Abstract: Provided is a stretching mat whereby high stretching effects are obtained relative to the conventional configuration. An air bag is provided to a stretching part for curving and protruding in a ridge shape along a front-rear direction, and transformation is possible between a gently curved state in which the air bag is deflated and a strongly curved state in which the airbag is swollen and more strongly curved than in the gently curved state. A configuration is also adopted in which air is supplied to the air bag in a state in which a portion of a body is resting on the stretching part, and the stretching part transforms from the gently curved state to the strongly curved state over time, after which the supply of air is stopped and the strongly curved state of the stretching part is maintained.

Abstract: Provided is a stretch exercise tool whereby muscles around the vertebrae can be uniformly extended. A stretch exercise tool provided with a stretching part the upper face of which projects into a crest type along the longitudinal direction and on which a user's body is placed with facing upward and extended, wherein the stretching part is configured of multiple body-supporting ribs in the width direction, said ribs being disposed along the longitudinal direction. According to this configuration, when the user's body is placed on the stretching part, a force in the longitudinal direction, said force acting to topically extend the body, is applied to the body at each interval among the ribs. Thus, the body can be uniformly extended compared with the conventional configurations.

Abstract: Provided is footwear whereby it is possible to desirably carry out correction and stretching of a transverse arch of a foot. A transverse arch pressure part which protrudes such that a cross-section in the width direction is an arc shape is formed between portions in a foot contact surface of an article of footwear directly below the ball of the large toe and the ball of the little toe, and a pair of runners which do not support the ball of the large toe or the ball of the little toe are formed in the foot contact surface directly below the ball of the large toe and the ball of the little toe.

Abstract: A stick that is excellent in shock absorption and is also excellent in stability is provided. A stick body is provided with a telescopic extension pipe formed by fitting an outer tube and an inner tube together in a nesting manner. Inside the extension pipe, a velocity-dependent damper that damps the relative sliding movement between the outer tube and the inner tube, and a compression coil spring that concentrically fits onto the damper and urges the extension pipe so as to be extended are connected in parallel. According to such a stick, the shock transmitted to the hand can be mitigated as the compression coil spring contracts upon landing. Also, since the damper suppresses unwanted vibration of the extension pipe, the length of the stick quickly becomes stable after landing, allowing the user to keep stable balance with the stick.
