Abstract: 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.

Abstract: A cutting device may include a cutting unit having a cutter for trimming an edge portion of a workpiece or forming a groove in a workpiece. The cutting device may further include a base assembly configured to support the cutting unit with respect to the workpiece, and a grip device capable of being mounted to and removed from the cutting unit independently of the base assembly and configured to be capable of being grasped by a user during a cutting operation.

Abstract: 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.

Abstract: A power tool that includes a reservoir that holds oil and a cap attached to the reservoir. The cap may include a cap body having a communicating path and a valve member covering the communicating path. The valve member may include an elastic part that has a projecting part, which projects from the elastic part and includes a slit. The elastic part and the projecting part being configured to deform to the inner surface side such that the slit of the projecting part opens if the pressure outside the reservoir becomes higher than the pressure inside the reservoir and a difference between the pressure inside the reservoir and the pressure outside the reservoir exceeds a predetermined value. The elastic part and the projecting part also being configured to deform to the outer side surface such that the slit of the projecting part opens if the pressure inside the reservoir becomes higher than the pressure outside the reservoir.

Abstract: 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.

Abstract: A coupling member can releasably couple a blade protector to a tool body of a gardening tool. The coupling member is movably and non-removably coupled to one of the tool body and the protector.

Abstract: A linear motion mechanism comprises a second rotating shaft having an external thread portion 48a at least at a part of an area in a length direction and an adjusting pin 40 having an opening 60 through which the external thread portion 48a passes. The opening 60 of the adjusting pin 40 has a cross-sectional shape that enables the adjusting pin 40 to move in a radial direction of the second rotating shaft. An inner thread part 62 that engages with and disengages from the external thread portion 48a of the second rotating shaft depending on a position of the adjusting pin 40 is formed on an inner surface of the opening 60. A spring 56 capable of retaining a state in which the external thread portion 48a and the inner thread part 62 engage with each other is arranged on the adjusting pin 40.

Abstract: 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. The valve member may comprise a bulging part and a projecting part. The bulging part may be curved in a dome shape. The projecting part may project from the bulging part and comprises a slit at its top portion.

Abstract: A handheld electric power tool comprises a main body supporting a tool, a motor housed in the main body and configured to drive the tool, a battery interface disposed in a back portion of the main body and configured to detachably receive a battery pack, and a top grip disposed on a top portion of the main body. In a planar view of the main body, a center axis of the top grip extends in front and back direction and a center of gravity of the battery pack attached to the battery interface is located at one side of a straight line passing through the center axis of the top grip.

Abstract: A cutting tool includes a saw blade and a blade case adapted to cover the saw blade. A light may have a light for illuminating a portion of a workpiece that will be cut by the saw blade during a cutting operation. The light may be mounted within the blade case, so that the light is laterally displaced from the saw blade. A mounting device may be utilized to receive the light and the mounting device may be disposed within the blade case.

Abstract: Portable circular saws are taught that may include a base and a saw unit pivotally coupled to the base. The saw unit may have a circular saw blade that is adapted to laterally pivot relative to the base. A stopper may be provided to allow an operator to selectively stop the saw unit at a second pivot angle that is between a first pivot angle and a third pivot angle. Preferably, the stopper may have an operative position and a non-operative position. In the operative position, the saw unit can pivot from the first pivot angle to the third pivot angle without stopping at the second pivot angle. In the non-operative position, the saw unit can pivot between the first pivot angle and the second pivot angle. A first stopper may be provided to permit the saw to be selectively stopped at a small angle pivot position (e.g. 0°) before a minimum pivot angle (e.g. −5°). A second stopper may be provided to permit the saw to be selectively stopped at a large angle pivot position (e.g.
