Driver drill and hammer driver drill
A driver drill may include: a motor; an output part provided forward of the motor and driven by the motor; a speed reduction mechanism disposed between the motor and the output part; a motor bracket disposed between the motor and the speed reduction mechanism; a housing that houses the motor and the motor bracket; an element provided above the motor or the speed reduction mechanism; and a lead wire connected to the element and extending more downward than the motor or the speed reduction mechanism. The lead wire may be sandwiched between the housing and the motor bracket.
1 . A driver drill comprising:
a motor;
an output part provided forward of the motor and driven by the motor;
a speed reduction mechanism disposed between the motor and the output part;
a motor bracket disposed between the motor and the speed reduction mechanism;
a housing that houses the motor and the motor bracket;
an element provided above the motor or the speed reduction mechanism; and
a lead wire connected to the element and extending more downward than the motor or the speed reduction mechanism, wherein
the lead wire is sandwiched between the housing surrounding an outer circumference of the motor bracket and the motor bracket.
2 . The driver drill according to claim 1 , further comprising
a hammer mechanism that hammers the output part.
3 . The driver drill according to claim 1 , wherein
the speed reduction mechanism is a multi-stage speed changer,
the driver drill further comprises a speed switching lever that is disposed in an upper portion of the housing and that is operable by a user to switch a speed reduction ratio of the speed reduction mechanism, and
the element includes a sensor that detects the switching of the speed reduction ratio in response to the speed switching lever being operated.
4 . The driver drill according to claim 1 , wherein
the element includes a notification lamp that notifies a driving state of the motor.
5 . The driver drill according to claim 1 , wherein
the element includes an operation switch that receives an operation input.
6 . A driver drill comprising:
a motor;
an output part provided forward of the motor and driven by the motor;
a speed reduction mechanism disposed between the motor and the output part;
a motor bracket disposed between the motor and the speed reduction mechanism;
a housing that houses the motor and the motor bracket;
an element provided above the motor or the speed reduction mechanism; and
a lead wire connected to the element and extending more downward than the motor or the speed reduction mechanism, wherein
the lead wire is sandwiched between the housing and the motor bracket,
the housing has, on an inner surface of the housing, a recess in which the lead wire is disposed, and
the motor bracket has, on an outer circumference of the motor bracket, a protrusion protruding toward the recess.
7 . The driver drill according to claim 6 , wherein
the protrusion includes a first protrusion and a second protrusion arranged in a circumferential direction of the motor bracket, and
in a radial direction of a rotation axis of the motor, a distance from the rotation axis to a leading end of the first protrusion is shorter than a distance from the rotation axis to a leading end of the second protrusion.
8 . The driver drill according to claim 7 , wherein
the first protrusion is disposed on a side surface of the motor bracket, and
the second protrusion is disposed, on the motor bracket, more upward or downward than the first protrusion.
9 . A hammer driver drill comprising:
a motor;
an output part provided forward of the motor and driven by the motor;
a speed reduction mechanism disposed between the motor and the output part;
a hammer mechanism disposed between the output part and the speed reduction mechanism;
a motor bracket disposed between the motor and the speed reduction mechanism so as to position the motor and the speed reduction mechanism;
a housing that houses the motor and the speed reduction mechanism;
an element provided above the motor and the speed reduction mechanism; and
a controller provided downward of the motor and connected to the element via a lead wire, wherein
a passage through which the lead wire passes is provided between the motor and the speed reduction mechanism in a front-rear direction, and
the passage is provided between the motor bracket and the housing surrounding an outer circumference of the motor bracket.
10 . The hammer driver drill according to claim 9 ,
the speed reduction mechanism is a multi-stage speed changer,
the driver drill further comprises a speed switching lever that is disposed in an upper portion of the housing and that is operable by a user to switch a speed reduction ratio of the speed reduction mechanism, and
the element includes a sensor that detects the switching of the speed reduction ratio in response to the speed switching lever being operated.
11 . The hammer driver drill according to claim 9 , wherein
the element includes a notification lamp that notifies a driving state of the motor.
12 . The hammer driver drill according to claim 9 , wherein
the element includes an operation switch that receives an operation input.
