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. In a preset mechanism for a distance adjustment ring of a lens barrel, which supports the click member biased to move toward the click groove side, and further includes a fixing means for fixing the locking position setting ring at an arbitrary position with respect to the fixed barrel. , click groove above,
A click stop force adjustment member is supported on the annular member which is to be provided with the click stop force adjustment member so as to be movable in the front and back direction, and the click stop force adjustment member is engaged with the click stop force adjustment member at different positions in the front and rear direction with different engagement forces from the click member. A preset mechanism for a distance adjustment ring of a lens barrel, characterized by forming a plurality of click grooves that can be combined.

(2) Scope of Utility Model Registration Claims Paragraph 1: 1. A click stop mechanism is provided between the click stop force adjustment member and the annular member supporting the click stop force adjustment member to hold the click stop force adjustment member in a position where each of the click grooves can engage with the click member. Preset mechanism for lens barrel distance adjustment.
