Claims

[Scope of utility model registration request]

A cylinder device that obtains thrust by fluid pressure applied to a piston slidably positioned within a cylinder tube, the cylinder device being axially fixed within a closing member provided at an end of the cylinder tube,
a cylindrical body that holds a radially movable sphere within a wall surface;
A lock rod is fixed to the side of the piston facing the closing member, and has a groove carved in its outer circumference to be engaged with the sphere when it is freely inserted into the cylindrical body, and a shaft is provided inside the closing member. a lock cylinder formed in the direction of the cylinder body and communicating with a fluid chamber on the closing member side in the cylinder tube through the cylinder body; A cylinder device comprising: a lock piston having a hole of different diameter into which the end of the cylinder is inserted; and an elastic member urging the lock piston toward the cylinder.
