The side face of the protrusion 25 has a fitting hole for fitting the select operation shaft 5. 26 is provided. Further, a key groove portion 27 extending along the axial direction of the select operation shaft 5 is formed at the tip of the protruding portion 25, and the protruding piece portion 28a of the guide key 28 is fitted and arranged in the key groove portion 27. Thus, the striker 7 can slide along the axial direction of the select operation shaft 5 while the striker 7 is rotationally restricted. The base portion 28b of the guide key 28 is fixed to the housing 4 with a tightening bolt 29.

On the other hand, the main body portion 24 has a rectangular concave portion 21 formed on the surface 24a opposite to the protruding portion 25, and a half-cut surface is formed at a substantially central position of the bottom surface 21a of the concave portion 21. An arcuate groove 30 is formed orthogonal to the axial direction of the select operation shaft 5, and one end of the recess 21 and the groove 30 extends to the side surface 24b of the main body 24 and is open. Then, on the other side surface 24c of the main body portion 24, a screw hole (not shown) penetrating the above-mentioned recess 21 is formed.

A bolt 31 is screwed into the screw hole from the side surface 24 c side of the main body 24, and a nut 32 is screwed into the bolt 31 to fix the bolt 31 to the striker 7. .. The bolt 31 is made of a non-magnetic material such as aluminum, and one magnet 33 is embedded in the upper surface of its head 31a as shown in FIG. Further, in the housing portion 4c in which the striker 7 is housed, a magnetoelectric conversion element 34 is attached at a position corresponding to the movement path of the magnet 33 of the bolt 31, and the four sensitive portions 35 of this element 34 are arranged at equal intervals. Are arranged in a line in parallel with the selection operation shaft 5. Thus, the magnet 33 and the magnetoelectric conversion element 34 constitute a position detection mechanism S, and in response to the magnet 33 facing the sensitive portion 35 of the magnetoelectric conversion element 34, a predetermined detection signal ( The ON signal) is input to the controller (not shown) via the coaxial cable 36. The relative position of the bolt 31 with respect to the striker 7 can be arbitrarily adjusted by rotating the groove 31c formed at the tip of the screw portion 31b with a screwdriver or the like.

On the other hand, the striker 7, to which the bolt 31 is screwed, is fitted and arranged at a predetermined position of the selecting operation shaft 5 through the fitting hole 26, and a pair of semicircular split stopper ring members are provided on both sides. 37, 38 and 39, 40 integrally fix the selection operation shaft 5 in the axial direction. In FIG. 1 and the like, the stopper ring members 37 and 38 located on the left side and the stopper ring members 39 and 40 located on the right side are fitted into circumferential grooves 41 and 42 formed on the outer peripheral surface of the select operation shaft 5, respectively. The left stopper ring members 37 and 38 are locked by a groove 43 formed in the striker 7 so as not to separate in the radial direction of the select operation shaft 5.

The right stopper ring members 39 and 40 are arranged such that the large diameter portions 39 a and 40 a that contact the side surfaces of the striker 7 and the inner peripheral surface of the ring-shaped locking member 44 that contacts the outer peripheral surface thereof. The locking member 44 is formed with a through hole 45 corresponding to the air vent hole 16 of the selection operation shaft 5 in the radial direction, and the air vent hole 16 is closed by the locking member 44. It is configured not to be. Further, the locking member 44 is slightly smaller than the outer diameters of the large diameter portions 39a, 40a of the stopped stopper ring members 39, 40 in the state of being attached to the small diameter portions 39b, 40b of the stopper ring members 39, 40. Is formed. The right stopper ring member 39, 40 is provided with the engaging pin 46 through the through hole 45 and the air bleeding hole in a state where a part of the locking member 44 is overlapped with the outer peripheral surface of the small diameter portions 39b, 40b. By being inserted into 16, the selection operation shaft 5 is locked so as not to separate in the radial direction. In addition, the engaging pin 46 is formed with a groove portion 46a extending along the axial direction in order to have elasticity so that the engaging pin 46 does not block the air vent hole 16 and the through hole 45. The inner peripheral surfaces of these holes are crimped so that they do not fall off.

An engaging portion 23 at one end of the power transmission lever 22 is engaged and connected in the recess 21 of the striker 7. The engaging portion 23 of the power transmission lever 22 has both side portions 23a and 23b slidably contacting with the engaging surfaces 20a and 20b of the recess 21 of the striker 7. Then, as the striker 7 is moved, a pressing force acts on the engaging portion 23 of the power transmission lever 22 from the striker 7, and accordingly, the power transmission lever 22 rotates about the shaft 47. A shift operation shaft (not shown) is configured to move in the axial direction via an actuating lever (not shown) that is moved and rotated accordingly.

Next, the operation of the transmission operating device 1 having the above configuration will be described.

First, when the change lever (not shown) is operated in the select direction, the compressed air to the chambers 8a, 8b, 9a, 9b of the select operation actuator 2 is compressed based on the control signal from the controller (not shown). Are supplied and discharged, and accordingly, the selection operation shaft 5 is positioned at one of the four selection positions. Along with this, the magnet 33 is arranged so as to face one of the sensitive portions 35 of the magnetoelectric conversion element 34, so that a select position detection signal (ON signal) from the sensitive portion 35 is transmitted via the coaxial cable 36 to a controller (not shown). Is input to the selection operation shaft 5, whereby the operation of the selection operation shaft 5 is detected and the operation of the shaft 5 is stopped, and the selection operation is completed.

After that, when the change lever is operated in the shift direction and is put into the first speed, for example, a predetermined control signal is sent from a controller (not shown) based on the change signal and the selection completion signal from the position detection mechanism S. Is output, the shift operation actuator 3 is operated, and the gear is put into the first speed. Then, when the change lever is switched again to neutral, the shift operating actuator 3 and the select operating actuator 2 are moved back, and are again placed under the neutral state.

In the transmission operating device 1 of the present embodiment, the small diameter portions 39b, 40b of the right semicircular split stopper ring members 39, 40 fitted in the circumferential groove 42 of the select operation shaft 5 are engaged with the small diameter portions 39b, 40b. Since the stopper ring members 39 and 40 are locked by inserting the engaging pin 46 into the through hole 45 and the air bleeding hole 16 while arranging a part of the stopper ring 44 so as to overlap with each other, the locking member 44 serves as a stopper ring. The striker 7 does not disengage from the members 39 and 40, and therefore the striker 7 does not move in the axial direction of the select operation shaft 5 due to the engaging action of the circumferential groove 42 and the stopper ring members 39 and 40. 7 can be securely fixed to the operation shaft 5, and both members are integrated in the axial direction.

The locking member 44 is formed to be slightly smaller than the outer diameters of the large diameter portions 39a, 40a of the right side stopper ring members 39, 40 fitted and arranged in the circumferential groove 42 of the select operation shaft 5. Moreover, since the engagement pin 46 does not project to the outside from the outer peripheral surface of the locking member 44 (see FIGS. 3 and 4), the space B between the locking member 44 and the like and the housing portion 4c should be narrowed. In addition, the engagement pin 46 does not come into contact with the guide key 28 during the operation of the operating device 1, and the stopper ring members 39, 40 do not fall off the selecting operation shaft 5. Moreover, since the engagement pin 46 is inserted by utilizing the air vent hole 16 of the operation shaft 5, there is no increase in processing cost and the like.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications and changes can be made based on the technical idea of the present invention. It

For example, in the above-described embodiment, the left semicircular divided stopper ring members 37, 38 are locked by the recessed groove 43 formed in the striker 7, but the stopper ring members 37, 38 on the right side are locked. Similar to the semicircular split stopper ring members 39 and 40, the locking member 44 and the engaging pin 46 can be used for locking.

[0026]

[Effect of the device]

 As described above, the transmission operating device according to the present invention is provided with a transmission operating shaft slidably arranged in the housing and having an air vent hole, and a striker to which one end of the power transmission lever is connected. While forming a peripheral groove on the outer peripheral surface of the speed change operation shaft, a ring-shaped locking member having a through hole is provided, and a pair of semi-circular divided stopper ring members are fitted into the peripheral groove, and these stoppers are provided. By disposing the inner peripheral surface of the locking member in contact with the outer peripheral surface of the ring member and inserting the engaging pin into the through hole and the air vent hole to lock the stopper ring member, the gear shift operation is performed. Since the striker is integrally fixed to the work shaft in the axial direction, the assembly work can be done easily, and it is possible to use stopper ring members and locking members with a smaller diameter than before. It can reduce the size of the narrow to the equipment space between these two members and the housing. Further, since the engaging pin is inserted into the through hole and the air bleeding hole and does not project from the outer peripheral surface of the locking member, it does not interfere with other constituent members during operation of the device and slips out of the locking member. There is no fear that the locking action of the locking member with respect to the stopper ring member will be released, and therefore the striker can be reliably fixed to the gear shift operation shaft.
