Band length extension mechanism, band, and timepiece

Abstract

There is provided a band length extension mechanism that allows switching between a folded state and a deployed state, the band length extension mechanism including: an adjustment link; a link piece; an extension piece that couples the adjustment link and the link piece to each other; and a locking member, in which the extension piece is rotatably coupled to the adjustment link at a first shaft and is rotatably coupled to the link piece at a second shaft, in the folded state, the extension piece is stored in an overlapping manner with the adjustment link and the link piece, in the deployed state, the adjustment link, the extension piece, and the link piece are deployed and extended, the locking member is slidably provided on one surface of the adjustment link, and in the folded state, the locking member is engaged with the extension piece to achieve locking.
