Abstract
A linear drive device includes an output shaft having a first spiral groove, a movable body engaged with the first spiral groove so as to move in an axial direction, a first fixed shaft extending along an axial line, and a second fixed shaft extending around the axial line. The movable body includes a moved member engaging with the first spiral groove, and a slider moving in the axial line direction integrally with a moved member. The slider is provided with guide holes in which the first fixed shaft penetrates, a penetration part in which the second fixed shaft penetrates with play in the direction in which the first and second fixed shafts are connected, and a first and second receiving part for receiving a moved member when the moved member was rotated to one side along the axial line and when the moved member rotated to the other side.
