とを特徴としたギヤ変速切換機構。 A pair of high-speed and low-speed gears are arranged to be slidable in the axial direction on the output shaft of the power tool, a gear cover that holds the output shaft and the gear pair, and a gear cover that rotates orthogonally to the output shaft on the side surface of the gear cover. A movable lever is arranged, and a pin is fixed to the rotary lever eccentrically to the center of rotation,
In the gear transmission mechanism in which the gear pair is moved by rotation of the rotary lever that is locked to the gear pair, and the gear pair is changed to select high speed or low speed of the output shaft by changing engagement with the intermediate gear pair, the rotary lever A claw part that protrudes from the outer periphery of the rotation shaft and has elasticity, and a protrusion that protrudes from the outer periphery of the rotation shaft is provided at the tip of a similarly elastic rib, and the claw part is locked to the inner wall of the gear cover. The gear shift is characterized in that the rotary lever is held by the gear cover, and the protrusion is engaged with a recess provided on the inner circumference of the gear cover into which the rotary shaft fits, thereby setting the rotation angle and positioning. Switching mechanism.
