Description

  The present invention relates to a shift device for a manual transmission, and more particularly, to a shift device for a manual transmission having a restricting unit that provides different operation feelings depending on the operation direction of a shift lever by a driver.

As a conventional shift device of this type of manual transmission, a retainer that rotatably supports a shift lever is formed in a bifurcated shape toward the manual transmission, and the two front end portions branched and the manual transmission There is known a structure in which an elastic member is provided at each joint portion, and the front end portion of the retainer and the manual transmission are elastically coupled to each other (see, for example, Patent Document 1).
Further, in the manual transmission shift device described in Patent Document 1, as shown in FIGS. 11A to 11C, the joint 100 on the manual transmission side of the joint 100 at the front end of the retainer 101 is used. A long hole-shaped opening 102b extending in the front-rear direction is formed in the side surface 102a of the cylindrical member 102 through which the fixing pin 111 fixed to the hole 110a of the U-shaped yoke 110 is inserted, and the opening 102b By making the vertical width of the shaft larger than the diameter of the fixed pin 111, vibration transmitted from the engine can be absorbed by the elastic member 120 accommodated in the cylindrical member 102, and a good operating feeling of the shift lever can be obtained. it can.

  That is, when the driver performs a shift operation (operation in the front-rear direction of the shift lever), as shown in FIG. 12A, the fixing pin 111 is allowed to move in the front-rear direction within the opening 102b. As shown in FIG. 12B, the fixing pin 111 is opened when the driver performs a selection operation (operation of the shift lever in the left-right direction) with a large operation force. By coming into contact with the inner edge of the portion 102b, a moderate feeling of operation can be obtained.

JP 2004-58825 A

  However, in such a shift device of a conventional manual transmission, the operation feeling required at the time of the shift operation is different from the operation feeling required at the time of the select operation. If the rigidity of the elastic member is weakened for further smoothness, the elastic member cannot absorb the vibration transmitted from the engine, and the fixing pin collides with the inner edge of the opening 102b even when the selection operation is not performed. There was a problem that an unpleasant interference sound (battering sound) was generated due to a collision.

  The present invention has been made in order to solve the above-described conventional problems, and is capable of obtaining a good operation feeling of the shift lever and a manual transmission capable of preventing the generation of unpleasant interference sound.

The rigidity of the member in a direction orthogonal to the shift operation direction is higher than that of the elastic member in the shift operation direction.

  With this configuration, since the amount of deformation of the elastic member in the direction orthogonal to the shift operation direction is reduced, it is possible to prevent an unpleasant interference sound from being generated due to vibration in the regulating means.

  Further, when the shift lever is shifted, the restricting means allows the elastic member to be deformed in the shift operation direction, so that a smooth operation feeling during the shift operation can be realized.

  In addition, when the shift lever is operated in a direction orthogonal to the shift operation direction, the restricting means restricts deformation of the elastic member in the direction orthogonal to the shift operation direction, thereby realizing a moderate operation feeling. Can do.

  As a result, it is possible to obtain a favorable operation feeling of the shift lever and to prevent generation of unpleasant interference sound.

  With this configuration, since the elastic member is locked by the engagement between the first locking portion and the second locking portion, it is possible to prevent the posture of the elastic member from changing.

  In the shift device for a manual transmission according to the present invention, in (2), (3) the elastic member includes a cavity arranged in the shift operation direction.

  With this configuration, since the outer shape of the elastic member is the same as when the cavity is not provided inside, an elastic member whose rigidity in the direction orthogonal to the shift operation direction is higher than that in the shift operation direction is It can be assembled in the same way.

  In the shift device for a manual transmission according to the present invention, in (2), (4) the elastic member has a gap between one end portion of the retainer in the shift operation direction and the shift operation direction. In the direction orthogonal to the one end of the retainer.

  The shift lever 11 is arranged to extend in the vertical direction in order to perform a shifting operation of the manual transmission 50, and a knob 11a is attached to the upper end portion thereof. A large spherical portion 12 that functions as a ball joint is provided below the center of the shift lever 11. The shift lever 11 is swingable in the shift direction, that is, in the front-rear direction, with the large spherical portion 12 as a center, with the large spherical portion 12 being accommodated in the accommodating portion 15 formed in the central portion 14c of the retainer 14. .

  A small ball portion 13 that functions as a ball joint is provided at a lower end than the center of the shift lever 11, and the shift lever 11 and the rod 76 are connected by the small ball portion 13. The shift lever 11 can swing in the select direction, that is, in the left-right direction, with the small ball portion 13 as a center, in a state where the shift lever 11 and the rod 76 are connected in the small ball portion 13.

  Note that the portion of the shift lever 11 that protrudes into the vehicle compartment and that is below the knob 11a is covered with a dustproof boot (not shown), and dust enters the retainer 14, the large sphere portion 12, and the like. It is designed to prevent this.

  The retainer 14 is integrally formed by aluminum casting or the like, and is formed in a substantially Y-shape that is bifurcated forward when viewed from above.

  The central portion 14c of the retainer 14 is formed in a trapezoidal flat plate shape when viewed from above, and includes a housing portion 15 that houses the large spherical portion 12 and rotatably supports it.

  The rear portion 14d of the retainer 14 is formed in a tubular shape extending rearward from the central portion 14c, and is elastically fixed and supported on the vehicle body 20 via the elastic member 18.

  The left front portion 14a of the retainer 14 is formed in a tubular shape extending in the front-rear direction from the left front of the central portion 14c, and elastically connected to the left rear end portion of the manual transmission 50 via the joint 16 having the elastic member 81. It is supported by.

  The right front portion 14b of the retainer 14 is formed in a tubular shape extending in the front-rear direction from the right front of the central portion 14c, and elastically attached to the right rear end portion of the manual transmission 50 via the joint 26 having the elastic member 81. It is supported by. The left front portion 14a and the right front portion 14b of the retainer 14 are formed symmetrically with respect to the central portion 14c.

  As described above, the retainer 14 is supported by the rear end portion of the vehicle body 20 or the manual transmission 50 at the three points of the rear end portion 14d, the left front portion 14a, and the right front portion 14b.

  The manual transmission 50 is for adjusting the gear ratio of rotation when transmitting the rotation from the engine 40 to drive wheels (not shown), and the gear ratio is changed by shifting and selecting the shift lever 11. Has been changed.

  As shown in FIG. 2, an input shaft 58 and an output shaft 59 that extend coaxially with each other and a reverse shaft 60 that extends in parallel with the input shaft 58 and the output shaft 59 rotate in the housing 57 of the manual transmission 50. Supported as possible. The input shaft 58 is connected to a crankshaft (not shown) of the engine 40 via a clutch, and the output shaft 59 is connected to the propeller shaft 75.

  A drive gear 61 is fixed to the input shaft 58. The drive gear 61 is engaged with a driven gear 62 fixed to the reversing shaft 60. In addition, gears 63 to 66 are fixed to the driven gear 62 sequentially from the end on the input shaft 58 side to the end on the output shaft 59 side. On the other hand, a low gear 67, a second gear 68, a third gear 69, and a fifth gear 70 are attached to the output shaft 59 so as to be rotatable with respect to the output shaft 59. The low gear 67, the second gear 68, the third gear 69, and the fifth gear 70 are engaged with the gear 65, the gear 64, the gear 63, and the gear 66 of the reversing shaft 60, respectively.

  Therefore, the rotation transmitted from the engine 40 to the input shaft 58 is transmitted to the low gear 67, the second gear 68, the third gear 69, and the fifth gear 70 via the drive gear 61, the driven gear 62, the reverse shaft 60, and the gears 63 to 66. Each is transmitted. By transmitting the rotation, the low gear 67, the second gear 68, the third gear 69, and the fifth gear 70 rotate about the output shaft 59 with respect to the output shaft 59.

  In the output shaft 59, first to third synchromesh mechanisms 71 to 73 are provided between the third gear 69 and the drive gear 61, between the low gear 67 and the second gear 68, and on the side of the fifth gear 70, respectively. ing. These first to third synchromesh mechanisms 71 to 73 are for switching the rotation transmission path from the input shaft 58 to the output shaft 59.

  The first to third synchromesh mechanisms 71 to 73 are connected to the shift lever 11 via a shifter arm 74 and a rod 76. When the shift lever 11 is switched in stages between the first to fifth shift positions, the manual transmission 50 is shifted and output from the input shaft 58 according to the shift position of the shift lever 11. The transmission path of rotation to the shaft 59 is changed.

  That is, in a general H-type shift pattern, when the shift lever 11 is selected from the neutral position to the left and then shifted forward to switch to the first speed shift position, the switching operation is performed by the shifter arm 74. Are transmitted to the first to third synchromesh mechanisms 71 to 73 via the rod 76, and the low gear 67 is fixed to the output shaft 59 by the second synchromesh mechanism 72. In this case, rotation transmission from the engine 40 side to the drive wheel side is performed via the input shaft 58, the drive gear 61, the driven gear 62, the reverse shaft 60, the gear 65, the low gear 67, and the output shaft 59. .

  When the shift lever 11 is shifted backward from the first-speed shift position and switched to the second-speed shift position, the switching operation is performed via the shifter arm 74 and the rod 76 to the first to third synchromesh mechanisms 71 to 73. The second gear 68 is fixed to the output shaft 59 by the second synchromesh mechanism 72. In this case, transmission of rotation from the engine 40 side to the drive wheel side is performed via the input shaft 58, the drive gear 61, the driven gear 62, the reverse shaft 60, the gear 64, the second gear 68, and the output shaft 59. Become.

  Further, when the shift lever 11 is switched to the third speed shift position through the shift operation from the second speed shift position to the front, the select operation to the right, and the shift operation to the front, the switching operation is performed with the shifter arm 74. It is transmitted to the first to third synchromesh mechanisms 71 to 73 through the rod 76, and the third gear 69 is fixed to the output shaft 59 by the first synchromesh mechanism 71. In this case, rotation transmission from the engine 40 side to the drive wheel side is performed via the input shaft 58, the drive gear 61, the driven gear 62, the reverse shaft 60, the gear 63, the third gear 69, and the output shaft 59. .

  When the shift lever 11 is shifted backward from the 3rd speed shift position and switched to the 4th speed shift position, the switching operation is performed via the shifter arm 74 and the rod 76 to the first to third synchromesh mechanisms 71 to 73. Then, the input shaft 58 and the output shaft 59 are fixed by the first synchromesh mechanism 71. In this case, rotation transmission from the engine 40 side to the drive wheel side is performed via the input shaft 58 and the output shaft 59.

  Further, when the shift lever 11 is switched to the 5-speed shift position through the shift operation forward from the 4-speed shift position, the select operation in the right direction, and the shift operation in the forward direction, the switching operation is performed with the shifter arm 74. It is transmitted to the first to third synchromesh mechanisms 71 to 73 via the rod 76, and the fifth gear 70 is fixed to the output shaft 59 by the third synchromesh mechanism 73. In this case, rotation transmission from the engine 40 side to the drive wheel side is performed via the input shaft 58, the drive gear 61, the driven gear 62, the reverse shaft 60, the gear 66, the fifth gear 70, and the output shaft 59. .

  Accordingly, the transmission path of rotation from the engine 40 side to the drive wheel side becomes different based on the shift operation and the selection operation between the first speed to the fifth speed of the shift lever 11, and the engine 40 side according to these transmission paths. The gear ratio of the rotation transmitted from the motor to the drive wheel side is adjusted. That is, a gear for transmitting rotation from the engine 40 side to the drive wheel side is selected based on the transmission of the shift lever 11, and the selected gear has a diameter and the number of teeth for each shift position of 1st to 5th gears. Set to something different. The gear diameter and the number of teeth are set so that the gear ratio of the rotation transmitted from the engine 40 side to the wheel side gradually decreases as the shift position changes from the first speed to the fifth speed. .

  Here, details of the joints 16 and 26 will be described. In addition, since the joint 16 and the joint 26 have the same structure arrange | positioned symmetrically with respect to the retainer 14, the joint 16 is demonstrated below.

  As shown in FIGS. 3A to 3C, 4, and 5, the joint 16 includes a cylindrical member 35 having a bottomed cylindrical shape that is integrally provided at the distal end of the retainer 14, and a cylinder. A cylindrical elastic member 81 accommodated in the member 35 and a fixed pin 79 inserted and fixed to the yoke 78 at the left rear end of the manual transmission 50 are configured. FIG. 3B shows a state viewed from the back side of FIG.

  The cylindrical member 35 is integrally provided at the tip of the retainer 14 by means such as welding, and includes a side plate 35d on one side surface in which an elongated hole-shaped opening 35c extending in the front-rear direction is formed. . A convex portion 35a is formed on the upper end of the inner peripheral surface of the cylindrical member 35, and a convex portion 35b is formed on the lower end of the inner peripheral surface of the cylindrical member 35. The convex portions 35a and 35b are elastic. The member 81 is locked so that the posture of the member 81 does not change. The convex portions 35a and 35b in the present embodiment constitute a first locking portion in the present invention.

  The elastic member 81 is formed by forming elastic rubber, resin, or the like into a cylindrical shape, and a concave portion 81a that engages with a convex portion 35a formed at the upper end of the inner peripheral surface of the cylindrical member 35 is formed at the upper end of the outer peripheral surface. A recess 81b that is formed and engages with a protrusion 35b formed at the lower end of the inner peripheral surface of the cylindrical member 35 is formed at the lower end of the outer peripheral surface. The concave portions 81a and 81b in the present embodiment constitute a second locking portion in the present invention.

  An insertion hole 81 c into which the fixing pin 79 is inserted is formed at the center of the elastic member 81. In addition, substantially arc-shaped cavities 81 d and 81 e centering on the insertion hole 81 c are formed inside the elastic member 81. The cavity 81d is disposed in front of the insertion hole 81c, and the cavity 81e is disposed behind the insertion hole 81c.

  On the other hand, a U-shaped yoke 78 is fixed to the left rear end portion of the manual transmission 50. The yoke 78 is formed with a fixing hole 78a in which a fixing pin 79 is fixed by screwing or the like. Yes.

  In the joint 16 configured as described above, after the elastic member 81 is accommodated in the cylindrical member 35, the fixing pin 79 is inserted in a state where the axes of the insertion hole 81 c of the elastic member 81 and the fixing hole 78 a of the yoke 78 are aligned. Assembling is performed by being inserted into the insertion hole 81 c of the elastic member 81 and being fixed to the fixing hole 78 a of the yoke 78. The cylindrical member 35 in the present embodiment constitutes one end of the retainer in the present invention, and the fixing pin 79 in the present embodiment constitutes a support member in the present invention. In addition, the opening 35c and the fixing pin 79 in the present embodiment constitute a regulating means in the present invention.

Next, the operation will be described.
When the shift lever 11 is shifted, the retainer 14 moves the large spherical portion 12 as the shift lever 11 swings about the large spherical portion 12 and the rod 76 and the shifter arm 74 slide back and forth. A force in the front-rear direction is applied via.

  When a force in the front-rear direction is applied to the retainer 14, the elastic member 81 of the joints 16, 26 is deformed in the front-rear direction by the force in the front-rear direction, and the inside of the opening 35 c is fixed by an amount that the elastic member 81 is deformed in the front-rear direction. The pin 79 moves in the front-rear direction. At this time, since the opening 35c is formed in a long hole shape extending in the front-rear direction, the fixing pin 79 is allowed to move in the front-rear direction.

  Accordingly, when the shift lever 11 is shifted, the force in the front-rear direction acting on the retainer 14 deforms the elastic member 81, and the movement of the retainer 14 in the front-rear direction is allowed by the elongated hole-shaped opening 35c. So give the driver a smooth operation feeling.

  In this embodiment, since the cavities 81d and 81e are formed in the elastic member 81 before and after the insertion hole 81c, the rigidity of the elastic member 81 in the front-rear direction is weakened. As described above, when one of the cavities 81d and 81e expands and the other contracts, the elastic member 81 is deformed in the front-rear direction more than when the cavities 81d and 81e are not formed, and the shift lever 11 is shifted. The operation feeling given to the driver when operated becomes smoother. FIG. 6A shows a state where the shift lever 11 is shifted forward and a forward force is applied to the retainer 14.

  Further, when the shift lever 11 is selected, the retainer 14 swings around the small ball portion 13 and the rod 76 and the shifter arm 74 rotate as the shift lever 11 rotates about the small ball portion 12. The force which inclines the retainer 14 to the left-right direction acts via.

  Due to the force that tilts the retainer 14 in the left-right direction, a force that deforms the elastic member 81 in the vertical direction, that is, the direction orthogonal to the shift operation direction, is generated in the elastic member 81 of the joints 16 and 26. Specifically, an upward force acts on one elastic member 81 of the joints 16 and 26, and a downward force acts on the other elastic member 81 of the joints 16 and 26. When an upward or downward force is applied to the elastic member 81, as shown in FIG. 6B, the elastic member 81 is deformed to a certain extent, and the fixing pin 79 moves upward or downward in the opening 35c. After the movement, the fixing pin 79 comes into contact with the inner edge of the opening 35c, so that the movement of the fixing pin 79 is restricted. When the shift lever 11 is selected, the driver feels moderation. Give the ring. FIG. 6B shows a state of the elastic member 81 of the joint 16 when the shift lever 11 is shifted to the left and a force that tilts the retainer 14 to the left is applied. Further, since the elasticity of the elastic member 81 in the vertical direction is not affected by the cavities 81d and 81e and is not weakened, the fixing pin 79 collides with the inner edge of the opening 35c due to the vibration of the engine 40 and is uncomfortable. No interference sound is generated.

  As described above, in the shift device for a manual transmission according to the first embodiment of the present invention, the rigidity in the direction orthogonal to the shift operation direction of the elastic member 81 is the rigidity of the elastic member 81 in the shift operation direction. Compared to a higher configuration.

  For this reason, since the amount of deformation of the elastic member 81 in the direction orthogonal to the shift operation direction is reduced, the fixing pin 79 collides with the inner edge of the opening 35c due to the vibration of the engine 40, and an unpleasant interference sound is generated. Can be prevented.

  Further, when the shift lever 11 is shifted, the force in the front-rear direction acting on the retainer 14 deforms the elastic member 81, and the movement of the retainer 14 in the front-rear direction is allowed by the elongated hole-shaped opening 35c. Therefore, a smooth operation feeling during the shift operation can be realized.

  Further, when the shift lever 11 is selected, the fixing pin 79 comes into contact with the inner edge of the opening 35c after the elastic member 81 is elastically deformed, so that an operational feeling with a moderation feeling during the selection operation is realized. be able to.

  Therefore, it is possible to obtain a good operation feeling of the shift lever 11 both during the shift operation and during the select operation, and it is possible to prevent generation of unpleasant interference sound.

  In the shift device for a manual transmission according to the first embodiment of the present invention, the cylindrical member 35 at one end of the retainer 14 includes convex portions 35a and 35b for locking the elastic member 81, and the elastic member. 81 includes concave portions 81a and 81b that engage with the convex portions 35a and 35b.

  For this reason, it is possible to prevent the posture of the elastic member 81 from changing inside the cylindrical member 35 by engaging the convex portions 35a and 35b of the cylindrical member 35 with the concave portions 81a and 81b of the elastic member 81. it can.

  In the shift device for a manual transmission according to the first embodiment of the present invention, the elastic member 81 has cavities 81d and 81e arranged in the shift operation direction.

  For this reason, since the outer shape of the elastic member 81 is the same as the case where the cavities 81d and 81e are not provided therein, the elastic member has higher rigidity in the select direction orthogonal to the shift operation direction than in the shift operation direction. 81 can be assembled in a conventional manner.

(Second Embodiment)
This embodiment shows an example in which the configuration of the elastic member is changed. The same reference numerals are given to the same configurations as those of the above-described embodiment, and the description is omitted.

  As shown in FIG. 7, like the elastic member 81, the elastic member 82 is formed by forming elastic rubber, resin, or the like into a cylindrical shape, and is formed on the upper end of the inner peripheral surface of the cylindrical member 35. A concave portion 82a that engages with the portion 35a is formed at the upper end of the outer peripheral surface, and a concave portion 82b that engages with the convex portion 35b formed at the lower end of the inner peripheral surface of the cylindrical member 35 is formed at the lower end of the outer peripheral surface. Yes. The concave portions 82a and 82b in the present embodiment constitute a second locking portion in the present invention.

  An insertion hole 82 c through which the fixing pin 79 is inserted is formed at the center of the elastic member 82. The elastic member 82 has gaps 82d and 82e between the joints 16 and 26 at one end of the retainer 14 in the shift operation direction and closely contacts the cylindrical member 35 in the direction orthogonal to the shift operation direction. With this configuration, the rigidity of the elastic member 82 in the direction orthogonal to the shift operation direction is higher than the rigidity of the elastic member 82 in the shift operation direction. In the present embodiment, the elastic member 82 is formed in a substantially pincushion type. The shape of the elastic member 82 is such that gaps 82d and 82e are provided between the joints 16 and 26 at one end of the retainer 14 in the shift operation direction and the cylindrical member 35 and the cylindrical member 35 in the direction orthogonal to the shift operation direction. The shape is not limited to the pincushion type as long as it is in close contact, and may be, for example, a rectangle.

Next, the operation will be described.
When a longitudinal force is applied to the retainer 14 by the shift operation of the shift lever 11, the elastic member 82 of the joints 16 and 26 is deformed in the front-rear direction by the front-rear force, and the amount by which the elastic member 82 is deformed in the front-rear direction. The fixing pin 79 moves in the front-rear direction only within the opening 35c. At this time, since the opening 35c is formed in a long hole shape extending in the front-rear direction, the fixing pin 79 is allowed to move in the front-rear direction.

  Therefore, when the shift lever 11 is shifted, the force in the front-rear direction acting on the retainer 14 deforms the elastic member 82, and the retainer 14 is allowed to move in the front-rear direction by the elongated hole-shaped opening 35c. So give the driver a smooth operation feeling.

  In the present embodiment, the elastic member 82 has gaps 82d and 82e between the cylindrical member 35 of the joints 16 and 26 at one end of the retainer 14 in the shift operation direction, and the cylindrical member in the direction orthogonal to the shift operation direction. Since the rigidity in the front-rear direction of the elastic member 82 is weakened by being configured to be in close contact with 35, as shown in FIG. 8A, one of the gaps 82d and 82e is expanded and the other is reduced. Further, the elastic member 82 is deformed more in the front-rear direction, and the operation feeling given to the driver when the shift lever 11 is operated for shifting becomes smoother.

  Further, when the shift lever 11 is selected, the retainer 14 swings around the small ball portion 13 and the rod 76 and the shifter arm 74 rotate as the shift lever 11 rotates about the small ball portion 12. The force which inclines the retainer 14 to the left-right direction acts via.

  Due to the force that tilts the retainer 14 in the left-right direction, a force that deforms the elastic member 82 in the vertical direction is generated in the elastic member 82 of the joints 16, 26. That is, an upward force acts on one elastic member 82 of the joints 16 and 26, and a downward force acts on the other elastic member 82 of the joints 16 and 26. When the elastic member 82 is deformed in the vertical direction, as shown in FIG. 8B, after the fixed pin 79 moves in the vertical direction in the opening 35c by the amount of deformation, the fixed pin 79 becomes the inner edge of the opening 35c. When the shift lever 11 is selected, the driver feels a modest feeling of operation when the shift lever 11 is selected. Further, since the elasticity of the elastic member 82 in the vertical direction is not affected by the gaps 82d and 82e and is not weakened, the fixing pin 79 collides with the inner edge of the opening 35c due to the vibration of the engine 40 and is uncomfortable. No interference sound is generated.

  As described above, in the shift device for a manual transmission according to the second embodiment of the present invention, the elastic member 82 is between the cylindrical member 35 of the joints 16 and 26 at one end of the retainer 14 in the shift operation direction. Are formed so as to be in close contact with the cylindrical member 35 in a direction orthogonal to the shift operation direction.

  Therefore, the spaces 82d and 82e can be made larger by providing the spaces 82d and 82e between the cylindrical member 35 than when the cavities 81d and 81e are provided inside like the elastic member 81. Therefore, since the elastic member 82 can be greatly deformed by the gaps 82d and 82e, the operation feeling during the shift operation can be further smoothed.

(Third embodiment)
This embodiment shows an example in which the configuration of the elastic member is changed. The same reference numerals are given to the same configurations as those of the above-described embodiment, and the description is omitted.

  As shown in FIG. 9, the elastic member 83 is formed by forming elastic rubber, resin or the like in a cylindrical shape like the elastic members 81 and 82, and is formed at the upper end of the inner peripheral surface of the cylindrical member 35. A concave portion 83a that engages with the convex portion 35a is formed at the upper end of the outer peripheral surface, and a concave portion 83b that engages with the convex portion 35b formed at the lower end of the inner peripheral surface of the cylindrical member 35 is formed at the lower end of the outer peripheral surface. Has been. The recesses 83a and 83b in the present embodiment constitute a second locking portion in the present invention.

  An insertion hole 83c through which the fixing pin 79 is inserted is formed at the center of the elastic member 83. Further, the material in the direction orthogonal to the shift operation direction of the elastic member 83 is different from the material in the shift operation direction of the elastic member 83, so that the rigidity of the elastic member 83 in the direction orthogonal to the shift operation direction is elastic. The rigidity of the member 83 is set higher than the rigidity in the shift operation direction. Specifically, the material in the direction orthogonal to the shift operation direction of the elastic member 83 is composed of high rigidity members 83d and 83e having relatively high rigidity, and the material of the elastic member 83 in the shift operation direction is relatively rigid. It consists of low low-rigidity members 83f and 83g.

Next, the operation will be described.
When a force in the front-rear direction is applied to the retainer 14 by the shift operation of the shift lever 11, the amount of the elastic member 83 of the joints 16, 26 deformed in the front-rear direction by the force in the front-rear direction, and the amount of the elastic member 83 deformed in the front-rear direction. The fixing pin 79 moves in the front-rear direction only within the opening 35c. At this time, since the opening 35c is formed in a long hole shape extending in the front-rear direction, the fixing pin 79 is allowed to move in the front-rear direction.

  Therefore, when the shift lever 11 is shifted, the force in the front-rear direction acting on the retainer 14 deforms the elastic member 83, and the retainer 14 is allowed to move in the front-rear direction by the elongated hole-shaped opening 35c. So give the driver a smooth operation feeling.

  In the present embodiment, since the material in the direction orthogonal to the shift operation direction of the elastic member 83 is different from the material in the shift operation direction of the elastic member 83, the rigidity of the elastic member 83 in the front-rear direction is weakened. As shown in FIG. 10 (a), when one of the low-rigidity members 83f and 83g is expanded and the other is contracted, the elastic member 83 is deformed more in the front-rear direction, and the shift lever 11 is shifted. The operation feeling given to the driver when this is done becomes smoother.

  Further, when the shift lever 11 is selected, the retainer 14 swings around the small ball portion 13 and the rod 76 and the shifter arm 74 rotate as the shift lever 11 rotates about the small ball portion 12. The force which inclines the retainer 14 to the left-right direction acts via.

  Due to the force that tilts the retainer 14 in the left-right direction, a force that deforms the elastic member 83 in the vertical direction is generated in the elastic member 83 of the joints 16 and 26. That is, an upward force acts on one elastic member 83 of the joints 16 and 26, and a downward force acts on the other elastic member 83 of the joints 16 and 26. When the elastic member 83 is deformed in the vertical direction, as shown in FIG. 10B, the fixed pin 79 moves in the vertical direction within the opening 35c by the amount of deformation, and then the fixed pin 79 is the inner edge of the opening 35c. When the shift lever 11 is selected, the driver feels a modest feeling of operation when the shift lever 11 is selected. Further, since the elastic member 83 is composed of highly rigid members 83d and 83e in the vertical direction, the fixing pin 79 does not collide with the inner edge of the opening 35c due to the vibration of the engine 40, and unpleasant interference sound is not generated. .

  As described above, in the shift device for a manual transmission according to the third embodiment of the present invention, the material perpendicular to the shift operation direction of the elastic member 83 is the same as the material of the elastic member 83 in the shift operation direction. It has a different configuration.

  Therefore, the material of the high-rigidity members 83d and 83e in the direction orthogonal to the shift operation direction of the elastic member 83 and the material of the low-rigidity members 83f and 83g in the shift operation direction of the elastic member 83 can be selected with a high degree of freedom. Since the rigidity of the elastic member 83 in the direction orthogonal to the shift operation direction and the rigidity in the shift operation direction can be set optimally, the shift lever 11 can be operated well both during the shift operation and during the select operation. A feeling can be obtained and an unpleasant interference sound can be completely prevented.

  The manual transmission shift device according to the present invention has been specifically described with reference to the preferred embodiments, but the present invention is not limited to these embodiments. The present invention is not applied to a shift device of a manual transmission and produces an effect, but can be applied to other operation means having the same mechanism as those of these embodiments.

  As described above, the shift device for a manual transmission according to the present invention has an effect of being able to obtain a good operation feeling of the shift lever and to prevent generation of unpleasant interference sound. Therefore, it is useful for a shift device of a manual transmission or the like having a restricting means that gives different operation feelings depending on the operation direction of the shift lever by the driver.
