To provide a work machine capable of securing stable slip torque.SOLUTION: A work machine includes a motor, a rotation shaft that rotates by the power of the motor, and a torque limiter for transmitting the power of the rotation shaft to a driven part. The torque limiter includes a first transmission body and a second transmission body that rotate integrally with the rotation shaft, and an output member disposed between the first transmission body and the second transmission body in contact with them for outputting the power to the driven part by rotating integrally with the first transmission body and the second transmission body, and rotating relatively with the first transmission body and the second transmission body when the torque equal to or more than a set torque acts. The output member includes at least one grease hole for storing grease for causing the grease to adhere to a contact face that comes in contact with the first transmission body and the second transmission body.SELECTED DRAWING: Figure 9【課題】安定した滑りトルクを確保することができる作業機を提供する。【解決手段】作業機は、原動機と、原動機の動力によって回転する回転軸と、回転軸の動力を被動部に伝達するトルクリミッタと、を備え、トルクリミッタは、回転軸と一体回転する第１伝動体及び第２伝動体と、第１伝動体と第２伝動体との間に当接して配置されていて、第１伝動体及び第２伝動体と一体回転することで被動部へ動力を出力すると共に設定トルク以上のトルクが作用した際に第１伝動体及び第２伝動体と相対回転する出力部材とを有し、出力部材は、第１伝動体及び第２伝動体に当接する当接面にグリスを付着させるべく該グリスを貯留する少なくとも１つのグリス穴を有する。【選択図】図９
