Abstract
A stress treatment device has an operating unit including a head unit performing peening by irradiating an inside of a hole formed in a structure with laser to form a compressive stress region in the hole; a laser unit having an optical fiber guiding the laser to the head unit; a jetting unit jetting liquid into the hole; and a support part supporting the optical fiber in a manner of allowing the jetted liquid to flow through and being fixed in the head unit.
