Zusammenfassung:	A power tool (11) includes a transmission mechanism (17) capable of selecting one of a plurality of transmission gear ratios by changing a combination of gears of a gear train (30) to be meshed with each other, a transmission ratio switching operation unit (25; 26) capable of turning around the thrust shaft and operating to change the combination of the gears, a gear operation mechanism (63, 29a, 42c, 46b) to move a transmission gear (42; 46) of the gear train in a thrust shaft direction in accordance with turning motion of the transmission ratio switching operation unit, and a biasing mechanism (32, 65) to bias the gear operation mechanism in accordance with the turning motion of the transmission ratio switching operation unit such that the transmission gear moves in the thrust shaft direction and meshes with a meshed gear corresponding to the selected transmission gear ratio.
