A plurality of operating side link members (107,108) corresponding to a plurality of working side link members (102,102) of a working device (101) are provided in a device (106) for operating working equipment. Rotation of the working side link members is detected by means of a rotation sensor (105). A motor (109) is driven in response to a signal from the rotation sensor (105). A differential detecting portion (114) has a working side movable portion (110) driven both in a forward direction and a reverse direction by the motor (109), an operating side movable portion (112) that is shiftable both in the forward direction and the reverse direction within a predetermined range from a neutral position to said working side movable portion, and a differential sensor (113) for detecting a relative shift from the neutral position of the operating side movable portion to the working side movable portion. An operation transmitting means (111) is disposed between the operating side link members (107,108) and the operating side movable portion (112) for mechanically transmitting the rotation of the operating side link members (107,108) and for shifting the operating side movable portion (112) in response to the rotation of the operating side link members. The driving device (104) is controlled by means of a control section (115) in response to the signals from the differential sensor (113). <IMAGE> |
