Abstract:
It is an object of the invention to increase the degree of freedom in designing a power tool. A representative power tool has a spindle that transmits a driving force of a motor to a tool accessory, a tool accessory holding member that is configured to be movable in a direction of a spindle rotation axis direction between a holding position for holding the tool accessory and a releasing position for releasing the tool accessory, a lock mechanism that locks the tool accessory holding member in the holding position, and a body housing. The lock mechanism is disposed between a second end of the spindle and a wall of the body housing in the spindle rotation axis direction.

Claim (Index 1):
A power tool configured to perform an operation on a workpiece by driving a tool accessory, the power tool comprising:\n a motor; a spindle configured to transmit a driving force of the motor to the tool accessary; a tool accessory holding member configured to move in an axial direction of the spindle between a holding position for holding the tool accessory and a releasing position for releasing the tool accessory; and a lock mechanism configured to engage with the tool accessory holding member in the holding position and lock the tool accessory holding member, wherein: the lock mechanism includes: a collar member; and a clamp member held by the collar member to be movable between an engaging position and a disengaging positon, the clamp member being engageable with the tool accessory holding member in the engaging position and being disengageable with the tool accessory holding member in the disengaging position, and the collar member includes a first inclined part and a second inclined part spaced apart from each other in the axial direction of the spindle and each being inclined relative to an axis of the spindle, and the clamp member includes a third inclined part and a fourth inclined part spaced apart from each other in the axial direction of the spindle, the third inclined part and the fourth inclined part being configured to slide in contact with the first inclined part and the second inclined part, respectively.
