FIXING STRUCTURE FOR REPLACEMENT PART IN WORK MACHINE, AND LOCKING MEMBER FOR FIXING STRUCTURE
To provide a fixing structure for a replacement part in a work machine, which allows a locking member to be reused and enables easy determination of engagement of the locking member, and a locking member.SOLUTION: A fixing structure includes an attachment portion, a pin member, and a locking member. A replacement part is attached to the attachment portion. The attachment portion includes a pin hole. The pin member is disposed in the pin hole. The locking member engages with the pin member and prevents the pin member from coming off. The locking member includes an opening, a groove portion, a retaining portion, and a resistance portion. The groove portion extends from the opening and engages with the pin member. The retaining portion is provided in the groove portion and holds the pin member so that it does not come off. The resistance portion is provided in the groove portion between the opening and the retaining portion. The resistance portion comes into contact with the pin member when engaged with the pin member to give a feeling of resistance.SELECTED DRAWING: Figure 8
【課題】ロック部材の再利用が可能であると共に、ロック部材の係合を容易に判断することができる作業機械における交換部品の固定構造、及び、ロック部材を提供する。【解決手段】固定構造は、取付部と、ピン部材と、ロック部材とを備える。交換部品は、取付部に取り付けられる。取付部は、ピン孔を含む。ピン部材は、ピン孔に配置される。ロック部材は、ピン部材に係合し、ピン部材を抜け止めする。ロック部材は、開口と、溝部と、保持部と、抵抗部とを含む。溝部は、開口から延びており、ピン部材に係合する。保持部は、溝部に設けられ、ピン部材が抜けないように保持する。抵抗部は、溝部において開口と保持部との間に設けられる。抵抗部は、ピン部材への係合時にピン部材に接触して手応えを与える。【選択図】図８
