To provide a camera in low-cost structure which makes it easy to build in a gear train for a finder transmitting rotation to a zoom finder device.

A gear train 45 for zooming and an interlocking mechanism 47 for the finder are built in the front of a film take-up chamber 36 of a main body base part 3. The gear train 45 for zooming is fitted by being pivoted on the front of the film take-up chamber 36. A gear cover 57 nearly in a plate shape is fitted to the front of the gear train 45 for zooming to cover the gear train 45 for zooming. The gear cover 57 has a gear fitting part 58 for the finder formed integrally so that it projects from the front part 57a covering the gear train 45 for zooming toward nearby the fixed cylinder 34. The gear fitting part 58 is fitted with an intermediate gear train 54 constituting the interlocking mechanism 47 for the finder.
