A recoil starter is provided with a circular cross section ratchet member rotatably mounted on a shaft hole. The ratchet member is configured by: a rotary shaft portion inserted into the shaft hole; an arm portion bent at a substantially right angle and extending from the rotary shaft portion; and a distal end portion bent parallel to the rotary shaft portion and extending from the arm portion. The ratchet member rotates upon rotation of a rope reel in an engine start direction, engages with a drive pulley by the rotation, and transmits torque of the rope reel to the drive pulley.

摘要： An engine starting device includes a self-starting motor drivable to rotate the crankshaft of an engines, and a one-way clutch operable to permit transmission of rotary motion of the self-starting motor in one direction only to the crankshaft. The one-way clutch includes an inner race operatively connected to an output shaft of the self-starting motor, an outer race operatively connected to the crankshaft, a plurality of ratchet pawls pivotally connected to the inner race and urged by springs against the inner race. The one-way clutch is designed such that, when the speed of rotation of the inner race while being rotated by the self-starting motor goes up to a predetermined value, the ratchet pawls are caused to swing in a radial outward direction under the action of centrifugal force against the bias of the springs and become engaged by the outer race to thereby engage the one-way clutch.

摘要： A recoil starter is disclosed which enables a rotational force to be accumulated in accumulating means with a light pulling force and the accumulated rotational force to start an engine through simple operations. A cam wheel is rotated using a rotational force which has been accumulated in the accumulating means by pulling a recoil rope. Retention means is operable to restrain or permit the rotation of the cam wheel. Release means operates the retention means to restrain the rotation of the cam wheel by pulling a handle attached to the recoil rope, and operates the retention means to permit the rotation of the cam wheel by fixing the handle in a main casing.
