[2. effect]
According to the embodiment detailed above, the following effects can be obtained.
(2a) The display section 50 is provided at the rear end of the rear section 40. According to such a configuration, the display section 50 is provided at a position away from the back plate 30. Therefore, even when the user is seated on the chair 1 and leaning against the back plate 30, it is possible to prevent the user's clothes from covering the display section 50 and hiding the display section 50. Therefore, the display section 50 can be provided at a position with better visibility.

(2b) A depression is provided on the lower surface of the rear part 40, and the user can use the rear part 40 as a handhold by placing his or her hand in the depression. According to such a configuration, since the display section 50 is provided on the handle, there is no need to separately provide a structure for arranging the display section 50.

(2c) The display section 50 has a shape that protrudes toward the rear side along the curved shape of the upper pipe 153. According to such a configuration, when the upper pipe 153 is used as a handle, it is possible to reduce the uncomfortable feeling that the corner of the display part hits the hand.

(2d) The display section 50 is provided on the upper pipe 153. The upper pipe 153 is formed of a metal pipe. This configuration is suitable for using the upper pipe 153 as a handle, and since the display section 50 is fixed to a hard metal, it is more convenient than the case where the display section 50 is fixed to a cloth or plastic material. This improves the fixing strength.

Further, the upper pipe 153 is curved so as to be convex toward the rear side. The groove 511 of the display section 50 is also curved so as to be convex toward the rear along the surface shape of the upper pipe 153. Therefore, when the curved upper pipe 153 enters the curved groove 511, it is possible to suppress the display unit 50 from rotating around the upper pipe 153. Therefore, the fixing strength of the display section 50 can be improved.
