Abstract: The present invention provides a lens holder comprising a third group frame that serves as a holding member which holds lenses, a guide shaft that supports the third group frame when the third group frame is moved along the optical axis of the lenses, a rear barrel part perpendicularly to which the guide shaft is locked, a first bearing member that is molded as an integral part of the rear barrel part in order to bear the end of the guide shaft distal to the rear barrel part, and a guide shaft presser that when the first bearing member bears the end of the guide shaft distal to the base, bears the end of the guide shaft proximal to the rear barrel part. Moreover, the present invention provides a lens barrel and an imaging apparatus that employ the lens holder. Consequently, the structure of a bearing that bears a shaft which supports the lens holding member when the lens holding member is moved along the optical axis of the lenses is downsized. Moreover, the bearing bears the shaft highly precisely.

Abstract: PROBLEM TO BE SOLVED: To put the main part of a mechanism in space equivalent to the moving range of a lens cover and to improve space efficiency by providing a lever rotatably attached to either of pinion gears and an energizing member, etc., energizing the lever in one direction. SOLUTION: One end side of the lever 14 is turnably attached to a position deviated from a center on the pinion gear 10 through a pin 15a. The other end side of the lever 14 is attached to slide in a cam groove 16 provided on a sheet metal 9 through a pin 15b. A hook part 17 is provided on the lever 14 and a tension spring 19 is stretched and laid between the hook part 18 formed on the sheet metal 9 and the hook part 17. The spring 19 energizes the lever 14 in a direction where the hook part 17 of the lever 14 is made to approach to the hook part 18 of the sheet metal 9. Thus, the main part of the mechanism is put in the space equivalent to the moving range of the lens cover and the space efficiency is improved.
