A method of repairing a tire is a method to repair a damaged part of the tire, the damaged part being a part in a rubber layer of a tire side section located between a carcass ply and a tire surface and terminated within the rubber layer. The method of repairing the tire includes: a first step of opening the damaged part while in a state the tire is retained; a second step of injecting or applying an adhesive to the damaged part; a third step of releasing a damaged-part-opened state and bonding mutually opposing wall surfaces of the damaged part.

Provided is a golf swing classification method that is capable of optimizing selection of a golf club. A golf swing classification method when a golf club hits a golf ball according to the present invention includes the steps of: acquiring acceleration in at least a single point on the golf club or in at least one point that follows the single point during the golf swing; and mapping a behavior of the golf club based on a time period from a time point when an absolute value of the acceleration is at a maximum to a time point when the golf club hits the golf ball.

Provided is a swing simulation system capable of simulating a swing without amplifying errors contained in measured values on three-dimensional coordinates of a grip during the swing. The simulation system according to the present invention includes: at least two imaging devices for imaging identification features capable of identifying a closed virtual plane that follows a grip of a golf club during a swing; and a simulation apparatus for simulating a behavior of the golf club during the swing, based on position information on the virtual plane.

A sealing and pump-up device capable of suppressing sealing agent contained in a sealing agent container body from leaking and preventing damage to a casing body even if an operator mistakenly attempts to remove the sealing agent container body. A connection bodyis retained to a seal opening deviceby fitting force between first clawsA and a leg portionand between second clawsA and the leg portion. An operator might conceivably mistakenly attempt to remove a liquid agent containerfrom the seal opening device. However, the fixing force of the screwin the circular holeis determined by such factors as the shape of each member so as to be weaker than the sum of the fitting force (retaining force) between the first clawsA and the leg portionand the fitting force (retaining force) between the second clawsA and the leg portion. Accordingly, fixing of the screwin the circular holeis released if an operator attempts to remove the liquid agent containerfrom the seal opening device, and the sealing agentcontained in the liquid agent containercan be suppressed from leaking and damage to the casing bodycan also be prevented.
