Abstract

In a magneto generator, second phase lead wires (10a, 10b) and third phase lead wires (11a, 11b) among individual one pair of first, second and third lead wires (9a, 9b; 10a, 10b; 11a, 11b) are covered with first protective tubes (12a, 12b), respectively. The second phase lead wires (10a, 10b) and the third phase lead wires (11a, 11b) covered with the first protective tubes (12a, 12b) are bent toward the first phase lead wires (9a, 9b) in a circumferential direction and bundled together with the first phase lead wires (9a, 9b). The first phase lead wires (9a, 9b), the second phase lead wires (10a, 10b) and the third phase lead wires (11a, 11b) thus bundled are bent in a direction opposite to the circumferential direction and covered with second protective tubes (22a, 22b, 22c), respectively.

Claims

1. A magneto generator comprising:

a flywheel that rotates about an axis of rotation;

a plurality of permanent magnets that are arranged on an inner peripheral wall surface of said flywheel in a circumferential direction thereof and fixedly secured thereto;

a stator core that is arranged at a diametrally inner side of said flywheel with its outer peripheral surface being in opposition to said permanent magnets; and

a magneto coil that has an conductor wound around each of teeth that are formed on an outer peripheral portion of said stator core so as to radially protrude in diametrally outer directions at equal intervals, said magneto coil also having a lead wire that is led outwardly from said stator core;

a lead that has one end portion thereof electrically connected to said lead wire and the other end thereof electrically connected to electrical equipment; and

a lead clamp that has a basal end fixedly attached to said stator core by a tightening element, and an opening portion that opens to said magneto coil;

wherein said lead clamp covers said lead and at the same time presses said lead toward said magneto coil through said opening portion, and

wherein said lead clamp has a bent portion whose diametral outermost portion is bent toward said magneto coil, such that a pressing direction of said lead clamp is the same as a direction in which said opening portion opens to said magneto coil.

2. The magneto generator as set forth in claim 1, wherein said lead clamp is arranged between adjoining ones of said teeth when viewed along the direction of said axis of rotation.

3. The magneto generator as set forth in claim 1, wherein said lead clamp is formed with a plurality of protrusions protruding to said magneto coil.

4. A magneto generator comprising:

a flywheel that rotates about an axis of rotation;

a plurality of permanent magnets that are arranged on an inner peripheral wall surface of said flywheel in a circumferential direction thereof and fixedly secured thereto;

a stator core that is arranged at a diametrally inner side of said flywheel with its outer peripheral surface being in opposition to said permanent magnets; and

a magneto coil that has an conductor wound around each of teeth that are formed on an outer peripheral portion of said stator core so as to radially protrude in diametrally outer directions at equal intervals, said magneto coil also having a lead wire that is led outwardly from said stator core;

a lead that has one end portion thereof electrically connected to said lead wire and the other end thereof electrically connected to electrical equipment; and

a lead clamp that has a basal end fixedly attached to said stator core by a tightening element, and an opening portion that opens to said magneto coil;

wherein said lead clamp covers said lead and at the same time presses said lead toward said magneto coil through said opening portion, and

wherein an elastic member is arranged between said lead clamp and said lead.
