Abstract: An electric work machine includes: a motor; a first planetary gear mechanism; a second planetary gear mechanism; a spindle; a first speed switch mechanism including a first internal gear of a first stage unit and a second internal gear of a second stage unit; and a second speed switch mechanism. The first speed switch mechanism performs switching between a first speed reducing mode in which rotation of the second internal gear is prevented and rotation of the first internal gear is allowed and a second speed reducing mode in which rotation of the first internal gear is prevented and rotation of the second internal gear is allowed. The second speed switch mechanism performs switching between an enabled mode in which rotation of an internal gear of the second planetary gear mechanism is prevented and a disabled mode in which the rotation of the internal gear is allowed.

Abstract: An electric work machine reduces damage to its components under a greater load on a spindle. An electric work machine includes a motor, a planetary gear assembly rotatable with a rotational force from the motor and including a carrier having a hole having an inner surface including two carrier flat surfaces, a spindle including a rear portion received in the hole and having an outer surface including two spindle flat surfaces, and a spindle locking assembly that transmits a rotational force in one direction from the carrier to the spindle and including a lock cam surrounding the spindle frontward from a front surface of the carrier and rotatable together with the spindle, a lock ring surrounding the lock cam, and a plurality of cylindrical members between the lock cam and the lock ring.

Abstract: A connection structure and terminal fitting are provided for suppressing the height of a deformed front end portion of a conductor. The connection structure and terminal fitting include a wire barrel (25), in which a pair of crimping pieces (27) stand up from a bottom wall (26), and a wire (10), including a conductor (11) formed by twisting a plurality of metal thin wires. The crimping pieces (27) in the wire barrel (25) compress the conductor (11) while surrounding it to electrically connect the conductor (11). The front end of the conductor projects forward from the front end of the wire barrel. Pressing portions (29) closer to the bottom wall (26) than rear end areas of the crimping pieces (27) are formed in the front ends of the upper walls (28) of the crimping pieces (27) at a side of the conductor (11) opposite to the bottom wall (26).
