A spherical portion 40b formed at the lower end of the operating lever 40 is fitted in a through hole 20a formed in the main shaft 20. Further, a knob 28 is attached to the upper part of the operation lever 40.

The operation shaft 22 is integrally formed so as to project downward in the middle portion of the outer cylinder 21, and is arranged on the axis of the operation lever 40. The spherical portion 22a formed at the lower end of the operating shaft 22 is fitted in the piece member 31 of the switch unit 30 as the switch operating means.

The switch unit 30 is provided with a select slide member 32 and a shift slide member 33 that slide in the select direction and the shift direction via a piece member 31, respectively. Correspondingly, magnet switches 34 and 35 are arranged respectively. Then, the operations of the operation lever 40 in the select direction and the shift direction are detected by the magnet switches 34 and 35 via the operation shaft 22, and the select signal and the shift signal for designating the gear stage of the transmission are set to be output. Has been done.

The operation pattern forming member 50 is provided on the outer cylinder 21 so as to project to the front F side orthogonal to the axis and is wound around the outer cylinder 21 between the operation pattern forming member 50 and the housing 10. It is biased in the direction of arrow A (see FIGS. 1 and 3) by a compression spring 51 as a select position holding means.

Further, the operation lever 40 is biased by the neutral position holding means 80 in the direction of returning the operation lever 40 to the neutral position when the operation lever 40 is tilted in the shift direction. The neutral position holding means 80 includes a support roller 81, a holding spring 82, and a spring stopper 83. The support roller 81 is rotated by a support pin 84 projecting on the rear cylinder side of the outer cylinder 21 at a right angle to the axis. It is installed freely. The holding spring 82 is a torsion coil spring, and a base 82a is wound around a mounting shaft 85 projecting from the housing 10. Free ends 82b and 82c formed in a bifurcated shape and parallel to each other are used as a support roller 81. Being pressed against. The spring stopper 83 is provided so as to project from the housing 10, and the free ends 82b and 82c of the holding spring 80 are in contact with the upper surface 83a and the lower surface 83b of the spring stopper 83, respectively.

The regulation member 60 is composed of an upper regulation member 61 and a lower regulation member 62, and is provided so as to protrude from the housing 10. Each of the regulating members 61 and 62 has the same shape, and is composed of horizontal portions 61a and 62a that are arranged to face each other, and upright portions 61b and 62b that are bent downward at right angles to the horizontal portions 61a and 62a. As shown in FIGS. 1 and 3, in the state where the operation lever 40 is held at the neutral position, the operation pattern forming member 50 can pass in the direction of the arrow B, and the upright portions 61b of the restricting members 61 and 62. , 62b are set so that they can pass outside. Further, when the operation pattern forming member 50 moves between the restriction members 61, 62, it is set to be movable only in the reverse shift direction, that is, in the direction of arrow C.

The detent mechanism 70 is a cylindrical tubular body 71 fixed to the housing 10 and disposed in an intermediate portion between the upper and lower regulating members 61 and 62, and a compression spring 72 housed in the tubular body 71. The reverse lock pin 73 is biased outward by The reverse lock pin 73 is set so as to be fitted into the lock hole 50a formed in the operation pattern forming member 50 when the operation lever 40 is shifted to the reverse shift position.

Further, the operating lever 40 is elastically provided with a rod 41 for projecting to both sides thereof so as to provide a feeling of moderation of up-down shift, and is made to oppose both ends of the rod 41. The moderation forming plates 42 and 43 are respectively arranged on the housing 10.

The rod 41 is slidably fitted into a U-shaped bracket 44 fixed to the socket 23 and to a collar 45 fixed in a direction perpendicular to the main shaft 20. Washers 46 are fixed to both ends of the rod 41, and a compression spring 47 is wound around a collar 45 between each washer 46 and the bracket 44. A spherical surface portion 41a is formed on both ends of the rod 41.

The moderation feeling forming plates 42 and 43 are respectively fixed to the housing 10. When the operation lever 40 is shifted to the upshift position and the downshift position, the moderation feeling forming plates 42 and 43 are Detent grooves 42a and 43a into which the spherical surface portion 41a of the rod 41 is fitted are formed, respectively.

Next, the operation of the embodiment of the present invention will be described.

As shown in FIG. 3, the normal outer cylinder 21 is normally biased by a compression spring 51 so that the bush 24 on the right side of the outer cylinder 21 is pressed against the housing 10. At this position, the operating lever 40 holds the holding spring. 82 holds the neutral position, so-called hold position H (see shift select pattern 90 shown in FIG. 8). In this hold position H, the operation pattern forming member 50 is arranged outside the upper and lower restricting members 61 and 62, so that the operating lever 40 is tilted in the directions D and E (see FIGS. 2 and 6). be able to.

When the operating lever 40 is tilted in the direction of arrow D, that is, in the upshift direction with the spherical portion 40b as the center, the holding spring 82 is first bent, and thereby an initial operating force is generated in the operating lever 40.

Further, when the operating lever 82 is tilted, the spherical surface portion 41 a of the rod 41 abuts against the moderation-sensing forming plate 42 to bend the compression spring 47, thereby sequentially changing the operating force of the operating lever 40. You can Then, when the spherical surface portion 41a of the rod 41 reaches the position facing the groove 42a of the moderation forming plate 42, the spherical surface portion 41a is fitted into the groove 42a by the spring force of the compression spring 47, and the operating lever 4 is inserted. 0 reaches the upshift position U (see FIG. 8).

When the hand is released from this state, the operation lever 40 returns to the hold position H by the restoring force of the holding spring 82.

When the operating lever 40 is tilted in the direction of arrow E, that is, in the downshift direction, the spherical surface portion 41 a is fitted into the groove 43 a of the moderation feeling forming plate 43 by the same procedure as in the upshift, and the operating lever 40 is moved. Reaches the downshift position D (see FIG. 8).

In order to reverse shift the operating lever 40 in the hold position H, the operating lever 40 resists the spring force of the compression spring 51, and the bush 24 on the left side of the outer cylinder 21 around the spherical portion 40b (see FIG. 3) is tilted in the direction of arrow F until it comes into contact with the housing 10, the operating lever 40 reaches a neutral position in the reverse shift direction, a so-called neutral position N (see FIG. 8), and the compression spring 51 bends. Mu. At the same time, the reverse lock pin 73 contacts the operation pattern forming member 50 to bend the compression spring 72. In this way, the bending of the compression springs 51 and 72 makes it possible to generate an initial operation force on the operation lever 40.

At the neutral position N, the operation pattern forming member 50 is arranged between the horizontal portions 61 a and 62 a of the upper and lower restricting members 61 and 62. Therefore, the tilt of the operation lever 40 in the arrow D direction is restricted by the operation pattern forming member 50 contacting the horizontal portion 62a of the lower restriction member 62, and the operation lever 40 tilts in the arrow E direction by a predetermined angle. Is set to.

When the operation lever 40 in the neutral position N is tilted in the direction of arrow E, that is, in the reverse shift direction, and when the lock hole 50 a of the operation pattern forming member 50 reaches the position facing the reverse lock pin 73, the lock lever 50 is reversed in the lock hole 50 a. The lock pin 73 is fitted and the operating lever 40 is held at the reverse shift position R (see FIG. 8).

From this state, the operation lever 40 is tilted in the reverse reverse shift direction (direction of arrow D in FIG. 2), the reverse lock pin 73 is disengaged from the lock hole 50a, and then the hand is released. The restoring force of 72 causes the operating lever 40 to return to the hold position H.

As described above, the operation of the operation lever 40 in the select direction, that is, the operation between the hold position H and the neutral position N is a position where the operation pattern forming member 50 can pass between the upper and lower restricting members 61 and 62. The operation of the operation lever 40 in the up-down shift direction is performed at a position where the operation pattern forming member 50 can pass outside the upper and lower restricting members 61 and 62. Further, the operation of the operation lever 40 in the reverse shift direction is performed between the upper and lower restricting members 61 and 62 by the operation pattern forming member 50 and between the restricting members 61 and 62.

As described above, the operation of the operation lever 40 in the shift select direction can be restricted by the cooperation of the operation pattern forming member 50 and the upper and lower restricting members 61 and 62. Therefore, the conventional guide plate 1 is not required, and problems in strength and weight can be solved, and strength and weight can be reduced.
