  However, according to the technique of Patent Document 1, the locking buckle is not fixed when the occupant is not restrained by the seat belt, that is, when it is not used. For this reason, there is a possibility that the locking buckle will hit the vehicle due to the shaking of the vehicle, etc., causing noise and damage to the interior parts.

  Therefore, an object of the present invention is to prevent the occurrence of noise and damage to interior parts due to the buckle hitting the vehicle even when the passenger is not restrained by the seat belt.

  In order to achieve the above object, the present invention provides a connecting portion to which a tongue is connected when a seat belt is used, a belt-like portion having one end connected to the connecting portion, and a fixing connected to the other end of the belt-like portion. An insertion portion that is inserted through the fixing portion, the insertion portion that fixes the fixing portion to the vehicle body, and the insertion portion is inserted, and is disposed closer to the vehicle body than the fixing portion, and the seat belt It is characterized by comprising a holding part for holding the connecting part when not used.

  According to such a configuration, the connecting part is connected to the fixed part fixed to the vehicle body by the insertion part via the belt-like part, and is located near the vehicle interior part (eg, interior panel, ornament). doing. If the seat belt is not used, the connecting portion is held by the holding portion, so that the connecting portion does not hit the vehicle even if the vehicle shakes. Therefore, it is possible to prevent the occurrence of noise and damage to the interior parts due to the connection portion hitting the vehicle.

  Moreover, it is good to provide the removal prevention part which the said insertion part has penetrated and is arrange | positioned in the vehicle body side rather than the said holding | maintenance part, and prevents the said holding | maintenance part falling out of the said insertion part.

  According to such a configuration, it is possible to prevent the holding portion from being detached from the insertion portion when performing an operation of fixing the fixing portion to the vehicle body using the insertion portion. For example, in the insertion direction of the insertion part, if the removal prevention part partially covers the holding part from the vehicle body side, the holding part does not come off from the insertion part.

  The insertion portion is inserted, is disposed between the fixing portion and the holding portion, and conceals a predetermined region including a portion where the insertion portion is fixed to the vehicle body from the vehicle compartment side. A concealing unit may be provided.

  According to such a configuration, even if the user of the vehicle sees the portion where the insertion portion is fixed to the vehicle body from the passenger compartment side, the user can mainly see only the concealment portion. Therefore, it is possible to prevent the inside of the vehicle body that is closer to the vehicle body than the concealing portion from being seen.

  The insertion portion is inserted, and is provided between the concealing portion and the removal prevention portion, and further includes a pinching prevention portion provided in an insertion hole of the holding portion through which the insertion portion is inserted. In the insertion direction of the insertion portion, the pinching prevention portion may be thicker than the holding portion.

  According to such a configuration, since a considerable amount of gap is formed between the concealing portion and the removal preventing portion by the pinching prevention portion, it is possible to prevent the holding portion from being pinched. Thereby, the torque reduction of the torque which arises when an insertion part fixes a fixing | fixed part to a vehicle body can be prevented, and a fixing | fixed part can be favorably fixed to a vehicle body by an insertion part.

  According to the present invention, even when the occupant is not restrained by the seat belt, it is possible to prevent generation of noise and damage to interior parts due to the buckle hitting the vehicle.

The upper surface portion formed on the second shaft portion 1a2 is flush with the upper surface portion of the upper flange portion 10a of the bearing 10.
The flange portion 1c is located between the second shaft portion 1a2 and the head portion 1b and has a disk shape. The upper surface of the flange portion 1 c is in contact with the lower surface of the lower flange portion 10 b of the bearing 10. The diameter of the flange portion 1 c is the same as the outer diameter of the lower flange portion 10 b of the bearing 10.

(Washer 2)
The washer 2 has a convex portion formed by cutting out at an equal interval so that the inner peripheral side is screwed with the bolt 1. The washer 2 is disposed on the upper surface of the first collar 3, that is, on the vehicle body side of the first collar 3, and the bolt 1 is inserted therethrough. Further, when the position setting unit M is attached to the vehicle body panel R, the washer 2 is in contact with the lower end of the female screw R1. That is, when attaching the position setting unit M, the bolt 1 is tightened until the washer 2 contacts the lower end of the female screw R1. Since the washer 2 is screwed with the bolt 1, if a predetermined condition is satisfied, the component through which the bolt 1 is inserted can be pressed from above. Therefore, the washer 2 can prevent the components inserted through the bolt 1, in particular, the belt 4 from coming off the bolt 1. The washer 2 is made of metal, for example.

The first collar 3 has a cylindrical shape having an axis in the vertical direction. The first collar 3 is disposed above the belt 4 and the bolt 1 is inserted therethrough. The outer diameter of the first collar 3 is larger than the outer diameter of the washer 2. The first collar 3 determines the position of the washer 2 in the axial direction (vertical direction) of the bolt 1 at a predetermined position, so that when the position setting unit M is attached, the first wall 6b of the rotation preventing unit 6 is Contact with the panel R can be prevented. Further, the first collar 3 has a thickness in the vertical direction that can prevent the oval plate 5 from coming into contact with the interior panel I when the position setting portion M is attached (see, for example, FIG. 4). ). The first collar 3 is made of metal, for example.

(Belt 4)
The belt 4 has a belt shape and is provided with a fastener that can be attached and detached on a surface. The belt 4 of the present embodiment is made of, for example, resin, and a hooked region (hook) is formed only on the upper surface side of one end region, and only on the lower surface side of the other end region, A region (loop) raised densely in a loop shape is formed (see FIG. 5). It can be attached simply by pressing the hook and loop, and then can be peeled off or attached again. The belt 4 is disposed on the upper surface of the oval plate 5, that is, on the vehicle body side of the oval plate 5, and has a circular columnar insertion hole 4a through which the bolt 1 is inserted (see FIG. 5). ).

  In the present embodiment, the outer diameter of the first collar 3 used for the position setting unit M is larger than the diameter of the insertion hole 4 a of the belt 4. Then, the first collar 3 partially covers the belt 4 from the vehicle body side (from above). Therefore, the belt 4 can be prevented from coming off from the bolt 1 when the position setting unit M is attached during the operation of fixing the fixing plate 11 to the vehicle body using the bolt 1. Further, when the outer diameter of the first collar 3 is made larger than the diameter of the insertion hole 4 a of the belt 4, the outer diameter of the washer 2 may be made smaller than the diameter of the insertion hole 4 a. Even with the washer 2 having such a small diameter, the first collar 3 can be pressed from above, and the belt 4 does not come off.

On the other hand, a configuration in which the first color 3 is not used in the position setting unit M may be realized. In this case, it is necessary to make the outer diameter of the washer 2 larger than the diameter of the insertion hole 4 a of the belt 4. If designed in this way, the washer 2 partially covers the belt 4 from the vehicle body side (from above). Therefore, it is possible to prevent the belt 4 from coming off the bolt 1 by the washer 2 when the position setting unit M is attached.
In the present embodiment, the first collar 3 is used, and the washer 2 having an outer diameter larger than the diameter of the insertion hole 4a of the belt 4 is used.

(Oval plate 5)
The oval plate 5 has an oval plate shape extending in the horizontal direction. The oval plate 5 has insertion holes 5a and 5b (see FIG. 5 and the like) through which the bolt 1 and the first wall portion 6b of the rotation preventing portion 6 are inserted. The oval plate 5 is made of metal, for example. Details regarding the oval plate 5 will be described later.

  As shown in FIG. 5, the oval plate 5 includes an insertion hole 5 a through which the bolt 1 is inserted and an insertion hole 5 b through which the first wall portion 6 b of the rotation prevention unit 6 is inserted. The insertion hole 5a has a circular shape, and the insertion hole 5b has a rectangular shape. As shown in the bottom view of FIG. 6, the oval plate 5 has a size that can cover the hole Ia formed in the interior panel I from the passenger compartment side in order to attach the position setting portion M to the vehicle body panel R. ing. Therefore, even if the user of the vehicle V sees the position setting portion M attached to the vehicle body panel R from the passenger compartment side, the position setting unit M exists on the vehicle body side from the hole Ia formed in the interior panel I by the oval plate 5. The female screw R1 and the pin R2 of the body panel R to be hidden are concealed. Therefore, a predetermined region including a place where the bolt 1 is fixed to the vehicle body (specifically, for example, a region visible from the hole Ia formed in the interior panel I when the position setting unit M is not attached). By concealing from the passenger compartment side, it is possible to prevent the inside of the vehicle body on the vehicle body side from being seen from the oval plate 5.

(Rotation prevention part 6)
The rotation prevention unit 6 prevents the entire position setting unit M, each component of the position setting unit M, the link belt B, and the buckle S3 from rotating around the axis of the bolt 1. The rotation preventing unit 6 is made of metal, for example. Even if the belt 4 is to be rotated around the axis of the bolt 1, the belt 4 contacts the first wall 6 b of the rotation prevention unit 6. Therefore, the first wall 6 b can prevent the belt 4 from rotating around the axis of the bolt 1.

  As shown in FIGS. 5 and 7, the rotation prevention unit 6 includes a flat plate portion 6 a, the first wall portion 6 b described above, and a pair of front and rear second wall portions 6 c.

  The flat plate portion 6a has a tongue-shaped plate shape extending in the right direction. The flat plate portion 6a includes an insertion hole 6a1 through which the bolt 1 is inserted. When the first wall portion 6b is inserted through the insertion hole 5b of the oval plate 5 from the lower side (see, for example, FIG. 7C), the oval plate 5 is disposed on the upper surface of the flat plate portion 6a, that is, on the vehicle body side. Is done. Further, as shown in FIG. 4, the flat plate portion 6 a is disposed on the upper surface of the third collar 9, that is, on the vehicle body side.

  The first wall portion 6b has a tongue-shaped plate shape standing upward from the left end of the flat plate portion 6a. And the front-end | tip part of the 1st wall part 6b is extended to the left by forming the front-end | tip part of the 1st wall part 6b, for example, and forms the surface of a horizontal direction. The first wall 6b is formed with an insertion hole 6b1 extending from the center of the left end of the flat plate 6a to a part of the tip. The insertion hole 6b1 is a hole through which a columnar pin R2 that is fixed by welding, for example, is suspended from the vehicle body panel R when the position setting unit M is attached to the vehicle body panel R (FIG. 4). reference). By forming the insertion hole 6b1, the first wall portion 6b has a substantially inverted U shape when viewed from the right.

  As already described, the first wall portion 6b can prevent the belt 4 from rotating around the axis of the bolt 1. Further, the pin R2 inserted through the insertion hole 6b1 is locked with the first wall portion 6b when rotated around the axis of the bolt 1, so that the first wall portion 6b is prevented from rotating around the axis of the bolt 1. can do.

One of the pair of front and rear second wall portions 6c is a rectangular piece that extends forward from the front end of the flat plate portion 6a and further extends downward. The other of the second wall portions 6c is a rectangular piece extending rearward from the rear end of the flat plate portion 6a and further extending downward. Therefore, the second wall portions 6c and 6c have a substantially inverted L shape when viewed from the right. As shown in FIG. 7B, the second wall portions 6 c and 6 c extend to the front and rear outside of the fixed plate 11. Furthermore, as shown in FIG.7 (c), the lower end of 2nd wall part 6c, 6c is extended even below the lower surface extended in the horizontal direction of the fixed plate 11. As shown in FIG. Therefore, when the fixing plate 11 rotates around the axis of the bolt 1, the fixing plate 11 is locked with the second wall portions 6 c and 6 c, and thus the second wall portions 6 c and 6 c can be prevented from rotating around the axis of the bolt 1. it can.
As a result, the anti-rotation part 6 including the first wall part 6b and the second wall parts 6c and 6c has the entire connection part holding structure including the position setting part M with respect to the vehicle body panel R as the axis of the bolt 1. Rotating around can be prevented.

(Cover 7)
The cover 7 constitutes the appearance of the position setting unit M that can be seen by the user of the vehicle V. The cover 7 is opened at a portion to be engaged with the link belt B. The cover 7 can protect a part of the components of the position setting unit M and hide it from the user. The cover 7 is made of, for example, resin, and may be composed of two parts so that they can be fitted to each other. For example, after attaching the position setting unit M before use to the vehicle body panel R, the two parts constituting the cover 7 may be fitted at a position where some of the components of the position setting unit M can be protected.

(Second color 8)
The second collar 8 has a cylindrical shape having an axis in the vertical direction. The second collar 8 is disposed between the first collar 3 and the oval plate 5, and the bolt 1 is inserted therethrough. That is, the first collar 3 is disposed on the upper surface of the second collar 8, and the second collar 8 is disposed on the upper surface of the oval plate 5, that is, closer to the vehicle body side than the oval plate 5. Yes. Further, the outer diameter of the second collar 8 is smaller than the diameter of the insertion hole 4 a of the belt 4. Therefore, the second collar 8 is inserted through the insertion hole 4 a of the belt 4. Furthermore, the thickness of the second collar 8 is greater than the thickness of the belt 4 in the vertical direction. Therefore, when the second collar 8 is inserted through the insertion hole 4 a of the belt 4, a considerable gap G is formed between the first collar 3 and the oval plate 5.

  Therefore, it is possible to prevent the belt 4 from being caught by the first collar 3 and the oval plate 5. Thereby, the torque reduction of the torque which arises when the volt | bolt 1 fixes the fixing plate 11 to a vehicle body can be prevented, and the fixing plate 11 can be favorably fixed to the vehicle body by the volt | bolt 1. If the belt 4 having a low rigidity such as resin is sandwiched between the bolts 1, the torque generated by the tightening of the bolts 1 is reduced. As a result, there is a high possibility that the bolt 1 will come off the female screw R2. Therefore, the second collar 8 having high rigidity is used to avoid pinching the belt 4. The second collar 8 is made of metal, for example.

  When the first collar 3 is not used, a considerable amount of gap is formed between the washer 2 and the oval plate 5 by the second collar 8. Therefore, it is possible to prevent the belt 4 from being caught by the washer 2 and the oval plate 5.

(Third color 9)
The third collar 9 has a cylindrical shape having an axis in the vertical direction. As shown in FIG. 4, the third collar 9 is disposed on the upper surface of the upper flange portion 10a of the bearing 10 and on the upper surface of the second shaft portion 1a2 of the bolt 1, that is, on the vehicle body side. It is inserted. The thickness of the third collar 9 in the axial direction of the bolt 1 is, for example, a thickness that can prevent contact between the upper portion of the cover 7 and the rotation preventing portion 6, particularly contact with the flat plate portion 6 a. Therefore, the lower part of the third collar 9 is inside the cover 7. The third collar 9 is made of metal, for example.

(Bearing 10)
The bearing 10 has a cylindrical shape having an axis in the vertical direction (see FIG. 5 and the like). An upper flange portion 10 a extends in the horizontal direction at the upper end of the bearing 10. At the lower end of the bearing 10, a lower flange portion 10b extends in the horizontal direction. The bearing 10 having such a shape is fitted on the fixed plate 11. The bearing 10 is inside the cover 7. The bearing 10 is made of metal, for example.

(Fixing plate 11)
As shown in FIG. 4, the fixed plate 11 is a rectangular flat plate extending in the horizontal direction, and has a shape in which the flat plate is bent so as to substantially follow the shape of the upper portion of the cover 7. The fixing plate 11 is formed with an insertion hole 11 a through which the bolt 1 is inserted and fitted into the bearing 10. The link belt B is locked to the left end of the fixed plate 11. The fixing plate 11 is made of metal, for example.

≪Operation example≫
Here, an operation example of the present embodiment relating to the use of the seat belt will be described.
As shown in FIG. 2, the tongue S11 is connected to the buckle S3 when the seat belt is used. At this time, the hook and loop of the belt 4 are not bonded to each other. Therefore, the belt 4 does not hold the buckle S3.

  On the other hand, as shown in FIG. 3, when the seat belt is not used, the buckle S3 is not connected to the tongue S11. Therefore, the user of the vehicle V can take the buckle S3, fold the link belt B, and move the buckle S3 to below the position setting unit M. The user moves the buckle S3 to the lower side of the position setting unit M, picks up one end of the belt 4, passes the lower side of the buckle S3, and includes the buckle S3, the link belt B, and the position setting unit M. The belt 4 is wound around the entire connecting portion holding structure. After winding, the user attaches the hook and loop of the belt 4 together. Thereby, the belt 4 can hold | maintain the buckle S3. Therefore, for example, even if the vehicle V shakes during traveling, it is possible to prevent the occurrence of noise and damage to interior parts (eg, interior panels, decorative items) caused by the buckle S3 hitting the vehicle V.

With reference to FIG. 8, the operation example of this embodiment regarding attaching the position setting part M to the vehicle body panel R is demonstrated.
FIG. 8 is a rear view cross-sectional view of the position setting portion before attachment. 8 is the same as FIG. 4 and is a cut surface taken along the line AA shown in FIG.

  The link belt B is connected to the position setting unit M before being attached to the vehicle body panel R, and the buckle S3 is connected to the link belt B. In the position setting unit M, the washer 2, the first collar 3, the belt 4, the oval plate 5, the rotation prevention unit 6, the second collar 8, the third collar 9, the bearing 10, and the fixed plate 11, the bolt 1 is inserted. The washer 2 presses the first collar 3 from above, thereby fixing these components of the position setting unit M. However, the position setting unit M does not include the cover 7 before installation (for convenience of illustration, the cover 7 is indicated by a two-dot chain line), and the head 1b of the bolt 1 and the fixing plate 11 are exposed. It is in a state. The belt 4 is in a state where the hook and the loop are peeled off.

  The contractor of the vehicle V picks up the position setting part M in such a state, passes the hole formed in the interior panel I, and moves it to the front of the female screw R1 of the vehicle body panel R above the interior panel I. . Then, the trader uses a tool such as a spanner to screw the bolt 1 of the position setting unit M into the female screw R1. At that time, the contractor inserts the pin R2 of the vehicle body panel R into the insertion hole 6b1 of the first wall portion 6b of the rotation prevention unit 6. When the supplier further screwes the bolt 1 into the female screw R1, the washer 2 comes into contact with the lower end of the female screw R1. With this contact, the screwing of the bolt 1 and the female screw R1 can be completed.

  Thereafter, the trader picks up the cover 7 composed of the two parts and fits the two parts so as to cover the head 1b of the bolt 1, the fixing plate 11, and the like. With this fitting, the attachment of the position setting portion M to the vehicle body panel R can be completed. The state after the position setting unit M is attached is equal to that shown in FIG.

  During the operation of attaching the position setting unit M, the first collar 3 prevents the belt 4 from coming off from the bolt 1.

≪Summary≫
According to the present embodiment, even when the occupant is not restrained by the seat belt, it is possible to prevent generation of noise and damage to interior parts due to the buckle S3 hitting the vehicle V. The buckle S3 is connected to the fixing plate 11 fixed to the vehicle body by the bolt 1 via a belt-like portion, and is located near the interior parts (eg, interior panel, ornament) of the vehicle V. This is because when the seat belt is not used, the buckle S3 is held by the belt 4, so that the buckle S3 does not hit the vehicle V even if the vehicle V shakes.

  Moreover, when performing the operation | work which fixes the fixing plate 11 to a vehicle body using the volt | bolt 1, it can prevent that the belt 4 comes off from an insertion part. For example, in the axial direction of the bolt 1, the first collar 3 that does not come off the bolt 1 by the washer 2 partially covers the belt 4 from the vehicle body side. Therefore, the belt 4 does not come out of the bolt 1 when the fixing plate 11 is fixed to the vehicle body using the bolt 1.

  Further, even if the user of the vehicle V sees the part where the bolt 1 is fixed to the vehicle body (the position where the female screw R1 of the vehicle body panel R is located) from the passenger compartment side, the user is mainly obligated. Only plate 5 is visible. Therefore, it is possible to prevent the inside of the vehicle body that is closer to the vehicle body than the oval plate 5 from being seen.

  In addition, since a considerable amount of gap is formed between the oval plate 5 and the first collar 3 by the second collar 8, it is possible to prevent the belt 4 from being caught. Thereby, the torque reduction of the torque which arises when the volt | bolt 1 fixes the fixing plate 11 to a vehicle body can be prevented, and the fixing plate 1 can be favorably fixed to the vehicle body by the volt | bolt 1.

≪Others≫
The above embodiment is suitable for carrying out the present invention, but the form of implementation is not limited to this. Therefore, various modifications can be made to the implementation form without departing from the gist of the present invention.

First, a modified example of the connecting portion holding structure will be described.
FIG. 9A is a perspective view of a connecting portion holding structure according to a modified example, and FIG. 9B is a right side view of the connecting portion holding structure according to the modified example. FIG. 9 particularly shows the state when the seat belt is not used. The connecting portion holding structure in FIG. 9 is different from the connecting portion holding structure in FIG. 3 in that a grip portion 12 (holding portion) is used instead of the belt 4.

  The grip portion 12 includes an upper plate 12a, arm plates 12b and 12b, and hinges 12c and 12c. The grip part 12 is made of metal, for example.

  The upper plate 12a is a substantially rectangular flat plate whose longitudinal direction is the front-rear direction. The upper plate 12a is disposed on the upper surface of the oval plate 5, that is, on the vehicle body side, and has a circular insertion hole (not shown) through which the bolt 1 is inserted. The front end and the rear end of the upper plate 12a are bent so as to engage with the hinges 12c and 12c.

  The arm plates 12b and 12b are bending plates that are located on the outer side in the front-rear direction with respect to the position setting unit M, extend downward from the upper plate 12a, and further extend inward in the front-rear direction. The arm plates 12b and 12b have a substantially L shape when viewed in the left-right direction. The upper ends of the arm plates 12b and 12b are bent so as to engage with the hinges 12c and 12c.

  The hinges 12c and 12c are cylindrical bars extending in the left-right direction. The hinges 12c and 12c allow the arm plates 12b and 12b to move to the outside in the front-rear direction with respect to the upper side plate 12a so as to be rotatable in the front-rear direction.

The grip portion 12 includes a spring (not shown) that connects the upper plate 12a and the arm plates 12b and 12b. The spring generates an urging force by rotating the arm plates 12b and 12b, and returns the arm plates 12b and 12b to a predetermined position. The fixed position is a position where the arm plates 12b, 12b extend downward from the upper plate 12a, and is a position that is in the state shown in FIG.
Further, even when the gripping portion 12 tries to rotate around the axis of the bolt 1, it comes into contact with the first wall portion 6 b of the rotation prevention portion 6. Therefore, the first wall portion 6b can prevent the grip portion 12 from rotating around the axis of the bolt 1.

Next, an operation example of the connecting portion holding structure of this modification will be described.
When the seat belt is not used, the user of the vehicle V picks up the buckle S3 released from the tongue S11, folds the link belt B, and moves the buckle S3 to below the position setting unit M. Subsequently, the user picks up one of the arm plates 12b and 12b, moves it to the outside in the front-rear direction, expands the gripping portion 12, and stores the buckle S3 in the gripping portion 12. After the storage, when the user releases the arm plate 12b, the arm plate 12b returns to a fixed position by the biasing force of the spring. The lower portions of the arm plates 12b and 12b can support the buckle S3 from below (see FIG. 9B). Thereby, the holding part 12 can hold | maintain the buckle S3. Therefore, for example, even if the vehicle V shakes during traveling, it is possible to prevent the occurrence of noise and damage to the interior parts due to the buckle S3 hitting the vehicle V.

  In the present embodiment, the position setting unit M is attached to the vehicle body panel R constituting the roof of the vehicle V from the lower side to the upper side. That is, the axial direction of the bolt 1 of the position setting unit M is the same as the vertical direction (for example, see FIG. 4). However, the position setting unit M may be attached to a panel constituting the side of the vehicle V, for example. Therefore, the axial direction (insertion direction) of the bolt 1 of the position setting unit M is not limited to the vertical direction, and may be a horizontal direction or a diagonally upward / downward direction, which is referred to as a direction from the passenger compartment side to the vehicle side. be able to.

  In the present embodiment, the position setting unit M is fixed by the bolt 1 being screwed into the female screw R1 of the vehicle body panel R. However, for example, a cylindrical pin may be used in place of the bolt 1 and a pin receiving portion fitted to the tip of the pin may be fixed to the vehicle body panel R. Thereby, for example, if the contractor of the vehicle V fits the pin receiving portion with a pin inserted through a component of the position setting portion M, the position setting portion M can be fixed.

  In the present embodiment, a gap for the belt 4 is formed by the second collar 8 that fits in the insertion hole 4a of the belt 4 (see, for example, FIG. 4). However, instead of the second collar 8, an external fitting member that has an insertion hole through which the bolt 1 is inserted and that has a shape that is externally fitted to the belt 4 may be used. The outer fitting member is made of metal, for example, and has a correspondingly large rigidity. The vehicle body side surface (upper surface) of the outer fitting member is in contact with the vehicle interior side surface (lower surface) of the first collar 3. Further, the surface of the outer fitting member on the vehicle compartment side is in contact with the surface of the oval plate 5 on the vehicle body side. The inside of the outer fitting member forms a gap for the belt 4. Therefore, it is possible to prevent the belt 4 from being caught by the first collar 3 and the oval plate 5.

  Further, the grip portion 12 of the position setting portion M described as a modification of the connecting portion holding structure (see FIG. 9) may be made of resin. And you may integrally mold the resin-made holding parts 12 so that it may become the same shape as what was shown in FIG. By making the gripping part 12 made of resin, the elasticity of the gripping part 12 itself can be increased, and a spring (not shown in FIG. 9) used for the metal gripping part 12 can be made unnecessary.

  Further, in the position setting unit M described as a modified example of the connecting portion holding structure (see FIG. 9), the gripping portion 12 extends in the circumferential direction of the bolt 1 so as to surround the position setting unit M from front, rear, left and right. May be provided. For example, the circumferential plate extends in the left-right direction from a part of the left and right ends of the plate-like portion extending in the up-down direction of the arm plates 12b, 12b, and further has four L-shapes extending inward in the front-rear direction. It is good to comprise as a board. If the gripping portion 12 includes a circumferential plate, for example, a situation in which the buckle S3 moves from the gripping portion 12 to the left side or the right side and falls due to the shaking of the vehicle V can be avoided.

A technique in which technical matters described in this embodiment are appropriately combined can also be realized.
In addition, specific configurations such as shapes, materials, and arrangements of various members necessary for the present invention can be appropriately changed without departing from the spirit of the present invention.
