A recoil starter featuring a capability of efficiently cooling an engine, easy fabrication and handlings of a power storage spiral spring and an enhanced assemblability is provided. The recoil starter comprises: a starter case unitary with a starter shaft; a one way clutch mechanism comprising a cylinder cam mounted to the starter shaft, a cup-shaped pulley mounted on an engine side, and a ratchet mechanism mounted to the pulley or the cylinder cam and brought into or out of engagement with the cylinder cam or the cup-shaped pulley; a reel pivotally mounted to the starter shafts; a recoil spiral spring anchored to the starter case and the reel at both ends thereof and biased in a direction to wind up the rope; and a power storage spiral spring accommodated in a cassette type spring case and operative to resiliently transmit a reel torque to the cylinder cam when the rope is pulled out, wherein air inlet ports for introducing a cooling air for engine are disposed at an outside surface and outer periphery of the starter case, a side surface of the reel and a side surface of the spring case for the power storage spiral spring.
