A rocking chair includes a seat, a backrest that is tiltable rearward, a locking spring portion that imparts resistance to the rearward tilting of the backrest, and a resilience adjustment member that changes the degree of resistance of the spring portion to the rearward tilting of the backrest. The resilience adjustment member is a cam that is rotationally operable by a person seated on a seat and the position in which rocking load due to the rearward tilting of the backrest is applied to the spring portion is changed by the cam, so that moment applied to the spring portion changes and the degree of resistance of the spring portion is adjusted.

Rocking chair and spring unit used therein

The present invention provides a photocurable composition which contains a photobase generator capable of generating a satisfactory amount of a base in a high quantum yield when irradiated even with a small quantity of light for a short time, and contains a curable compound that is rapidly cured by the generated base such that the composition is cured into a cured product. The photocurable composition comprises: a photobase generator (A) which is a salt of a carboxylic acid (a1-1) represented by the following formula (1-1) with a basic compound (a2), and a curable compound (B) which has, in one molecule thereof, at least two functional groups selected from among epoxy group, (meth)acryloyl group, isocyanato group, acid anhydride group, and alkoxysilyl group, where R1 to R7 in the above formula (1-1) each are hydrogen or an organic group, R1 to R7 may be the same or different, and two of R1 to R7 may be bonded to each other to form a ring structure.
