LAWN MOWER

PROBLEM TO BE SOLVED: To provide a miniaturized lawn mower having an electric motor of a small rotational frequency, and with a high efficiency in collecting grass and excellent operability.SOLUTION: The motor 50 as a power supply for the lawn mower includes: a rotator 53 which integrally rotates with an output shaft 52; and a stator 54 fixed to a housing 30; wherein the arrangement is made in a manner that the output shaft 52 is disposed about vertically. The rotator 53 has a disk-shaped coil disk on which a plurality of annular coils are disposed in the circumferential direction around the output shaft 52 as seen in the axial direction of the output shaft 52. The stator 54 has a magnet 71 which generates a magnetic flux passing through the coil disk in the axial direction of the output shaft 52, an upper yoke 72, and a lower yoke 73. A rotary blade 33 for mowing grass is attached to the output shaft 52 of the motor 50. A power transmission mechanism 46 is attached to the motor 50 and a fan 37 for feeding the mown grass, so that the speed of the power from the motor 50 is increased and the power is transmitted to the fan 37.
