PROBLEM TO BE SOLVED: To provide a bay window capable of controlling the occurrence of deviation between a jamb and a side head or a side sill and increasing air-tightness and cut-off efficiency. SOLUTION: In the bay window 1 having a side frame 6 formed by clamping the side head 4 and the side sill 5 put across between the jamb 2 and a mullion 3 with a through-bolt 18, a hole section 19 passing through a stem section 18a of the through-bolt 18 is formed in the jamb 2, a guide hole 20 passing through the stem section 18a of the through-bolt 18 is formed in the side head 3 and the side sill 5, and an enlarged stem section 18d thicker than the shaft section 18a is formed in part across the hole section 19 and the guide hole 20 in the stem section 18a of the through-bolt 18.
