by the operator's operating force), the pin portion 26 of the slider 6 is connected to the second contact of the guide portion 14. It moves from the open end portion 16 to the inflection portion 17 along the path 19. Since the distance from the open end portion 16 to the inflection portion 17 of the second communication path 19 is gradually increased, the pin portion 26 has a first end portion. The urging member 7 gradually expands as it moves from the open end portion 16 to the inflection portion 17 along the two communication paths 19, and the urging force is gradually stored in the urging member 7. Then, the lid body 2 is rotated upward until the pin portion 26 reaches the inflection portion 17 of the guide portion 14 (in the middle of closing in FIG. 3), and then the pin portion 26 passes over the inflection portion 17 and the guide portion 14. When entering the third communication path 20, the third communication path 20 is closed from the inflection portion 17 having the longest distance from the guide portion 14 to the fixed end (spiral base end portion 7 a) of the biasing member 7. Since the distance to the fixed end (spiral base end portion 7 a) of the biasing member 7 is gradually shortened toward the end portion 15, the pin portion 26 is bent along the third communication path 20. As it moves from the portion 17 to the closed end portion 15, the biasing member 7 gradually contracts while releasing the biasing force. For this reason, if the operator rotates the lid 2 upward (counterclockwise direction in FIG. 1) until the pin part 26 exceeds the inflection part 17, even if the operator releases the operation force thereafter. The lid body 2 is rotated upward by the urging force of the urging member 7 and returns to the closed state of FIG.

  In a later stage of the process in which the lid body 2 is changed from the open state to the closed state (a stage in which the lid body 2 is closed by the urging force of the urging member 7), the second damper 10 functions to close the lid body 2. The shock associated with the closing operation can be eliminated by buffering the operation.

  Thus, when the lid 2 returns from the open state to the closed state, the pin portion 26 of the slider 6 is located at the closed end portion 15 of the guide portion 14, and a predetermined urging force is accumulated in the urging member 7 again. Therefore, the urging member 7 can urge the opening operation of the lid body 2 performed thereafter.

  Thus, in the storage body of the present embodiment, the urging force is accumulated in the urging member 7 by the closing operation of the lid 2, and the opening operation and the closing operation of the lid 2 are performed by the accumulated urging force. Some are energized. Thus, since the opening and closing operations of the lid 2 can be performed using the biasing force accumulated in advance with the opening and closing movement of the lid 2, it is necessary to provide an expensive drive source such as a motor separately. Absent. For this reason, it is possible to easily open and close the lid 2 with a simple configuration without using a motor. Therefore, it is possible to prevent an increase in cost due to the use of an expensive drive source such as a motor.

  Further, by appropriately setting the shape of the guide portion 14, the strength, timing, and the like for biasing the opening / closing movement of the lid 2 can be set as desired, and the degree of freedom in design is increased.

  Furthermore, in the storage body of the present embodiment, the opening operation of the lid body 2 can be buffered by the first damper 9 and the closing operation of the lid body 2 can be buffered by the second damper 10. The impact at the time of operation and closing can be eliminated. For this reason, the opening operation and closing operation of the lid 2 are smooth.

  In addition, in the storage body of this embodiment, torque transmission between the pinion 5 and the first damper 9 is turned on / off by the one-way clutch gear 8 that is pivotally supported by the slider 6, so that the operation of the one-way clutch gear 8 is stable. And be quiet.

  Further, in the storage body of the present embodiment, the guide 12, the rail 3 provided with the rack 4, the pinion 5, and the one-way clutch gear 8 are attached to the substrate 12 that can be attached to the box-shaped main body 11 of the main body 1 by retrofitting. A slider 6 for holding the first damper 9, a biasing member 7, and a second damper 10 are provided. For this reason, in a state where these members are provided on the substrate 12, it is possible to confirm whether or not these members operate properly or to adjust them so as to operate appropriately. Therefore, it is possible to easily check and adjust the operation of these members. Moreover, since it is not necessary to attach each of these members separately with respect to the main body 1, attachment work becomes easy. Furthermore, since the said operation | movement adjustment can be performed by removing the base material 12 from the box-shaped main body 11 of the main body 1, a maintenance operation | work also becomes easy.

(Embodiment 2)
The storage body of this embodiment shown in FIGS. 6 and 7 employs a movable clutch gear 27 instead of the one-way clutch gear 8.

  That is, the long hole 28 extending in a predetermined direction and a predetermined length is formed in the slider 6 according to this embodiment. The shaft portion 27 a of the movable clutch gear 27 is engaged with the elongated hole 28, so that the movable clutch gear 27 is held by the slider 6 so as to be able to reciprocate while rotating in the elongated hole 28. Thus, the movable clutch gear 27 held by the slider 6 is always meshed with the pinion 5 by engaging the shaft portion 27a with the long hole 28. The movable clutch gear 27 is engaged with the first damper 9 when the shaft portion 27a is positioned on one end side of the elongated hole 28 (the lower side in FIG. 6, the first damper 9 side). The part 27a moves from one end side to the other end side of the long hole 28, so that the first damper 9 is separated.

  In the storage body of this embodiment, the torque transmission between the pinion 5 and the first damper 9 is turned on / off when the movable clutch gear 27 reciprocates in the long hole 28 by meshing with the pinion 5.

  That is, when the lid body 2 is opened, the pinion 5 is lowered on the rack 4 while rotating counterclockwise in FIG. 6 due to meshing with the rack 4, so that the movable clutch gear 27 meshed with the pinion 5 is engaged. 6 rotates in the clockwise direction in FIG. 6, and the shaft portion 27 a of the movable clutch gear 27 moves in the elongated hole 28 from the other end side (upper side in FIG. 6, the pinion 5 side) to one end side. Then, the movable clutch gear 27 and the first damper 9 mesh with each other, and torque is transmitted between the pinion 5 and the first damper 9 via the movable clutch gear 27. As a result, the first damper 9 functions to buffer the opening operation of the lid body 2 and eliminate the impact associated with the opening operation.
