Description

  The present invention relates to a fixing member for a pendulum damping damper and a pendulum damping damper.

  In general, in an automobile equipped with an engine, by driving the engine, wheels are driven via a crankshaft, an input shaft of a transmission, a drive shaft, or a component that is attached to and rotates integrally with the crankshaft. However, when driving the engine, it is known that torsional vibration according to the number of cylinders of the engine is transmitted to the crankshaft and the like, causing a number of problems such as a decrease in ride comfort and abnormal noise in the transmission. . Therefore, many dynamic dampers that are attached to a rotating body such as a crankshaft and absorb or attenuate torsional vibrations of the rotating body have been proposed.

  For example, a pendulum damping damper 500 disclosed in Patent Document 1 shown in FIG. 7 includes four weight assemblies (pendulums) 503 in the rotor 501. The pendulum 503 includes a pair of pendulum mass bodies 505 that are coupled with the rotor 501 sandwiched in the axial direction, pins (rollers) 507, and a mass body coupling member (not shown). The pair of pendulum mass bodies 505 constitutes a pendulum 503 by being connected by a connecting element 509 via a mass body connecting member.

  The pendulums 503 supported by the rotor 501 can reciprocate along the circumferential direction of the rotor 501, that is, can swing. The pair of pendulum mass bodies 505 are formed with arc-shaped tracks 513 at both ends thereof. A pin 507 is inserted into each track 513, and the inner peripheral surface of the track 513 becomes the track surface of the pin 507. Since the pin 507 can move in the extending direction of the track 513, the pendulum 503 can swing.

  However, the pendulum type damping damper 500 is often installed between the engine and the transmission and is driven to rotate at a rotational speed equivalent to the engine. For this reason, the centrifugal force acting on the pendulum 503 may become very large as the rotational speed of the engine increases. In that case, since the pendulum 503 is supported by the rotor 501 via the pin 507, the surface pressure at the contact portion between the rotor 501 and the pin 507 and between the pin 507 and the pendulum 503 becomes very high. In general, the pendulum damping damper 500 is transported from a manufacturing factory to an automobile assembly factory and assembled to a vehicle. However, when the pendulum type damping damper 500 is transported and stored, scratches such as indentations may occur on contact portions (such as the raceway surface) of the rotor 501 and the pin 507 and the pin 507 and the pendulum 503 due to vibration during transportation or unexpected vibration. There is a risk of getting on. When these contact portions are damaged, the life of the pendulum damping damper 500 is greatly affected.

  The present invention has been made in view of the above situation, and its purpose is to position the relative positions of the rotor, the pin, and the pendulum at least in the radial direction of the rotor, and prevent damage to each contact portion. An object of the present invention is to provide a fixing member for a pendulum type damping damper and a pendulum type damping damper.

The present invention has the following configuration.
(1) A plurality of pendulums are provided on the outer peripheral edge of the annular plate-shaped rotor having a through hole coaxial with the rotation center, and are supported so as to be reciprocable in the circumferential direction of the rotor. A plurality of support holes that respectively support the plurality of pendulums are formed, and the pendulum is arranged to face the outer side in the axial direction of the rotor, with a pin penetrating through the support hole with play. A pendulum type vibration damper having an axial end portion engaged with play and a pair of mass bodies formed with at least two positioning recesses, the axial direction of the pendulum type vibration damper A member for fixing a pendulum type damping damper that is arranged on both sides and fixes the pendulum to the rotor,
The fixing member is
An insertion protrusion that protrudes outward in the axial direction at a corresponding position of the through hole of the rotor and engages with the through hole;
A plurality of pin restricting protrusions protruding outward in the axial direction at corresponding positions of the plurality of pins, and engaging with axial ends of the pins;
A plurality of pendulum restricting protrusions that protrude outward in the axial direction at positions corresponding to the positioning recesses of the mass body and engage with the positioning recesses;
A member for fixing a pendulum type damping damper.
(2) The pendulum type damping damper in which the rotor, the pin, and the pendulum are positioned by a fixing member of the pendulum type damping damper.

  According to the present invention, the relative positions of the rotor, the pin, and the pendulum can be positioned at least in the radial direction of the rotor by the fixing member, and damage to each contact portion can be prevented. Thereby, shortening of the lifetime of a pendulum type damping damper can be suppressed.

(A) is a front view of the fixing member shown in FIG. 1, and (B) is a cross-sectional view taken along line AA of (A). It is a front view which shows the state which fixed the pendulum type damping damper shown in FIG. 1 with a pair of fixing member. FIG. 4 is a cross-sectional view taken along line B-O-C in FIG. 3. It is a principal part enlarged view corresponding to the BO line cross section shown in FIG. It is a principal part enlarged view corresponding to the CO line cross section of FIG. It is a front view of the conventional pendulum type damping damper.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
<First configuration example>
FIG. 1 is an exploded perspective view showing a fixing member of a first configuration example together with a pendulum type damping damper.
The fixing member 100 of the pendulum type damping damper of this configuration is used when the pendulum type damping damper 200 is transported and stored.

  Prior to the description of the fixing member 100, first, a schematic configuration of the pendulum type damping damper 200 will be described. The pendulum type damping damper 200 is used to reduce rotational vibrations in a drive machine, for example, constant order rotational fluctuations generated in an internal combustion engine such as an automobile engine.

  The rotor 11 is formed of an annular plate-like member in which a through hole 13 coaxial with the rotation center is formed at the center. On the inner peripheral side of the rotor 11, a plurality of fixed holes 15 for power transmission are arranged at equal intervals in the circumferential direction. The rotor 11 is coaxially fixed to a flywheel (not shown) or the like through these fixing holes 15. The rotor 11 has a pair of leg portions 17A and 17B that protrude radially outward from both ends in the diameter direction. The leg portions 17A and 17B abut on an elastic member (not shown) provided in the power transmission path in the circumferential direction of the rotor 11. As the elastic member, a compression coil spring that attenuates and absorbs engine vibration and rotational non-periodicity is used.

  A plurality of pendulums 19 are supported on the outer peripheral edge of the rotor 11 so as to be swingable in the circumferential direction. In the illustrated example, four pendulums 19 are provided as an example. A support hole 21 (see FIG. 4) is formed in the rotor 11 corresponding to each pendulum 19, and the pendulum 19 is supported in the support hole 21. The pendulums 19 supported by the rotor 11 can reciprocate along the circumferential direction of the rotor 11, that is, swing around the support hole 21.

  The pendulum 19 is configured such that a pair of mass bodies 23 face each other on the radially outer side of the outer peripheral edge portion of the rotor 11, and the pair of mass bodies 23 sandwich the outer peripheral edge portion of the rotor 11 in the axial direction. The pair of mass bodies 23 are plate members having the same arc shape. The pendulum 19 is connected in a state where a pair of mass bodies 23 are overlapped in the plate thickness direction by a connecting element (not shown). For example, the pair of mass bodies 23 are sandwiched between spacers, collars, and the like between the opposing surfaces, and are fixed together by a connecting element such as a rivet with a predetermined constant interval.

  A plurality of (for example, two) concave grooves 25 extending in an arc shape are formed in the pair of mass bodies 23. The concave groove 25 is a groove that penetrates the mass body 23 in the thickness direction, but may be a bottomed concave groove. A pin 27 is inserted into each concave groove 25. The pin 27 is supported so as to be movable along the extending direction of the concave groove 25. In addition, the pin 27 is supported with a play that can move slightly in the radial direction in the concave groove 25 and that can also move slightly in the axial direction.

  In the pair of mass bodies 23, a pair of positioning recesses 47 are formed between the pair of recessed grooves 25 in the circumferential direction. The positioning recess 47 may be a bottomed recess in addition to the through hole.

  The groove side surface of the concave groove 25 of the mass body 23 becomes a raceway surface on which the pin 27 rolls. Moreover, the inner surface of the support hole 21 (refer FIG. 4) of the rotor 11 turns into a track surface on which the pin 27 rolls. That is, the pin 27 is supported so as to be able to roll between the concave groove 25 and the support hole 21, and the rotor 11 and the pin 27, and the pin 27 and the pendulum 19 can be relatively moved. Therefore, in the pendulum type damping damper 200, the rotor 11 and the pin 27, and the pin 27 and the pendulum 19 easily come into contact with each other in the radial direction of the rotor 11 when vibration during transportation or unexpected vibration during storage occurs. It is in a state.

Next, the fixing member 100 will be described.
The fixing member 100 prevents damage to the raceway surface of the pendulum type damping damper 200 when the above-described vibration occurs.

2A is a front view of the fixing member 100 shown in FIG. 1, and FIG. 2B is a cross-sectional view taken along line AA in FIG.
In order to fix one pendulum type damping damper 200, a pair of fixing members 100 arranged with the pendulum type damping damper 200 sandwiched in the axial direction is used. Each fixing member 100 includes a disc-shaped main body 35 having substantially the same outer diameter as the outer peripheral surface of the rotor 11, a pin regulating projection 31 and a pendulum regulating projection 33 formed on the axial end surface of the disc-shaped main body 35, And a boss 40 on the inner side in the radial direction of the disc-shaped main body 35.

  The material of the fixing member 100 is not damaged even if the pendulum 19 and the pin 27 are in contact with each other, and may be light, for example, a resin material. By configuring the fixing member 100 with a resin material, the shapes of the disk-shaped main body 35, the pin restricting protrusion 31, the pendulum restricting protrusion 33, the boss portion 40, and the like can be manufactured with high accuracy by integral molding.

In the boss portion 40 of the fixing member 100, a cylindrical insertion protrusion 37 is formed coaxially on one axial end face side (left side of FIG. 2B) of the disc-shaped main body 35.
On the proximal end side of the insertion protrusion 37, an annular clamping part 41 having a diameter larger than the outer diameter of the insertion protrusion 37 is formed coaxially. The annular clamping portions 41 are formed on both end surfaces in the axial direction of the disc-shaped main body 35, and are formed as pressed portions protruding in the axial direction from the end surfaces in the axial direction of the disc-shaped main body 35. The annular axial end surface of the annular clamping part 41 is a flat surface. An annular fitting groove 43 is formed coaxially on the other axial end face side opposite to the side on which the insertion protrusion 37 is formed. The inner diameter of the fitting groove 43 is substantially equal to the outer diameter of the insertion protrusion 37.

3 is a front view showing a state in which the pendulum type damping damper 200 shown in FIG. 1 is fixed by a pair of fixing members 100, and FIG. 4 is a cross-sectional view taken along line B-O-C in FIG.
Due to the configuration of the boss portion 40, as shown in FIG. 4, the pair of fixing members 100 having the same shape causes the insertion protrusion 37 of one fixing member 100 to be inserted into the rotor 11 of the pendulum type damping damper 200. The pendulum type damping damper 200 can be sandwiched by inserting the insertion protrusion 37 inserted into the formed through-hole 13 and passing through the through-hole 13 into the insertion groove 43 of the other fixing member 100.

  That is, the insertion protrusion 37 and the insertion groove 43 have a spigot structure that is disposed in correspondence with each other when the fixing member 100 is overlapped. Thereby, the peripheral edge part of the inner peripheral side of the rotor 11 can be clamped between the annular clamping parts 41 of the pair of fixing members 100.

  The pair of fixing members 100 are provided with pin restricting protrusions 31 projecting from the both axial end surfaces of the disk-shaped main body 35 toward the outer side in the axial direction. The pin restricting protrusions 31 are provided at corresponding positions that are the same positions as the positions of the pins 27 provided on the respective pendulums 19. That is, the pin 27 and the pin regulation protrusion 31 corresponding to this are arrange | positioned coaxially. The pendulum type damping damper 200 of this configuration includes four pendulums 19, and each pendulum 19 has two pins 27. Accordingly, eight pin restricting protrusions 31 are provided on both end faces in the axial direction of the disk-shaped main body 35 of the fixing member 100.

  Further, in the pair of fixing members 100, the pendulum restricting projections 33 protrude from both end surfaces in the axial direction of the disk-shaped main body 35. The pendulum regulating projection 33 is provided at a corresponding position that is the same position as the arrangement position of the positioning recess 47 provided in each pendulum 19. That is, the positioning recess 47 and the corresponding pendulum restricting projection 33 are arranged coaxially. The pendulum type damping damper 200 of this configuration includes four pendulums 19, and two positioning recesses 47 are provided in each pendulum 19. Accordingly, eight pendulum restricting projections 33 are provided so as to project from both end surfaces in the axial direction of the disk-shaped main body 35 of the fixing member 100.

  Pin end surface recesses 45 are formed on both end surfaces of the pin 27 of the pendulum 19. The pin restricting protrusion 31 is fitted into the pin end surface recess 45 of the corresponding pin 27. Thereby, the pin restricting protrusion 31 determines the radial position of the pin 27 and restricts the radial movement of the pin 27. The pin 27 is disposed so as not to contact the inner peripheral surface of the support hole 21 formed in the rotor 11 in the radial direction.

  Further, as described above, the positioning recess 47 is formed on the outer surface of the mass body 23 of the pendulum 19. The pendulum restricting projection 33 is fitted into the corresponding positioning recess 47. Thereby, the pendulum restricting protrusion 33 determines the radial position of the pendulum 19 and restricts the movement of the pendulum 19 in the radial direction. The mass body 23 is arranged so that the inner peripheral surface of the groove 25 serving as the raceway surface does not contact the outer peripheral surface of the pin 27 in the radial direction.

  According to the fixing member 100 configured as described above, the pair of fixing members 100 has the pendulum type damping damper 200 sandwiched between both the fixing members 100 with the horizontal direction in FIG. The pendulum damping damper 200 is transported and stored. In the pendulum damping damper 200 sandwiched between the upper and lower fixing members 100, the peripheral edge portion of the through hole 13 on the radially inner side is sandwiched between the axial end surfaces of the annular clamping portions 41 of the pair of upper and lower fixing members 100.

  Further, the pin 27 of the pendulum 19 is fitted with pin restricting protrusions 31 protruding from the upper and lower fixing members 100 in the pin end surface recesses 45 on both end surfaces. Further, in the pendulum 19, the pendulum regulation protrusion 33 that protrudes from the upper and lower fixing members 100 is fitted into the positioning recess 47 of the mass body 23. Thereby, the pendulum type damping damper 200 can fix the rotor 11, the pin 27, and the pendulum 19 in the radial direction, and can reliably protect the raceway surface and the like from contact between members.

  The fixing member 100 preferably has a structure in which the pin restricting protrusion 31 and the pendulum restricting protrusion 33 are protruded from the both axial end surfaces of the disc-shaped main body 35 toward the outside in the axial direction. In the case of such a fixing member 100, the fixing member 100 having the same shape is formed by fixing the fixing member 100, the pendulum type damping damper 200, the fixing member 100, the pendulum type damping damper 200, and the fixing member 100 from the lower layer. In this order, it can be stacked in multiple stages. As a result, the fixing operation of the pendulum type damping damper 200 and component management can be easily performed, and the stacking operation can be easily automated by a robot or the like. In addition, since the fixing member 100 has the same shape as a pair of members necessary for fixing some of the pendulum damping dampers 200, the manufacturing cost of the fixing member 100 can be reduced. In addition, the work is not complicated without distinguishing the fixing members from the upper and lower sides.

  Further, the fixing members 100 of FIG. 1 can be arranged in the left-right direction as shown, and can be transported and stored with the pendulum type damping damper 200 sandwiched therebetween. In that case, the fixing members are fixed so that the fixing members 100 arranged in the axial direction do not fall off. For this fixing, for example, a clip or a band for fixing the fixing members 100 to each other can be used.

  According to the fixing member 100 of this configuration, the insertion protrusion 37 of one fixing member 100 is inserted into the through hole 13 of the rotor 11, and the insertion protrusion 37 penetrating the through hole 13 is replaced with the other fixing member. 100 insertion grooves 43 are inserted. Accordingly, the radially inner peripheral edge portion of the rotor 11 is sandwiched between the annular clamping portions 41 of the pair of fixing members 100, and the pair of fixing members 100 and the pendulum type damping damper 200 can be easily fixed coaxially. .

  In the rotor 11 fixed integrally with the pair of fixing members 100, the pin regulating protrusions 31 protruding from the fixing member 100 are fitted into the pin end surface recesses 45 of the pins 27 that are attached through the pendulum 19. Since the pin restricting protrusion 31 positions the pin 27 in the radial direction with respect to the rotor 11, the rotor 11 and the pin 27 are prevented from contacting in the radial direction due to vibration.

  In the pendulum 19 in which the mass body 23 is engaged with the pin 27 so as to be relatively movable, the pendulum regulating projection 33 protruding from the fixing member 100 is fitted into the positioning recess 47. Since the pendulum regulating projection 33 positions the pendulum 19 in the radial direction with respect to the rotor 11, the pendulum 19 and the pin 27 are prevented from contacting in the radial direction due to vibration.

  Accordingly, the rotor 11 and the pin 27, and the pin 27 and the pendulum 19 are prevented from contacting in the radial direction due to vibration. As a result, the pin 27 does not contact the inner periphery of the support hole 21 of the rotor 11. In the pendulum 19, the inner periphery of the concave groove 25 of the mass body 23 does not contact the outer periphery of the pin 27.

  Therefore, even if it receives a vibration at the time of conveyance or storage, each contact part of the rotor 11 and the pin 27 and the pin 27 and the pendulum 19 is not damaged. Thereby, shortening of the lifetime of the pendulum type damping damper 200 can be suppressed.

<Second configuration example>
Next, a second configuration example of the fixing member will be described.
FIG. 5 is an enlarged view of a main part corresponding to the B-O line cross section shown in FIG.
As in the first configuration example, the fixing member 100A can fix the pin 27 and the mass body 23 in the radial direction to protect the raceway surface of the pendulum type damping damper 200, but the shaft of the pendulum 19 and the rotor 11 can be protected. In order to prevent contact with respect to the direction, the arrangement of the rotor 11 and the fixing member 100A is set to the predetermined dimensional relationship shown below.

  When the axial distance between the pair of fixing members 100A is W, the axial thickness of the pendulum 19 is T, and the axial clearance between the rotor 11 and the mass body 23 is C, (W−T) <C is satisfied. Like that. The difference between the axial distance W between the pair of fixed members and the axial thickness T of the pendulum 19 is an axial gap d. That is, d <C. Thereby, in the fixing member 100 </ b> A, the pair of mass bodies 23 do not contact the rotor 11.

  In this fixing member 100 </ b> A, an axial gap d, which is the difference between the axial distance W between the pair of fixing members 100 and the axial thickness T of the pendulum 19, is used as the axial gap between the rotor 11 and the mass body 23. By setting it smaller than C, the axial contact between the pendulum 19 and the rotor 11 can be reliably prevented.

  Further, the fixing member 100A may be configured such that the pendulum regulating protrusion 33 protruding from one of the pair of fixing members 100A and fitted into the positioning recess 47 presses the pendulum 19 to the other of the pair of fixing members 100A. Good. In such a structure, the pin restricting protrusion 31 protruding from one side of the fixing member 100A fits into the pin end surface recess 45 and simultaneously presses the pendulum 19 to the other side of the fixing member 100A. The pendulum 19 is slightly separated from one of the fixing members 100A, and the mass body 23 contacts the other of the fixing members 100A. As a result, the pendulum 19 is prevented from axially contacting the rotor 11 and the fixing member 100A in the axial direction due to vibration.

  In the case of this configuration, (axial distance W between the pair of fixed members) − (axial thickness T of pendulum 19) <(axial gap C between rotor 11 and mass body 23) can be ensured. The axial dimension of the two surfaces, that is, the axial end surface of one of the disk-shaped main bodies 35 and the axial end surface of the annular clamping portion 41, that is, the dimension H is manufactured particularly precisely.

<Third configuration example>
Next, a third configuration example of the fixing member will be described.
FIG. 6 is an enlarged view of a main part corresponding to the cross section taken along the line C-O in FIG.
The fixing member 100B of this configuration regulates the pendulum 19 in the axial direction in addition to the configuration of the fixing member 100A of the second configuration example described above. That is, the pendulum restricting projection is set so that the axial distance W between the pair of fixing members 100B is set larger than the axial thickness T of the pendulum 19 and the pendulum 19 is positioned at the center of the pair of fixing members 100B. 33 is inserted into the positioning recess 47.

  In the fixing member 100B, the pendulum 19 is pressed from both axial sides of the pair of fixing members 100B. In this case, the pendulum 19 is provided with a slight gap between the pair of fixing members 100B and the side surface in the pendulum thickness direction. That is, the axial distance W between the pair of fixing members 100 </ b> B is set larger than the axial thickness T of the pendulum 19, and the pendulum 19 is positioned at the center of the pair of fixing members 100. For example, if the difference between the axial distance W between the pair of fixing members 100B and the axial thickness T of the pendulum 19 is d, the pendulum 19 has an axial gap d / b between the pair of fixing members 100B. 2 are equally distributed in the axial direction. In such a configuration, the positioning recess 47 is formed such that the bottoms of the recesses are formed to have the same depth, and the tip of the pendulum restricting projection 33 fitted from both sides in the axial direction of the pendulum 19 is abutted against the recess bottom of the positioning recess 47. realizable.

  According to this configuration, in addition to restricting the pin 27 of the second configuration example in the radial direction and the axial direction, the pendulum 19 can also be regulated in the radial direction and the axial direction, and the pendulum 19 and the fixing member 100B can be controlled. Contact (rattle) in the axial direction with the disc-shaped main body 35 can be prevented.

As described above, according to the fixing members 100, 100A, and 100B of this configuration, the rotor 11, the pin 27, and the pendulum 19 of the pendulum type damping damper 200 are reliably positioned in the radial direction of the rotor 11, Further, the fixing members 100A and 100B are also positioned in the axial direction.
Therefore, even if vibration is applied to the pendulum type damping damper 200 during transportation or storage, the rotor 11 and the pin 27, and the pin 27 and the pendulum 19 are not in contact with each other, and the occurrence of damage can be reliably prevented. As a result, the pendulum damping damper 200 does not cause damage such as indentation at the contact portion (the raceway surface or the like) that comes into contact with the operation during use, and can suppress the shortening of the life.

  The present invention is not limited to the above-described embodiments, and the configurations of the embodiments may be combined with each other, or may be modified or applied by those skilled in the art based on the description of the specification and well-known techniques. The invention is intended and is within the scope of seeking protection.

For example, in the above configuration example, the insertion protrusion 37 in the boss portion 40 of the fixing member is extended only to one side in the axial direction, but not limited to this, the thickness of the rotor 11 is taken into consideration. You may provide in the axial direction both sides of a member.
Further, the pin restricting protrusion 31 and the pendulum restricting protrusion 33 may be inserted into each recessed portion with a slight gap in addition to the configuration of being fitted into the pin end surface recessed portion 45 and the positioning recessed portion 47.
Further, in addition to the pin restricting protrusion 31 and the pendulum restricting protrusion 33 being provided on the disc-shaped main body 35, the fixing member includes a pin restricting protrusion 31 and a body member having another planar shape such as a cross shape or a star shape. A configuration in which the pendulum regulating protrusion 33 is formed may be used. In that case, the material cost can be reduced as compared with the disk-shaped main body 35.

As described above, the following items are disclosed in this specification.
(1) A plurality of pendulums are provided on the outer peripheral edge of a disc-shaped rotor having a through hole coaxial with the rotation center, and are supported so as to reciprocate in the circumferential direction of the rotor. A plurality of support holes for supporting each of the pendulums, wherein the pendulum is disposed to face the outer side in the axial direction of the rotor, with a pin penetrating through the support hole with play. A pendulum type vibration damping damper having a concave groove engaged with play at an end in a direction and a pair of mass bodies formed with at least two positioning depressions, both axial sides of the pendulum type vibration damper And a fixing member for a pendulum type damping damper that fixes the pendulum to the rotor,
The fixing member is
An insertion protrusion that protrudes outward in the axial direction at a corresponding position of the through hole of the rotor and engages with the through hole;
A plurality of pin restricting protrusions protruding outward in the axial direction at corresponding positions of the plurality of pins, and engaging with axial ends of the pins;
A plurality of pendulum restricting protrusions that protrude outward in the axial direction at positions corresponding to the positioning recesses of the mass body and engage with the positioning recesses;
A member for fixing a pendulum type damping damper.
According to the fixing member of the pendulum type damping damper, the insertion protrusion of one fixing member is inserted into the through hole of the rotor, and the insertion protrusion passing through the through hole is inserted into the insertion groove of the other fixing member. By doing so, the peripheral part of the inner peripheral side of the rotor can be fixed by being sandwiched between the pair of fixing members. In the rotor fixed integrally with the pair of fixing members, pin restricting protrusions protruding from the fixing members are fitted into the pin end surface recesses of the pins having the pendulum attached to the outer peripheral edge. The pin is positioned in the radial direction with respect to the rotor by inserting the pin regulation protrusion of the rotor into the pin end surface recess. Further, the pendulum is fitted with a pendulum restricting protrusion protruding from the fixing member in the positioning recess. The pendulum is positioned in the radial direction with respect to the rotor by inserting the pendulum restricting protrusion of the rotor into the positioning recess. Accordingly, the rotor and the pin, and the pin and the pendulum are prevented from contacting in the radial direction due to vibration.

(2) The axial distance between the pair of fixing members sandwiching the pendulum type damping damper in the axial direction is W, the axial thickness of the pendulum is T, and the axial clearance between the rotor and the mass body is The member for fixing the pendulum type damping damper according to (1), wherein C is (WT) <C when C is satisfied.
According to the fixing member of the pendulum type damping damper, the axial gap d, which is the difference between the axial distance W between the pair of fixing members and the axial thickness T of the pendulum, is set in the axial direction between the rotor and the mass body. By setting the clearance smaller than the gap C, the axial contact between the pendulum and the rotor can be prevented.

(3) The axial distance between the pair of fixing members is greater than the axial thickness of the pendulum,
The positioning recess of the pair of mass bodies is a member for fixing a pendulum type damping damper according to (2), wherein the bottoms of the recesses against which the tips of the pendulum restricting protrusions are abutted are formed at the same depth.
According to the fixing member of the pendulum type damping damper, the pendulum is pressed from both of the pair of fixing members. In this case, the pendulum is provided with a slight gap between both the fixing members and the axial side surface of the pendulum. That is, the distance between the pair of fixing members is set larger than the axial thickness of the pendulum, and the pendulum is positioned at the center in the axial direction of the pair of fixing members. Such a configuration can be realized by, for example, abutting the pendulum regulating protrusions inserted from both of the pair of pendulums against the bottom of the positioning recess of the mass body. In this configuration, the pendulum can prevent contact with the rotor and the fixed member in the axial direction due to vibration.

(4) The pendulum damping damper in which the rotor, the pin, and the pendulum are positioned by the fixing member for the pendulum damping damper according to any one of (1) to (3).
According to this pendulum type damping damper, the relative position of the rotor, the pin, and the pendulum is positioned at least in the radial direction of the rotor by fixing the pendulum type damping damper by the fixing member. Thereby, even if a vibration is added at the time of conveyance or storage, the rotor and the pin, and the pin and the pendulum do not contact each other. As a result, the pendulum damping damper is not damaged such as indentation at the contact portion that comes into contact with the operation during use.
