[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 57-090224 Summary of the Invention [Problem to be solved by the invention]
[0004] However, there is a risk that a gap may occur between the end of the collar and the bracket or washer due to, for example, dimensional errors, etc. If such a gap occurs, vibrations may cause the ends of the collar to collide with the bracket or washer while the vehicle is running, which could result in abnormal noise.
[0005] In one aspect of the present disclosure, it is desirable to suppress the generation of abnormal noise. [Means for solving the problem]
[0006] One aspect of the present disclosure is a support device configured to support an exhaust part through which vehicle exhaust flows, the support device comprising a hanger member, a bracket, a collar, a facing portion, and a fastener. The hanger member is configured to be supported by a vehicle-side support member provided on the vehicle. The bracket is configured to be attached to the exhaust part. The collar is a tubular member having first and second ends located at both ends in the length direction and configured to penetrate the hanger member. The facing portion is arranged to face the hanger member. The fastener penetrates the collar and the bracket with the hanger member positioned between the facing portion and the bracket, and fastens the hanger member to the bracket. The first and second ends of the collar abut against the facing portion and the bracket, respectively, and the collar presses the facing portion and the bracket by elastic force.
[0007] The above configuration helps maintain contact between both ends of the collar and the facing portion and bracket, thereby preventing gaps from forming between both ends of the collar and the facing portion or bracket, and suppressing noise caused by collision between the collar and the facing portion or bracket.
[0008] In one aspect of the present disclosure, the bracket may have first and second wall portions arranged opposite each other. The first wall portion may constitute the opposing portion. The fastener may fasten the hanger member to the bracket by passing through the collar and the first and second wall portions with the hanger member positioned between the first and second wall portions. The first and second ends of the collar may abut against the first and second wall portions, respectively, and the collar may press against the first and second wall portions by elastic force.
[0009] The above configuration helps maintain contact between both ends of the collar and the first and second wall portions of the bracket, thereby preventing gaps from forming between both ends of the collar and the first or second wall portion and suppressing noise caused by collision between the collar and the bracket.
[0010] In one aspect of the present disclosure, the collar may be configured to have elasticity by shortening the collar in a longitudinal direction in an initial state. The collar in the initial state may be provided such that the first and second ends protrude from an outer surface of the hanger member.
[0011] According to the above configuration, it is possible to encourage both ends of the collar to come into contact with the facing portion and the bracket, thereby more effectively suppressing the generation of abnormal noise due to a collision between the collar and the bracket.
[0012] In one aspect of the present disclosure, the collar may have elasticity by shortening the collar in the length direction in an initial state. The collar in the initial state may extend from a first end to a second end and have first and second abutting surfaces that extend from the inner peripheral surface to the outer peripheral surface of the collar and face each other in the circumferential direction. The first abutting surface may be located on a first side, and the second abutting surface may be located on a second side. At the first end, a portion adjacent to the first side of the first abutting surface may protrude beyond a portion adjacent to the second side of the second abutting surface. At the second end, a portion adjacent to the second side of the second abutting surface may protrude beyond a portion adjacent to the first side of the first abutting surface.
[0013] According to the above configuration, the collar can be made elastic with a simple configuration. In one aspect of the present disclosure, the collar is a tubular member used in a support device configured to support an exhaust part through which vehicle exhaust flows. The support device includes a hanger member, a bracket, a facing portion, and a fastener. The hanger member is configured to be supported by a vehicle-side support member provided on the vehicle. The bracket is configured to be attached to the exhaust part. The facing portion is arranged to face the hanger member. The fastener penetrates the collar and the bracket with the hanger member positioned between the facing portion and the bracket, and fastens the hanger member to the bracket. The collar has first and second ends located at both ends in the length direction and is arranged to penetrate the hanger member. The first and second ends of the collar abut against the facing portion and the bracket, respectively, and the collar is configured to press the facing portion and the bracket by elastic force.
[0014] The above configuration helps maintain contact between both ends of the collar and the facing portion and bracket, thereby preventing gaps from forming between both ends of the collar and the facing portion or bracket, and suppressing noise caused by collision between the collar and the facing portion or bracket.

FIG. DETAILED DESCRIPTION OF THE INVENTION
[0016] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. Note that the embodiments of the present disclosure are not limited to the following embodiments, and various forms may be adopted as long as they fall within the technical scope of the present disclosure.
[0017] [1. Configuration of the support device] The support device 1 of this embodiment is configured to support an exhaust part of a vehicle (see FIG. 1). An exhaust part is a part that allows exhaust gas from a vehicle engine to flow downstream. In this embodiment, the support device 1 supports a muffler 6, for example. However, the support device 1 may also be configured to support an exhaust pipe, for example.
[0018] The muffler 6 comprises a cylindrical muffler shell 60 with a substantially elliptical cross section, and first and second end plates 61, 62 that cover both ends of the muffler shell 60. Support devices 1 are attached to each of the first and second end plates 61, 62. These support devices 1 are also attached to rod-shaped vehicle-side support members 7 provided on the vehicle body, and support the muffler 6. Note that the support devices 1 may also be attached to the muffler shell 60, for example.
[0019] The support device 1 includes a hanger member 2, a bracket 3, a collar 4, and a fastener 5. These components of the support device 1 will be described below. [2. Hanger parts] The hanger member 2 is an elastic member, and is made of rubber, for example. The hanger member 2 is a substantially elliptical member, and is arranged, for example, with its major axis extending vertically when mounted on a vehicle. The hanger member 2 has an upper hole 20, a lower hole 21, a central hole 22, a first surface 23, a second surface 24, and a side surface 25 (see FIGS. 2 and 3).
[0020] The first and second surfaces 23, 24 and the side surface 25 form the outer surface of the hanger member 2. The first and second surfaces 23, 24 have substantially elliptical outer edges and face each other in the thickness direction of the hanger member 2. The side surface 25 extends in the thickness direction from the outer edge of the first surface 23 to the outer edge of the second surface 24.
[0021] The central hole 22 is located in the center of the first and second surfaces 23, 24, and penetrates the hanger member 2 in the thickness direction from the first surface 23 to the second surface 24. Upper hole 20 is located above central hole 22 and penetrates hanger member 2 in the thickness direction from first surface 23 to second surface 24. A rod-shaped vehicle-side support member 7 is inserted into upper hole 20, and hanger member 2 is supported by vehicle-side support member 7.
[0022] The lower hole 21 is located below the central hole 22 and penetrates the hanger member 2 in the thickness direction from the first surface 23 to the second surface 24. The above-mentioned collar 4 (details will be described later) is inserted into the lower hole 21 so as to penetrate the hanger member 2.
[0023] [3. Bracket] The bracket 3 is attached to the first or second end plate 61, 62 of the muffler 6, which is an exhaust component, and is fastened to the hanger member 2 (see FIGS. 2 to 4). The bracket 3 includes first to fourth wall portions 30 to 33, which are plate-like portions configured to accommodate the lower portion of the hanger member 2, and a bottom portion 34, as well as first and second mounting portions 35, 36.
[0024] The first to fourth walls 30 to 33 are located on the sides of the accommodated hanger member 2. The first and second walls 30 and 31 face the first and second surfaces 23 and 24 of the hanger member 2, respectively. The first and second walls 30 and 31 may abut against the first and second surfaces 23 and 24, respectively, or a gap may be formed between the first wall 30 and the first surface 23 and between the second wall 31 and the second surface 24. The first and second walls 30 and 31 are arranged to cover the lower hole 21 of the hanger member 2, and have holes 30A and 31A penetrating through the lower hole 21. The fastener 5 described above is inserted through the holes 30A and 31A.
[0025] On the other hand, the third and fourth wall portions 32, 33 extend from each edge portion aligned in the lateral direction (in other words, the horizontal direction when mounted on the vehicle) of the second wall portion 31 toward the first wall portion 30 and face the side surface 25 of the hanger member 2.
[0026] The bottom portion 34 extends from the lower edge of the second wall portion 31 to the lower edge of the first wall portion 30. The bottom portion 34 is located below the hanger member 2 and faces the side surface 25 of the hanger member 2. The first and second mounting portions 35, 36 are plate-like portions that extend from the upper edges of the first and second wall portions 30, 31, respectively, and extend laterally. The first and second mounting portions 35, 36 are joined to the first and second end plates 61, 62, respectively, of the muffler 6. Note that the bracket 3 may be provided with only one of the first and second mounting portions 35, 36.
[0027] [4. Color] The collar 4 is a cylindrical metallic member that passes through the hanger member 2 (see FIGS. 3 to 5). The collar 4 is inserted into the lower hole 21 and fixed to the hanger member 2. In this embodiment, the collar 4 is formed in a cylindrical shape, for example. Hereinafter, both ends of the collar 4 in the longitudinal direction will be referred to as first and second ends 40 and 41, respectively.
[0028] The first and second ends 40, 41 of the collar 4 are located on the first surface 23 side and the second surface 24 side of the hanger member 2, respectively, and abut against the first and second wall portions 30, 31. As will be described in detail later, the collar 4 is arranged in a shortened state in the longitudinal direction, which gives the collar 4 an elastic force that stretches the collar 4. Therefore, the first and second ends 40, 41 press against the first and second wall portions 30, 31, respectively.
[0029] Here, the state of the collar 4 before being shortened is referred to as the initial state. The collar 4 in the initial state is formed by bending a rectangular plate-shaped member and butting together two end faces that form two opposing sides of the plate-shaped member. Hereinafter, the two butted end faces of the collar 4 will be referred to as the first and second butt faces 42, 43. In the initial state of the collar 4, the first and second butt faces 42, 43 extend linearly in the longitudinal direction from the first end 40 to the second end 41, extend from the inner peripheral surface to the outer peripheral surface of the collar 4, and face each other in the circumferential direction. Hereinafter, the side where the first butt face 42 is located will be referred to as the first side, and the side where the second butt face 43 is located will be referred to as the second side (see FIG. 5).
[0030] The first and second abutting surfaces 42, 43 may be in contact with each other, or a small gap may be formed between the first and second abutting surfaces 42, 43. The first and second abutting surfaces 42, 43 may be inclined relative to the longitudinal direction, or may have a curved or bent shape, for example.
[0031] Furthermore, in the first end 40 of the collar 4 in the initial state, a step is formed by the first abutting surface 42. Specifically, in the first end 40, a portion adjacent to the first side of the first abutting surface 42 (hereinafter referred to as the first step portion 40A) protrudes further toward the first end 40 than a portion adjacent to the second side of the second abutting surface 42. In other words, the first end 40 extends in a spiral shape from the portion adjacent to the second side of the second abutting surface 42 to the first step portion 40A.
[0032] Furthermore, even in the second end 41 of the collar 4 in the initial state, a step is formed by the second abutting surface 43. Specifically, in the second end 41, a portion adjacent to the second side of the second abutting surface 43 (hereinafter, the second step portion 41A) protrudes further toward the second end 41 than a portion adjacent to the first side of the first abutting surface 42. In other words, the second end 41 extends in a spiral shape from the portion adjacent to the first side of the first abutting surface 42 to the second step portion 41A.
[0033] According to the above configuration, the collar 4 in the initial state is longer in the length direction and more susceptible to elastic deformation than a collar that does not have the steps at the first and second ends 40, 41. [5. Color Variations] The collar 4 is not limited to the above-described configuration, and may have various configurations that can generate an elastic force that stretches the collar 4. For example, the cross section of the collar 4 perpendicular to the longitudinal direction may be polygonal, or a slit may be formed in the collar 4.
[0034] Specifically, for example, first and second slits 44, 45 may be provided near the first and second ends 40, 41 of the collar 4, respectively (FIGS. 6 and 7). The first and second slits 44, 45 are elongated holes that penetrate the collar 4 from the inner peripheral surface to the outer peripheral surface of the collar 4. The first slit 44 extends in the circumferential direction from the first abutting surface 42 to the first side, and the second slit 45 extends in the circumferential direction from the second abutting surface 43 to the second side.
[0035] Alternatively, for example, third and fourth slits 46 and 47 may be provided in the first and second ends 40 and 41 of the collar 4, respectively (FIGS. 8 and 9). The third and fourth slits 46 and 47 are also elongated holes that penetrate the collar 4, similar to the first and second slits 44 and 45. The third slit 46 is provided at a position facing the first and second abutting surfaces 42 and 43 across the center of the collar 4, and extends in the length direction from the first end 40. The fourth slit 47 is provided at a position facing the first and second abutting surfaces 42 and 43 across the center of the collar 4, and extends in the length direction from the second end 41.
[0036] [6. Fasteners] The fastener 5 includes a bolt 50 and a nut 53, and fastens the hanger member 2 to the bracket 3 (see FIGS. 2 and 3).
[0037] Specifically, the bolt 50 has a head 51 and a cylindrical threaded portion 52 protruding from the head 51. Meanwhile, the hanger member 2 is located between the first and second wall portions 30, 31 of the bracket 3. The hanger member 2 may be in contact with the first and second wall portions 30, 31, or a gap may be formed between the hanger member 2 and each of the first and second wall portions 30, 31.
[0038] The screw portion 52 passes through the hole 30A in the first wall portion 30 and the hole 31A in the second wall portion 31 of the bracket 3, and the collar 4 provided in the lower hole 21 of the hanger member 2. At this time, the head portion 51 abuts against the first wall portion 30, and the first wall portion 30 is sandwiched between the head portion 51 and the first end portion 40 of the collar 4. The nut 53 is threadedly engaged with the screw portion 52 and abuts against the second wall portion 31, and the second wall portion 31 is sandwiched between the nut 53 and the second end portion 41 of the collar 4.
[0039] [7. Manufacturing method of support device] The supporting device 1 is manufactured in the following manner. First, the collar 4 in its initial state is press-fitted into the lower hole 21 of the hanger member 2. As a result, the collar 4 is provided in the lower hole 21, passing through the hanger member 2 and being fixed to the hanger member 2. The collar 4 is longer than the thickness of the hanger member 2, and when the collar 4 is provided in the lower hole 21, the first and second ends 40, 41 of the collar 4 protrude from the first and second surfaces 23, 24 of the hanger member 2, respectively (see FIG. 4). Of course, this is not a limitation, and the first and second ends 40, 41 do not have to protrude from the first and second surfaces 23, 24.
[0040] Next, the hanger member 2 provided with the collar 4 is placed between the first and second wall portions 30, 31 of the bracket 3 (see FIG. 4). Specifically, the lower portion of the hanger member 2 is placed inside the first to fourth wall portions 30-33 and the bottom portion 34 of the bracket 3. At this time, the upper portion of the hanger member 2 is located above the first and second mounting portions 35, 36, and the upper hole portion 20 is exposed. In addition, the first surface 23 of the hanger member 2 faces the first wall portion 30, and the second surface 24 faces the second wall portion 31. In addition, the third and fourth wall portions 32, 33 and the bottom portion 34 of the bracket 3 face the side surface 25 of the hanger member 2.
[0041] Next, the bolt 50 is arranged so as to penetrate the first and second wall portions 30, 31 and the collar 4 (see FIGS. 2 and 3). Specifically, the threaded portion 52 of the bolt 50 is inserted into the hole 30A in the first wall portion 30 of the bracket 3, the collar 4 provided on the hanger member 2, and the hole 31A in the second wall portion 31. At this time, the head portion 51 of the bolt 50 faces the first wall portion 30.
[0042] Next, the first and second wall portions 30, 31 of the bracket 3 and the hanger member 2 disposed between the first and second wall portions 30, 31 are fastened together by the fastener 5 (see FIGS. 2 and 3). Specifically, the threaded portion 52 of the bolt 50 is screwed into the nut 53. At this time, the nut 53 faces the second wall portion 31.
[0043] Then, by tightening the bolt 50, the head 51 and the nut 53 are brought closer together, causing the head 51 to press against the first wall portion 30 and the nut 53 to press against the second wall portion 31. This causes the bracket 3 to deform, bringing the first and second wall portions 30, 31 closer together. As a result, the first and second wall portions 30, 31 come into contact with the first and second end portions 40, 41 of the collar 4, respectively, and press the first and second end portions 40, 41.
[0044] As a result, the collar 4 is shortened in the length direction, and the collar 4 assumes a state in which it has an elastic force that extends the collar 4. Then, the first and second ends 40, 41 of the collar 4 come into contact with the first and second wall portions 30, 31, respectively, and press the first and second wall portions 30, 31 by the elastic force.
[0045] As described above, in the initial state, the first and second ends 40, 41 of the collar 4 have a step formed by the first and second step portions 40A, 40B, respectively. Then, by tightening the bolt 50, the first and second step portions 40A, 40B of the collar 4 are pressed, reducing the step between the first and second ends 40, 41. The collar 4 may be shortened until the step between the first and second ends 40, 41 disappears, or until a slight step remains at the first and second ends 40, 41.
[0046] [8. Effects] (1) According to the above embodiment, the first and second end portions 40, 41 of the collar 4 press the first and second wall portions 30, 31 of the bracket 3 by elastic force, respectively. This helps maintain contact between the first and second end portions 40, 41 and the first and second wall portions 30, 31. This prevents gaps from being formed between the first and second end portions 40, 41 and the first and second wall portions 30, 31, and prevents noise caused by a collision between the collar 4 and the bracket 3.
[0047] (2) Furthermore, the first and second ends 40, 41 of the collar 4 in the initial state are provided so as to protrude from the first and second surfaces 23, 24, respectively, of the hanger member 2. This encourages the first and second ends 40, 41 to abut against the first and second wall portions 30, 31, respectively, thereby more effectively suppressing the generation of abnormal noise due to collision of the collar 4 with the bracket 3.
[0048] (3) Furthermore, steps are formed at the first and second ends 40, 41 of the collar 4 in the initial state, with the first step portion 40A of the first end 40 protruding toward the first end 40 and the second step portion 41A of the second end 41 protruding toward the second end 41. This simple configuration allows the collar 4 to be elastic when the hanger member 2 and the bracket 3 are fastened together.
[0049] 9. Other Embodiments (1) In the above embodiment, the hanger member 2 is disposed between the first and second wall portions 30, 31 of the bracket 3. However, this is not limiting, and for example, the bracket 3 may be configured without the first wall portion 30. For example, a ring-shaped washer 54 may be disposed between the head 51 of the bolt 50 and the first surface 23 of the hanger member 2 (see FIG. 10 ). That is, the bolt 50 may penetrate the washer 54, the second wall portion 31, and the hanger member 2 located between the washer 54 and the second wall portion 31, and the hanger member 2 may be fastened to the second wall portion 31. The first and second ends 40, 41 of the collar 4 may contact the washer 54 and the second wall portion 31, respectively, and press the washer 54 and the second wall portion 31 by elastic force.
[0050] In this case, the support device 1 is manufactured in the following procedure. First, the collar 4 is provided on the hanger member 2 in the same manner as in the above embodiment. Next, the threaded portion 52 of the bolt 50 is positioned so as to penetrate the washer 54, the second wall portion 31, and the collar 4 in its initial state, which is positioned between the washer 54 and the second wall portion 31. At this time, the head 51 of the bolt 50 faces the washer 54.
[0051] Next, the second wall portion 31 and the hanger member 2 are fastened together with the fastener 5. Specifically, the threaded portion 52 of the bolt 50 is screwed into the nut 53. At this time, the nut 53 faces the second wall portion 31. Then, by tightening the bolt 50, the head portion 51 and the nut 53 are brought closer together, causing the head portion 51 to press the washer 54, and the nut 53 to press the second wall portion 31. As a result, the washer 54 and the second wall portion 31 press the first and second ends 40 and 41 of the collar 4, respectively, causing the collar 4 to shorten in the longitudinal direction and resulting in the collar 4 having an elastic force that causes the collar 4 to extend.
[0052] In the case of such a configuration, the same effect can be obtained. (2) In addition to this, in the configuration of (1) above, the hanger member 2 may be fastened to the bracket 3 without using the washer 54 (see FIG. 11). That is, the bolt 50 may penetrate the second wall portion 31 and the hanger member 2 with the head portion 51 adjacent to the first surface 23 of the hanger member 2, and fasten the hanger member 2 to the second wall portion 31. The first and second ends 40, 41 of the collar 4 may then abut against the head portion 51 and the second wall portion 31, respectively, and press the head portion 51 and the second wall portion 31 together by elastic force.
[0053] In this case, the support device 1 is manufactured in the following procedure. First, the collar 4 is provided on the hanger member 2 in the same manner as in the above embodiment. Next, the threaded portion 52 of the bolt 50 is positioned so as to penetrate the collar 4 in its initial state and the second wall portion 31. At this time, the head 51 of the bolt 50 faces the first surface 23 of the hanger member 2.
[0054] Next, the second wall portion 31 and the hanger member 2 are fastened together by the fastener 5. Specifically, the threaded portion 52 of the bolt 50 is screwed into the nut 53. At this time, the nut 53 faces the second wall portion 31. Then, by tightening the bolt 50, the head portion 51 and the nut 53 are brought closer together, and the nut 53 presses against the second wall portion 31. As a result, the head portion 51 and the second wall portion 31 press against the first and second ends 40 and 41 of the collar 4, respectively, which shortens the collar 4 in the longitudinal direction and causes the collar 4 to have an elastic force that stretches the collar 4.
[0055] In the case of such a configuration, the same effect can be obtained. (3) Multiple functions of one component in the above embodiments may be realized by multiple components, or one function of one component may be realized by multiple components. Also, multiple functions of multiple components may be realized by one component, or one function realized by multiple components may be realized by one component. Also, part of the configuration of the above embodiments may be omitted. Also, at least part of the configuration of the above embodiments may be added to or substituted for the configuration of another of the above embodiments.
[0056] [10. Correspondence of Wording] The first wall portion 30 of the bracket 3, the washer 54, or the head portion 51 of the bolt 50 in the above embodiment corresponds to an example of the facing portion. [Explanation of symbols]
