, Embodiments and operations Next, embodiments of the present invention will be explained based on the drawings. 1st
The gear diagram is shown as an example in the figure, but 1. The output of the engine (1) is transmitted through the main clutch (2) and the gear train (3) to the first output shaft (4) of the first transmission mechanism U, and the rotation of the first output shaft (4) is controlled. The forward/reverse switching mechanism (B) transmits the rotation of the forward/reverse output shaft (5) in the forward or reverse direction, and transfers the rotation of the forward/reverse output shaft (5) to the second transmission mechanism (8).
1 to the second output shaft (6), or the rotation of the forward/reverse output shaft (5) is sufficiently decelerated by the ultra-low speed reduction mechanism 0 and transmitted to the second output shaft (6), and the gear train (7) The drive pinion shaft (ms, s) is driven through the differential mechanism (9)
It drives the left and right rear wheels Ql (II.
A gear α3.13.11αQ which freely rotates on υ is connected to a gear +11. +lη, (IS, α9
, so that four types of gear change outputs are output to the first output shaft (4) by operating the operating member Qη to neutral (toward) or forward or backward, respectively. When Qυ is moved to the two-dot chain line, the large diameter gear Q!9
When the output shaft (4) is in the 4th speed position (H4) where it rotates at the highest speed due to the meshing of the small diameter gear A scratch and when the operating member QTJ is moved to the dotted line position, the meshing of the gear I%α As a result, the first output shaft (4) is at the third speed position (horse), which is lower than the above-mentioned high speed. The illustrated forward/reverse switching mechanism (Bl is a gear (c) that freely rotates on the forward/reverse output shaft (5)
, (Incorporated) is one that meshes with gear a9 through the gear shaft or idle gear (c), when the operating member moves to the dotted line position, the gear +18. The meshing of (c) causes the forward/reverse output shaft (5) to rotate in the reverse direction (reverse position ■), and when the operating member (c) is moved to the dashed-dotted line position, the gears (19, (c), (towards ), the forward/reverse output shaft (5) rotates in the forward direction to the forward position [F]. goods), (2) is the forward and reverse output shaft (5
), or the gear (to) that freely rotates on the second output shaft (6), and when the operating member C11l is moved to the dashed-dotted line position, it engages with the forward/reverse output shaft (5). The second output shaft (6) is directly connected to the high speed position 0,
When the operating member 011 is moved to the dotted line position, the rotation of the forward/reverse output shaft (5) is between gear (5) and gear (2) (to).
The low speed position υ is achieved by the meshing of the two. In the illustrated ultra-low speed reduction mechanism C), by moving the operating member (to) to the right in FIG. When the operating member 04 is operated to the left in FIG. 1, the rotation of the forward/reverse output shaft (5) is
Gear (2), (2), gear (to), (to), and gear (
9), (to) and gear (to), (a), the speed is reduced to an extremely low speed, and the VC is transmitted to the second output shaft (6). A detection unit that detects that the transmission mechanism is in a high-speed state where reverse travel should be prevented (the one illustrated as Kotobuki is a detection unit in which the operating member Qυ of the first transmission mechanism (transmission) is in the third gear position (H3) K A switch (Sρ) that closes its contact (Sl,) when the operating member 09 is in the 4th gear position (H4)
S2) are connected to the power source [F] in parallel with each other, and when the operating member ON of the second transmission mechanism (S) is in the high speed position 0, a switch (S3) that closes its contact (S3ρ), It is connected in series to switches (Sl) and (S2),
The detection unit (T1) operates when the contact (S3a) of the switch (S,) or (S2) and the switch (S3) closes, and the detection unit (Tρ) operates. By energizing the electric actuating part (A,) 11 such as an electromagnetic solenoid as illustrated in FIG. 2, the actuating body (a) is provided so as to project in the direction of the arrow,
The check member (the peak of the check member CD) projects in the arrow direction in conjunction with the above-mentioned projecting operation of the actuating member (a), and in the non-projecting state, the operating member (a) of the second transmission mechanism (5) moves forward. It can be operated to any number of position -D, neutral position axis and reverse position (■), but if the restraint member (dl) is in the protruding state, the 7 operating member CIIt in the reverse position (■) will be pushed to the neutral position (■). Therefore, if the check member (dl) is in the protruding state, the operating member @ is moved from the forward position (F) or the neutral position to the reverse position.
Even if the user does not operate the actuator (a), the movement to the reverse position 4 is prevented by the check member (di). The movement of the actuating body (a) in the arrow direction causes the restraint member (d) to move in the arrow direction against the spring (c).
