Table and method of assembling the same

A table comprising:

• a pair of leg portions, and each of the leg portions has a length in a vertical direction and is hollow in shape with an opening formed at a top end thereof;
• a frame member that couples the pair of leg portions, at least a part of the frame member being formed as a cylindrical portion of cylindrical shape;
• a top panel that is rotatable about the cylindrical portion;
• a pair of casters, at least one of the pair of casters being provided at each of a front and a rear of a base portion of each leg portion;
• a contact portion provided on the base portion of each leg portion;
• and
• a raising/lowering mechanism that couples a movable portion, which is either one or more of the pair of casters and the contact portion, to the top panel, and switches which of the pair of casters and the contact portion comes into contact with a floor surface by raising/lowering the movable portion in accordance with a rotation of the top panel,
• wherein the raising/lowering mechanism comprises:
• a top-panel-coupling member that is coupled to the top panel;
• a rod that is arranged inside each leg portion and is coupled to the movable portion;
• a support shaft that is fixed to each leg portion in parallel with an axis line of the cylindrical portion;
• a rotary member that is rotatably supported by the support shaft and is coupled to the top-panel-coupling member and to the rod, and
• the support shaft is arranged substantially coaxially with the cylindrical portion.

• a contact portion provided on the base portion of each leg portion;
• and
• a raising/lowering mechanism that couples a movable portion, which is either one or more of the pair of casters and the contact portion, to the top panel via the opening, and switches which of the pair of casters and the contact portion comes into contact with a floor surface by raising/lowering the movable portion in accordance with a rotation of the top panel,
• wherein a first end of the raising/lowering mechanism extends through and partially projects out from the opening formed at the top end of each of the leg portions, and the raising/lowering mechanism comprises:
• a top-panel-coupling member that is coupled to the top panel;
• a rod that is arranged inside each leg portion and is coupled to the movable portion;
• a support shaft that is fixed to each leg portion in parallel with an axis line of a rotation axis of the top panel;
• and
• a rotary member that is rotatably supported by the support shaft and is coupled to the top-panel-coupling member and to the rod, and
• the method of assembling the table comprises steps of:
• preliminarily assembling the top-panel-coupling member on either one of the top panel or the rotary member;
• and
• coupling the raising/lowering mechanism and the top panel by inserting the top-panel-coupling member into an inserted portion formed on another of the top panel and the rotary member in such a manner as to move the top-panel-coupling member in parallel with the axis line of the rotation axis of the top panel.
