摘要： PROBLEM TO BE SOLVED: To provide an ashtray, which is produced at a reduced cost, suitable for effective utilization of a space, elastically deformed and hard to be broken, and allows the ashtray body to be easily and quickly taken out from the outer box. SOLUTION: This ashtray comprises an ashtray body 20 of a material which can be elastically deformed, and put in an external box 11. The ashtray body 20 is formed into a shape almost coinciding with the inside of the external box 11, and is provided with a projection 26 protruding from each of its sides 23. The external box 11 is provided with a long slit 17 in each of its sides 13, to securely hold the ashtray body 20 therein, with each of the slits 17 receiving each of the projections 26, to guide the ashtray body 20 in the direction in which it is attached to or detached from the external box 11, and to prevent the ashtray body 20 from coming off the external box 11.

摘要： PURPOSE: To dispense with a backlash preventing means by providing the device with a wire for control which constrains a backrest part by rocking a control lever supported with a piston rod by an energizing force. CONSTITUTION: When the backrest part is set almost in a perpendicular posture, the stretching force of the wire 3 for control is transmitted to the control lever 47, and the backrest part is set in a tiltable state by rocking the control lever 47 to a constrain canceling position against the energizing force. At this time, the main body of a cylinder 41 for lock and the piston rod 43 are connected to a sitting part 11 and the backrest part, respectively, which prevents backlash from occurring in the backrest part. The backrest part is tilted to a reclining posture by a leaning force, and it is interlocked with the cylinder 41 for lock. When the piston rod 43 retracts relatively on the main body of the cylinder 41 for lock, no stretching force of the wire 53 for control is transmitted to the control lever 47, and the backrest part is set in a constrained state by rocking the control lever 47 to a constrained position by the energizing force. In this way, the backrest part is disabled to tilt, and it is constrained in the reclining posture.

摘要： PROBLEM TO BE SOLVED: To comfortably receive medical treatment in a relaxed posture and without anxiety while varying the height and angle of an arm rest linked with the tilting operation of a seat back so as to reduce the physical and mental burden of a patient in any state of sitting, reclining and lying on his/her back and so as to avoid giving his/her anxiety that he/she might fall down at the time of moving his/her body in the lying state. SOLUTION: This arm rest 8 is provided on the upper surface of a side panel 7, which is provided in the state of being freely rotatable and movable up/down to a leg part 3 and the seat back 6. At the time of tilting the seat back 6 backward with a spindle 14 as a rotary supporting point, the panel 7 is gradually lowered while rotating with a connecting pin 25 as a rotary supporting point. When the seat back 6 comes into a nearly horizontal bed state, the side panel is inclined by lowering downward at an inclining angle 6 to 14 and the rear end side of the arm rest 8 becomes nearly at the same height as a bed surface.
