20120061115 | POWER TOOL - A fixed operating knob is rotatably arranged on a chain saw body. The fixed operating knob comprises a knob body, a tab, a torsion spring, and a lock member. The knob body is rotatably attached to the chain saw body. The tab is attached to the knob body. The tab is attached so as to be capable of swinging between an operating position projecting from the knob body and a storing position stored in the knob body. The torsion spring biases the tab toward the operating position. When the tab moves to the storing position, the lock member retains the tab at the storing position against a biasing force of the torsion spring. | 03-15-2012 |
20120061393 | POWER TOOL - A chain saw comprises an oil tank and an oil cap. The oil cap comprises a cap body and a valve member. The cap body may comprise a communicating path communicating an inside of the oil tank to an outside of the oil tank. The valve member may be attached to the cap body and covers the communicating path. The valve member may be a sheet-shaped portion made from elastomer.

20140048301 | ELECTRIC TOOLS - An electric tool may include a tubular housing, a motor disposed within the housing, and a tool holder rotatably driven by the motor and capable of holding an end tool. A shoe may be supported by the housing and may determine a protruding length of the end tool from one end of the housing. A battery mount portion may be disposed at the other end of the housing. The battery may be mounted to the battery mount portion as the battery is slid relative to the battery mount portion along a direction intersecting the extending direction of the housing. | 02-20-2014 |
20140116738 | ELECTRIC POWER TOOL - A shoe attached to a shoe attachment portion includes a spanner portion. As the shoe can be separated from a tool main body of the cutout tool, the shoe can be used as a spanner. The shoe can function as the spanner for replacing a bit in a bit attachment mechanism. In addition, the shoe has its original function of the shoe by which a protrusion amount of the bit can be adjusted. Since the shoe is attached to the shoe attachment portion and held by the tool main body, it turns out that the spanner can be prepared for use with the cutout tool. | 05-01-2014 |
