A scroll saw includes a work platform, a C-shaped frame, a blade unit, a blade holder unit, a motor unit, a transmission unit, a pivot unit, and a locking unit. The C-shaped frame has upper and lower frame portions disposed above and below a top side of the work platform. The blade unit has blade ends retained on the blade holder unit. The motor unit drives the blade holder unit via the transmission unit for moving the blade unit to reciprocate relative to the work platform. The pivot unit mounts pivotally the C-shaped frame on the work platform about a pivot axis in the longitudinal direction, thereby permitting sawing angle adjustment. The locking unit locks releasable the C-shaped frame to the work platform so as to arrest pivoting movement of the C-shaped frame relative to the work platform.
