COMPOUND OPERATION DEVICE

PROBLEM TO BE SOLVED: To provide a compound operation device capable of shortening a total necessary dimension in a slide direction.SOLUTION: A compound operation device includes: a base (10); a slider (30); an operation member (50); detection elements (61, 62) which detect a state that the operation member is slid; and transmission members (71, 72) which transmit an operation force acting on the slider to the detection elements. The base includes transmission member holding parts (25, 26) which hold the transmission members so that displacement of the slider in the slide direction is converted to displacement in a direction arranged parallel to rotation shafts of the transmission members. The slider has transmission member pressing parts (39, 40) which press the transmission members in the slide direction. Each transmission member includes: a pressed part (71a) which is pressed by the slider; and an element pressing part (71b) which presses the detection element in an element pressing direction. Each detection element is fixed to the base in a posture such that the detection element may detect the displacement of the element pressing part in the element pressing direction.
