Tool

A grinder comprising:

• an electric motor;
• a tool accessory configured to be rotated by the electric motor;
• a side grip;
• at least two first attachment portions for detachably and selectively attaching the side grip;
• a single first intermediate member provided in common for the at least two first attachment portions, the first intermediate member including a first intermediate member main body having an annular shape or a partially annular shape and at least two pressed portions disposed at at least two positions respectively corresponding to positions of the at least two first attachment portions, the at least two pressed portions being configured to, when the side grip is attached to one first attachment portion arbitrarily selected from the at least two first attachment portions, be directly or indirectly pressed by the side grip, the first intermediate member being configured to be rotated in a circumferential direction of the annular shape or the partially annular shape when any of the at least two pressed portions is pressed;
• a biasing member configured to bias the first intermediate member toward a position at which the first intermediate member is located when being not pressed directly or indirectly by the side grip;
• and
• a single first sensor configured to detect that the first intermediate member is rotated,
• wherein the at least two first attachment portions are disposed at the positions spaced apart from each other in the circumferential direction, respectively, and
• each of the at least two pressed portions includes a pressed surface angled with respect to a pressing direction in such a manner that the first intermediate member is rotated in a direction different from the pressing direction, and wherein each of the at least two pressed portions protrudes radially outward from the first intermediate member main body, the pressing direction being a direction in which the side grip directly or indirectly presses any of the at least two pressed portions.

A tool comprising:

• a first accessory;
• at least two first attachment portions for detachably and selectively attaching the first accessory;
• a single first intermediate member provided in common for the at least two first attachment portions, the first intermediate member including at least one pressed portion configured to, when the first accessory is attached to one first attachment portion arbitrarily selected from the at least two first attachment portions, be directly or indirectly pressed by the first accessory, the first intermediate member being configured to be displaced when the at least one pressed portion is pressed;
• and
• a single first sensor configured to detect that the first intermediate member is displaced
• wherein the first sensor is a microswitch,
• the first intermediate member includes a contact portion for contacting the microswitch to bring the microswitch into an ON state when the first intermediate member is displaced,
• the at least one pressed portion includes pressed portions respectively provided at at least two positions respectively corresponding to positions of the at least two first attachment portions, and
• the contact portion is provided at a position different from the at least two positions respectively corresponding to the positions of the at least two first attachment portions in a circumferential direction.
