A water jacket spacer is inserted into a water jacket. The water jacket spacer comprises an expansion member, a plate-shaped holder to which the expansion member is fixed, and a leaf spring that abuts the inner wall of the water jacket. The leaf spring projects from a face on the holder on the side opposite of the expansion member. The holder curves to match the shape of the water jacket. The position of the water jacket spacer in the water jacket is maintained by the biasing force of the leaf spring.

A spacer (1) is injection molded by using an injection molding die having resin flow channels that are designed such that a plurality of gates (6) are arranged along the longitudinal direction at a position corresponding to the outer peripheral surface of a side wall part (4) in which a plurality of arc-like peripheral surface parts (2) are connected through a waist part (3). After opening the mold and ejecting the spacer, the spacer is cooled with a runner (7) being connected to the gate (6), and thereafter, the runner (7) is cut off. As a result, when producing a water jacket spacer that is assembled to the inside of the water jacket and controls the flow of cooling water by injection molding, while producing with a high productivity without being affected by design constraints caused by draft angle, deformation in the post-molding cooling step is prevented.

Inorganic fibers including the following composition, SiO_(2), MgO and CaO being main components: SiO_(2): 73.6 wt% to 85.9 wt%, MgO: 9.0 wt% to 21.3 wt%, CaO: 5.1 wt% to 12.4 wt%, Al_(2)O_(3): 0 wt% or more and less than 2.3 wt%, and Fe_(2)O_(3): 0 wt% to 0.50 wt%.


Provide is a heat-resistant roll with improved effectively characteristics, a production method thereof, and a method of producing sheet glass using the heat-resistant roll. A method of producing a heat-resistant roll equipped with a roll portion containing 5% by weight or more of clay includes: a grinding step (S101) of grinding a roll surface of the roll portion; and a surface treatment step (S102) of performing surface treatment of smoothening the ground roll surface in a wet state.
