<p>A game apparatus manufacturable at low cost, requiring less installation space, and allowing infants to freely use it for diversifying game apparatuses presented for infants. The game apparatus (1) comprises a supporting base (2) properly disposed on an installation plane (G), a sheet body (10) loosely hooked to the supporting base (2) so that a closed space (15) can be formed in the clearance thereof from the supporting base (2), an air feed mechanism (20) feeding the outside air into the closed space (15), and a drive device (30) disposed on the supporting base (2) in the closed space (15), having hooking members (33, 36) hooked to the inner surface of the sheet body (10), and reciprocating these hooking members in both a direction toward the inside of the closed space (15) and a direction toward the outside. When the outside air is fed into the closed space (15), the sheet body (10) is inflated outward in a tensed state, and when the hooking members (33, 36) of the drive device (30) are reciprocatingly moved, the sheet body (10) is recessed inward or inflated outward.</p> |
