な構成をした工具保持部7が設けられている。[0003] A conventional power tool incorporates a motor and a deceleration mechanism (not shown), is connected to the motor via the deceleration mechanism, and rotatably holds a spindle 3 rotatable by receiving the power of the motor; It has a switch 10 for controlling the driving of the electric motor, and a handle portion 2 provided to be connected to the rear end (left side in FIG. 13) of the main body 1 so as to be substantially orthogonal to the axial direction of the spindle 3. It has a configuration with. At the tip of the spindle 3, there is provided a tool holding portion 7 having a structure in which a tip tool can be attached and detached.

6, the power tool main body is held by gripping the handle portion 2 and the work is performed. The power point 8 when applying the thrust F to the power tool main body during the work is far away from the axis 4 of the spindle 3. Since the vertical distance X between the axis 4 and the power point 8 is large, when a thrust F is applied to the power tool main body at the time of work, a moment M applied in a direction of rotating the power tool main body with the tip tool as a fulcrum is obtained. There was a disadvantage that it became relatively large.

とにも関連する。As a method for reducing the moment M, as shown in FIGS. 17 and 18, a thrust F is applied to the power tool main body near the axis 4 of the spindle 3 so as to apply a thrust F to the power tool main body. There is a method of holding the power tool main body by gripping the end and the side surface of the main body 1. In this case, as shown in FIG. 18, the vertical distance X between the axis 4 and the force point 8 is reduced and the moment M is reduced, so that a drilling tool can easily perform drilling perpendicular to the machined surface. Has advantages. In this type of power tool, the center of gravity is located at the spindle 3 in the main body 1.
In the method of holding the power tool main body shown in FIGS. 15 and 16, the power point 8 for applying thrust to the power tool main body is away from the center of gravity in the vertical direction. Also, the holding method shown in FIG. 18 relates to the fact that the force point 8 for applying the thrust is close to the position of the center of gravity in the vertical direction.

のであった。As described above, when the power tool main body is held as shown in FIGS. 17 and 18, the moment M applied to the power tool main body when the thrust F is applied to the power tool main body can be reduced. However, in terms of holding the power tool main body, in order to position the first finger and the second finger on the side of the main body 1 as compared with the holding method of holding the handle 2 as shown in FIGS. It was difficult to hold.

However, since the surface of the depression 9 is often hard and has a relatively small friction coefficient, the first finger and the second finger are easily slipped, and the side surface of the main body 1 is held between the first finger and the second finger. When the power tool main body is held, the force applied to the first finger and the second finger must be increased.

であった。In recent years, a cover 5 whose surface is larger than the friction coefficient of the main body 1 and the handle 2 has been proposed in order to prevent slippage when holding the power tool main body.
As shown in FIGS. 9, 20, 21, and 22, there is a configuration provided so as to cover a part of the side surface of the handle portion 2 opposite the spindle and the vicinity of the end surface of the body portion 1 opposite the spindle side.
As shown in FIGS. 16 and 17, when the power tool main body is held, the cover 5 is not provided at the side of the main body 1 where the first finger and the second finger are located. As shown in FIGS. 16 and 17, when the power tool main body is held, the first finger and the second finger are slippery, and the force applied to the first finger and the second finger must be increased. .

As shown in FIGS. 11 and 12, the handle 2 and the end of the main body 1 on the opposite side of the spindle and the side of the main body 1 are gripped, and the axis 4
When the power tool main body is held so that a thrust can be applied to the power tool main body at the opposite end of the main body portion 2 on the side opposite to the spindle, the first finger is placed on the cover 5 located on both side surfaces of the main body portion 1. And the second finger are located, and the first finger and the second finger are less likely to slip. Thereby, when holding the power tool main body by holding the side surface of the main body 1 between the first finger and the second finger, the force applied to the first finger and the second finger can be suppressed, and the workability can be improved. You can plan. In particular, since the length L of the cover 3 in the longitudinal direction of the spindle 3 is larger than at least the length of the second finger, the cover 5 is located at the fingertips of the first finger and the second finger. It becomes easy to hold the side of the main body 1.

According to page 192 of "Human Body Dimension Data Collection for Design" (published by Nippon Shuppan Service Co., Ltd.), the length of the second finger in young boys occupies 97.5% or less of 78 mm or less. With
In this embodiment, the dimension L of the cover 5 in the longitudinal direction of the spindle 3 is set to about 110 mm which satisfies 78 mm or more. Further, it is desirable that the width dimension W of the cover 5 be equal to or larger than the width of the second finger. The average value of the maximum width is 16.4 mm, and in the present embodiment, the width dimension W is set to about 25 mm, which is larger than the average value. Note that the width W of the cover 5 does not necessarily need to be equal to or greater than the width of the second finger, and may be equal to or less than the width of the second finger as long as the sliding of the first finger and the second finger can be suppressed. .
