業機用ゲージ輪装置。[Claims for Utility Model Registration] The system includes a vertical support shaft 21 attached to a working machine 12 and a stay 23 that holds a gauge wheel 22 rotatably around its axis, and the gauge wheel 22 swings in the left-right direction. The cylindrical body 24 at the top of the stay 23
In the gauge wheel device for a work machine, in which the gauge wheel is rotatably fitted onto the support shaft 21, a lower spring receiver 27 is attached to the upper end of the cylindrical body 24 of the stay 23.
is fixed to the support shaft 21 so as to be rotatably fitted on the outside, and an upper spring receiver 28 is externally fitted and fixed above the lower spring receiver 27 of the support shaft 21 so as to face the lower spring receiver 27. A coil spring 29 is fitted between the spring receivers 27 and 28 of 21, and the spring receivers 27 and 28
Cover bodies 30 and 31 are respectively protruded to partially cover the outer periphery of the coil spring 29 and restrict the range of rotation of the cylinder body 24 with respect to the support shaft 21, thereby swinging the gauge wheel 22 outward in the left and right direction. In order to urge the cylindrical body 24 against the support shaft 21 as shown in FIG.
, 31, respectively.
