Description

  The present invention relates to an extrusion device for assisting movement of a slider in a slide device including a base and a slider, and a slide device including the extrusion device.

  In recent storage units such as system kitchens, an extrusion device called "push-open type" is provided to assist the operation of pulling out the storage case such as a drawer from the cabinet and improve its usability. Usually, in a system kitchen having a storage unit equipped with such an extrusion device, when the drawer is pushed into the cabinet, a light pressure is applied to the front of the drawer to apply this pressure. The pressure is a switch, and the drawer is pushed forward.

  That is, by providing such an extrusion device, even if both hands are blocked by an object to be stored such as a dish or a small object, the drawer is pushed out simply by applying light pressure to the front surface of the drawer with the elbow, leg or buttocks. It is very convenient to use, and the work for storing the objects to be stored becomes simple.

  As such an extrusion device, for example, a pop-out device having a structure as described in Patent Document 1 has been proposed.

JP 2004-121623 A

  The pop-out device described in Patent Document 1 includes a pop-out mechanism that is attached to a frame body such as a cabinet, a front roller that is attached to the front side of the attached body such as a drawer, and a rear roller that is attached to the rear side of the attached body. The arm body engaged with the front roller, biasing means for applying a biasing force to the arm body, movement blocking means for blocking the movement of the arm body, and the arm body of the movement blocking means Release means for releasing the engagement is provided.

  Here, the operation of the pop-out device will be described. In a state where the mounted body is housed in the frame (closed state), the movement of the arm body is blocked by the movement blocking means.

  When the user applies a light pressure to the front surface of the mounted body, the release means releases the engagement between the movement preventing means and the arm body by the pressure, and the arm body rotates by the urging force of the urging means. Then, as it gets up and is pulled to push out the front roller, the mounted body to which the front roller is attached pops out from the frame.

  Subsequently, when the user further pulls out the attached body from the frame body, the rear roller contacts from behind the arm body, but the arm body is structured to bend forward with respect to the load from behind. Therefore, the rear roller quickly passes through the bent arm body, and the attached body is sufficiently pulled out (open state).

  On the other hand, when the attached attached body is pushed back toward the frame body, the rear roller contacts from the front of the arm body.

At this time, since the arm body has a structure that does not bend with respect to a load from the front, the arm body is pushed back by the rear roller in this state, but finally the arm body is pushed back. Since the arm body engages with the movement preventing means and rotates and tilts, the rear roller further moves backward so as to pass through the end of the tilted arm body, and then the mounted body is completely attached to the frame body. By pushing back, the original state is restored.

  In other words, in the extrusion device (pumping device) having such a conventional configuration, the arm body is given a complicated motion such as a rotational motion independent of the back-and-forth movement so as not to hinder the movement of the rear roller. There is a need to.

  However, imparting such a complicated movement to the arm body inevitably tends to reduce the mounting strength of the arm body. On the other hand, the arm body is the most suitable in this type of extrusion device. Since it is a part to which a load is applied, there is a problem in that long-term stable operation cannot be secured due to damage or deformation caused by repeated use, or so-called looseness.

  In addition, in order to require such a complicated movement of the arm body, there arises a problem of an increase in the number of parts and a manufacturing cost associated therewith.

  Therefore, as a result of intensive studies to solve such problems, the present inventor is an extrusion device for assisting the movement of the slider in the slide device including the base portion and the slider, and the extrusion device is an extrusion device. A member, a return member that moves along a fixed movement path, an urging means for applying an urging force to the movement of the push member and the return member, a movement preventing means for preventing movement of the push member and the return member, An extruding mechanism comprising releasing means for releasing the movement preventing means, a member to be pushed out by the pushing member in the pushing mechanism, and a return for returning the movement preventing means from the invalid state to the valid state by pushing back the reset member. In particular, when the extrusion device is attached to the slide device, it is recovered according to the movement in the direction of returning to the base of the slider. An extrusion apparatus (hereinafter referred to as the apparatus of the present invention) characterized by imparting a continuous or stepwise inclination to the movement path so that the member moves away from the return member continuously or stepwisely is completed. It was.

  That is, the inventor of the present invention, as an extrusion device for assisting the movement of the slider in the slide device composed of this kind, base and slider, the member to be restored is continuously or in accordance with the movement in the direction in which the slider returns to the base. It has been found that if an extruding mechanism having a moving path away from the return member step by step is adopted, the extruding mechanism has a very simple and robust structure and can realize a long-term stable operation.

  In addition, it has been found that if such a configuration is adopted for the extrusion mechanism, the number of parts can be reduced and the manufacturing cost can be reduced.

  The present invention has been completed on the basis of the above knowledge, a novel extrusion device capable of maintaining a stable operation over a long period of time with a simple structure and low manufacturing cost, and a slide provided with this extrusion device. An object is to provide an apparatus.

The device of the present invention, which is a means for solving the above problems, is an extrusion device for assisting the movement of the slider in the slide device composed of a base and a slider, and the extrusion device moves the extrusion member along a certain movement path. A return member, an urging means for applying an urging force to the movement of the push member and the return member, a movement prevention means for preventing the movement of the push member and the return member, and a release means for releasing the movement prevention means An extruding mechanism comprising a releasing means, an extruding member to be pushed out by an extruding member in the extruding mechanism, and a return member for returning the movement preventing means from an invalid state to an effective state by pushing back the resetting member. In attaching the extrusion device to the slide device, the return member is continuously or stepped according to the movement in the direction of returning to the base of the slider. Manner away from the return member, and wherein the applying a continuous or stepwise gradient in the movement path.
Hereinafter, the apparatus of the present invention will be described in detail.

  The device of the present invention is an extrusion device for assisting the movement of the slider in a slide device comprising a base and a slider, and the slide device moves back and forth (sliding) along the inside or outside of the base. If it is, it will not specifically limit, For example, the storage apparatus etc. which a storage case, such as drawer | drawing-out as a slider, moves back and forth can be mentioned, for example, using frame bodies, such as a cabinet, as a base.

  The device of the present invention is for assisting the movement of the slider in the slide device, and the device comprises an “extrusion mechanism”, an “extruded member”, and a “return member”.

  The push-out mechanism includes a push-out member, a return member that moves along a fixed movement path, a biasing means for applying a biasing force to the movement of the push-out member and the return member, and blocking the movement of the push-out member and the return member. The movement preventing means, and the releasing means for releasing the movement preventing means. In such an extruding mechanism, the state where the movement of the pushing member and the return member is blocked by the movement preventing means is the state of the origin. When the movement preventing means in the valid state is invalidated by the releasing means, the urging force by the urging means is applied to the pushing member and the returned member, and the pushing member and the returned member move, When the pushing member and the return member are returned to the origin, the movement preventing means becomes effective, and the movement of the pushing member and the return member is blocked.

  In the device of the present invention, the push member and the return member are not only configured as independent members (parts), but the push member and the return member can be configured as a common member (part) if desired. In this case, the pushing member also serves as a member to be restored.

  Further, the urging means for applying the urging force to the movement of the push-out member and the return member in the apparatus of the present invention is not particularly limited, and a plurality of independent push members and return members are provided. However, a known elastic means such as a coil spring or a spiral spring may be appropriately selected and used, but the operating point moves more than a coil spring that generates a linear urging force. Thus, it is preferable to use a spiral spring in which the direction of the urging force is changed, because it is possible to appropriately adjust the labor required to return the extrusion mechanism to the origin against the urging force.

  Further, the member to be extruded is pushed out in contact with the pushing member in the pushing mechanism and transmits the stress to the slider (or base) to move the slider.

  Furthermore, the return member returns the push-out mechanism to the original state by contacting and pushing back the return member in the push-out mechanism according to the movement in the direction of returning to the base of the slider.

  That is, the apparatus of the present invention assists the movement of the slider by extruding the member to be extruded by the extruding mechanism and transmitting this stress to the slider (or the base). It returns to the state of.

  Here, regarding the attachment of the device of the present invention to the slide device, while mainly attaching the extrusion mechanism to the base, the method of attaching the extruded member and the return member to the slider, while attaching the extrusion mechanism to the slider, the extruded member and There are two methods of attaching the return member to the base, and it is only necessary to determine which one is adopted, and it is not possible to generally give a superiority or inferiority. It is generally preferable to attach a large extrusion mechanism to the base side because it does not hinder the stable operation of the slide device.

  By the way, in the device of the present invention, the state where the movement of the pushing member and the return member is blocked by the movement blocking means is the state of the origin, and when the movement blocking means becomes invalid by the releasing means, the biasing force by the biasing means Is applied to the extruding member and the return member, and the extruding member moves to contact (engage) the extruding member, and the slider to which this stress is transmitted moves, but if the slider further moves, the returning member Will come into contact with the return member, and further movement of the slider will be hindered.

  Further, if the return member does not pass beyond the return member, the return member cannot thereafter return the push-out mechanism to the original state.

  Therefore, in the device of the present invention, the return member and / or the return member is moved or deformed according to the contact between the return member and the return member during the movement of the slider in the direction away from the base, and the slider It is necessary not to disturb the continuation of exercise.

  Here, the means for moving or deforming the return member and / or the return member so as not to prevent the continuation of the movement of the slider is not particularly limited, but specifically, for example, the return member. The return member and / or the return member is configured to bend (rotate) according to the contact between the return member and the return member, or the contact portion of the return member or the return member is provided with a taper. For example, a method may be used in which the return member and the return member pass each other.

  It should be noted that it is only necessary to appropriately determine which of the return member and the return member can be moved or deformed, and it cannot be generally superior or inferior, but the structure of the return member that is relatively loaded is simplified. In order to maintain the physical strength, it is generally preferable that the return member is configured to move or deform.

  In the apparatus of the present invention, when the push-out mechanism is attached to the slide device, the returned member is moved away from the return member continuously or stepwise according to the movement in the direction of returning to the base of the slider. It has the greatest feature in that a continuous or stepwise inclination is given to the movement path of the member.

  That is, in this type of extrusion device, the return member returns the push-out mechanism to the original state in accordance with the movement in the direction of returning to the base of the slider, and the movement preventing means is returned from the invalid state to the valid state. However, after the pushing mechanism is returned to the original state, it is necessary that the return member does not hinder the next movement of the pushing mechanism.

  Therefore, in the above-mentioned Patent Document 1, the arm body is configured to rotate and tilt when the arm body returns to the origin, and the rear roller can pass through the end of the arm body. However, if such an intricate movement is imparted to the arm body, the strength is reduced. On the other hand, the arm body is the most burdensome part in this type of extrusion device, and therefore it is not damaged or deformed by repeated use. There arises a problem that long-term stable operation cannot be ensured due to the occurrence of so-called looseness.

  In this regard, in the device of the present invention, when the push-out mechanism is attached to the slide device, the return member is moved away from the return member continuously or stepwise according to the movement in the direction of returning to the base of the slider. Since the movement path of the member is given a continuous or stepwise inclination with respect to the movement direction of the slider, the returned member can be continuously moved by simply moving the returned member along the movement path. After returning from the return member in steps or steps and returning the pushing mechanism to the original state, the returning member quickly passes through the end of the returned member. The structure is simple and sturdy, and long-term stable operation can be realized.

  The movement path of the return member may be any of a linear movement path, a curved movement path, and a bent movement path. After all, the return member that is pushed by the return member and returns to the movement path is continuous. After returning from the return member in steps or steps and returning to the origin, the return member may pass through the end of the return member promptly.

  The slide device of the present invention is characterized by comprising the device of the present invention, and as this slide device, the slider moves back and forth (slide motion) along the inside or outside of the base. Although not particularly limited, specific examples include a storage device in which a storage case such as a drawer as a slider moves back and forth with a frame such as a cabinet as a base.

  The slide device provided with the device of the present invention can be configured such that by applying a light pressure to the front surface of the slider or the like, this pressure becomes a switch and the slider is pushed forward. Even if both hands are blocked by an object, the drawer is pushed out simply by applying light pressure to the front of the drawer with the elbows, legs or buttocks, etc., so it is very easy to use and the work for storing the items to be stored becomes simple. is there.

  The present invention is a novel extruding apparatus having the above-described configuration, having a simple structure and low manufacturing cost, and capable of maintaining a stable operation over a long period of time, and a sliding apparatus including the extruding apparatus.

  That is, in the apparatus of the present invention, when the extrusion mechanism is attached to the slide device, the return member is separated from the return member continuously or stepwise according to the movement in the direction of returning to the base of the slider. Since the moving path is given a continuous or stepwise inclination with respect to the moving direction of the slider, the resetting member can be continuously or simply moved only by moving along the moving path. After stepping away from the return member and returning the push-out mechanism to the original state, the return member quickly passes through the end of the return member, which makes the push-out mechanism very simple and It has a sturdy structure and can achieve long-term stable operation.

  In addition, since the apparatus of the present invention employs such a configuration, the number of parts is reduced and the manufacturing cost can be reduced.

  On the other hand, the slide device of the present invention comprises the device of the present invention, and is configured such that when a light pressure is applied to the front surface of the slider or the like, this pressure becomes a switch and the slider is pushed forward. Therefore, even if both hands are blocked by the object to be stored, the drawer is pushed out by simply applying light pressure to the front of the drawer with the elbows, legs or buttocks, etc. The work to do becomes simple.

  Examples of the present invention will be described below, but the present invention is not limited to these examples.

  FIG. 1 is a schematic diagram ((a) front view, (b) right side view) showing an extrusion mechanism 2 in an extrusion apparatus 1 of the present invention related to Example 1. The extrusion mechanism 2 is an extrusion mechanism main body 26. , A pushing member 21 that moves along a linear guide as the moving path 22, a pulling spring as a biasing means 23 for applying a biasing force to the movement of the pushing member 21, and the movement of the pushing member 21 is blocked. The movement prevention means 24 and the release means 25 for releasing the movement prevention means 24 are included.

  In the pushing mechanism 2, the state where the pushing member 21 is engaged with the movement preventing means 24 and the movement is blocked is indicated by the origin (indicated by a solid line). When the pressure is applied from the direction, the engagement between the movement preventing means 24 and the pushing member 21 is released and the urging force by the urging means 23 is given to the pushing member 21, and the pushing member 21 moves along the movement path 22. (Denoted by a broken line).

  On the other hand, when the pushing member 21 is returned to the origin against the urging force of the urging means 23, the movement preventing means 23 and the pushing member are engaged again, and the pushing member 21 is prevented from moving.

  That is, in the push-out mechanism 2 according to the first embodiment, the push-out member 21 and the return member are configured by a common member so that the push-out member 21 also serves as the return member.

  FIG. 2 is a schematic diagram ((a) front view, (b) side view) showing a member 3 to be extruded in the extrusion apparatus 1 of the present invention related to Example 1. In this example, a certain thickness is shown. A certain block body is adopted as the extruded member 3.

  FIG. 3 is a schematic diagram ((a) front view, (b) side view) of the return member 4 in the extrusion apparatus 1 of the present invention related to Example 1. The return member 4 in this example is a spring coil. Normally, the state indicated by a solid line is maintained by No. 41, but when a load is applied from the direction B in the figure, it is rotated in a direction to release the load and deformed to the state indicated by a broken line. .

  FIG. 4 is a schematic view showing the slide device 5 of the present invention comprising the extrusion device 1 of the present invention comprising the extrusion mechanism 2, the extruded member 3 and the return member 4, and the extrusion provided in the slide device 5. The base 51 and the slider 52 in the slide device 5 are shown in a transparent state so that the device 1 can be seen.

  In addition, about the attachment of the extrusion apparatus 1 with respect to the slide apparatus 5 in a present Example, while attaching the extrusion mechanism 2 to the base 51, the to-be-extruded member 3 and the return member 4 are attached to the slider 52. FIG.

  In particular, when the extrusion device 1 is attached to the base 51, the movement path 22 in the extrusion device 1 is attached so as to be inclined with respect to the movement direction of the slider 52, that is, in a direction returning to the base 51 of the slider 52. The pushing member 21 (the member to be restored) pushed by the return member 4 is attached so as to gradually move away from the return member 4 in accordance with the movement of.

  On the other hand, when attaching the extruded member 3 and the return member 4 to the slider 52, the extruded member 3 is provided at the front part of the slider 52 in the advancing direction, and the return member 4 is provided at the rear part thereof. At this time, the pushing member 21 in the pushing mechanism 2 is disposed so as to be sandwiched between the pushed member 3 and the return member 4.

  Here, the operation state of the slide device 5 including the extrusion device 1 will be described with reference to the drawings. The state in which the slider 52 is accommodated in the base 51 and the movement of the extrusion member 21 is blocked by the movement blocking means 23 is shown. This is the state of the origin (FIG. 5A).

  When the pressure is applied to the front surface of the slider 52, the releasing means 25 is pushed in, the engagement between the movement preventing means 23 and the pushing member 21 is released, and the pushing member 21 in which the movement preventing means 24 becomes invalid is biased. In response to the urging force of the means 23, the member 3 moves along the movement path 22 while pushing the member 3 to be extruded (FIG. 5B).

  When the slider 52 further moves, the return member 4 comes into contact with the pushing member 21 from the rear in the figure. When a load is applied from the front in the figure, the return member 4 rotates and deforms in a direction to release the load. Thus, the return member 4 promptly passes through the pushing member 21 (FIG. 5C), and the movement of the slider 52 continues to the final state without being hindered (FIG. 5D).

  On the other hand, when the slider 52 is pushed toward the base 51 from the state in which the slider 52 has advanced, the return member 4 comes into contact with the push member 21 (recovered member) from the front in the drawing (FIG. 6A).

  However, since the return member 4 has a structure that does not move / deform in response to a load from the rear in the figure, the return member 4 continues to push the pushing member 21 (recovered member) as it is (FIG. 6B). .

  At this time, the push-out member 21 (reset member) pushed by the return member 4 continuously moves along the movement path 22 provided with an inclination away from the return member 4, so that the push member 21 gradually returns from the return member 4. Come away.

  The return member 4 slips through the end of the push member 21 (recovered member) after the point where the push member 21 can be engaged with the movement preventing means 23, thereby preventing the push member 21 from moving. It engages with the means 23 and returns to the original state again (FIG. 6C).

  FIG. 7 is a schematic view showing a slide device 5 of the present invention comprising the extrusion device 1 of the present invention comprising the extrusion mechanism 2, the member to be extruded 3 and the return member 4 in another arrangement, and inside the slide device 5. The base 51 and the slider 52 in the slide device 5 are shown in a transmissive state so that the extrusion device 1 provided for the above can be visually recognized.

  In addition, about the attachment of the extrusion apparatus 1 with respect to the slide apparatus 5 in a present Example, while attaching the extrusion mechanism 2 to the slider 52, the to-be-extruded member 3 and the return member 4 are attached to the base 51.

  In particular, when the extrusion device 1 is attached to the slider 52, the movement path 22 in the extrusion device 1 is attached so as to be inclined with respect to the movement direction of the slider 52, that is, in a direction returning to the base 51 of the slider 52. The pushing member 21 (the member to be restored) pushed by the return member 4 is attached so as to gradually move away from the return member 4 in accordance with the movement of.

  On the other hand, when attaching the extruded member 3 and the return member 4 to the base portion 51, the slider 52 is provided with the return member 4 at the front part in the advancing direction, the rear part with the extruded member 3, and the extrusion mechanism 2 is in the state of the origin. At this time, the pushing member 21 in the pushing mechanism 2 is disposed so as to be sandwiched between the pushed member 3 and the return member 4.

  Here, the operation state of the slide device 5 including the extrusion device 1 will be described with reference to the drawings. The state in which the slider 52 is accommodated in the base 51 and the movement of the extrusion member 21 is blocked by the movement blocking means 23 is shown. This is the state of the origin (FIG. 8A).

  When the pressure is applied to the front surface of the slider 52, the releasing means 25 is pushed in, the engagement between the movement preventing means 23 and the pushing member 21 is released, and the pushing member 21 in which the movement preventing means 23 becomes invalid is biased. In response to the urging force of the means 23, the member 3 moves along the movement path 22 while pushing the member 3 to be extruded (FIG. 8B).

  When the slider 52 further moves, the pushing member 21 comes into contact with the return member 4 from the rear side in the figure. When a load is applied from the rear side in the figure, the return member 4 rotates and deforms in a direction to release the load. Thus, the pushing member 21 quickly passes through the return member 4 (FIG. 8C), and the movement of the slider 52 continues to the final state without being hindered (FIG. 8D).

  On the other hand, when the slider 52 is pushed toward the base 51 from the state in which the slider 52 has advanced, the pushing member 21 (recovered member) comes into contact with the returning member 4 from the front in the drawing (FIG. 9A).

  However, since the return member 4 has a structure that does not move / deform in response to a load from the front in the figure, the pushing member 21 (recovered member) continues to push the return member 4 as it is (FIG. 9B). .

  At this time, the pushing member 21 (reset member) that pushes the return member 4 continuously moves along the moving path 22 having an inclination away from the return member 4, and thus gradually moves away from the return member 4. .

  The return member 4 slips through the end of the push member 21 (recovered member) after the point where the push member 21 can be engaged with the movement preventing means 23, thereby preventing the push member 21 from moving. It engages with the means 23 and returns to the original state again (FIG. 9C).

  FIG. 10 is a schematic diagram illustrating the extrusion mechanism 2 in the extrusion apparatus 1 of the present invention according to the third embodiment. The extrusion mechanism 2 moves along a bending guide as the extrusion mechanism main body 26 and the movement path 22. From the pushing member 21, the biasing means 23 for applying a biasing force to the movement of the pushing member 21, the movement blocking means 24 for blocking the movement of the pushing member 21, and the releasing means 25 for releasing the movement blocking means 24 It will be.

  That is, the extrusion mechanism 2 in the extrusion apparatus 1 according to the present embodiment is the same as that described in the first embodiment except that the movement path 22 is bent. In the first embodiment, the movement path 22 is Since the extrusion member 21 (recovered member) is continuously separated from the return member 4 because it is linear, when the extrusion mechanism 2 having such a bent movement path 22 is used, the extrusion member 21 (recovered member). The return member) moves away from the return member 4 step by step.

  The rest is the same as in the first embodiment, and the description is omitted here to avoid repetition.

  FIG. 11 is a schematic diagram showing an extrusion mechanism 2 in the extrusion apparatus 1 of the present invention related to Example 4. The extrusion mechanism 2 moves along a curved guide as an extrusion mechanism body 26 and a movement path 22. The pushing member 21, the biasing means 23 for applying a biasing force to the movement of the pushing member 21, the movement preventing means 24 for blocking the movement of the pushing member 21, and the releasing means 25 for releasing the movement preventing means 24. It consists of

  That is, the extrusion mechanism 2 in the extrusion apparatus 1 of the present invention according to the present embodiment is the same as that described in the first embodiment except that the movement path 22 is curved. In the first embodiment, the movement path 22 is the same. Since the extruding member 21 (recovered member) gradually moves away from the returning member 4 (constant speed), the extruding mechanism 2 having such a curved moving path 22 is used. In this case, since the inclination of the slider 52 with respect to the moving direction gradually increases, the pushing member 21 (recovered member) is quickly separated from the returning member 4 (accelerated).

  The rest is the same as in the first embodiment, and the description is omitted here to avoid repetition.

  FIG. 12 is a schematic diagram showing the extrusion mechanism 2 in the extrusion apparatus 1 of the present invention according to Example 5 ((a) a view with the cover 28 removed, (b) a view with the cover 28), and this extrusion mechanism. Reference numeral 2 denotes an extruding mechanism body 26, an extruding member 21 and a returnable member 27 that move along a linear guide as the moving path 22, and an attachment for applying a biasing force to the movement of the extruding member 21 and the returnable member 22. A spiral spring as the urging means 23, an arm 29 for transmitting the urging force of the urging means 23 to the pushing member 21 and the return member 22, a movement preventing means 24 for preventing the pushing member 21 from moving, and the movement preventing means 24 is composed of release means 25 for releasing 24.

  In this push-out mechanism 2, the state in which the push-out member 21 and the return member 27 are engaged with the movement blocking means 24 and the movement is blocked is indicated by the origin (indicated by a solid line). When pressure is applied to the part from the direction A in the figure, the engagement between the movement preventing means 24 and the pushing member 21 (and the return member 27) is released, and the urging force by the urging means 23 is applied to the pushing member 21 (and the pushed member). This is given to the return member 27), and the pushing member 21 (and the returned member 27) moves along the movement path 22 (indicated by a broken line).

  On the other hand, when the returned member 27 (and the pushing member 21) is returned to the origin against the urging force of the urging means 23, the movement preventing means 23 and the returned member 27 (and the pushing member 21) are engaged again, The movement of the return member 27 (and the pushing member 21) is prevented.

  That is, in the extrusion mechanism 2 according to the present embodiment, the extrusion member 21 and the return member 27 are configured to exist in independent parts.

  In the extrusion mechanism 2 according to the present embodiment, a spiral spring is used as the urging means 23, and the action point moves to change the direction of the urging force. Therefore, the extrusion mechanism 2 resists the urging force. Therefore, it is possible to appropriately adjust the labor required for returning the state to the original state.
