Claim 7:
8. A grinder, comprising:
a motor including an output shaft having a longitudinal rotation axis in a front-rear direction;
a housing accommodating the motor and extending in the front-rear direction;
a switch in the housing and configured to drive the motor;
a brake member in the housing and movable between a rear braking position to apply a brake on the output shaft and a front brake release position to release the brake on the output shaft;
a switch lever (i) movable between an initial position to protrude from the housing and a depressed position to be depressed into the housing and (ii) having a through-hole;
a sliding member (i) in the housing and (ii) slidable between a first position to move the brake member to the front brake release position and a second position to move the brake member to the rear braking position; and
a link member (i) in the housing, (ii) rotatable between a first rotational position to move the sliding member to the first position at the depressed position of the switch lever and a second rotational position to move the sliding member to the second position at the initial position of the switch lever, (iii) being configured to turn on the switch at the first rotational position and turn off the switch at the second rotational position, (iv) between the switch and the brake member, and (v) including:
a front arm (a) extending radially and in contact with the switch lever and (b) being configured to rotate the link member to the first rotational position and the second rotational position in accordance with movement of the switch lever,
a rear arm (a) extending radially and engaged with the sliding member through the through-hole and (b) being configured to move the sliding member to the first position and the second position in accordance with rotation of the link member to the first rotational position and the second rotational position.
