Wire locking structure for boom extension
A boom-extending wire locking structure has a wire locking tool, provided at a base end side of a first boom member and/or a base end side of a third boom member, that locks an extending wire by winding a lock part of each wire member. The wire locking tool includes: a pair of fixing pieces provided on both sides in an orthogonal direction orthogonal to a boom-extending direction and fixed to the first boom member and/or the third boom member; and wire locking parts, provided between the pair of fixing pieces, including arch-shaped grooves for winding the respective lock parts of the wire members. The wire locking parts are arranged in a central axis direction of the arc shape between the pair of fixing pieces. Central axes of the wire locking parts are arranged at different positions in the orthogonal direction from respective adjacent wire locking parts.
