A buckle device is provided with a lock plate that engages with a tongue plate that is inserted into the device body and that holds the tongue plate inside the device body, and a lock member that engages with the lock plate and prevents the lock plate from moving to a released position, and the lock member has a body portion and a shaft that supports the body portion within the device body. The body portion of the lock member is formed from a sintered metal, and the shaft is formed from a metal and is integrally press fit into the body portion. The strength of the shaft, which receives the load of the body portion, is secured and at the same time it is possible to achieve miniaturization and weight securement of the body portion.

What is claimed is: 1. A buckle device, comprising: a lock plate provided so as to be movable between an engagement position, at which the lock plate engages with a tongue plate inserted into a body of the device and holds the tongue plate within the body of the device, and a released position, at which the lock plate has been released from holding the tongue plate; and a lock member having a body portion provided so as to be able to oscillate between a locking position, at which the body portion engages with the lock plate positioned at the engagement position and prevents the lock plate from moving toward the released position, and an unlocked position, at which the body portion has been released from preventing movement of the lock plate, and a shaft that supports the body portion at the body of the device, wherein the body portion is formed from a sintered metal and the shaft is formed from a metal and is integrally press fit into the body portion. 2. The buckle device of claim 1, further comprising: a release button that is provided at the body of the device and that causes the body portion of the lock member to oscillate toward the unlocked position when the release button is operated by being pressed; a lock spring that is provided between the release button and the body portion of the lock member and that urges the body portion of the lock member toward the locking position; and a holder, formed from a resin, that is provided between the body portion of the lock member and the lock spring and is engaged with one end of the lock spring. 3. The buckle device of claim 1, wherein the metal includes stainless steel. 4. A buckle device, comprising: a lock plate provided so as to be movable between an engagement position, at which the lock plate engages with a tongue plate inserted into a body of the device and holds the tongue plate within the body of the device, and a released position, at which the lock plate has been released from holding the tongue plate; and a lock member having a body portion provided so as to be able to oscillate between a locking position, at which the body portion engages with the lock plate positioned at the engagement position and prevents the lock plate from moving toward the released position, and an unlocked position, at which the body portion has been released from preventing movement of the lock plate, and a shaft that supports the body portion at the body of the device, wherein the body portion is formed from a sintered metal and includes a recess for non-rotatably receiving said shaft. 5. The buckle device of claim 4, wherein the shaft is formed from a metal and is integrally press fit into the body portion. 6. The buckle device of claim 5, wherein the metal includes stainless steel. 7. The buckle device of claim 4, further comprising: a release button that is provided at the body of the device; a lock spring that is provided between the release button and the body portion of the lock member; and a holder, formed from a resin, that is provided between the body portion of the lock member and the lock spring. 8. A buckle device, comprising: a lock plate provided so as to be movable between an engagement position, at which the lock plate engages with a tongue plate inserted into a body of the device and holds the tongue plate within the body of the device, and a released position, at which the lock plate has been released from holding the tongue plate; a lock member having a body portion provided so as to be able to oscillate between a locking position, at which the body portion engages with the lock plate positioned at the engagement position and prevents the lock plate from moving toward the released position, and an unlocked position, at which the body portion has been released from preventing movement of the lock plate, and a shaft that supports the body portion at the body of the device; a release button that is provided at the body of the device and that causes the body portion of the lock member to oscillate toward the unlocked position when the release button is operated by being pressed; a lock spring that is provided between the release button and the body portion of the lock member and that urges the body portion of the lock member toward the locking position; and a holder, formed from a resin, that is provided between the body portion of the lock member and the lock spring and is engaged with one end of the lock spring.
