  Next, the procedure for assembling the shift knob 23 to the tip of the shift lever 20 will be described. First, as a preparation before assembling the shift knob 23, the housing 10 is fixed to the vehicle body (not shown) in a state where the shift lever 20 having the pull rod 22 disposed in the cylinder is supported on the housing 10. After the select cover 11 is fixed to the housing 10 and a cover member (not shown) that covers the periphery of the shift lever device 1 is mounted on the vehicle body, the shift lever 20 is inserted into the select hole 12 of the select cover 11. The knob cover 40 and the shift knob 23 are assembled to the shift lever 20.

  The knob knob 27, the link body 33, and the auxiliary lever 34 are assembled to the link case 31 to the shift knob 23, and the link case 31 is mounted in the case housing chamber 29. At this time, the repulsive force of the return spring 27b urges it to rotate counterclockwise in FIG. 3, but the link lever 35 abuts against the engaging portion 34d of the auxiliary lever 34 to prevent the rotation. ing. This position is the assembly position, and as shown in FIG. 3, the end of the link lever 35 is located at a position deviating from the extending direction of the insertion hole 28a. Further, the base portion 34b of the auxiliary lever 34 is positioned in the extending direction of the insertion hole 28a, and the pair of engagement pieces 34c are inclined obliquely below the base portion 34b, so that the engagement portions 34d and 34d are inserted into the insertion hole 28a. The position is out of the extension direction.

  In order to assemble the shift knob 23 to the shift lever 20, first, as shown in FIG. 3, the direction of the shift knob 23 is adjusted so that the knob button 27 is located on the side of the inlet side where the hole inlet 24in of the linkage hole 24 opens. Meanwhile, the tip of the shift lever 20 is inserted into the insertion hole 28a of the shift knob 23. Next, when the tip of the pull rod 22 touches the base 34b of the auxiliary lever 34 in the shift knob 23, when the shift lever 20 is further inserted into the insertion hole 28a of the shift knob 23, as shown in FIG. Since the auxiliary lever 34 is rotated counterclockwise in the figure and the engaging portion 34d of the auxiliary lever 34 is slidably contacted on the link lever 35, the link body 33 is rotated clockwise in the figure. The distal end is inserted into the linkage hole 24, and the link lever 35 is guided and pulled into the deep portion of the linkage hole 24 by the guide wall 24 a of the linkage hole 24.

  By further pushing the shift lever 20 into the insertion hole 28a of the shift knob 23, as shown in FIG. 5, when the auxiliary lever 34 rotates counterclockwise in the figure, the engagement piece 34c is bent and deformed, and the slit 34 f expands, the link body 33 passes through the slit 34 f, and the engaging portion 34 d is detached from the link body 33.

  Then, by pushing the shift knob 23 to a predetermined position, the fixing groove 21b formed in the lever main body 21 and the locking hole 28b formed in the locking cylinder portion 28 of the shift knob 23 overlap, so that the locking hole 28b The fixing spring 14 mounted in advance is engaged with the fixing groove 21b, and the shift knob 23 is engaged with the shift lever 20 via the fixing spring 14 to be fixed.

  Finally, by pushing the knob button 27, as shown in FIG. 6, the auxiliary lever 34 released from the link body 33 is rotated to the rotating end by the tip of the pull rod 22, and the locking portion 34e provided on the base 34b. Is locked to the lock receiving portion 36 in the shift knob 23. When the locking portion 34 e is locked to the locking receiving portion 36, the state where the auxiliary lever 34 is separated from the tip of the pull rod 22 is maintained.

  With the above configuration, as shown in FIG. 6, when the operator presses the knob button 27, the knob button 27 rotates about the button pin 27 a, and the linkage pin 32 slides in the long hole portion 27 c on the side of the knob button 27. As the linkage pin 32 moves, the link body 33 rotates in the clockwise direction in the figure. As the link body 33 rotates in the clockwise direction in the figure, the link lever 35 inserted into the linkage hole 24 pulls the pull rod 22 up to the distal end T, and the detent engaging portion is separated from the detent portion, so that the shift lever 20 The movement restriction is canceled.

  As shown in FIG. 7, when the operator stops the pressing operation of the knob button 27, the knob button 27 is returned to the initial operation position by the return spring 27b, and the link body 33 rotates counterclockwise in the drawing. Thus, the pull rod 22 is returned to the position where the detent engaging portion is engaged with the detent portion by the biasing spring.

  As described above, in the present embodiment, when the tip end of the shift lever 20 is pushed into the insertion hole 28 a of the shift knob 23, the auxiliary lever 34 rotates while contacting the tip of the pull rod 22 and contacts the auxiliary lever 34. Since the link body 33 is rotated and the tip of the link lever 35 is inserted into the linkage hole 24, the operation step of mounting the shift knob 23 to the shift lever 20 is performed, and the tip of the shift lever 20 is inserted into the shift knob 23. Since it is completed in one step of pushing into the hole 28a, the assembling workability can be improved, and it is possible to prevent the occurrence of problems such as damage to parts by mistake in the assembling procedure.

  In addition, after the link lever 35 is mounted in the linkage hole 24 of the pull rod 22, the engaging portion 34 d is elastically deformed so that the link body 33 passes through the slit 34 f of the engaging portion 34 d and the engaging portion 34 d is separated from the link body 33. By separating the auxiliary lever 34 from the pull rod 22, the link lever is not affected by the auxiliary lever 34 when the pull button 22 is moved up and down by pressing the knob button 27. 33 is operated reliably.

  Further, after the link lever 35 is mounted in the linkage hole 24 of the pull rod 22, when the auxiliary lever 34 is rotated to the rotating end by the tip of the pull rod 22, the locking provided in the vicinity of the shaft support portion 34 a of the auxiliary lever 34. Since the portion 34e is locked to the locking receiving portion 36 in the shift knob 23, the state where the auxiliary lever 34 is separated from the tip of the pull rod 22 can be reliably held.
