Description

technical field

[0001] The present invention relates to a sealing structure of a gear box housing a gear set for outputting an electric motor as a drive source, for example, in a table cutter or a portable cutter with a circular rotary cutter. The rotational drive force is decelerated and output. Background technique

[0002] For example, a desktop cutting machine has: a workbench for placing pieces to be cut; a cutting machine body supported by the workbench and capable of moving up and down relative to the workbench. As far as the desktop cutting machine is concerned, the cutting process is carried out by making the cutting machine body swing down and allowing the rotary knife to cut into the piece to be cut.

[0003] The portable cutting machine has a structure that has a base that is placed on the upper surface of a piece to be cut, a cutter body that is supported by the upper surface of the base, and a lower portion of the rotary cutter protruding toward the lower surf...

Embodiment Construction

[0025] Below, refer to Figure 1 to Figure 5 Specific embodiments of the present invention will be described. figure 1 The whole desktop cutting machine 1 which has the sealing structure of this embodiment is shown. In the present embodiment, a so-called sliding table cutter is exemplified as the table cutter 1 . figure 1 In , the user operates the desktop cutting machine 1 on the right side of the figure. In the following description, the side closer to the user ( figure 1 the middle right side) as the front side, and the side away from the user ( figure 1 middle left) as the rear side. In addition, if figure 2 As shown, left and right are based on the user, when the user stands in front of the desktop cutting machine 1 .

[0026] The desktop cutting machine 1 has: a workbench 2 for supporting the pieces W1 and W2 to be cut; a base 3 supporting the workbench 2 in a horizontally rotatable state; Fuselage supporting part 5 on platform 2. The table 2 is supported on the...
