Abstract: A pillow device which supports a head portion of a user during sleep includes a pillow main body, a microphone, which is provided in the pillow main body and detects a snore of the user, a vibrator, which operates in response to the snore detected by the microphone and moves the pillow main body, a pressure detecting switch, which is provided in the pillow main body and detects a change in pressure exerted on the pillow main body when the user moves the head portion, and a gate circuit, which inhibits the vibrator from operating for a predetermined period of time, when the pressure detecting switch detects a change in pressure exerted on the pillow main body.

Abstract: A snore recording pillow includes a pillow main body, and microphones provided in the pillow main body and connected to a recorder.

Abstract: A fixed rod member is provided integrally with at least both sides of the lateral direction of the periphery of a bendable spring unit. A hinge mechanism is provided at the end portion of the fixed rod member. The hinge mechanism is connected by a movable rod member provided integrally with the periphery of at least one end portion of the spring unit. Thus, one end portion of the spring unit is configured to be bent together with the movable rod member.

Abstract: A vehicle body is provided with a rear wheel at a rear portion, and a front wheel coupled to a handle post. A swing-enabling shaft is rotatably provided on the upper portion of the handle post. A handlebars unit is attached to the swing-enabling shaft such that it can swing forward and backward relative to the vehicle body. When the handlebars unit is swung, a driving mechanism is driven. The driving mechanism rotates the front wheel such that the vehicle body advances, regardless of whether the handlebars unit is swung forward or backward.

Abstract: A bedplate is disposed in a bed frame. The bedplate includes a fixed bed part, right leg-raising parts and left leg-raising parts. The fixed bed parts are secured to the bed frame. The right leg-raising parts are rotatably coupled, at one end, to one end of the fixed bed part. The left leg-raising parts are rotatably coupled, at one end, to the end of the fixed bed part. Said ends of the fixed bed part are spaced in the transverse direction of the bed frame. A bed part driving mechanism is provided on the lower surface of the bedplate. The mechanism drives one or both of the leg-raising parts of either pair, in a rising direction.
