Abstract: An arm-type assistance device includes a pillar, a first support portion, a first arm, a second support portion, a second arm, a third arm, an operating unit, and a cargo holding unit. The first arm includes a first member, a first air cylinder, and a second member. The first support portion, the first member, the second support portion, and the second member form a parallel linkage. The parallel linkage is assisted by the first air cylinder. The arm-type assistance device further includes a controller that is configured to control pressure of first air cylinder. The third arm includes a second air cylinder. The controller controls pressure of the second air cylinder. A dimension in an axial direction of the second arm is greater than a dimension in an axial direction of the first arm.
