[Problem] To provide a surfing wave-making apparatus that is capable of making the so-called tubular plunging breakers which are suitable for surfing, and which have continuous crests ranging from a collapse stage to a stage immediately before collapse. [Solution] The present invention is provided with: a container body 110 that is open at the front thereof, is equipped with at least a bottom part and lateral plates, and is capable of trapping water in part of the interior space thereof; and a transfer path 120 that allows the container body 110 to travel thereon and that is equipped with an inclined-surface track 121 and an intra-pool track 123. The container body 110 falls along the inclined-surface track 121, plunges into water of the pool as a result of a free-fall motion, and travels on the intra-pool track 123 in the direction of a play area of the pool in a state of at least partially being submerged below the waterline of the pool. As the container body 110 decelerates, only the water held thereinside is thrust forward in the form of an isolated traveling wave 202 so as to produce a plunging breaker suitable for surfing.

[Problem] To provide a wave-making apparatus for surfing which is capable of making a so-called tubular plunging breaker which is suited to surfing and in which a wave crest is connected from a breaking area to an area about to break. [Solution] The wave-making apparatus comprises: a water carrier 110 which is opened at the front, includes at least a bottom and a side surface plate, and is capable of retaining water in a portion of an inner space thereof; a support structure 120 which supports the water carrier 110; and a carrying system device 130 which moves the water carrier 110 forward at a predetermined speed. The water carrier 110 is supported by being lowered into a pool with at least a portion of the water carrier 110 below the waterline of the pool such that the front of the water carrier 110 faces the play area of the pool. The carrying system device 130 moves the water carrier 110 forward along a track extending forward toward the play area with a portion of the water carrier 110 kept below the waterline. The water retained in the water carrier is carried forward and discharged, thereby pushing out a solitary traveling wave suitable for surfing toward the front to form a plunging breaker.

[Problem] To provide recreational equipment for ski jumping that is provided with a landing section artificially similar to a curved surface of a snow surface and can ensure safety by sufficiently absorbing impact. [Solution] Recreational equipment for ski jumping comprises: an approach section (110) that comprises an in-run face (116) and a take-off (117) and comprises an artificial curved face that allows the run-up to the take-off to be performed smoothly; and a landing section (120, 130, 140, 150, 160) that comprises an air mat filled with air and a blowing device that sends air into the air mat and for which at least a portion of the air mat surface is a landing and a slope for gliding and decelerating. The slope shape can be maintained by way of providing a plurality of partition membranes (133) that join the upper face of an inner wall and the lower face of an inner wall inside the air mat in the landing section, even when the air pressure inside the air mat is increased. The air in the air mat can be efficiently moved and dispersed internally so as to ease the impact.
