PROBLEM TO BE SOLVED: To provide an adjusting device of an optical pickup transport mechanism where the mounting height of shaft members, such as a guide shaft and a screw shaft are easily adjusted, without impeding thinning. SOLUTION: This device is provided with an adjustment bracket 15 which has a shaft end supporting part 15a for supporting one end 10a of a screw shaft 10 being a shaft member and a supporting point part 15g acting as a oscillating center, a restraining means of a louvered part 12 or the like which restrains the supporting point part 15g of the adjustment bracket 15 to a mechanism chassis 11, a regulating means of a guide pin 13 or the like which contacts slidingly to the adjustment bracket 15 and regulates its oscillation direction, a spring member of a helical spring 14 or the like which energizes the adjustment bracket 15 in a direction in which the bracket 15 is separated from the mechanism chassis 11 and an adjusting screw 16 which is screwed in a screwing part 11a formed in the mechanism chassis 11 and connects the adjustment bracket 15 with the screwing part 11a. By performing screwing forward and back of the adjusting screw 16 with regard to the screwing part 11a, the adjustment bracket 15 oscillates centering on the supporting point part 15g and the one end 10a of the shaft member raises and lowers with regard to the mechanism chassis 11 with oscillation operation.
