Provided is an operation input device (2) including a base member (21); a grip (26) that is gripped by an operator and that is moved relative to the base member (21); a coupling portion (23) that couples the grip (26) to the base portion (21) in a pivotable manner; and a scaling-ratio changing mechanism (24) that changes an amount by which the grip (26) is moved with respect to a pivoting angle of the coupling portion (23), and an object thereof is to enable switching operation between a coarse movement and a fine movement by using the same operation. |
