Description

  The present invention relates to an interactive footwear such as slippers and sandals that can be worn from either one of the longitudinal sides of a substrate on which a foot is placed and the other side of the other.

  Conventionally, as this type of bi-directional footwear, for example, one described in Patent Document 1 (Japanese Utility Model Laid-Open No. 7-5402) is known. As shown in FIG. 17, the two-way footwear Sa has a base plate 100 on which a foot is placed and a longitudinal intermediate portion of the base plate 100 that is bridged between both side portions 101 of the base plate 100 and covers the back of the foot when used. The upper shell body 102 is provided. The upper body 102 can be tilted with the width direction orthogonal to the longitudinal direction of the substrate 100 as an axis, so that both ends 103 thereof have metal pins 104 having axes along the width direction. It is attached to the side part 101 of.

  When the bidirectional footwear Sa is used, the foot is inserted into the space formed between the substrate 100 and the upper body 102 from one side or the other side in the longitudinal direction of the substrate 100, and the foot is inserted into the substrate 100. To be placed. When the foot is placed, the upper body 102 is pushed by the instep of the inserted foot, and tilts with the pin 104 as the tilting axis on the side opposite to the side through which the foot is inserted. Therefore, since the upper body 102 tilts as described above regardless of whether the two-way footwear Sa is worn from one side or the other side in the longitudinal direction of the substrate 100, a large number of people such as hospitals and hotels When the footwear Sa is taken off at a place where the footwear enters and exits, it is not necessary to change the direction of the footwear Sa so that the next user can easily wear it, which is very convenient.

Japanese Utility Model Publication No. 7-5402

  However, in this conventional bidirectional footwear Sa, when the upper body 102 is tilted by inserting the foot into the space formed between the substrate 100 and the upper body 102, the upper body 102 swings to the left and right. There was a problem that it was easily wobbled and sometimes difficult to wear.

  The present invention has been made in view of such problems, and an object of the present invention is to provide a bi-directional footwear in which the upper body is less likely to wobble and the ease of wearing is improved.

  In order to achieve such an object, the bi-directional footwear of the present invention has a substrate on which a foot is placed and an intermediate portion in the longitudinal direction of the substrate that is bridged on both sides of the substrate and covers the back of the foot in use. In a bi-directional footwear comprising a covering upper body, wherein both ends of the upper body are attached to the substrate so as to be tiltable about a width direction orthogonal to the longitudinal direction of the substrate as an axis. A guide means for guiding the upper body when the upper body is tilted is provided.

  Thus, when putting on this bidirectional footwear, the foot is placed on the substrate by inserting the foot into the space formed between the substrate and the upper body from one side or the other side in the longitudinal direction of the substrate. Let When the foot is placed on the substrate, the instep body is pushed by the inserted instep of the foot and tilts with the width direction as the axis on the side opposite to the side through which the foot is inserted. At this time, the upper body is tilted while being guided by the guide means, and therefore, the situation where the upper body swings to the left and right is suppressed, and the upper body is tilted smoothly. That is, since the upper body is guided by the guide means regardless of which side of the substrate is worn from one side or the other side in the longitudinal direction, the ease of wearing is improved.

  If necessary, the guide means includes a guided portion provided on the upper body and moving with the upper body, and a guide portion that guides the guided portion so as to be movable. Yes. As a result, the guided portion is guided by the guide portion, and this guided portion moves together with the upper body, so that the upper body is guided by the guide portion, and therefore when the upper body tilts. The movement trajectory can be made substantially constant.

  Further, the guide means is provided on both sides of the substrate as required. Thereby, since the guide means is provided on both sides of the substrate, the movement trajectory when the upper body tilts further can be made substantially constant, so that the wobbling of the upper body is reliably suppressed.

  Further, if necessary, the guided portion is constituted by a pin provided on the end side of the upper body, and the lower end of the guide portion is fixed to the side portion of the substrate and the upper body. It is comprised by the sheet-like member which was formed in the circular arc shape centering on the shaft center of this, and had the opening which the said pin penetrates. As a result, when the upper body tilts, the pin moves in an arc shape around the axis of the upper body along the opening formed in the sheet-like member as the guide portion. The body tilts about its axis. At this time, since the sheet-like member as the guide portion is fixed to the substrate, the upper body surely tilts with respect to the substrate along the longitudinal direction of the substrate about its axis, and therefore The moving trajectory when the upper body tilts can be made substantially constant, and the wobbling of the upper body is suppressed. Further, even if the upper body is swung to the left and right, the upper body is restrained by the sheet-like member, so that the situation where the upper body is unstable is suppressed, and the upper body is tilted smoothly.

  Furthermore, if necessary, the guided portion is constituted by a cable body, one end portion of the cable body is fixed to one end in the longitudinal direction of the upper body, and the other end portion is fixed to the longitudinal direction of the upper body. The intermediate portion is disposed along the side portion of the substrate, and the guide portion is provided with an insertion hole that is provided on the side portion of the substrate and through which the cable body is inserted. is doing. As a result, when the upper body tilts, the upper body moves either one of the longitudinal ends of the upper body or the other end of the longitudinal direction downward toward the substrate side, and the other of the upper body moves upward. While moving, the cord body also follows the tilting of the instep body. At this time, since the cord body moves along the insertion hole of the guide portion, the upper body surely tilts along the longitudinal direction of the substrate about its axis with respect to the substrate. The movement trajectory when the upper body tilts can be made substantially constant, and wobbling of the upper body is suppressed. Even if the upper body is swung to the left or right, the upper body is pulled by the cable body, so that the situation where the upper body is shaken is reliably suppressed, and the upper body is tilted smoothly.

  And as needed, the said guide part is comprised with the group of a pair of ring-shaped member provided on both sides of the edge part of the said upper body. As a result, since the guide portion can be configured with the minimum necessary members for forming the insertion hole, the member provided on the substrate can be compared with the case where the guide portion is configured with a cylindrical tube member. As much as possible, the comfort can be improved.

  Further, if necessary, the guided portion is configured by a cylindrical member provided on the end side of the upper body and formed in an arc shape, and the guide portion is movably inserted into the cylindrical member. And one end and the other end of the rope are fixed to the substrate with the end of the upper body interposed therebetween. Thereby, the cable body as the guide portion is inserted into the cylindrical member as the guided portion and formed in an arc shape, and when the upper body tilts, the cylindrical member moves along the cable body. Since it moves in the shape of an arc centering on the axis of the upper body, the upper body tilts about the axis. Therefore, the upper body surely tilts with respect to the substrate along the longitudinal direction of the substrate about its axis, so that the trajectory when the upper body tilts can be made substantially constant. The wobbling of the upper body is suppressed. Even if the upper body is swung to the left or right, the upper body is pulled by the cable body, so that the situation where the upper body is shaken is reliably suppressed, and the upper body is tilted smoothly.

  Furthermore, if necessary, a rising edge that rises from the end of the upper body is formed on an inclined surface that contacts the substrate at the tilting end. As a result, when the upper body is tilted, the rising edge abuts against the substrate, so that the support for the substrate is stable and it is easy to walk in use. In addition, the appearance when the upper body tilts appears to be almost the same as that of footwear such as general slippers and sandals.

  Furthermore, it is set as the structure which provided the biasing means which biases the said upper body to a neutral position as needed. As a result, when the two-way footwear is taken off, the upper body is returned to the neutral position by the biasing means, so that the upper body is always positioned at the neutral position when not in use. Since the space formed between the two can be increased, the foot can be easily inserted into the space when used, and the ease of wearing can be improved.

  Furthermore, if necessary, the upper body is made of an elastically deformable member, and its end is attached to the substrate so that it can be positioned in a neutral position when not in use. As a result, when the foot is inserted into the space formed between the substrate and the upper body, the upper body is pushed by the upper of the foot and the end is bent, and the upper body is tilted by the bending of the end. To do. Also, when the foot was pulled out of the space formed between the board and the upper body, the pressure on the upper part of the foot disappeared and the end part bent, and the upper part of the upper body was inserted by the bending of the end part Tilt to the side and return to the neutral position. Therefore, the upper body is tilted by bending of the end of the upper body during use, and when it is not used, it returns to the neutral position by its elastic force, so the space formed between the board and the upper body should be enlarged. This makes it easier to insert the foot into this space when used, further improving ease of wearing.

  Further, if necessary, the upper body is configured to be rotatably attached to a side portion of the substrate via a rotation shaft having an axis along the width direction. As a result, the upper body rotates and tilts about the rotation axis, so that the tilting can be performed more smoothly.

  According to the bidirectional footwear of the present invention, when one foot or the other side in the longitudinal direction of the substrate is inserted into a space formed between the substrate and the upper body and the foot is placed on the substrate. The instep body is pushed by the instep of the inserted foot and tilts with the width direction as the axis on the side opposite to the side through which the foot is inserted. At this time, the upper body is tilted while being guided by the guide means, and therefore, the situation where the upper body swings to the left and right is suppressed, and the upper body is tilted smoothly. That is, since the upper body is guided by the guide means regardless of which side of the substrate is worn from one side or the other side in the longitudinal direction, the ease of wearing is improved.

  In addition, when an urging means for urging the upper body to the neutral position is provided, the upper body is returned to the neutral position by the urging means when the bidirectional footwear is removed. Since the body is positioned at the neutral position, the space formed between the board and the upper body can be enlarged, so that it is easier to insert the foot into this space when using it, and more Ease of wearing can be further improved.

Hereinafter, an interactive footwear according to an embodiment of the present invention will be described with reference to the accompanying drawings.
1 to 8 show a bidirectional footwear S according to a first embodiment of the present invention. The basic configuration of the bidirectional footwear S includes a substrate 1, an upper body 10, and guide means 20.

  The substrate 1 includes a plate-like placement member 3 on which a foot is placed on the upper surface 2 and a grounding member 4 that is attached to the lower surface of the placement member 3 and contacts the floor surface. The grounding member 4 is formed in the same shape as the mounting member 3 in a plan view and a bottom view.

  The upper body 10 is in the middle of the longitudinal direction 5 of the substrate 1, spans the both sides 6 of the substrate 1, covers the instep when used, and the width direction 7 orthogonal to the longitudinal direction 5 of the substrate 1. Both end portions 11 are attached to the substrate 1 so as to be tiltable with respect to the axis. In the first embodiment, the upper body 10 is attached to both side portions 11 of the substrate 1 via the rotation shaft 12 having the axis along the width direction 7 on both sides 6 of the substrate 1. 12 is attached so as to be rotatable around the center. The rotating shaft 12 constitutes an urging means for urging the upper body 10 to the neutral position N, and is made of elastic rubber. The one end 12a is embedded and fixed in the substrate 1 and the other end The portion 12 b is fixed to the end portion 11 of the upper body 10. Further, the upper body 10 has a rising edge portion 13 rising from an end portion 11 formed on an inclined surface that abuts the substrate 1 at a tilting end 14.

  The guide means 20 guides the upper body 10 when the upper body 10 is tilted. The guided means 21 is provided on the upper body 10 and moves along with the upper body 10, and the guided part 21 is movable. And a guide portion 22 for guiding the head. The guide means 20 is provided on each side 6 of the substrate 1.

  In the first embodiment, the guided portion 21 is composed of a pin 30 provided on the end portion 11 side of the upper body 10, and is arranged at one longitudinal end 15 and the other longitudinal end 16 of the upper body 10. A pair is provided. The pin 30 includes a pin body 33 having a head portion 33a and a stopper 34 formed in the same shape as the head portion 33a and having a hole 34a through which the pin body 33 is inserted. When the upper body 10 comes into contact with the substrate 1 at the tilting end 14, a part thereof is provided so as to contact the upper surface 2 of the mounting member 3 of the substrate 1.

In the first embodiment, the guide portion 22 has an opening in which the lower end 23 is fixed to the side portion 6 of the substrate 1 and is formed in an arc shape centered on the axis of the upper body 10 and through which the pin 30 is inserted. The sheet-like member 25 having 24 is constituted. The sheet-like member 25 is formed in a semicircular shape, and the straight side is fixed to the side portion 6 of the substrate 1 as a lower end 23. The sheet-like member 25 is provided between the upper body 10 and the side portion 6 of the substrate 1, and is attached to the side portion 6 of the substrate 1 together with the upper body 10 by the rotating shaft 12. Further, the opening 24 formed in the sheet-like member 25 is such that the upper body 10 tilts so that a part of one pin 30 a of the pair of pins 30 contacts the upper surface 2 of the mounting member 3 of the substrate 1. When in contact with each other, the other pin 30b is locked so that the middle of the arc is cut.
The pin main body 33 is inserted into the opening 24 from the upper body 10 side, and the hole 34a of the stopper 34 is inserted into the pin main body 33 from the opposite side of the head 33a, so that the pin main body 33 is provided in the upper body 10. It has been.

  Therefore, when the bidirectional footwear S according to the first embodiment is used, the operation is as follows. In the bidirectional footwear S, the upper body 10 is normally located at the neutral position N.

  In a state where the upper body 10 is located at the neutral position N, the foot is inserted into the space formed between the substrate 1 and the upper body 10 from one side or the other side in the longitudinal direction 5 of the substrate 1. When the foot is placed on the substrate 1, as shown in FIG. 8, the upper body 10 is pushed by the instep of the inserted foot (the foot is not shown), and the side through which the foot is inserted It rotates and tilts about the rotation shaft 12 to the opposite side. At this time, since the rotating shaft 12 is formed of elastic rubber, the rubber is twisted. Further, the upper body 10 tilts while being guided by the guide means 20. Specifically, when the upper body 10 is pushed by the instep of the foot, the pin 30 provided on the upper body 10 is centered on the axis of the upper body 10 along the opening 24 formed in the sheet-like member 25. The upper body 10 tilts about its axis. Since the sheet-like member 25 as the guide portion 22 is fixed to the substrate 1, the upper body 10 surely tilts with respect to the substrate 1 along the longitudinal direction 5 of the substrate 1 around the axis. Therefore, the movement trajectory when the upper body 10 tilts can be made substantially constant, and the situation where the upper body 10 swings to the left and right is suppressed and is smoothly tilted. That is, since the upper body 10 is guided by the guide portion 22, the forward trajectory when the upper body 10 tilts from the neutral position N can be made substantially constant, and the ease of wearing is improved. Can do. In addition, even if the upper body 10 is swung to the left and right, the upper body 10 is restrained by the sheet-like member 25, so that the situation in which the upper body 10 is wobbled is also suppressed and can be smoothly tilted. .

  Further, when the user walks while wearing the bidirectional footwear S, the upper body 10 tilts around one axis and the other side of the board 1 around the axis center according to the movement of the upper of the foot. Since the rising edge 13 is formed on the inclined surface that contacts the substrate 1 at the tilting end 14, the rising edge 13 comes into contact with the substrate 1 when the upper body 10 is tilted. Support for 1 is stable, and it becomes easy to walk during use. Further, when the tilting end 14 comes into contact with the mounting member 3 of the substrate 1, the pin 30 also comes into contact with the mounting member 3 of the substrate 1, so that also in this respect, the support to the substrate 1 is stable and it is easy to walk during use. . Furthermore, the appearance of the bi-directional footwear S when used becomes substantially the same as that of footwear such as general slippers and sandals.

  When the foot is removed from the space formed between the substrate 1 and the upper body 10 to remove the bidirectional footwear S, there is no pressing force on the upper body 10 by the upper of the foot. The rotating shaft 12 that has been set is going to return to its original position. By the urging force of the rotating shaft 12, the upper body 10 rotates and tilts around the rotating shaft 12 toward the side where the foot is inserted, and returns to the neutral position N. At this time, the upper body 10 is tilted while being guided by the guide means 20, so that the upper body 10 is reliably tilted with respect to the substrate 1 along the longitudinal direction 5 about the axis. Therefore, the return path when the upper body 10 is tilted back to the neutral position N can be made substantially constant, so that the upper body 10 surely returns to the neutral position N. Since the situation where the upper body 10 swings from side to side and the like is suppressed, it can be smoothly tilted. In addition, even if the upper body 10 is swung to the left and right, the upper body 10 is restrained by the sheet-like member 25, so that the situation where the upper body 10 is wobbled is also suppressed, and the upper body 10 is smoothly tilted. Can do. In this case, when the bidirectional footwear S is removed, the upper body 10 is returned to the neutral position N by the urging means, so that the upper body 10 is always positioned at the neutral position N when not in use. Since the space formed between 1 and the upper body 10 can be enlarged, it becomes easy to insert the foot into this space during use, and the ease of wearing can be improved.

  That is, the upper body 10 is guided by the guide means 20 so that the forward path and the return path always have a constant path along the longitudinal direction 5 of the substrate 1. The upper body 10 surely returns to the neutral position N when it is taken off, and it is easy to wear it from either one side or the other side in the longitudinal direction 5 of the substrate 1 when it is next put on.

  9 to 12 show a bidirectional footwear S according to the second embodiment of the present invention. The basic configuration of the bidirectional footwear S includes a substrate 1, an upper body 10, and guide means 20.

  The substrate 1 includes a mounting member 3 and a grounding member 4 configured in the same manner as the bidirectional footwear S according to the first embodiment of the present invention. A cut portion 8 having a predetermined length is formed along the side portion 6 in the direction 5.

  In the second embodiment, the upper body 10 is formed of an elastically deformable member, and its end 11 is attached to the substrate 1 so that it can be positioned at the neutral position N when not in use. Specifically, both end portions 11 of the upper body 10 are embedded in the mounting member 3 from the cut portion 8 of the substrate 1, and are attached to the substrate 1 with an adhesive or the like in the mounting member 3. . Other configurations are the same as those of the first embodiment.

  As in the first embodiment of the present invention, the guide means 20 includes a guided portion 21 and a guide portion 22, and is provided on both side portions 6 of the substrate 1.

  In the second embodiment, the guided portion 21 is constituted by a cord body 31. The cable body 31 has one end 31a fixed to one end 15 in the longitudinal direction of the upper body 10, the other end 31b fixed to the other end 16 in the longitudinal direction of the upper body 10, and an intermediate part 31c serving as a substrate. 1 is disposed on the upper surface 2 of the mounting member 3 along the side portion 6 thereof.

  In the second embodiment, the guide portion 22 is formed of a pair of ring-shaped members 27 provided on the side portion 6 of the substrate 1 and having insertion holes 26 through which the ropes 31 are inserted. The pair of ring-shaped members 27 are fixed to the upper surface 2 of the mounting member 3 of the substrate 1 with the end portion 11 of the upper body 10 interposed therebetween.

  Therefore, when the bidirectional footwear S according to the second embodiment is used, the operation is as follows. The bidirectional footwear S is normally located at the neutral position N.

  In a state where the upper body 10 is located at the neutral position N, the foot is inserted into the space formed between the substrate 1 and the upper body 10 from one side or the other side in the longitudinal direction 5 of the substrate 1. When the foot is placed on the substrate 1, the upper body 10 is pushed by the inserted instep of the foot and the end portion 11 is bent, and the upper body 10 is inserted by the bending of the end portion 11. Tilts about the width direction 7 as an axis on the opposite side to the opposite side. At this time, the upper body 10 tilts while being guided by the guide means 20.

  Specifically, when the instep body 10 is pushed by the instep of the foot, the end portion 11 of the instep body 10 bends, and either the longitudinal one end 15 or the other longitudinal end 16 of the instep body 10 (the foot is The side opposite to the inserted side) moves downward toward the substrate 1 side, and the other (side where the foot is inserted) moves upward, and the rope 31 also tilts the upper body 10. Follow and move. At this time, the cord body 31 moves along the insertion hole 26 of the ring-shaped member 27, so that the upper body 10 reliably tilts along the longitudinal direction 5 of the substrate 1 with respect to the substrate 1 as the center. Therefore, the movement trajectory when the upper body 10 is tilted can be made substantially constant, and the situation where the upper body 10 swings to the left and right is suppressed and is smoothly tilted. That is, since the upper body 10 is guided by the guide portion 22, the forward trajectory when the upper body 10 tilts from the neutral position N can be made substantially constant, and the ease of wearing is improved. Can do. Further, even if the upper body 10 is swung to the left and right, the upper body 10 is pulled by the cable body 31, so that the situation where the upper body 10 is wobbled is reliably suppressed, and the upper body 10 is tilted smoothly.

  Then, when the user removes the foot from the space formed between the substrate 1 and the upper body 10 in order to remove the bidirectional footwear S, the pressure on the upper part of the foot disappears and the end portion 11 of the upper body 10 is removed. The upper body 10 tilts with the width direction 7 as an axis toward the side where the foot is inserted, and returns to the neutral position N. At this time, the upper body 10 is tilted while being guided by the guide means 20, so that the upper body 10 is reliably tilted with respect to the substrate 1 along the longitudinal direction 5 about the axis. Therefore, the return path when returning to the neutral position N from the position where the upper body 10 is tilted can be made substantially constant, so that the upper body 10 surely returns to the neutral position N. For this reason, the upper body 10 is tilted by the bending of the end 11 of the upper body 10 during use and returns to the neutral position N by its elastic force when not in use, so that it is formed between the substrate 1 and the upper body 10. The space can be increased, and the foot can be easily inserted into the space when used, and the ease of wearing can be further improved.

In the second embodiment, since the guide portion 22 is constituted by a pair of ring-shaped members 27, the guide portion 22 can be constituted by a minimum necessary member for forming the insertion hole 26. Compared to the case where the portion 22 is formed of a tubular tube member, the number of members provided on the substrate 1 can be reduced as much as possible, and thus the comfort can be improved. Furthermore, since the end portion 11 is embedded in the substrate 1, when the foot is placed on the substrate 1, the end portion 11 does not come into contact with the foot, and in this respect, the comfort can be improved.
Other actions and effects are the same as in the first embodiment.

FIGS. 13 to 16 show a bidirectional footwear S according to a third embodiment of the present invention. The basic configuration of the bidirectional footwear S includes a substrate 1, an upper body 10, and guide means 20.
The board | substrate 1 and the upper body 10 are comprised similarly to 2nd embodiment.

  As in the first and second embodiments of the present invention, the guide means 20 includes a guided portion 21 and a guide portion 22, and is provided on both side portions 6 of the substrate 1.

  In the third embodiment, the guided portion 21 includes a cylindrical member 32 that is provided on the end 11 side of the upper body 10 and is formed in an arc shape.

  In the third embodiment, the guide portion 22 is configured by a cord body 28 that is movably inserted into the cylindrical member 32. One end portion 28 a and the other end portion 28 b of the rope body 28 are fixed to the upper surface 2 of the mounting member 3 of the substrate 1 with the end portion 11 of the upper body 10 interposed therebetween.

  Therefore, when the bidirectional footwear S according to the third embodiment is used, the following effects are obtained. The bidirectional footwear S is normally located at the neutral position N. Further, the cable body 28 as the guide portion 22 is inserted into the cylindrical member 32 as the guided portion 21 and is formed in an arc shape.

  In a state where the upper body 10 is located at the neutral position N, the foot is inserted into the space formed between the substrate 1 and the upper body 10 from one side or the other side in the longitudinal direction 5 of the substrate 1. When the foot is placed on the substrate 1, the upper body 10 is pushed by the inserted instep of the foot and the end portion 11 is bent, and the upper body 10 is inserted by the bending of the end portion 11. Tilts about the width direction 7 as an axis on the opposite side to the opposite side. At this time, the upper body 10 tilts while being guided by the guide means 20.

  Specifically, when the instep body 10 is pushed by the instep of the foot, the end 11 of the instep body 10 is bent, and the cylindrical member 32 is a circle centering on the axis of the instep body 10 along the cord body 28. By moving in an arc shape, the upper body 10 tilts to the side opposite to the side where the foot is inserted with its axis as the center. Since the cable body 28 is fixed to the upper surface 2 of the mounting member 3 of the substrate 1, the cylindrical member 32 can be reliably moved in an arc shape. For this reason, the upper body 10 reliably tilts along the longitudinal direction 5 of the substrate 1 with respect to the substrate 1 as the center, so that the movement trajectory when the upper body 10 tilts is substantially constant. The situation where the upper body 10 swings from side to side and the like is prevented from being wobbled, and can be tilted smoothly. That is, since the upper body 10 is guided by the guide portion 22, the forward trajectory when the upper body 10 tilts from the neutral position N can be made substantially constant, and the ease of wearing is improved. Can do. Further, even if the upper body 10 is swung to the left and right, the upper body 10 is pulled by the cord body 28, so that the situation where the upper body 10 is wobbled is reliably suppressed, and can be tilted smoothly.

Then, when the user removes the foot from the space formed between the substrate 1 and the upper body 10 in order to remove the bidirectional footwear S, the pressure on the upper part of the foot disappears and the end portion 11 of the upper body 10 is removed. The upper body 10 tilts with the width direction 7 as an axis toward the side where the foot is inserted, and returns to the neutral position N. At this time, the upper body 10 is tilted while being guided by the guide means 20, so that the upper body 10 is reliably tilted with respect to the substrate 1 along the longitudinal direction 5 about the axis. Therefore, the return path when returning to the neutral position N from the position where the upper body 10 is tilted can always be constant, so that the upper body 10 surely returns to the neutral position N.
