As shown by the chain double-dashed line, the fixing screw hole 20
The rotary part operating screw 20-1 attached to c is removed, attached to the removal screw hole 20d, and tightened. By doing this, the tip of the rotating portion operating screw 20-1 becomes V of the taper shaft 1.
Since the slope of the groove 1a on the side of the tripod is pushed, the rotating portion 2 comes off the taper shaft 1 and returns rotatably.

A tripod for a camera, which is composed of a tapered hole surrounded by a conical inner wall that fits the shaft and is assembled by inserting a tapered shaft into the tapered hole, is extremely easy to disassemble and disassemble. However, with a tripod for a camera having such a connecting portion, it takes a lot of time to attach and detach the camera and set it, and the taper shaft is tightly fitted into the taper hole and fixed during use. There was a problem that was stuck.

Fixing screw hole toward the inclined surface on the side of the section, and a horizontal rotation member having a U-shaped insertion groove in the vicinity of the other end, and a rotation attached to the fixing screw hole (20c). (B) a substantially cylindrical member, which is rotatably fitted coaxially to the horizontal rotation member and is fixed in a substantially central portion on the side of the tripod. A tapered shaft corresponding hole is provided so that rotation is not hindered by the tapered shaft of the tripod, On the side of the camera mounting portion, a deep cutout portion is axially cut from one end, and the end portion provided with the cutout portion has a through hole with the cutout portion sandwiched therebetween. An operating rod mounting seat, a connecting member provided with a through hole provided coaxially with the through hole and a camera fixing member mounting shaft having a conical surface for coupling, and (c) a substantially rectangular plate shape having a camera fixing screw in the center. The camera fixed part,
A camera mounting member comprising a camera fixing member mounting shaft provided along an edge of one corner of the camera fixing portion, and a leg portion having a conical surface that conically connects, and (d) a head at one end,
The other end has a threaded portion, the leg portion of the camera mounting member which is conically coupled to each other, the through hole of the connecting member, and the through hole of the operating rod mounting seat are movably in the axial direction and the central axis. There is a non-rotatable mounting shaft around and a screw part that (e) is connected to the screw part of the mounting shaft protruding from the through hole of the operating rod mounting seat, and cooperates with the mounting shaft to mount the camera. This is achieved by the above-mentioned tripod for a camera, which comprises an operating rod for loosely and loosely connecting the member and the connecting member to the rotating member. Further, in addition to the above, the object of the present invention is to provide a V-shaped groove provided on the taper shaft of the tripod on the end face of the lateral rotation member opposite to the end face on which the detachment screw hole is provided. This can be achieved more reliably by providing a disengagement screw hole into which the rotating portion operation screw can be screwed, in a position facing the tripod side slope.
