Abstract: A rope reel includes first circumferential wall portion that is erectly provided so as to surround outer circumference of recoil spring. A starter case includes second circumferential wall portion that is erectly provided so as to adjoin inner circumferential face or outer circumferential face of first circumferential wall portion. The first circumferential wall portion and the second circumferential wall portion are disposed so that end edges of the first circumferential wall portion and the second circumferential wall portion overlap each other when viewed in radial direction. A plate is disposed between starter case and recoil spring inside first circumferential wall portion. Thus, it is possible to provide structure which is realized in space-saving manner to make foreign substances difficult to intrude into starting device in order to prevent deformation or damage of recoil spring, and from which the foreign substances are easily discharged even if foreign substances have intruded.

Abstract: A recoil starter exemplified in the embodiment includes: a starter case; a rope reel; a recoil rope; a ratchet; and a drive pulley. When the rope reel is rotated by pulling the recoil rope, the ratchet pivots to engage an engaged unit of the drive pulley to thereby transmit a torque of the rope reel to an engine. The rope reel has: a ratchet receiving unit; and a reinforcing unit. The ratchet receiving unit is arranged to receive a front end portion of the ratchet when it is engaged with the engaged unit of the drive pulley. And, the reinforcing unit extends in a circumferential direction of the rope reel with respect to the ratchet receiving unit as its leg portion.
