PROBLEM TO BE SOLVED: To obtain a recorder having such a structure as the bearing part is partially carried on a guide shaft in which vibration of a carrier is suppressed at the time of traveling without increasing the number of components by taking advantage of the fact that the bearing part is partially carried on the guide shaft. SOLUTION: The tubular bearing part 2 of a carrier 1 is fitted slidably over a rod-like guide shaft 3. The bearing part 2 is made of metal and provided, at an upper part in the inner circumferential surface 21 thereof, with a groove part 22. Contact parts 23 and 23 formed by the opposite edges of the groove part 22 are carried on the outer circumferential surface 31 of the guide shaft 3 at two points in the circumferential direction and a part 31a close to the top of the outer circumferential surface 31 of the guide shaft 3 is contained in the inner space of the groove (recessed space) P. |
