Claims

[Scope of utility model registration request]

(1) A distance adjustment ring and a locking position setting ring are rotatably fitted into the fixed lens barrel of the lens, a click groove is formed in one of the distance adjustment ring and the locking position setting ring, and a click groove is formed in the other. Supports the click member that is biased to move toward the click groove,
Furthermore, in the presetting mechanism of the distance adjustment ring of the lens barrel, which is provided with a fixing means for fixing the locking position setting ring at an arbitrary position with respect to the fixed barrel, a spring means for biasing the click member to move toward the click groove side is provided. A preset mechanism for a distance adjustment ring of a lens barrel, characterized in that a click stop force adjustment means for adjusting a biasing force is provided.

(2) Utility model registration In claim 1, the click stop force adjusting means has a spring seat of a compression spring that biases the click member to move, and the spring seat moves toward and away from the click member side. A presetting mechanism for a distance adjustment ring of a lens barrel, comprising a compression spring force adjustment member whose movement can be adjusted.

(3) In claim 2 of the utility model registration claim, a click stop mechanism is provided between the compression spring force adjusting member and the annular member that supports it, for regulating the movement position of the click stop force adjusting member in multiple stages. A preset mechanism for the distance adjustment ring on the lens barrel.
