## 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.

## Claims

### Claim 1

A recoil starter including:
a starter case (11);
a rope reel (12) attached rotatable to the starter case (11);
a recoil rope (13) wound around the rope reel (12);
a ratchet (14) pivotably attached to the rope reel (12); and
a drive pulley (15) connected to an engine, the drive pulley (15) having an engaged unit (15a) engageable with the ratchet (14),
wherein, when the rope reel is rotated by pulling the recoil rope (13), the ratchet (14) pivots to engage the engaged unit (15a) of the drive pulley (15) to thereby transmit a torque of the rope reel (12) to an engine, and
wherein the rope reel (12) has:
a ratchet receiving unit (12c) arranged to receive a front end portion (14b) of the ratchet (14) when it is engaged with the engaged unit (15a) of the drive pulley (15); and
a reinforcing unit (12d) that extends in a circumferential direction of the rope reel (12) with respect to the ratchet receiving unit as its leg portion.

### Claim 2 (depends on 1)

The recoil starter of claim 1,
wherein the reinforcing unit (12d) is formed to cover the front end portion (14b) of the ratchet (14) when it contacts the ratchet receiving unit (12c) and to thereby suppress floating of the front end portion (14b) of the ratchet (14).

### Claim 3 (depends on 1)

The recoil starter of claim 1,
wherein two ratchet receiving units (12c, 12c) are provided as the ratchet receiving unit (12c) in a line symmetry manner with respect to the reinforcing unit (12d).

### Claim 4 (depends on 3)

The recoil starter of claim 3, further including:
a control member (18) attached to the starter case (11) concentrically with the rope reel (12),
wherein the ratchet (14) has a projection (14c), and the control member (18) has an engaging groove (18a) which receives the projection (14c) and which extends to guide a pivoting movement of the ratchet (14) to project radial outward, and
wherein two engaging grooves (18a) are provided as the engaging groove (18a) in a line symmetry manner.
