摘要： A changeover operation device, for changing over the positions of at least two components to establish three or more speed modes in a speed changer mechanism accommodated within a housing having an opening, includes operation handles arranged in a corresponding relationship with the components. Each of the operation handles is movable between two specified positions along a specified operation direction to change over the positions of the components. The operation handles are continuously arranged within the opening of the housing, one of the operation handles being partially overlapped with the other.

摘要： An impact tool for simultaneously providing a rotational force and an impact force to an object has an output shaft rotated by a motor, hammer for intermittently providing an impact force to the output shaft, hammer holder for movably holding the hammer, and an impact force generator for generating the impact force from an output of the motor. An air chamber is formed between the hammer and the hammer holder such that a volume of the air chamber is variable in response to a position of the hammer relative to the hammer holder. In addition, the hammer receives a bias force generated in a direction toward the output shaft by a biasing device. This bias force effectively increases the impact force in cooperation with an air pressure caused by a volume change of the air chamber.
