リーブ５のフＡ−り溝６に」■合している。83 in Fig. 1, 1 is the rear output shaft to which the driving force from the 1F, 5 engine is transmitted, and the output shaft 2 is set opposite to the direction of the rear output shaft. . A rear spline 3 and a front spline 4 are formed on the outer periphery of the rear output shaft 1 and the front output shaft 2, respectively.
In the illustrated 2WD state, the coupling sleeve 5 that has covered the fork groove is on the rear spline 3 side. 7 is Schiff 1~
A shift rod that moves in the axial direction by operating a lever.
A shift fork 8 made of resin is attached to the shift rod 7, and a bifurcated fork pawl 9 is fitted into a flange 6 of the coupling sleeve 5.

When the shifter 1 operation is performed to switch to WD, the shifter 7 moves to the right by the specified amount determined by the shifter 1 operation, and the coupling sleeve 5 also moves to the right side by the fork 8 to shift 1. move to. However, freon 1 to spline 4
Since the phase between the rear spline 3 and the rear spline 3 was in the initial stage C, the coupling sleeve 5 (spline 1 - spline 4) was engaged and stopped in a 2WD state.

The spring 8 pushes the coupling sleeve 5 to the right side by the repulsive force of the spring 11.

った。However, in the conventional shaft support structure of the shift 1 to fork 8 made of resin, oil and air are sealed in the stepped collar 12 and 13 in the shaft hole 10 of the shift 1 and fork 8. As shown in Fig. 3, when the shift rod 7 moves, the discharge of oil and air is slow, and the movement of shiftrons 1 to '7 becomes heavy due to the pumping effect caused by the compression of the contained air. rear spline 3
Even when the coupling sleeve 5 is fitted by the spring force when the front spline 4 and the front spline 4 are in phase, the suction of air into the spring storage section is slow, resulting in a negative pressure state, and the coupling sleeve 5 is forced into the front spline 4. There was a risk that the +S insertion would not be done quickly.

が妨けられるという問題があった。Therefore, it is conceivable to provide ventilation holes 1B in the shifters 1 to 4-8 as shown by broken lines to communicate the spring housing to the outside, but the ventilation holes 18 can be formed by drilling. This makes machining time-consuming, and drilling tends to cause burrs on the shaft hole circumference of the shift shaft.
There was a problem in that the movement of the J51 collar inside the shaft hole was obstructed due to the occurrence of cracks.

The ventilation 1VI11 is arranged in stages.

A pair of stepped collars 12.13 are incorporated into the shaft hole 10 of the shift fork 8, and the stepped collars 12.13 abut against the stepped portion of a stopper ring 14.15 fitted into the front end of the shaft hole 1o. A step (=J collar 12.13) by a stopper ring 16.17 positioned in the shaft hole 10 at
The spring 11 is positioned between the stepped collars 12 and 13 by abutting against the small diameter end of the shift rod 7 .

態する。Figure 5 shows the stepped collar 1 d'31:J in the embodiment of Figure 4.
2, the stepped collar 12 has a stepped outer peripheral shape with a small diameter part 12a and a large diameter part 12b, and has a shaft hole 12c into which a shift rod is inserted. A ventilation groove 20 running in the axial direction is formed on the circumferential surface of the large diameter portion 12b. 5 Next, to explain the present invention in detail, when the shift rod 7 is moved to the right in order to switch to 4WD, the stopper ring with β: 6 is moved to shift 1 to 1-1 to 7. 1
Due to G, the fourth collar 12 is pushed and the spring 11
The compressed spring 11 (7) pushes the shift lever 8 to the right with the knob, and the knob 9 engages the knob 11 (7) with the knob 11 (7) to the right. It is pressed against the end of the front spline.

ることは無い。At this time, the spring 11 will be compressed by the movement of the stepped collar 12, but since the large diameter part of the stepped collar 12 is formed with an axial ventilation groove 20, the spring 11 will be compressed. Air and oil pass through the ventilation groove 20 to the outside 1
The movement of the shift rod 7 does not become heavy due to the pumping effect of the air taken out and stuffed into the spring storage part 10.

る。Next, when the splines of the rear output shaft and the splines of the Freon mill output shaft match in phase with the spring 11 being compressed, the horn ring sleeve fits into the front spline due to the force of the spring 11, and the previously compressed The spring 11 returns to the initial state shown in FIG.
Since the outside air easily flows through the ventilation groove 20 formed in the collar 12, the coupling sleeve can be quickly fitted by the spring force that matches the phase of the splines on the rear 1 [θ) axis and the front output shaft. I can do it.

とが出来る。FIG. 6 is a cross-sectional view and a side view showing another embodiment of the tiered collar used in the present invention. In the embodiment shown in FIG. However, this embodiment is characterized in that a ventilation groove 20 is formed on the inner peripheral surface of the shaft hole 12C into which the shift rod is inserted. - The spring storage part of the spring A- is communicated with the outside through the ventilation groove 20 of the shaft hole 12c, thereby preventing the pumping action when the spring is compressed and the generation of negative pressure in the spring storage part when the spring returns to its original state. You can.

望ましい。In addition, when the ventilation groove 20 is formed in the shaft hole '12C of the stepped noller 12 shown in FIG. 6, as is clear from FIG. The outside opening of the ventilation groove 20 should not be connected to the stopper ring 1.
It is desirable to cut out the contact area of 6 and widen it twice.

が出来るという効果が得られる。As explained above, according to the present invention, 1! As a shaft support structure for the A-ri shaft, the stepped collar of the base 1 is slidably assembled between the fork shaft hole and the fork shaft hole. The outer peripheral surface that comes into contact with the shift fork shaft hole (J) or the inner peripheral surface that slides into contact with the shift fork shaft hole has a ventilation groove that communicates the spring storage part to the outside. Spring storage compartment 1.1 in partitioned shifter 1 heft A
The ventilation of the stepped collar is always connected to the outside through the seedlings, and the spring compression due to the shift [- operation is 0.
5) It reliably prevents the shift 1-rond movement from becoming heavy due to the pumping action that occurs in step 5), and also prevents the compressed spring from returning, so the spring force is applied to the shaft spline of the coupling sleeve. It is possible to easily fit the fork into the resin shifter 1 which is equipped with the t5 mechanism by 1d^, thereby ensuring smooth operation of the fork.

ある。In the above example, the ventilation grooves are formed in one stage (=J collar), but the stage with the ventilation grooves to the right (=J collar and the stage A without ventilation grooves) are manufactured separately. -to(,
1. Since this is inconvenient, it is of course possible to use the same ventilation grooves for the -j collars on both sides.
