Abstract To provide an optical pickup device which obviates an increase in a cost, has a good assembly characteristic and is not deteriorated in performance against impact during the transportation of an optical disk device even if a carriage composed of thin parts, such as a sheet metal carriage in particular, is used. A main shaft 27 is inserted into round holes 21i and 21i and a first notched groove 21g is slidably supported by a sub-shaft 28, by which the carriage 21 is slidably supported. The front end of a second side wall part 21e is provided with a second notched groove 21h and a spacing is disposed between this second notched groove 21h and the sub-shaft 28. As a result, the carriage 21 is so regulated as not to be deformed more than this spacing.
