WORK MACHINE, AND BUFFER MECHANISM FOR CONTROLLING GEAR
PROBLEM TO BE SOLVED: To provide a work machine and a buffer mechanism for a controlling gear that mitigate an impact when the controlling gear is lowered, the controlling gear being installed beside a driver seat and rotatable in an upward direction.SOLUTION: A work machine includes a driver seat, a controlling gear with a controlling lever, a work device controlled by the controlling lever, a support mechanism supporting the controlling gear rotatably between a first position beside the driver seat and a second position above the first position, and a buffer mechanism mitigating an impact when the controlling gear is rotated from the second position toward the first position. The buffer mechanism for the controlling gear is the buffer mechanism for the controlling gear with the controlling lever and is supported rotatably between the first position beside the driver seat and the second position above the first position, and includes a resistance provision part that provides resistance against rotation from the second position toward the first position.SELECTED DRAWING: Figure 11
【課題】操縦装置を運転席の側方に設けるとともに当該操縦装置を上方に向けて回動可能とした場合に、操縦装置を下降させたときの衝撃を緩和することができる作業機、及び操縦装置の緩衝機構を提供する。【解決手段】作業機は、運転席と、操縦レバーを有する操縦装置と、操縦レバーにより操作される作業装置と、操縦装置を運転席の側方である第１位置と、第１位置よりも上方である第２位置とに回動可能に支持する支持機構と、操縦装置を第２位置から第１位置に回動させたときの衝撃を緩和する緩衝機構とを備えている。操縦装置の緩衝機構は、操縦レバーを有し、運転席の側方である第１位置と、第１位置よりも上方である第２位置とに回動可能に支持された操縦装置の緩衝機構であって、第２位置から第１位置への回動に抵抗を付与する抵抗付与部を有する。【選択図】図１１
