Protrusively toward.

  Here, since the split push rod 102 connected to the clutch master cylinder 62 is reduced in length than the push rod 105, the split push rod 102 is easily directed from the through hole of the mounting plate 115 toward the passenger compartment CR. The clutch master cylinder 62 can be easily mounted in the engine compartment ER.

  In particular, in a left-hand drive vehicle, a brake booster and a suspension tower are provided in the vicinity of the area where the clutch master cylinder 62 is disposed, and the work space is limited. It is possible to effectively reduce the burden on the assembler due to the reduction of.

  FIG. 11 is a perspective view when the elastic member 101 is disposed between the divided push rod 103 and the divided push rod 102 and the divided push rod 103 and the divided push rod 102 are coupled by the connecting member 104. FIG. 12 is a side view of FIG.

  As shown in FIGS. 11 and 12, the connection member 104 is inserted into the through hole 102 a of the split push rod 102.

  At this time, the operating portion 132 is operated to move the protruding portion 133 of the connecting member 104 along the groove portion 140 formed in the split push rod 102. Here, the operation part 132 is movable along the groove part 120 formed in the split push rod 103. The shape of the groove 120 corresponds to the groove 140, and the protrusion 133 is moved to the fourth groove 143 by moving the operation part 132 in the order of the third groove 127, the second groove 126, and the first groove 125. The fifth groove 142 and the sixth groove 141 are moved in this order.

  In this way, the divided push rod 102 and the divided push rod 103 are connected. Here, the protrusion 133 enters the groove 141 extending in the axial direction, so that the divided push rod 102 and the divided push rod 103 are connected to each other so as to be relatively movable in the axial direction.

  As described above, in the push rod 105 according to the present embodiment, the split push rod 102 and the split push rod 103 can be easily connected, and the assemblability of the operation mechanism 200 can be improved. . In particular, it is not necessary to use a fastening member such as a bolt, and the work burden is reduced.

  Here, the end of the split push rod 102 and the end of the split push rod 103 are separated from each other, and the elastic member 101 is positioned therebetween. One end portion of the elastic member 101 is connected to the reduced diameter portion 129 of the split push rod 103, and the other end portion can be separated from and contacted with the end face of the split push rod 102.

  For this reason, even if the vibration of the engine shown in FIG. 2 is transmitted to the split push rod 102, the elastic member 101 can suppress the transmission from the split push rod 102 to the split push rod 103.

  Thereby, it can suppress that a vibration is transmitted to the pedal 60B shown in FIG. 2, can suppress that the pedal 60B vibrates, and the operativity at the time of an operator operating the pedal 60B can be suppressed. Can be improved.

  Furthermore, the outer peripheral surface of the elastic member 101 and the outer peripheral surfaces of the split push rods 102 and 103 are substantially coincident with each other, and the volume of the elastic member 101 is suppressed to be small, and the push rod 105 itself can be made compact. ing. The elastic member 101 may be a rubber member formed in a cylindrical shape, and may be a spring or the like.

  FIG. 13 is a perspective view of the push rod 105 in a state where the operator does not depress the pedal 60B.

  Here, in FIG. 2, since the elastic member 64 biases the connecting member 60A toward the driver's compartment, the split push rod 103 shown in FIG. 13 is also biased toward the driver's seat. For this reason, the split push rod 103 is urged toward the cab side, the projection 133 of the connecting member 104 moves through the sixth groove 141 to the handle compartment, and the end face of the elastic member 101 and the end face of the split push rod 102 are moved. They are spaced apart from each other, and a gap is formed between the divided push rod 102 and the elastic member 101.

  Further, the projection 133 of the connection member 104 is also located at the end of the sixth groove 141 on the divided push rod 103 side. When the operator depresses the pedal 60B, the elastic member 101 is displaced toward the split push rod 102, and the protrusion 133 of the connection member 104 also moves the inside of the sixth groove 141 toward the engine compartment ER. Displace towards.

  For this reason, when the driver steps on the pedal 60B, first, the elastic member 101 and the split push rod 102 come close to each other, and so-called play is provided.

  That is, as described above, the connection member 104 connects the split push rod 103 and the split push rod 102 so as to be relatively movable in the axial direction, so that a so-called play function can be imparted to the operation mechanism 200. .

  Here, since the extending direction of the sixth groove 141 in which the protrusion 133 slides and the extending direction of the fifth groove 142 are mutually intersecting directions, the push rod 105 is displaced in the axial direction. In the process, the protrusion 133 can be prevented from entering the fifth groove 142.

  That is, when the driver removes his / her foot from the pedal 60 </ b> B, the protrusion 133 is locked to the end on the divided push rod 103 side of the inner surface of the divided push rod 102 that defines the sixth groove 141. Thereby, the connection state of the division | segmentation push rod 102 and the connection member 104 is maintained.

  In the groove 120, when the push rod 105 moves in the axial direction, the extending direction of the first groove 125 where the operation part 132 is located and the extending direction of the second groove 126 extend so as to intersect with each other. Therefore, the operation part 132 is suppressed from entering the second groove part 126. Here, when the driver removes his / her foot from the pedal 60 </ b> B, the operation portion 132 is locked to the elastic member 101, whereby the connection state between the connection member 104 and the split pushrod 103 is maintained.

  In the present embodiment, the connecting member 104 as described above is not an essential configuration. For example, the split push rod 102 and the split push rod 102 are separated in a state where the split push rod 102 and the split push rod 103 are separated from each other. An elastic member connected to the rod 103 may be provided. Even if the push rod is configured in this way, it is possible to suppress the vibration from the engine or the like from being transmitted to the pedal 60B by the elastic member.

  Although FIGS. 1 to 13 illustrate the case where the present invention is applied to the operation mechanism 200 that transmits the operator's power to the clutch mechanism, the present invention is not limited thereto. FIG. 14 is a schematic diagram illustrating an example in which the brake mechanism 2 is applied to an operation mechanism 300 that transmits power from a driver.

  As shown in FIG. 14, the operation mechanism 300 includes a brake pedal 10 a, a connection member 10 connected to the brake pedal 10 a and rotatably connected to the board 90, and the connection member 10 via the clevis 9. And a push rod 105 connected to the.

  The brake mechanism 2 includes a booster mechanism (brake booster) 5 provided in the engine compartment ER, a brake master cylinder 6 provided integrally with the booster mechanism 5, and a reservoir connected to the brake master cylinder 6. And a tank 7.

  The push rod 105 is connected to the brake mechanism 2. Here, when the driver depresses the brake pedal 10a, the push rod 105 is displaced toward the brake mechanism 2 and the brake master cylinder 6 functions. And the brake device provided in each wheel is driven by the hydraulic pressure from the brake master cylinder 6.

  On the other hand, when the driver removes his / her foot from the brake pedal 10a, the push rod 105 is displaced away from the brake mechanism 2 by rotating counterclockwise by the biasing force from the spring 8.

  Here, the push rod 105 is provided between the divided push rod 102, the divided push rod 103, and the divided push rod 102 and the divided push rod 103, and elastically connects the divided push rod 103 and the divided push rod 102. Member 101. For this reason, it can suppress that the vibration from the brake mechanism 2 is transmitted to the division | segmentation push rod 103 from the division | segmentation push rod 102.
