ABSTRACT:
A pickup head is provided with a second shaft receiving section. A cutout is formed in the second shaft receiving section. A sub shaft supports the pickup head in a movable manner via the second shaft receiving section. A diameter of the sub shaft is smaller than the size of the cutout. A retainer is attached between the second shaft receiving section and the sub shaft. The retainer includes a body section and a pressing section. The body section enters the cutout in a state that a slide groove of the body section slidably fits to the sub shaft. The pressing section is elastically deformed upon contact with the sub shaft when the body section enters the cutout, and biases the second shaft receiving section via the body section such that a lower surface of the cutout is pressed against the sub shaft.
