ある。Means and operation for solving the problem A spacer is provided between the head side of the cylinder tube and the rod head, with the outer cylinder screwed onto the inner cylinder and fixed with a lock nut, so that the stroke end position on the contraction side can be easily adjusted. This allows for changes and adjustments.

向している。Embodiment The spacer 5 is constructed by screwing an inner cylinder 11 onto an outer cylinder 10 and fixing it with a lock nut 12. The spacer 5 is provided between the head side 1b of the cylinder tube 1 and the rod head 4, and the inner cylinder 11 is attached to the piston rod 3. The cylinder tube 1 is fitted into a portion projecting outward from the head side 1b so as to be movable in the axial direction and faces the rotary head 4, and the outer cylinder 10 faces the head side 1b.

期に摩耗したり、ロツドヘツド４の向きが変化し
ない。 Loosening the lock nut 12 tightens the inner cylinder 11 and outer cylinder 10, and loosening the lock nut 12 tightens the inner cylinder 1.
1 and the total length of the outer cylinder 10, that is, the length L of the spacer 5
Since the piston rod 3 can be adjusted, the contraction side stroke end position can be easily changed and adjusted without removing the rod head 4.
The piston 2 does not rotate, the seal of the piston 2 does not wear out prematurely, and the direction of the rod head 4 does not change.
考案の効果
ロツクナツト１２を弛めて外筒１０と内筒１１
を締付け、弛めることでスペーサ５の長さを変更
でき、ロツドヘツド４を取り外しせずに簡単に縮
少側ストロークエンド位置を変更調整できる。Effects of the idea: Loosen the lock nut 12 and remove the outer cylinder 10 and inner cylinder 11.
By tightening and loosening, the length of the spacer 5 can be changed, and the contraction side stroke end position can be easily changed and adjusted without removing the rod head 4.
また、ピストンロツド３の回りに内筒１１と外
筒１０を回転すれば良いから、調整時にピストン
ロツド３、ロツドヘツド４を回転しなくとも良
く、ピストン２のシールが早期に摩耗することが
ないし、ロツドヘツド４の向きが変化せずにシリ
ンダ装置を取付けた状態において縮少側ストロー
クエンド位置を変更調整できる。 In addition, since the inner cylinder 11 and the outer cylinder 10 only need to be rotated around the piston rod 3, there is no need to rotate the piston rod 3 and the rod head 4 during adjustment. The contraction side stroke end position can be changed and adjusted with the cylinder device installed without changing the direction of the cylinder.
また、ピストンロツド３に内筒１１に嵌合すれ
ば良く、ピストンロツド３に内筒取付用のネジ部
が不要であるから、ピストンロツド３を必要以上
に長くしなくとも良いのでシリンダ装置の全長が
長くならずに取付寸法をコンパクトにできるし、
通常のシリンダ装置をそのまま流用して縮少側ス
トロークエンド位置を変更できるシリンダ装置と
することができる。 In addition, since the piston rod 3 only needs to be fitted into the inner cylinder 11, and there is no need for a threaded part to attach the inner cylinder to the piston rod 3, there is no need to make the piston rod 3 longer than necessary, so if the overall length of the cylinder device is long. The installation dimensions can be made compact without
It is possible to use a normal cylinder device as it is to provide a cylinder device that can change the stroke end position on the contraction side.
