Description

Technical Field

[0001] The present invention relates to a buckle mounted on a stud bolt or the like. Background Art

[0002] Conventionally, for example, when installing an insulator or the like on the floor of an automobile, or when installing a bushing or the like inside a wheel well, a fastening structure composed of a stud bolt and a nut is used. For example, a stud bolt is provided on the body of an automobile, and when an installation member such as an insulator or a bushing is passed through by the stud bolt, it is fastened with a nut. For example, in the invention described in Patent Document 1 below (hereinafter referred to as "Document-Public-Known Invention 1"), a plastic buckle is used instead of a nut.

[0003] The buckle of Document-Public-Known Invention 1 has a cylindrical body with a hole through which a stud bolt passes. By cutting off a part of the side surface of the cylindrical body, a flexible arm is formed on a part of the side surface. A thread groove that engages with the stud bolt is formed on the inner surface of the flexible arm. A swing piece is connected to the upper end of the cylindrical body, and the swing piece swings with the connection part as a starting point. The swing piece is split into two and a groove is formed therebetween. When the cylindrical body is clamped by the groove, the flexible arm is clamped from the outside by the swing piece. The clamped flexible arm bends inward, engages with the stud bolt passing through the cylindrical body, and is pressed, so that the buckle is mounted on the stud bolt.

[0007] Problems to be Solved by the Invention

[0008] However, in Document-Public-Known Invention 1, the thread groove formed on the inner surface of the flexible arm is not necessarily the same size as the thread groove of the stud bolt, and sometimes the pitch of the thread groove of the stud bolt is not suitable either. In this case, the buckle is mounted on the stud bolt with a gap between the buckle and the installation member, so the installation member shakes at the gap. Therefore, it is sometimes necessary to re-fasten the buckle.

[0009] The present invention has been made in view of such actual circumstances. An object of the present invention is to provide a buckle that can fix an installation member without shaking on an installation surface. In addition, in a broad sense, an object of the present invention is to suppress the emission of harmful substances and improve a comfortable environment as a general issue.

[0010] Means for Solving the Problems

[0011] To achieve the above object, the buckle of the present invention is mounted on the mounting bolt to fix the mounted member through which the mounting bolt fixed to the mounting surface is passed to the mounting surface. The buckle is characterized in that it has: a main body portion formed with an insertion path through which the mounting bolt passes; a claw portion disposed on the insertion path and engaging with the mounting bolt; a fixing portion mounted on the main body portion; the buckle is deformed into a separated posture or a fixed posture, the separated posture being a posture in which the fixing portion is separated from the mounted member, and the fixed posture being a posture in which the fixing portion is pressed against the mounted member and presses the main body portion in a direction away from the mounted member.

[0012] The buckle of the present invention is characterized in that the pressing end portion of the fixing portion that abuts against the mounted member in the fixed posture protrudes toward the mounted member compared to the main body end portion of the main body portion that abuts against or approaches the mounted member in the separated posture.

[0013] The buckle of the present invention is characterized in that the main body portion and the fixing portion are pre-connected by a rotating shaft portion.

[0014] The buckle of the present invention is characterized in that the main body portion and the fixing portion are connected by a track structure, and the fixing portion moves along the track structure.

[0015] The buckle of the present invention is characterized in that the main body portion and the fixing portion are fitted together in the fixed posture.

[0016] The buckle of the present invention is characterized in that it has the following outer shape: by contacting a restricting portion formed around the mounting bolt, rotation about the mounting bolt is restricted.

[0017] The buckle of the present invention is characterized in that the main body portion has: a side surface portion formed with the insertion path; a main body end portion formed at an end on the entrance side of the insertion path; the side surface portion has: the claw portion formed on the inner surface of the side surface portion; a rotating shaft portion formed on the outer surface of the side surface portion; a track groove portion formed on the outer surface of the side surface portion and around the rotating shaft portion; a fitting protrusion portion formed on the outer surface of the side surface portion and around the rotating shaft portion; the fixing portion has: an arm portion supported on the rotating shaft portion and opposite to the outer surface of the side surface portion; a rod portion connected to the arm portion and protruding compared to the main body portion; the arm portion has: the pressing end portion formed at the edge of the arm portion; a track protrusion portion formed on the inner surface of the arm portion and along the track groove portion; a fitting hole portion formed on the inner surface of the arm portion and fitted with the fitting protrusion portion.

[0018] Effects of the Invention

[0019] The buckle of the present invention is mounted on a mounting bolt to fix a mounted member through which the mounting bolt fixed to a mounting surface is passed to the mounting surface. The buckle has: a main body portion formed with an insertion path through which the mounting bolt passes; a claw portion disposed on the insertion path and engaging with the mounting bolt; and a fixing portion mounted on the main body portion. The buckle is deformed into a separated posture or a fixed posture. The separated posture is a posture in which the fixing portion is separated from the mounted member, and the fixed posture is a posture in which the fixing portion is pressed against the mounted member and the main body portion is pressed in a direction away from the mounted member. In the separated posture, when the mounting bolt passes through the insertion path of the main body portion, the claw portion engages with the mounting bolt. In a state where the claw portion engages with the mounting bolt, when deformed into the fixed posture, the fixing portion is pressed against the mounted member, and the main body portion is pressed in a direction away from the mounted member through the fixing portion. Therefore, in the separated posture, even if it is assumed that the pitch of the thread groove of the claw portion does not match the pitch of the mounting bolt, or there is a gap between the main body portion and the mounted member, since the fixing portion presses in a direction to separate the two between the mounted member and the main body portion, the claw portion is engaged in a state where it matches the pitch of the thread groove. Thus, the mounted member can be fixed to the mounting surface without shaking.

[0020] In the buckle of the present invention, a pressing end portion of the fixing portion that abuts against the mounted member in the fixed posture protrudes toward the mounted member compared to a main body end portion of the main body portion that abuts against or approaches the mounted member in the separated posture. With this configuration, in the separated posture, the main body end portion abuts against (or approaches) the mounted member, and when deformed into the fixed posture, the pressing end portion abuts against the mounted member. That is, the degree of protrusion with respect to the mounted member (hereinafter referred to as "protrusion amount"). The pressing end portion is more than the main body end portion. Therefore, in the fixed posture, when the pressing end portion is pressed against the mounted member, the main body end portion is separated from the mounted member by an amount corresponding to the difference in the protrusion amount, and the main body portion is pressed in a direction away from the mounted member. Thus, the mounted member can be fixed to the mounting surface without shaking.

[0021] In the buckle of the present invention, the main body portion and the fixing portion are pre-connected through a rotation shaft portion. Therefore, the deformation into the separated posture or the fixed posture becomes smooth. Thus, the operability of the fixing portion is good, and the movement of the fixing portion is stable.

[0022] In the buckle of the present invention, the main body portion and the fixing portion are connected through an orbit structure, and the fixing portion moves along the orbit structure. When deformed into the separated posture or the fixed posture, due to the friction based on the orbit structure, the fixing portion stops at an arbitrary posture with respect to the main body portion, and the fixing portion does not move accidentally. In addition, since the fixing portion moves along the orbit structure, the operability is good.

[0023] The buckle of the present invention has the main body portion and the fixing portion fitted together in a fixed posture. Therefore, the fixed posture is firm. In addition, it can bring a user a sense of moderation (click feeling) of the fixed posture.

[0024] The buckle of the present invention has the following outer shape: by contacting a restricting portion formed around the bolt to be installed, rotation about the bolt to be installed is restricted. That is, although there is a case where the buckle rotates about the bolt to be installed, the rotation is restricted by the buckle abutting against the restricting portion. Thereby, it is possible to prevent the buckle from accidentally falling off the bolt to be installed.

[0025] The main body portion of the buckle of the present invention has: a side surface portion in which an insertion path is formed; a main body end portion formed at an end portion on the entrance side of the insertion path; the side surface portion has: a claw portion formed on the inner surface of the side surface portion; a rotation shaft portion formed on the outer surface of the side surface portion; a track groove portion formed on the outer surface of the side surface portion and around the rotation shaft portion; a fitting protrusion portion formed on the outer surface of the side surface portion and around the rotation shaft portion; the fixing portion has: an arm portion supported on the rotation shaft portion and facing the outer surface of the side surface portion; a rod portion connected to the arm portion and protruding compared to the main body portion; the arm portion has: a pressing end portion formed at the edge of the arm portion; a track protrusion portion formed on the inner surface of the arm portion and along the track groove portion; a fitting hole portion formed on the inner surface of the arm portion and fitted with the fitting protrusion portion. Thereby, it is possible to fix the member to be installed without shaking on the installation surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] The buckle according to an embodiment of the present invention is used to fix a member to be installed on a mounting surface in the exterior or interior of a vehicle or other transportation means. For example, a double-headed bolt is welded as a bolt to be installed on a vehicle body or bracket as the mounting surface by welding or the like. In a state where the double-headed bolt passes through a member to be installed such as an insulator, a bushing, or an in-seat storage box, the buckle of the present embodiment is installed on the double-headed bolt, so that the member to be installed is fixed on the mounting surface. In addition, since the buckle of the present embodiment is used for all the exterior or interior of the transportation means, the mounting surface or the member to be installed is not limited.

[0052] Hereinafter, the buckle of the present embodiment will be described with reference to the drawings. In Figure 1 and Figure 2 , the appearance of the buckle 10 of the present embodiment is shown. In addition, hereinafter, the direction in which the buckle 10 is inserted into the double-headed bolt for installation is taken as the lower side (Down), the direction in which the buckle 10 is pulled out from the double-headed bolt to be removed is taken as the upper side (Up), and the other directions are taken as the right side (Right Side), the left side (Left Side), the front side (Front Side), and the back side (Back Side) (refer to Figure 1 ).

[0053] In Figure 1 and Figure 2 , the buckle 10 is composed of two members, a main body portion 11 and a fixing portion 30. The main body portion 11 and the fixing portion 30 are pre-connected through a rotating shaft portion 22 of the main body portion 11, and the posture of the buckle 10 changes by rotating the fixing portion 30 relative to the main body portion 11 within a specified range. Since the main body portion 11 and the fixing portion 30 are connected through a track structure (track protrusion 39 and main body track groove portion 25), when the posture of the buckle 10 changes, the fixing portion 30 rotates along the track structure.

[0054] As shown in Figure 1 , the state where the fixing portion 30 is raised is the separated posture. In the separated posture, the fixing portion 30 is separated from the member to be installed 2 (refer toFigure 18 ). On the other hand, as Figure 2 shown, the state where the fixing portion 30 descends is the fixed posture. In the fixed posture, the fixing portion 30 is pressed against the member 2 to be installed (refer to Figure 23 ). In the fixed posture, the main body portion 11 and the fixing portion 30 are fitted to each other through a fitting structure (the fitting protrusion 26 and the fitting hole portion 37).

[0055] Hereinafter, the main body portion 11 and the fixing portion 30 will be described in detail based on the accompanying drawings. In Figures 3 to 7 the main body portion 11 is shown. On the other hand, in Figures 8 to 10 the fixing portion 30 is shown.

[0056] As Figures 3 to 7 shown, the main body portion 11 is substantially rectangular parallelepiped or cube-shaped and is hollow. Inside the main body portion 11, an insertion path 16 through which the double-headed bolt 3 passes is formed through the upper and lower sides. A plurality of claw portions 20 that are caught by the thread groove of the double-headed bolt 3 are arranged in the insertion path 16.

[0057] Specifically, the main body portion 11 has: plate-shaped right side surface portion 12 and left side surface portion 13 that face each other and form the left and right side surfaces of the main body portion 11; a lower surface portion 14 that is connected to the lower ends of the left and right side surface portions 12, 13 and forms the lower surface of the main body portion 11; and an upper surface portion 15 that is connected to the upper ends of the left and right side surface portions 12, 13 and forms the upper surface of the main body portion 11. An insertion path 16 is formed between the left and right side surface portions 12, 13, and the insertion path 16 is configured to include: an entrance side insertion path 17 formed in the lower surface portion 14 and serving as an entrance for the double-headed bolt 3; an intermediate insertion path 18 formed above the entrance side insertion path 17 and in the space between the left and right side surface portions 12, 13; and a cylindrical exit side insertion path 19 formed above the intermediate insertion path 18 and connected to the inner surface of the upper surface portion 15 (refer to Figure 7 ).

[0058] A plurality of claw portions 20 are formed at the front and rear edges of the entrance side insertion path 17 (refer to Figure 4 ), and the claw portions 20 protrude toward the inside of the main body portion 11 (refer to Figure 7 ). In the intermediate insertion path 18, the claw portions 20 formed on the inner surfaces of the left and right side surface portions 12, 13 protrude toward the inside of the main body portion 11. Each claw portion 20 is arranged in a manner of having different heights in the vertical direction (refer to Figure 6 and Figure 7 ).

[0059] On the lower surface portion 14 of the main body portion 11, a main body end portion 21 is formed around the entrance side insertion path 17 (refer to Figure 4 ). The main body end portion 21 is formed by a part of the edge of the lower surface portion 14 bulging downward.

[0060] On the outer surfaces of the left and right side faces 12 and 13, there are provided rotation shaft portions 22, rotation restricting portions 23 formed around the rotation shaft portions 22, main body guide groove portions 24, main body track groove portions 25, and fitting protrusions 26 (see Figure 5 ). Each of the portions 22, 23, 24, 25, and 26 is a left - right pair. The rotation shaft portions 22 are located at the upper - lateral parts of the left and right side faces 12 and 13 and protrude outward from the main body portion 11. The rotation restricting portions 23 are located above the rotation shaft portions 22 and are at the upper - end portions of the left and right side faces 12 and 13, protruding outward from the main body portion 11. The main body guide groove portions 24 are linear and extend in the front - rear direction, located below and rearward of the rotation shaft portions 22. The main body track groove portions 25 are arc - shaped along the circumference centered on the rotation shaft portions 22 and are located in front of the rotation shaft portions 22. There is no groove between the main body guide groove portions 24 and the main body track groove portions 25, thus forming a step portion 27.

[0061] As Figures 8 to 10 shown, the fixing portion 30 has: plate - shaped arm portions 31 opposed to each other on the left and right; and a rod portion 41 connected to the front ends where the arm portions 31 extend. The rod portion 41 has a pressing plate portion 42. When viewed from the left - right direction, the fixing portion 30 is in an L - shape where the arm portions 31 and the rod portion 41 are perpendicularly intersecting and form a right angle (or approximately a right angle) (see Figure 9 ). The arm portions 31 have: a shaft hole portion 34 formed at one end portion 32 (upper end); a corner portion 35 and a pressing end portion 36 formed at the edge of the other end portion 33 (lower end) which is the front end where the arm portion 31 extends from the one end portion 32; a fitting hole portion 37 formed between the shaft hole portion 34 and the pressing end portion 36; and an arm guide groove portion 38, a track protrusion 39, and an arm track groove portion 40 formed on the inner surface of the arm portion 31 (see Figure 10 ). Each of the portions 34, 35, 36, 37, 38, 39, and 40 is a left - right pair.

[0062] As Figure 9 and Figure 10 shown, the corner portion 35 is formed as an obtuse angle with respect to the pressing end portion 36. The shaft hole portion 34, the pressing end portion 36, and the fitting hole portion 37 are arranged in a straight line. The arm guide groove portion 38 is linear and extends outward from the shaft hole portion 34 toward the one end portion 32. The track protrusion 39 is located around the shaft hole portion 34 and is formed at a position protruding outward from the one end portion 32 toward the shaft hole portion 34. The arm track groove portion 40 is arc - shaped along the circumference centered on the shaft hole portion 34 and communicates with the fitting hole portion 37.

[0063] The main body portion 11 and the fixing portion 30 configured as above are connected as follows. Figures 11 to 16 The snap - fit 10 in the assembled state is shown.

[0064] AsFigure 11 As shown, the fixing portion 30 is mounted on the main body portion 11 from the rear in a posture with the arm portion 31 at the bottom and the rod portion 41 at the top. In a state where the rail protrusion 39 of the arm portion 31 abuts against the main body guide groove portion 24 of the main body portion 11 and is guided, the fixing portion 30 is pressed against the main body portion 11. When the rail protrusion 39 passes through the main body guide groove portion 24 and crosses the stepped portion 27 of the main body portion 11, the rotation shaft portion 22 of the main body portion 11 abuts against the arm guide groove portion 38 of the arm portion 31 and is guided. The rail protrusion 39 is disposed in the main body rail groove portion 25 of the main body portion 11, and the rotation shaft portion 22 passes through the arm guide groove portion 38 and is fitted into the shaft hole portion 34 of the arm portion 31.

[0065] When the fixing portion 30 is mounted on the main body portion 11, the arm portion 31 is supported by the rotation shaft portion 22 of the main body portion 11. As Figures 12 to 14 shown, the arm portion 31 faces the outer surfaces of the left and right side surface portions 12, 13 of the main body portion 11 and clamps the main body portion 11. Immediately after the fixing portion 30 is mounted on the main body portion 11, the buckle 10 is in a separated posture. In the separated posture, the fixing portion 30 abuts against the rotation restricting portion 23, and the rotation ( Figure 11 the left-handed rotation in []) is restricted.

[0066] By the rail protrusion 39 of the arm portion 31 following the main body rail groove portion 25 of the main body portion 11 to form a rail structure (refer to Figure 11 ), and by the fitting protrusion 26 of the main body portion 11 following the arm rail groove portion 40 of the arm portion 31 (refer to Figure 10 ), a rail structure is formed. Therefore, when the fixing portion 30 rotates, as Figure 15 shown, the buckle 10 becomes a fixed posture. In the fixed posture, the fitting protrusion 26 is fitted into the fitting hole portion 37. The rod portion 41 protrudes rearward relative to the main body portion 11. As Figure 16 shown, the main body end portion 21 of the main body portion 11 overlaps with the pressing end portion 36 of the arm portion 31, but the pressing end portion 36 protrudes downward by an amount X more than the main body end portion 21.

[0067] As described above, the buckle 10 is constituted. Next, the usage sequence and operation status of the buckle 10 will be described together with the effects of the present embodiment. Figures 17 to 24 The usage sequence and operation process of the buckle 10 are shown.

[0068] As Figure 17 shown, a stud bolt 3 is welded to the mounting surface 1, and the stud bolt 3 passes through the mounted member 2. In this state, the buckle 10 in the separated posture is mounted on the stud bolt 3. The lower surface portion 14 of the main body portion 11 faces the mounted member 2, and the stud bolt 3 is inserted through the inlet side insertion path 17 of the insertion path 16 (refer to Figure 4 ).

[0069] As shown Figure 18 , the buckle 10 is pressed until the main body end 21 of the main body portion 11 abuts against the member 2 to be installed. Since a plurality of claw portions 20 are arranged in the insertion path 16 (refer to Figure 6 and Figure 7 ), the claw portions 20 are caught in the thread grooves of the stud bolts 3. At this time, in a state where the main body end 21 abuts against the member 2 to be installed, the claw portions 20 are caught in the thread grooves of the stud bolts 3. On the other hand, depending on the pitch of the thread grooves, there may also be a case where: the main body end 21 slightly separates from the member 2 to be installed, and there is a gap between the main body end 21 and the member 2 to be installed. In this case, the claw portions 20 are caught in the thread grooves of the stud bolts 3.

[0070] As shown Figure 19 and Figure 20 , the fixing portion 30 rotates (right rotation in these figures). As shown Figure 21 and Figure 22 , the corner portion 35 of the arm portion 31 abuts against the member 2 to be installed. Further, when the pressing end portion 36 of the arm portion 31 starts to abut against the member 2 to be installed, the main body portion 11 is pressed in a direction away from the member 2 to be installed through the arm portion 31 by pressing the pressing end portion 36 against the member 2 to be installed. At this time, since the corner portion 35 is an obtuse angle with respect to the pressing end portion 36, the arm portion 31 slides smoothly with respect to the member 2 to be installed. As shown Figure 23 and Figure 24 , when the fixing portion 30 rotates further and the buckle 10 is deformed into a fixed posture, the pressing end portion 36 is pressed against the member 2 to be installed, and the main body portion 11 is separated from the member 2 to be installed through the arm portion 31 (refer to the gap G in these figures). That is, since the arm portion 31 presses in a direction separating the member 2 to be installed and the main body portion 11, the claw portions 20 are caught in a state suitable for the pitch of the thread grooves. Thus, the member 2 to be installed is fixed to the installation surface 1 without shaking.

[0071] Specifically, in the separated posture of the buckle 10, the main body end 21 abuts against (or approaches) the member 2 to be installed. When deformed into the fixed posture, since the pressing end portion 36 abuts against the member 2 to be installed, the protrusion amount (the degree of protruding with respect to the member 2 to be installed) X is such that the pressing end portion 36 is more than the main body end 21 (refer to Figure 16 ). Therefore, in the fixed posture, when the pressing end portion 36 is pressed against the member 2 to be installed, the main body end 21 separates from the member 2 to be installed by an amount corresponding to the difference in the protrusion amount X, and the main body portion 11 is pressed in a direction away from the member 2 to be installed.

[0072] Since the rod portion 41 is connected to the arm portion 31, when the fixing portion 30 is operated, the pressing plate portion 42 of the rod portion 41 is pressed. Thus, the operation of the user becomes smooth. As long as the fixing portion 30 is in a state of being pre-mounted on the main body portion 11, after the buckle 10 is mounted on the double-headed bolt 3, as long as the fixing portion 30 is rotated, the buckle 10 is deformed. Therefore, the deformation towards the separating posture or the fixing posture becomes smooth. Thus, the operability of the fixing portion 30 is good and the operation of the fixing portion 30 is stable.

[0073] On the outer surface of the main body portion 11, a main body rail groove portion 25 is formed (refer to Figure 5 ), on the other hand, on the inner surface of the arm portion 31, a rail protrusion portion 39 is formed (refer to Figure 10 ), so that a rail structure is formed by the rail protrusion portion 39 along the main body rail groove portion 25 (refer to Figure 11 ). Further, on the outer surface of the main body portion 11, a fitting protrusion portion 26 is formed (refer to Figure 5 ), on the other hand, on the inner surface of the arm portion 31, an arm rail groove portion 40 is formed (refer to Figure 10 ), so that a rail structure is also formed by the fitting protrusion portion 26 along the arm rail groove portion 40. Therefore, when deforming into the separating posture or the fixing posture, due to the friction based on the rail structure, the fixing portion 30 stops relative to the main body portion 11 in any posture and the fixing portion 30 does not rotate accidentally. In addition, since the fixing portion 30 moves along the rail structure, the operability is good.

[0074] On the outer surface of the main body portion 11, a fitting protrusion portion 26 is formed (refer to Figure 5 ), on the arm portion 31, a fitting hole portion 37 is formed (refer to Figure 10 ), and a fitting structure is formed by the fitting protrusion portion 26 and the fitting hole portion 37 (refer to Figure 2 ), so that in the fixing posture, the fitting protrusion portion 26 is fitted with the fitting hole portion 37. Therefore, the fixing posture is firm. In addition, a moderate feeling (click feeling) of the fixing posture can be brought to the user.

[0075] Since the double-headed bolt 3 is a cylindrical shape formed with a thread groove, there is a case where the buckle 10 rotates relative to the double-headed bolt 3. However, the main body portion 11 of the buckle 10 is a cuboid or a cube, and the fixing portion 30 has an outer shape provided with a rod portion 41 extending from the main body portion 11, etc. Therefore, as Figure 25As shown, by contacting the restricting portion 4 around the stud bolt 3, the rotation of the buckle 10 is restricted. Thereby, the situation where the buckle 10 accidentally detaches from the stud bolt 3 is prevented. In other words, by providing the restricting portion 4 on the trajectory when the buckle 10 rotates about the stud bolt 3, a buckle structure is achieved. Additionally, as long as it is on the trajectory when the buckle 10 rotates, the restricting portion 4 can be formed on the mounted member 2, formed on the mounting surface 1, or extended from a member other than the mounted member 2 and the mounting surface 1 and disposed around the buckle 10 in any one of these manners.

[0076] In addition, in other embodiments of the present invention, the main body portion and the fixing portion are detachable from each other, and after the main body portion is mounted on the stud bolt, the fixing portion is mounted on the main body portion.

[0077] In other embodiments, the fixing portion does not rotate relative to the main body portion, but slides linearly to change its posture.

[0078] In other embodiments, the protruding amount of the pressing end portion of the fixing portion and the main body end portion of the main body portion is the same, or the protruding amount of the main body end portion is more. In this case, among the mounted members, the portion pressed by the pressing end portion bulges by an amount corresponding to the difference in the protruding amount.

[0079] In other embodiments, the main body track groove portion is not formed on the main body portion, and the track protrusion portion is not formed on the arm portion, so there is no track structure.

[0080] In other embodiments, the fitting protrusion portion is not formed on the main body portion, and the fitting hole portion is not formed on the arm portion of the fixing portion, so the main body portion and the fixing portion are not fitted in the fixed posture.

[0081] In other embodiments, there is no restricting portion.

[0082] In other embodiments, a shaft hole portion is formed on the outer surface of the main body portion, and a rotating shaft portion is formed on the arm portion of the fixing portion.

[0083] In other embodiments, a fitting hole portion is formed on the main body portion, and a fitting protrusion portion is formed on the arm portion of the fixing portion.

[0084] In other embodiments, the main body portion is cylindrical or polygonal prism-shaped.

[0085] Other embodiments have front and rear side faces.

[0086] In other embodiments, when viewed from the left-right direction, the arm portion and the rod portion of the fixing portion intersect at an acute or obtuse angle.

[0087] In other embodiments, as long as the main body portion and the fixing portion are fitted in a fixed posture, the positions of the fitting protrusions of the main body portion and the fitting holes of the arm portion can be arbitrary.

[0088] In other embodiments, the corners are arc-shaped with chamfers being arcs.

[0089] In other embodiments, the fixing portion does not have a rod portion.

[0090] The embodiments of the present invention have been described in detail above, but the present invention is not limited to the above embodiments. Therefore, various design changes can be made as long as the present invention does not depart from the matters described in the scope of claims. The vehicles equipped with the embodiments of the present invention include, for example, trains, ships, aircraft, etc.
