The screw hole has a side surface 24c of the main body 24.
Bolt 31 is screwed in from the side of
The bolt 31 is fastened and fixed to the striker 7 by screwing the nut 32 into the nut. The bolt 31 is made of a non-magnetic material such as aluminum, and a single magnet 33 is provided on the upper surface of the head 31a as shown in FIG.
Is embedded. A magneto-electric conversion element 34 is attached to the housing portion 4c in which the striker 7 is stored at a position corresponding to the movement path of the magnet 33 of the bolt 31, and the four sensitive portions 35 of the element 34 are arranged at equal intervals. They are arranged in a row in parallel with the select operation shaft 5. Thus, the position detection mechanism S is configured by the magnet 33 and the magneto-electric conversion element 34. In response to the magnet 33 facing the sensitive portion 35 of the magneto-electric conversion element 34, a predetermined detection signal (ON Signal) is input to a 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 a groove 31c formed at the tip of the screw portion 31b with a driver 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 both sides are respectively provided with a pair of semicircular divided stopper ring members 37, 37. 38 and 39,
Reference numeral 40 is used to integrally fix the select operation shaft 5 in the axial direction. In FIG. 1 and the like, stopper ring members 37 and 38 located on the left side and 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 selecting operation shaft 5 respectively. And the left stopper ring member 37,
Reference numeral 38 is locked by a concave 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, 40
Large-diameter portions 39a, 40a abutting on the side surface of striker 7
And small-diameter portions 39b and 40b arranged so that the inner peripheral surface of the ring-shaped locking member 44 abuts on the outer peripheral surface.
Are formed in the radial direction so that the air vent hole 16 is not closed by the locking member 44. In addition, the locking member 44 is connected to the stopper ring member 3.
The large-diameter portions 39a, 39a of the stopper ring members 39, 40 locked in the state of being attached to the small-diameter portions 39b, 40b
It is formed to be slightly smaller than the outer diameter of 40a. Thus, the right stopper ring members 39, 40
With the engagement pin 46 inserted into the through hole 45 and the air vent hole 16 with the part of the locking member 44 overlapping the outer peripheral surface of the small diameter portions 39b and 40b, the diameter of the select operation shaft 5 is reduced. Locked so as not to separate in the direction. The engaging pin 46 is formed with a groove 46a over the entire length in the axial direction in order to provide elasticity, so that the engaging pin 46 does not block the air vent hole 16 and the through hole 45, and It is designed so that it does not fall off by being pressed against the inner peripheral surface.

In the recess 21 of the striker 7, an engaging portion 23 at one end of a power transmission lever 22 is engaged and connected. Engaging part 23 of power transmission lever 22
The two sides 23a and 23b are in sliding contact with the engagement 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 the power transmission lever 22 rotates around the shaft 47 in response thereto. The shift operation shaft (not shown) is configured to move in the axial direction thereof via an operation lever (not shown) which is rotated in accordance with the operation.

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

First, when a change lever (not shown) is operated in the select direction, the chambers 8a, 8a of the select operation actuator 2 are operated based on a control signal from a controller (not shown).
Supply and discharge of compressed air to and from 8b, 9a, and 9b are performed, and accordingly, the select operation shaft 5 is positioned at one of the four select positions. Along with this, the magnet 33 is arranged to face one of the sensitive parts 35 of the magneto-electric conversion element 34, so that the select position detection signal (ON signal) is sent from the sensitive part 35 to a controller (not shown) via the coaxial cable 36. When the input is input, it is detected that the select operation shaft 5 has been moved to the predetermined select position, the operation of the shaft 5 is stopped, and the select operation is completed.

Thereafter, when the change lever is operated in the shift direction and is engaged, for example, in the first speed, a predetermined control signal is output from a controller (not shown) based on the change signal and a selection completion signal from the position detection mechanism S. Is output, the shift operation actuator 3 is operated, and the gear is shifted to the first speed. Then, when the change lever is switched to neutral again, the shift operation actuator 3 and the select operation 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 39 of the right semicircular split stopper ring members 39, 40 which are fitted and arranged in the circumferential groove 42 of the select operation shaft 5.
b and 40b, a part of the locking member 44 is disposed so as to overlap, and the engaging pin 46 is inserted into the through hole 45 and the air vent hole 16 to stop the stopper ring members 39 and 4.
0, the locking member 44 does not come off the stopper ring members 39, 40, and therefore the circumferential groove 42
The striker 7 does not move in the axial direction of the selecting operation shaft 5 due to the engagement action between the striker 7 and the stopper ring members 39 and 40, and the striker 7 can be securely fixed to the operation shaft 5, and both members can be moved in the axial direction. Will be integrated with

The locking member 44 is formed to be slightly smaller than the outer diameter of the large-diameter portions 39a, 40a of the right stopper ring members 39, 40 fitted and arranged in the circumferential groove 42 of the select operation shaft 5, Further, the engaging pin 46 is connected to the locking member 44.
(See FIGS. 3 and 4), the locking member 44 and the housing portion 4c
Can be narrowed, the engaging pin 46 does not come into contact with the guide key 28 when the operating device 1 is operated, and the stopper ring members 39 and 40 are moved from the select operating shaft 5 Will not fall off. In addition, since the engagement pin 46 is inserted using the air vent hole 16 of the operation shaft 5, the processing cost and the like do not increase.

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

For example, in the above-described embodiment, the left semicircular divided stopper ring members 37, 38 are locked by the concave grooves 43 formed in the striker 7, but the stopper ring members 37, 38 are locked on the right side. Like the semicircular split stopper ring members 39 and 40, the stopper ring member 39 and the locking member 44 and the engagement pin 46 may be used to lock.
