Problems solved by technology
[0007] However, the above-mentioned other conventional shift lever mechanism 2000 cannot change the positions of the pivot centers B and C, and various components for setting such pivot centers B and C are required.
[0008] and, if Figure 11 As shown, since the shift lever 2001 is connected to the shaft 2002 via a holder 2003 having a spherical connecting portion 2004, a certain gap may be generated during the connection process of the shift lever 2001 and the connecting portion 2004.
[0009] Moreover, since the shift lever 2001 and the connecting portion 2004 are connected in the form of a ball joint, there is a problem that the operating force of the shift lever 2001 cannot be effectively transmitted to the shaft 2002.

The present invention relates to a gearshift device for transmitting a gear shifting operation to a driving gear assembly, and can provide a gearshift device comprising: a shaft of which one end is connected to one end of the gearshift so as to enable rectilinear movement along the axial direction and rotation along the circumferential direction according to the gear shifting operation; a shift arm of which one end is connected to the other end of the shaft so as to enable rectilinear movement and rotation corresponding to each of the rectilinear movement and rotation of the shaft, and of which the other end is selectively coupled to a first shift rail and a second shift rail connected to the driving gear assembly; a shaft holder fixed to a vehicle body, slidably accommodating the shaft, and restricting the position of the shaft; and a holder bracket coupled so as to be slidable in the circumferential direction of the shaft at the outer periphery of the shaft holder, and a connection rod respectively hinge-coupled to the middle portion of the gearshift at both ends thereof.
Description
technical field [0001] The present invention relates to a shift lever mechanism that transmits a shift operation of an agricultural machinery vehicle such as a tractor to a transmission, and more particularly, to a shift lever mechanism capable of performing a plurality of shift operations through one shift lever. Background technique [0002] An agricultural machine such as a tractor transmits rotational force generated by an engine to driving wheels through a transmission, and an operator operates the transmission using a shift lever (lever) provided on a driver's seat, whereby the power generated by the engine is adjusted to meet driving conditions. The rotational speed and torque are transmitted to the drive wheels. [0003] For example, if Figure 9 As shown, in the conventional shift lever mechanism 1000 disclosed in Korean Patent Publication No. 10-1512226, the shift lever 1001 pivots A around the pivot portion 1004, so that the end of the shift lever 1001 is in conta...
