A fishing reel comprising: a spool that is rotatably supported between left and right side plates (1A, 1B) of a reel body; and a level wind device including a fishing line guide body through which a fishing line unreeled from the spool is threaded and which reciprocates between the left and right side plates (1A, 1B) in front of the spool in conjunction with the rotation of a handle, wherein the fishing line guide body includes a fishing line threading section that forms an opening (65, 68) through which the fishing line is threaded, and a fishing line guide section (70, 70A) which is formed so as to be narrower than the fishing line threading section and guides the fishing line to the spool by coming into contact with the fishing line, said fishing line guide section (70, 70A) being provided at a portion of an upper wall of the fishing line threading section which is close to the spool, the fishing line guide body is adapted to be rotatable in a front and rear direction, characterized in that: the fishing line guide body is rotatable forward causing the fishing line threading section to stand up in the vertical direction during the unwinding of the fishing line when the fishing line guide body is rotated forward, and the fishing line guide body is rotatable rearward causing the fishing line threading section to fall down during the winding of the fishing line when the fishing line guide body is rotated rearward, so that the fishing line guide section (70, 70A) comes into contact with the fishing line threaded through the fishing line threading section. a spool that is rotatably supported between left and right side plates (1A, 1B) of a reel body; and a level wind device including a fishing line guide body through which a fishing line unreeled from the spool is threaded and which reciprocates between the left and right side plates (1A, 1B) in front of the spool in conjunction with the rotation of a handle, wherein the fishing line guide body includes a fishing line threading section that forms an opening (65, 68) through which the fishing line is threaded, and a fishing line guide section (70, 70A) which is formed so as to be narrower than the fishing line threading section and guides the fishing line to the spool by coming into contact with the fishing line, said fishing line guide section (70, 70A) being provided at a portion of an upper wall of the fishing line threading section which is close to the spool, the fishing line guide body is adapted to be rotatable in a front and rear direction, characterized in that: the fishing line guide body is rotatable forward causing the fishing line threading section to stand up in the vertical direction during the unwinding of the fishing line when the fishing line guide body is rotated forward, and the fishing line guide body is rotatable rearward causing the fishing line threading section to fall down during the winding of the fishing line when the fishing line guide body is rotated rearward, so that the fishing line guide section (70, 70A) comes into contact with the fishing line threaded through the fishing line threading section. the fishing line guide body is rotatable forward causing the fishing line threading section to stand up in the vertical direction during the unwinding of the fishing line when the fishing line guide body is rotated forward, and the fishing line guide body is rotatable rearward causing the fishing line threading section to fall down during the winding of the fishing line when the fishing line guide body is rotated rearward, so that the fishing line guide section (70, 70A) comes into contact with the fishing line threaded through the fishing line threading section.
