The purpose of the present invention is to facilitate and achieve high precision in adjusting the centering of an optical fiber with respect to an illumination optic system. The present invention is an optical fiber scanner (10) comprising: an illumination light optical fiber (11) an annular elastic body (21) that is formed from an elastic material and has a fitting hole (21a) into which the side of the illumination light optical fiber (11) proximal of the distal end thereof is fitted and a plurality of piezoelectric elements (23) that are secured to the annular elastic body (21), are polarized in a radial direction of the illumination light optical fiber (11), and cause the illumination light optical fiber (11) to vibrate when an alternating voltage is applied thereto in the polarization direction. The annular elastic body (21) includes: a vibration transmission part (27) which has side faces on which the plurality of piezoelectric elements (23) are attached and transmits the vibrations of the piezoelectric elements (23) to the illumination light optical fiber (11) and a fiber support part (29) that is integrally molded with the vibration transmission part (27) and is capable of cantilevering the illumination light optical fiber (11) at a position spaced apart from the side of the vibration transmission part (27) proximal of the piezoelectric elements (23).La présente invention a pour but de faciliter et dobtenir un ajustement extrêmement précis du centrage dune fibre optique par rapport à un système optique déclairage. La présente invention concerne un dispositif de balayage à fibre optique (10) qui comporte : une fibre optique de lumière déclairage (11) un corps élastique annulaire (21), qui est formé dun matériau élastique et qui présente un trou dajustage (21a) dans lequel est ajusté le côté proximal, par rapport à son extrémité distale, de la fibre optique de lumière déclairage (11) une pluralité déléments piézoélectriques (23), qui sont fixés au corps élast
