Description

  The present invention relates to parking in a vehicle for connecting each brake device for the left and right rear wheels to a parking brake operation unit so that the operation force to the brake operation unit is evenly transmitted to each brake device. The present invention relates to a brake device.

  Conventionally, there is a parking brake device disclosed in Patent Document 1 below. According to this publication, the parking brake device is arranged between each brake device for the left and right rear wheels and the brake operation unit for parking in the longitudinal direction of the vehicle body, and an equalizer main body extending in the width direction of the vehicle body. Left and right brake cables (inner cables) that extend forward from the respective brake devices and whose extended ends are locked to the respective longitudinal ends of the equalizer main body, and the brake operation unit An operation cable (inner cable) extending rearward and an axial center extend in the vertical direction, and are attached to an extended end portion of the operation cable, and are locked to a longitudinal center portion of the equalizer main body. And a locking pin.

  In addition, the parking brake device includes an outer tube (outer cable) that fits inside each cable in the longitudinal direction so as to be slidable in the longitudinal direction, and each end of the outer tube in the longitudinal direction. And a fixture for fixing the part to the vehicle body. The brake cables and the operation cables are pulled toward the brake devices by the biasing force of the springs in the brake devices. When the parking brake device is not operated such as when the vehicle is running, the brake cables and the operation cables are given a slight tensile force by the biasing force, and the outer tubes are Inside, it is supposed that slack does not arise in the middle part of each cable in the longitudinal direction.

  And when it is going to park a vehicle, a passenger | crew gives operating force to the said brake operation part against the urging | biasing of the spring of each said brake device, and pulls the said operation cable ahead. Then, the operating force is equally transmitted to the brake devices by the equalizer main body and the locking structure of the cables to the respective parts of the equalizer main body, so that each of the brake devices performs a proper braking operation. It is done. As a result, a desired parking state is obtained in the vehicle.

  The assembly work of the parking brake device is usually performed as follows.

  That is, first, as a first operation, a locking pin attached to the extended end portion of the operation cable is locked to the central portion of the equalizer main body.

  Next, as a second operation, the equalizer body is rotated about the axis of the locking pin, and one end portion of the equalizer body in the longitudinal direction is connected to one end portion of the equalizer body of the left and right brake cables. The brake cable is brought close to the extended end of one of the brake cables.

  In this way, if one end portion of the equalizer body and the extending end portion of the one brake cable are brought close to each other, the extension of the one brake cable can be performed without receiving a biasing force from the brake device. The extending end can be locked to one end of the equalizer body by bending the end, and this locking operation is achieved.

  Next, as a third operation, the equalizer main body is rotated in the opposite direction opposite to the rotation, and the other end portion of the equalizer main body is brought close to the extending end portion of the other brake cable. In this case, during the reverse rotation of the equalizer main body, the urging force from the brake device starts to be applied to the one brake cable. For this reason, thereafter, an external force is applied to the equalizer body so as to apply a tensile force to the one brake cable against the biasing force, and the equalizer body is further rotated in the reverse direction. As a result, the other end portion of the equalizer body and the extended end portion of the other brake cable are brought close to each other.

  If the other end portion of the equalizer main body and the extension end portion of the other brake cable are brought close to each other in this way, the extension of the other brake cable can be performed without receiving a biasing force from the brake device. The extending end can be locked to the other end of the equalizer body by bending the end, and this locking operation is achieved.

  Next, as a fourth operation, the equalizer body is rotated by the urging force from each brake device. Then, the assembly work of the parking brake device is completed.

JP 2000-185642 A

  By the way, in the assembly work of the parking brake device, the equalizer main body is rotated (including reverse rotation) around the axis of the locking pin. When the equalizer main body is rotated to some extent, the equalizer main body is Abutting on the extended end of the operation cable, further rotation is restricted. For this reason, there is a limit even if one end and the other end of the equalizer main body are sufficiently brought close to the extended end portions of the operation cables by largely rotating the equalizer main body.

  Therefore, in this case, an external force is applied to the extension end so as to pull the extension end of the brake cable forward while resisting the urging force from the brake device. The extension end of the operation cable is locked to one end or the other end of the equalizer main body by bending it in a state of being sufficiently close to the equalizer main body. The locking operation of performing the above locking while applying an external force is complicated.

  In particular, in the third operation, as described above, an external force is applied to the equalizer body so as to apply a tensile force to one brake cable, and in this state, the other brake cable is connected to the other end portion of the equalizer body. Although the extending end is locked, the locking operation of locking the above while applying an external force to the equalizer main body is also very complicated.

  Therefore, the assembly work of the parking brake device shown as the above-described conventional technique may be complicated.

  The present invention has been made paying attention to the above-described circumstances, and an object of the present invention is to facilitate the assembly work of a parking brake device in a vehicle.

According to the first aspect of the present invention, there is provided an equalizer main body 12 which is disposed between the brake devices 7 for the left and right rear wheels 3 and 3 and the brake operation unit 8 for parking in the front-rear direction of the vehicle body 2 and extends in a certain direction. Left and right brake cables 13, 13 extending forward from the respective brake devices 7, each extended end portion 13 a being locked to each longitudinal end portion of the equalizer body 12, and the brake operation The operation cable 17 extending rearward from the portion 8 and the shaft center 18 extend in the one direction and in a direction orthogonal to the extension end portion 17a of the operation cable 17, respectively. In a parking brake device in a vehicle provided with a locking pin 19 which is attached to 17a and locked to the central portion in the longitudinal direction of the equalizer body 12,
The equalizer body 12 is formed with a slit 33 extending in the longitudinal direction and penetrating in the extending direction of the extending end portion 17 a of the operation cable 17, and together with the locking pin 19 along the longitudinal direction of the slit 33. The extension end 17a of the operation cable 17 is passed through the slit 33 so that the extension end 17a of the operation cable 17 can be moved, and each end of the locking pin 19 is detachably locked. The parking brake device for a vehicle is characterized in that a locking recess 34 is formed on the back surface of the central portion of the equalizer body 12 so as to straddle the slit 33.

  In addition, in this section, the reference numerals and drawing numbers appended to the above terms are not intended to limit the technical scope of the present invention to the “Example” section and the contents of the drawings described later.

  The effects of the present invention are as follows.

According to a first aspect of the present invention, there is provided an equalizer main body that is disposed between each brake device for left and right rear wheels and a brake operation unit for parking in the front-rear direction of the vehicle body, and extends in one direction. Left and right brake cables that extend forward, each extending end of which is locked to each longitudinal end of the equalizer body, and an operation cable that extends rearward from the brake operation unit, The shaft center extends in the one direction and in a direction orthogonal to the extending end of the operation cable, is attached to the extending end of the operation cable, and is locked to the longitudinal center of the equalizer body. In a parking brake device in a vehicle provided with a locking pin,
A slit extending in the longitudinal direction of the equalizer main body and penetrating in the extending direction of the extending end portion of the operation cable is formed in the equalizer body, and the operation cable extends along with the locking pin along the longitudinal direction of the slit. The extension end portion of the operation cable passes through the slit so that the end portion can be moved, and a locking recess for removably locking each end portion of the locking pin is provided at the back of the central portion of the equalizer body. Are formed so as to straddle the slit.

  For this reason, the assembly work of the parking brake device can be performed as follows.

  That is, first, as a first operation, an assembly including the equalizer main body, an operation cable having an extending end portion penetrated through a slit of the equalizer main body, and a locking pin attached to the extending end portion of the operation cable. Form.

  Next, as a second operation, the equalizer body is displaced in one longitudinal direction to separate the locking pin and the locking recess from each other, and the equalizer body is moved around the axis of the locking pin. The one end portion on the one-direction side of the equalizer body is made to approach the extension end portion of the one brake cable on the one-direction side among the extension end portions of the left and right brake cables.

  If the end portion of the equalizer body and the extending end portion of the one brake cable are brought close to each other in this way, the extending end of the one brake cable is not subjected to the urging force from the brake device. The extending end portion can be locked to one end portion of the equalizer main body by bending the portion, and this locking operation is achieved.

  In the above case, since the locking pin and the locking recess are separated from each other and the equalizer body is rotated, the shaft center of the locking pin is temporarily locked in the locking recess. The one end of the equalizer main body and the extending end of the one brake cable can be brought closer to each other than rotating the equalizer main body around the center.

  Moreover, when the equalizer main body is rotated, the extension end of the operation cable is located in the slit and contact between the extension end and the equalizer main body is avoided. A large rotation is possible without being restricted by the extended end of the operation cable.

  For this reason, the one end part of the equalizer main body and the extending end part of the one brake cable can be made to approach each other more sufficiently. Therefore, the one end part of the equalizer body and the extension end part of the one brake cable are made closer to each other, and the extension end part of the one brake cable is opposed to the urging force from the brake device. The operation of pulling the cable toward the equalizer main body 12 is unnecessary or only a little.

  Further, as described above, since the equalizer main body can be largely rotated, in order to achieve the above locking, one end portion of the equalizer main body and the extended end portion of one brake cable are brought into a desired relative posture. It is possible to improve the degree of freedom at the time of making it, and the workability of the locking is improved.

  As a result, the locking operation of the extended end portion of the one brake cable with respect to the one end portion of the equalizer main body can be performed more easily.

  Next, as a third operation, the equalizer body is displaced in the other direction in the longitudinal direction to disengage the locking pin and the locking recess from each other, and the equalizer body is moved around the axis of the locking pin. The other end portion on the other direction side of the equalizer body is made to approach the extension end portion of the other brake cable on the other direction side.

  If the other end portion of the equalizer main body and the extension end portion of the other brake cable are brought close to each other in this way, the extension of the other brake cable can be performed without receiving a biasing force from the brake device. The extending end can be locked to the other end of the equalizer body by bending the end, and this locking operation is achieved.

  In the above case, since the locking pin and the locking recess are separated from each other and the equalizer main body is rotated in the reverse direction, the locking pin is temporarily locked to the locking recess and is attached to one end of the equalizer main body. Compared to rotating the equalizer body around the axis of the locking pin in a state where the extended end of the one brake cable is locked, the other end of the equalizer body The extension end of the other brake cable can be brought closer to each other.

  In addition, when the equalizer body is rotated in the reverse direction, the extension end of the operation cable is located in the slit, and contact between the extension end and the equalizer body is avoided. A large reverse rotation is possible without being restricted by the extended end of the operation cable.

  For this reason, the other end part of the equalizer main body and the extended end part of the other brake cable can be made to approach each other more sufficiently. Therefore, the other end of the equalizer main body and the extension end of the other brake cable are made closer to each other, and the extension end of the other brake cable is opposed to the urging force from the brake device. The operation of pulling the portion toward the equalizer main body 12 is unnecessary or only a little.

  Further, as described above, since the equalizer main body can be largely rotated in the reverse direction, in order to achieve the above-described locking, the other end of the equalizer main body and the extension end of the other brake cable are connected to each other in a desired relative direction. The degree of freedom in making the posture can be improved, and the workability of the locking is improved.

  As a result, the locking operation of the extended end portion of the other brake cable with respect to the other end portion of the equalizer body can be facilitated.

  Next, as a fourth operation, the locking pin and the locking recess are locked to each other, and the equalizer body is rotated by a biasing force from each brake device. Then, the assembly work of the parking brake device is completed.

  And, as described above, in the assembly work of the parking brake device, the locking operation of the extended end portion of each brake cable to the one end portion and the other end portion of the equalizer main body can be performed more easily, respectively. The assembly work of the parking brake device can be easily performed.

  Left and right front wheels (not shown) and left and right rear wheels 3 and 3 are suspended from the vehicle body 2 of the vehicle 1. The vehicle 1 includes a parking brake device 4 that can hold the vehicle 1 in a braking state by an operation of a passenger during parking. The parking brake device 4 is pivotally supported by a brake device 7 that can individually brake each of the rear wheels 3 and the front portion of the vehicle body 2, and can be operated by inputting an operation force by an occupant during parking. A manual lever type brake operation unit 8 and an equalizer mechanism 9 for interlockingly connecting the brake devices 7 to the brake operation unit 8 are provided.

  The equalizer mechanism 9 is arranged between the brake devices 7 of the left and right rear wheels 3 and 3 and the brake operation unit 8 in the front-rear direction of the vehicle body 2, and is in a certain “one direction” width direction of the vehicle body 2. The extending equalizer body 12, the left and right brake cables 13, 13 extending while being bent forward from the respective brake devices 7, and the respective axial centers 14 are “one-way” and the extending ends of the brake cables 13. Left and right that extend in the vertical direction perpendicular to each of the portions 13a, are attached to the extended end portions 13a of the brake cables 13 at their axial center portions, and are locked to the end portions in the longitudinal direction of the equalizer body 12. Locking pins 15 and 15 are provided.

  The equalizer mechanism 9 includes an operation cable 17 that extends while bending backward from the brake operation unit 8, and an axial center 18 that extends in the “one direction” and the extended end portion 17 a of the operation cable 17. A locking pin 19 that extends in the vertical direction perpendicular to each other, and whose axial center portion is attached to the extending end portion 17a of the operation cable 17 and is locked to the longitudinal center portion of the equalizer body 12, The outer tubes 20 that are fitted in the middle portions of the cables 13 and 17 in the longitudinal direction so as to be slidable in the longitudinal direction, and the end portions of the outer tubes 20 in the longitudinal direction are fixed to the vehicle body 2. And a fixture 21 which is a fastener.

  The brake cables 13 and the operation cables 17 are pulled toward the brake devices 7 by the spring biasing force F1 of the brake devices 7. In a non-use state where the parking brake device 4 is not operated, such as when the vehicle 1 is traveling, a slight tensile force is applied to the brake cables 13 and the operation cables 17 by the biasing force F1. In each of the outer tubes 20, no slack is generated in the midway portion in the longitudinal direction of each of the cables 13 and 17.

  The equalizer body 12 is made of sheet metal and has a square pipe shape. The equalizer body 12 extends in the width direction of the vehicle body 2 and faces away from each other in the front-rear direction, and is separated from the rear plates 23 and 24 in the vertical direction. The upper and lower plates 23 and 24 have upper and lower edges 25 and 26 which are integrally coupled to each other.

  Upper and lower ends of the upper and lower plates 25 and 26 are respectively formed with upper and lower locking holes 29 and 30 for allowing the upper and lower ends of the locking pin 15 to be fitted from the axial direction. ing. Further, each end of the upper plate 25 extends outward and rearward from the upper locking hole 29 to the end edge of the upper plate 25, and an extended end 13 a of the brake cable 13. A slit 31 is formed to allow the passage in the vertical direction. In addition, a notch 32 is formed at the center in the vertical direction of each end of the rear plate 24 so as to extend in the longitudinal direction and allow the extended end 13a of each brake cable 13 to be inserted therethrough.

  A slit 33 extending in the longitudinal direction and penetrating in the front-rear direction, which is the extending direction of the extending end portion 17 a of the operation cable 17, is formed in the central portion of the front plate 23 in the vertical direction. The extension end 17a of the operation cable 17 is passed through the slit 33 so that the extension end 17a of the operation cable 17 can be moved along with the locking pin 19 along the longitudinal direction of the slit 33. ing. Further, a locking recess 34 for detachably locking each end of the locking pin 19 in the axial direction is provided on the rear surface of the front plate 23 of the equalizer body 12 (the front plate as viewed from the brake operation unit 8 side). 23) is bent so as to straddle the slit 33. The locking recess 34 is formed in a triangular top shape in plan view.

  When the vehicle 1 is to be parked, the occupant applies an operating force F2 to the brake operating portion 8 against the urging force F1 of the spring of each brake device 7, and the operating cable 17 is moved forward. Pull. Then, the operating force F2 is evenly transmitted to the brake devices 7 via the equalizer mechanism 9 including the equalizer main body 12 and the locking structures of the cables 13 and 17 to the respective parts of the equalizer main body 12. These brake devices 7 are appropriately braked. As a result, a desired parking state is obtained in the vehicle 1.

  The assembly work of the parking brake device 4 will be described.

  First, as a first operation, as shown in FIG. 4, the equalizer body 12 is moved forward so that the extended end portion 17 a of the operation cable 17 penetrates the slit 33 from the front. Next, the locking pin 19 and the sleeve 37 are sequentially fitted to the extending end portion 17a penetrated in this way (one-dot chain line in FIG. 4), and the sleeve 37 is caulked with a tool, The locking pin 19 is attached to the extended end portion 17a. Thereby, the assembly by the said equalizer main body 12, the operation cable 17, and the latching pin 19 is formed.

  Next, as a second operation, as shown in FIG. 5, the equalizer body 12 is displaced in one longitudinal direction (right direction) to separate the locking pin 19 and the locking recess 34 from each other. The equalizer body 12 is rotated A about the axis 18 of the locking pin 19, and the one end (a right side) end portion 12 a of the equalizer body 12 is connected to each of the left and right brake cables 13, 13. Of the extended end portions 13a and 13a, the extended end portion 13a of one brake cable 13 on the one direction (right direction) side is made to approach.

  If the one end portion 12a of the equalizer body 12 and the locking pin 15 of the extending end portion 13a of the one brake cable 13 are brought close to each other in this way, the biasing force F1 from the brake device 7 is received. The extension end portion 13a of the one brake cable 13 can be bent without being bent, and the extension end portion 13a can be locked to the one end portion 12a of the equalizer body 12. Achieved.

  The locking operation of the locking pin 15 to the one end portion 12a of the equalizer body 12 is well known. First, as shown by a one-dot chain line in FIG. 2, the locking operation is performed above the one end portion 12a of the equalizer body 12. The pin 15 is positioned. Next, the locking pin 15 is moved downward so that the locking pin 15 is sequentially locked in the upper and lower locking holes 29 and 30, and the extended end portion 13a of the brake cable 13 is connected to the slit. The slit 31 is bent downward so as to be parallel to the slit 31 and passed through the slit 31 downward. Next, when the equalizer main body 12 is rotated in the opposite direction opposite to the rotation A and the extended end portion 13a of the one brake cable 13 is fitted into the notch 32, the locking operation is performed. finish.

  In the above case, as shown in FIG. 5, since the locking pin 19 and the locking recess 34 are separated from each other and the equalizer body 12 is rotated A, the locking pin 19 is temporarily placed in the locking recess 34. Compared to rotating the equalizer body 12 around the axis 18 of the locking pin 19 in the locked state, the one end portion 12a of the equalizer body 12 and the one brake cable 13 are The extended end portion 13a can be made closer to each other.

  In addition, when the equalizer main body 12 is rotated A, the extended end portion 17a of the operation cable 17 is located in the slit 33, and the contact between the extended end portion 17a and the equalizer main body 12 is avoided. Therefore, the equalizer main body 12 can be largely rotated A without being restricted by the extended end portion 17 a of the operation cable 17.

  For this reason, the one end part 12a of the equalizer main body 12 and the extended end part 13a of the one brake cable 13 can be made to approach each other more sufficiently. Therefore, while trying to make the one end portion 12a of the equalizer main body 12 and the extended end portion 13a of the one brake cable 13 closer to each other, the one brake is applied against the urging force F1 from the brake device 7. The operation of pulling the extended end portion 13a of the cable 13 toward the front which is the equalizer main body 12 side is unnecessary or only a little.

  Further, as described above, since the equalizer main body 12 can be largely rotated A, one end portion 12a of the equalizer main body 12 and the extended end portion 13a of one brake cable 13 can be used to achieve the above-described locking. Can be improved in the desired relative posture, and the locking workability is improved.

  Specifically, due to the large rotation A of the equalizer main body 12, the slit 31 formed in the other end 12b of the equalizer main body 12 and the extended end 13a of the one brake cable 13 are more parallel to each other. If the end portion 12a of the equalizer body 12 and the extended end portion 13a of the one brake cable 13 are in a desired relative posture, the amount of bending of the extended end portion 13a of the one brake cable 13 is reduced. The extension end portion 13a can be easily passed through the slit 31 by being suppressed, and the workability of the locking is improved.

  As a result, the locking operation of the extended end portion 13a of the one brake cable 13 with respect to the one end portion 12a of the equalizer body 12 can be facilitated.

  Next, as a third operation, as shown in FIG. 6, the equalizer body 12 is displaced in the other direction (left direction) in the longitudinal direction to separate the locking pin 19 and the locking recess 34 from each other. The equalizer body 12 is rotated in the reverse direction B opposite to the rotation A around the axis 18 of the locking pin 19, and the other end portion 12b on the other direction (left direction) side of the equalizer body 12 is moved. The other end (the left direction) of the other brake cable 13 on the other side is made to approach the extended end 13a.

  If the other end portion 12b of the equalizer main body 12 and the locking pin 15 of the extended end portion 13a of the other brake cable 13 are brought close to each other in this way, the urging force F1 from the brake device 7 is generated. The extended end 13a of the other brake cable 13 can be bent without being received, and the extended end 13a can be locked to the other end 12b of the equalizer main body 12. Work is accomplished. The specific contents of this locking operation are the same as described above.

  In the above case, as shown in FIG. 6, the locking pin 19 and the locking recess 34 are separated from each other and the equalizer body 12 is reversely rotated B. Therefore, as shown in FIG. The locking pin 19 is locked in the locking recess 34 and the extension end 13a of the one brake cable 13 is locked in the one end 12a of the equalizer body 12. Compared to the reverse rotation B of the equalizer main body 12 about the axis 18 of the nineteen, the other end 12b of the equalizer main body 12 and the extended end 13a of the other brake cable 13 are You can get closer.

  In addition, when the equalizer main body 12 is rotated in the reverse direction B, the extended end portion 17a of the operation cable 17 is located in the slit 33, and contact between the extended end portion 17a and the equalizer main body 12 is avoided. Therefore, the equalizer main body 12 can be largely reversely rotated B without being restricted by the extended end portion 17 a of the operation cable 17.

  For this reason, the other end portion 12b of the equalizer main body 12 and the extended end portion 13a of the other brake cable 13 can be brought closer to each other. Therefore, the other end portion 12b of the equalizer main body 12 and the extended end portion 13a of the other brake cable 13 are made closer to each other while opposing the urging force F1 from the brake device 7, The operation of pulling the extended end portion 13a of the brake cable 13 toward the front which is the equalizer main body 12 side is unnecessary or only a little.

  Further, as described above, the equalizer main body 12 can be largely rotated in the reverse direction B, so that the other end portion 12b of the equalizer main body 12 and the extended end portion of the other brake cable 13 are achieved in order to achieve the above locking. It is possible to improve the degree of freedom when bringing 13a into a desired relative posture, and the workability of the locking is improved.

  Specifically, due to the large reverse rotation B of the equalizer main body 12, the slit 31 formed in the other end 12b of the equalizer main body 12 and the extended end 13a of the other brake cable 13 are more If the other end portion 12b of the equalizer body 12 and the extended end portion 13a of the other brake cable 13 are set in a desired relative posture so as to be parallel, the amount of bending of the extended end portion 13a of the other brake cable 13 is set. The extension end portion 13a can be easily passed through the slit 31 and the workability of the locking is improved.

  As a result, the locking operation of the extended end portion 13a of the other brake cable 13 with respect to the other end portion 12b of the equalizer body 12 can be facilitated.

  Next, as a fourth operation, as shown in FIG. 1, the locking pin 19 and the locking recess 34 are locked to each other, and the equalizer body 12 is moved by the urging force F <b> 1 from each brake device 7. Rotate to get the posture. Then, the assembly work of the parking brake device 4 is completed.

  And as mentioned above, in the assembly work of the parking brake device 4, the locking work of the extended end portions 13a of the brake cables 13 to the one end portion 12a and the other end portion 12b of the equalizer main body 12, respectively, Since it can be performed more easily, the assembly work of the parking brake device 4 can be easily performed.

  7A and 7B show another embodiment of the locking recess 34. FIG.

  7A, the locking recess 34 has a semicircular shape into which the locking pin 19 is closely fitted in a plan view.

  According to FIG. 7B, a pair of left and right projections 39, 39 are formed on the rear surface of the front plate 23 of the equalizer main body 12, and a locking recess 34 is formed between both the projections 39, 39.

  Although the above is based on the illustrated example, the brake operation unit 8 may be a pullable stick type or a pedal type that can be stepped on. The “one direction” in which the equalizer body 12 extends may be the front-rear direction or the vertical direction of the vehicle body 2. The equalizer body 12 may be formed using a square pipe as a material, but may be formed by bending a plate material into a square pipe shape.

  Further, the rear plate 24 of the equalizer main body 12 may be omitted, that is, the side cross section of the equalizer main body 12 may be formed in a U shape that opens rearward. In this case, in the equalizer body 12, the upper plate 25 and the lower plate 26 in which the upper and lower locking holes 29 and 30 are formed are brought close to each other, and the distance between the two portions is set to the brake size. You may make it slightly larger than the diameter of the extension end part 13a of the cable 13. FIG. According to this, since the extended end portion 13a of the brake cable 13 is sandwiched between the two portions, the locked state of the locking pin 15 in the upper and lower locking holes 29, 30 is maintained. Is done.

  Further, the slits 31 formed at each end portion of the upper plate 25 of the equalizer main body 12 may be formed to extend outward in a direction perpendicular to the center line in the width direction of the vehicle body 2. The left and right cutouts 32, 32 may be slits that are continuous with each other. Further, the first work in the assembly work of the parking brake device 4 and the other second to fourth work do not need to be performed continuously, and may be performed in separate work processes.
