A bottle strut *taiheizuka 大瓶束, with a sculptural decoration called oigata 笈形 affixed on both sides. Also oigatatsuki taiheizuka 笈形付大瓶束 (the oigata shape added to a bottle strut). This strut was also called *gasshōhire 合掌鰭 in the Daiku hinagatabon 大工雛形本 (The Carpenter's Book of Patterns), Edo period. It is usually positioned on a rainbow beam *kōryō 虹梁. Its function is to receive the bearing block *masu 斗, on which an upper beam can be supported.
These struts vary from simple and undecorated ones to those with exceedingly intricate carvings on each side.
