摘要： A valve actuating mechanism includes a first rocker arm moving mechanism including a first spring for urging left and right rocker arms from a first operation position side towards a second operation position side. The valve actuating mechanism also includes a second rocker arm moving mechanism including a second spring for urging the left and right rocker arms from the second operation position side towards the first operation position side. When a predetermined force is applied to the left and right rocker arms by one of the respective springs, the rocker arms are configured to be moved to operation positions corresponding to the applied force.

摘要： A commutator main body has a cylindrical insulating body, and a plurality of segments arranged in an outer circumference of the insulating body. A short-circuit member is arranged in an end in an axial direction of the insulating body. The short-circuit member has a plurality of first short-circuit pieces and a plurality of second short-circuit pieces. A tabular insulating portion covers first coupling portions of the first short-circuit pieces, and second coupling portions of the second short-circuit pieces. The insulating portion has a restriction recess, and the end in the axial direction has a restriction projection. The restriction projection is engaged with the restriction recess, whereby the movement of the short-circuit member in the circumferential direction with respect to the commutator main body is restricted. Accordingly, the assembly of the short-circuit member in the commutator main body is facilitated.

摘要： A stator of a direct current motor includes six magnetic poles. An armature of the direct current motor includes an armature core having eight slots, a plurality of windings wound around the armature core as concentrated windings, and a commutator having twenty-four segments connected to the windings. The plurality of windings are connected to one another to form a single closed loop. The direct current motor further includes an anode power supply brush and a cathode power supply brush that slidably contact the segments. The aspect ratio, which is the ratio of the diameter of the armature core with respect to the length in the axial direction of the armature core is set to a range of 3.2 through 5.6. This increases the constraint torque/mass ratio of the direct current motor.
