A support device includes a body and a positioning device mounted on the body for coupling with a fishing reel. A longitudinal hole for receiving a fishing rod extends from a front end through a rear end of the body. A gripping portion is provided on the rear end and includes a coupling portion for coupling with the fishing reel. A finger of a user can grip the front section and can touch a surface section of the fishing rod via a lower opening in a front section of a lower side of the gripping portion. Another finger of the user can grip the rear section and can touch another surface section of the fishing rod via a lateral through-hole formed in a rear section of the lower side and extending from a left side through a right side of the body.
