To provide an article installation device to a rod body in which an article can be used in favorable usage feel regardless of a build of a user of the article or other conditions.
This device is provided with a clamp member 1 which has a roughly C-shaped cross sectional surface opened on one side in a circumferential direction, and which can be elastically deformed in a diametric direction to be engaged to the outer circumferential side of a rod body 7 having a specified diameter from the opened side for holding the rod body 7 by elastic restoration force of it, and an article holding member 3 provided on the clamp member 1 and having a holding function to an article 8. An installation position and attitude of the clamp member 1 to the rod body 7 are held by elastic restoration force of the clamp member 1. By applying operation force exceeding friction force applied between the clamp member 1 and the rod body 7 to the clamp member 1, the clamp member 1 moves in an action direction of the operation force to change a relative position of the article 8 to the rod body in a rotation direction or axial direction, so the article 8 is disposed at the optimum position suitable to the physique of a user, his using attitude, etc., to maintain favorable usage feel.
