Abstract
The fastening structure is fastening one member and another member via a fastening member, and includes: a fitting portion having a fitting hole; a to-be-fitted portion having a to-be-fitted hole; and the fastening member inserted into the fitting hole. The fastening member has: a trunk portion, between one end and another end of the fastening member; a tool groove at the one end; a come-off prevention portion at the other end, the come-off prevention portion having a greater radius than a radius; and a helical protrusion at a part of the trunk portion. The fitting portion has a helical groove configured to be screwed with the helical protrusion. A radius of the fitting hole is less than the radius of the come-off prevention portion, and a radius of the to-be-fitted hole is not less than the radius of the come-off prevention portion.
