の摺動に支障をきたしていた。 Conventionally, a horizontal pivot rod that is connected to a main gear shift lever of a tractor and pivotally supports an engagement pin that engages with a shift block has been left exposed without being protected from the outside. As a result, soil and sand adhere to the horizontal beams,
This was causing problems in the expansion and contraction of the spring attached to the horizontal rod and in the sliding movement of the horizontal rod.

ある。 In this invention, a horizontal pivot rod is connected to the main gear shift lever via a mounting rod and a mounting member, and four telescoping bell-shaped boots are covered to surround the horizontal rod, and air is removed from each of them. By providing a hole structure, when the main gear shift lever is operated in the lateral direction, the pivot horizontal rod moves left and right, and as it slides, the air inside the sealed bellows-like boot increases the volume of the bellows-like boot. The air vent hole structure of the bellows boot attached to the horizontal pivot rod is configured so that air flows out or flows in through the air vent hole in response to changes in the air, so that it does not interfere with the sliding movement of the horizontal pivot beam. This is what we intend to provide.

に摺動する。 The embodiment of the present invention is constructed as described above, and when the main shift lever 10 is operated, the pivot rod 13 slides left and right via the mounting rod 11 and the mounting member 12. When the co-supporting transverse rod 13 slides to the left, the bellows-like boots 19 and 2
0 is fixed at both ends to the tube body 21 and the pivot tube body 18, or to the boss member 15 and the pivot tube body 18', so that the bellows-shaped boots 19 and 20 are extended, The volume inside the bellows-like boots 19 and 20 becomes larger. Therefore,
Air flows into the bellows-like boots 19 and 20 through the air vent structures 19- and 20-, and the air pressure inside the bellows-like boots 19, 20 is maintained at the same pressure as atmospheric pressure.
Even if the volume increases, the pivot horizontal rod 13 can slide left and right without any problem.

The air leaks out and it contracts, folding up and reducing its volume. At this time, the air inside the bellows-like boots 19' and 20' flows out smoothly through the air vent structures 19'- and 20'-, so the sliding of the horizontal pivot rod 13 can be performed without any hindrance. It's something you get.

ない得る。 On the other hand, when sliding the horizontal pivot rod 13 to the right,
The bellows boots 19 and 20 contract and the bellows boots 19' and 20' extend. At this time, air flows out from the air vent structures 19- and 20-, and air flows in from the air vent structures 19'- and 20'-, so that the bellows-like boots 19, 20 and 19', 20- ' can be smoothly extended and contracted, and the pivot horizontal rod 13 can slide without any problem.
