At least a part of the holding unit is provided with a dividing line 300 formed by a housing and a lid member. The clearance of the dividing line has a first clearance 260 and a second clearance 261 different in size from the first clearance.

  Preferably, the second clearance is greater than the first clearance. Also preferably, the first clearance is formed between the convex portion (270, 271) provided on one of the housing and the lid member, and the other plane (201a, 201b) of the housing and the lid member facing the convex portion. Is formed. The second clearance is formed by a plane of the housing and a plane of the lid member facing the plane of the housing. Also preferably, the convex portion forming the first clearance includes the first convex portion 270 and the second convex portion 271 within the range of the dividing line. Also preferably, the projection forming the first clearance includes at least two or more projections within the range of the dividing line. More preferably, the accessory has a rotation axis (lid member rotation axis 238) for rotating the lid member. The first convex portion is provided at a position closer to the tip of the hold portion than the rotation shaft. The second convex portion is provided at a position closer to the rotation axis than the tip of the hold portion. More preferably, the accessory has an opening spring 239 provided so as to penetrate the rotation shaft. The lid member is urged toward the tip of the holding portion by the urging force of the opening spring.

Preferably, clearance Δα262 and clearance Δβ263 have different sizes from each other. More preferably, clearance Δα262 is smaller than clearance Δβ263. Further, preferably, the lid member is disposed in the closed position in the insertion / extraction direction (including substantially the insertion / extraction direction) of at least one of the battery and the medium inserted into the camera body. According to the present embodiment, operability is impaired. It is possible to provide an accessory (extended grip) and an image pickup apparatus capable of maintaining or improving the holdability without any need.

  As described above, the preferred embodiments of the present invention have been described, but the present invention is not limited to these embodiments, and various modifications and changes can be made within the scope of the gist.
