Abstract
An illuminating angle adjusting apparatus for an electronic flash device is capable of adjusting the illuminating angle of the electronic flash device in response to drive of a motor smoothly and accurately by a combination of a guide groove and a guide rail provided almost in the same vertical position as a rack gear of a zooming frame and an output gear of a transmission mechanism engaged with one another. A driving force produced by the motor is transmitted to the zooming frame through the engagement of the output gear and the rack gear to move the zooming frame relative to a light emitting portion of the electronic flash device with the same being guided by the guide groove and the guide rail. The movement of the zooming frame causes the change in the illuminating angle of the electronic flash device as it carries a lens at a front portion thereof.
