A handheld power working machine includes a main body (100) including a driving part, a working part (120) that drives by the driving part provided in the main body (100), and a gripper (201) provided to be able to rotate with respect to the main body (100). The gripper (201) includes a restriction part (250) that can switch between at least a restriction state where the gripper (201) is restricted from rotating with respect to the main body (100) and a release state where the gripper (201) can rotate by releasing the restriction state, and switching operation parts (240L, 240R) configured to perform switching operation to switch between the restriction state and the release state in the restriction part (250). Respective switching operation parts (240L, 240R) are disposed in at least one side and the other side of the gripper (201) in a direction in which the gripper (201) rotates.
