Abstract
In an electric cylinder device including a third gear that rotates by receiving rotation of an electric motor and a linear motion conversion mechanism that converts the rotation of the third gear into linear motion of a piston inside a cylinder, a nut, which is a linear motion portion of the linear motion conversion mechanism, and the piston are connected in a state in which relative displacement in a radial direction is allowed.
Claims5
An electric cylinder device comprising:
- a piston disposed inside a cylinder;
- a rotation input component that rotates by receiving rotation of an electric motor;
- a linear motion conversion mechanism that includes a rotation portion that is rotated due to transmission of the rotation of the rotation input component and a linear motion portion that acts on linear motion of the piston by linearly moving according to the rotation of the rotation portion;
- and
- a housing in which the cylinder is provided and in which the piston, the rotation input component, and the linear motion conversion mechanism are accommodated, wherein
- a first component and a second component, which are two components among components of the electric cylinder device, are allowed to undergo relative displacement in a radial direction that is a direction orthogonal to an axial direction of the piston, and
- the first component is a component that relatively displaces the piston with respect to the cylinder in the radial direction according to relative displacement with respect to the second component in the radial direction.
