Fastening tool

A fastening tool that is configured to fasten workpieces via a fastener having a pin and a cylindrical part, comprising:

• a tool body;
• a motor that is housed in the tool body;
• a pin gripping part that is configured to grip the pin, the pin gripping part being operably connected to the motor and configured to be moved relative to the tool body between a frontmost position and a rearmost position along a driving axis that defines a front-rear direction of the fastening tool, by power of the motor;
• a first detecting device that is configured to detect that the pin gripping part is located in a first detection position between the frontmost position and the rearmost position in the front-rear direction;
• a first abutment part that is configured to move integrally with the pin gripping part relative to the tool body in the front-rear direction;
• a second abutment part that is provided within the tool body and configured to position the pin gripping part in the frontmost position by abutting on the first abutment part when the pin gripping part is moved forward to the frontmost position;
• a second detecting device that is configured to detect abutment between the first abutment part and the second abutment part;
• and
• a control device that is configured to control driving of the motor;
• wherein:
• the pin gripping part is configured to fasten the workpieces via the fastener by moving rearward from the frontmost position, and
• the control device is configured to decelerate the motor when the first detecting device detects that the pin gripping part reaches the first detection position in a process of moving forward, and to thereafter stop the motor when the second detecting device detects abutment between the first abutment part and the second abutment part.
