Abstract:
A recoil starter, comprising:a driving member having a rope reel, recoiling urging means for reversibly rotating the rope reel, and an interlocking rotor to which the rotation of the rope reel is enabled to be transmitted; and a driven member operationally coupled to said driving member, to which the rotation of said driving member is transmitted; said driving member further comprising recoiling unidirectional rotating means operationally coupled to said interlocking rotor, said recoiling unidirectional rotating means including a movable locking claw member supported by one of said rope reel and said interlocking rotor in such a manner that it is rotatable integrally therewith and movable in a direction along the rotational axis thereof; an urging member for urging said movable locking claw member toward the other of said rope reel and said interlocking rotor; and an engaging member mounted on the other of said rope reel and said interlocking rotor; said unidirectional rotating means being constructed in such a manner that when said rope reel is rotated in the driving direction, said movable locking claw member is caused to contact and engage with said engaging member to thereby enable said rotation of the rope reel to be transmitted to said interlocking rotor, and when said rope reel is rotated reversibly to said driving direction relative to said interlocking rotor, the engagement between said movable locking claw member and said engaging member is released; a buffering/power-accumulating means disposed between said driving member and said driven member, said buffering/power-accumulating means being a spiral spring mechanism that is thereby enabled, during the driving process by the driving member, to accumulate the power supplied by the driving process while alleviating any impact to be imposed by the driving member, the accumulated power being subsequently employed for driving the driven member.
