A rowing bike operated in a manner similar to a rowing boat. The guide catheter has a proximal portion and a distal portion formed into a preformed shape configured such that the distal portion of the shaft is supported on a wall of the superior vena cava during insertion of the distal portion into the coronary sinus. In this case, an operation sound generation section acquires an operation sound different from the normal one from an operation sound ROM, and a sound signal superimposing section superimposes the different operation sound onto a sound signal which is to be outputted from a speaker. The organicinorganic composite can be with admixed with a suitable continuous phase, depending on the type of the organic component, to provide a fire-resistant coating material. Light emerges radially outward in all directions from the diffuser. The photosensitive resin composition includes a specific alkali-soluble resin, a compound containing ethylenic unsaturated group, a photoinitiator, and an organic solvent.
